Prevalence Of Bacteriuria Research Articles

Exploring risk factors and antimicrobial susceptibility patterns associated with bacteriuria among Syrian refugees in makeshift camps.

The health and well-being of refugees are critically compromised by harsh living conditions, which foster the emergence of infectious diseases and the misuse of antimicrobial agents. This multicentre cross-sectional community-based study investigated the prevalence of urine carriage of bacteria and the associated antimicrobial resistance patterns among Syrian refugees living in makeshift camps in Lebanon, an East Mediterranean country. We used multivariable logistic regression models to identify the risk factors associated with bacteriuria in this vulnerable population. Mid-stream urine samples were collected aseptically from 79 Syrian refugees; regardless of whether they exhibited symptoms of urinary tract infections. Samples were inoculated onto UriSelect™ 4 chromogenic agar and bacterial isolates were identified using MALDI-TOF-MS. Antibiotic susceptibility testing was assessed using the Kirby-Bauer disk diffusion assay. The prevalence of bacteriuria was 30.8% (95% CI: 21.6-41.7), and the etiologic agents were primarily Escherichia coli (80%), Klebsiella pneumoniae (12%), and Enterobacter cloacae complex (8%). The Enterobacterales isolates exhibited high resistance to penicillins (64%), cephalosporins (20-48%), and quinolones (28%), with 56% showing multidrug resistance. While the female sex and rubbish accumulation were risk factors, tea consumption, reduced chicken intake, and economic support were protective against bacteriuria. This report corroborates prior anecdotal evidence regarding underdiagnosed bacteriuria among Syrian refugees in Lebanon. The data highlight the pressing need for monitoring and awareness programs to curb the spread of infectious diseases and antimicrobial resistance in both refugee and host communities.

Prevalence of bacteriuria and bacterial resistance in adolescents from the center of the state of Tlaxcala, Mexico.

Urinary tract infections and bacteriuria are common in the pediatric population, and antibiotic resistance is increasing significantly. Recurrent urinary infections, symptomatic or asymptomatic, are a risk factor for developing chronic kidney disease in adolescents and young adults. This study aimed to assess the prevalence of bacteriuria diagnosed by culture to identify the main causal agents and sensitivity to antibiotics in adolescents from the central region of the state of Tlaxcala. A cross-sectional study was carried out among 905 adolescents from 11 to 18 years old who lived in the central region of the state of Tlaxcala, Mexico. Bacteriuria was evaluated by positive nitrites and leukocyte esterase, and urine culture with antibiogram. Multivariate logistic regression models were executed to evaluate the risk of presenting bacteriuria, with a confidence level of 95%. A total of 31 participants had a positive urine culture, with a bacteriuria prevalence of 3.4%, of which 29 cases were asymptomatic. The most frequent agent was Escherichia coli) in both sexes (28.6% in men and 29.7% in women) and regarding bacterial resistance: E. coli presented greater resistance to ampicillin, trimethoprim/sulfametoxazol and ceftriaxone. The risk factors associated with bacteriuria were female sex, sexual activity, use of contraceptives, and greater consumption of sweetened beverages. Bacteriuria is common in this adolescent population, so its early identification is necessary to treat it, and to prevent its complications.

Prevalence of bacteriuria and treatment outcomes in patients with symptomatic benign prostatic hyperplasia: a prospective observational study.

The global incidence of benign prostatic hyperplasia (BPH) is rising, with bacterial causes of lower urinary tract symptoms (LUTS) being a common factor contributing to complications in these patients. To identify the prevalence of bacteriuria and treatment response in patients with symptomatic BPH. This 1-year prospective study included all patients presenting with LUTS due to BPH who met the inclusion criteria. Urine samples were collected and analyzed for microscopy, culture, and sensitivity following standard protocols. Bacterial growth in urine specimens and International Prostate Symptom Score (IPSS) of LUTS were recorded before and after antibiotic therapy. A total of 131 patients with symptomatic BPH were studied. Escherichia coli (47.6%) was the most commonly isolated bacteria, followed by Klebsiella pneumoniae and Pseudomonas species. E. coli and Klebsiella showed the highest sensitivity to nitrofurantoin. After 1 week of antibiotic therapy, 69% of patients had sterile urine cultures, while 31% remained E. coli positive. Significant improvement in IPSS scores was observed after 1 week of therapy (P<0.05), and there was no significant change in urine culture (P=0.854). Bacteriuria is a common finding in patients with symptomatic BPH in our setting. Escherichia coli and Klebsiella pneumoniae were the most frequently isolated organisms, with sensitivity to nitrofurantoin and cefixime. A week of antibiotic therapy significantly reduced IPSS scores but did not reduce bacteriuria.

Occurrence of bacteremia, bacteriuria and bacteriuria-related bacteremia in dogs and cats with chronic kidney disease. A pilot study

In human medicine, major infections are the most significant and critical non-cardiovascular complications in patients affected by chronic kidney disease (CKD), with bacteriuria being the primary source of bloodstream infections and its evolution toward sepsis. The availability of data on prevalence of bacteremia and its association with bacteriuria in dogs and cats with CKD is limited. The aim of this observational cross-sectional study was to determine the occurrence of bacteremia, bacteriuria, and bacteriuria-related bacteremia in dogs and cats affected by CKD. Client-owned dogs and cats with a documented history of CKD undergoing disease follow-up were enrolled. Each included animal underwent a comprehensive physical examination, clinico-pathological and microbiological analyses of blood and urine, along with molecular detection of the 16S rRNA bacterial gene in blood. Aseptically collected blood and urine were obtained through jugular venipuncture and cystocentesis, respectively. After collection, blood and urine samples underwent bacteriological culture within one hour. In the population enrolled, 2/47 dogs and 1/41 cats presented bacteriemia. Moreover, 8/47 dogs and 6/41 cats presented a positive urine culture. Additionally, in one out of the 47 dogs, the same pathogen was identified from blood and urine samples, with a final diagnosis of urosepsis. No instances of bacteriuria-related bacteriemia were observed in the cat population. In conclusion, this study shows a low prevalence of bacteremia and confirms a high prevalence of bacteriuria in companion animals affected by CKD. Moreover, a low prevalence of bacteriuria-related bacteremia was also found.

Bacteriuria Among Type 2 Diabetes Mellitus Patients Attending Ejisu Government Hospital in the Ashanti Region, Ghana.

Type 2 diabetes mellitus (T2DM) patients are at increased risk of infections, such as malignant otitis externa and rhinocerebral mucormycosis, with the urinary tract being the most affected (for example, emphysematous pyelonephritis commonly caused by Escherichia coli). Hence, this study assessed the prevalence of bacteriuria and antibiogram patterns of bacteria isolates among T2DM patients visiting the Ejisu Government Hospital in the Ashanti Region, Ghana. In this cross-sectional study, 58 patients visiting the hospital for routine healthcare were conveniently recruited after obtaining informed consent. Data on sociodemographic characteristics and medical history were obtained using pretested structured questionnaires. Mid-stream urine was collected for bacteria isolation and identification using standard bacterial culture and biochemical tests. Bacteria cultures ≥ 105 CFU/mL were considered significant bacteriuria. The antibiotic sensitivity patterns of the bacteria isolates were evaluated using the Kirby-Bauer disc diffusion method. Bacteriuria was recorded among 15.5% (9/58) of the patients, mainly those with no previous history (77.8%) and no symptoms (55.6%) of urinary tract infections (UTIs). E. coli (55.6%) and Klebsiella spp. (44.6%) were primarily isolated from the T2DM patients. All the bacteria isolates (E. coli and Klebsiella spp.) demonstrated the highest resistance to co-trimoxazole and tetracycline (55.6%) and a complete susceptibility to amikacin and levofloxacin (100%). However, 60% of the E. coli isolates and 25% of the Klebsiella isolates were multidrug resistant (MDR; resistant to at least one antibiotic agent in three or more antimicrobial categories). The study shows that T2DM patients have bacteria in their urine which are resistant to most common antibiotics, even among those with no history of UTIs; hence, routine bacterial culture and antibiotic sensitivity testing among T2DM patients is recommended for better patient management to reduce the co-morbidities of UTIs.

Prevalence of Bacteriuria, and Characterization of Their Antimicrobial Sensitivity Pattern and Efflux Pumps Activity in Diabetic and Non-diabetic Uti Patients

Rationale: Urinary tract infections (UTI) occur more frequently in patients with type 2 diabetes. In developing countries, impairments in the defense system, metabolic disorder during diabetes, and incomplete bladder emptying all contribute to the pathogenesis of UTI in diabetic patients. This comparative study is undertaken to reveal the prevalence of uropathogens and their antimicrobial resistance patterns, and to assess hematological biomarker in diabetic and non-diabetic UTI patients. Methods: The prevalence of uropathogens were tested in 40 diabetic and 40 non-diabetic UTI patients. The antimicrobial susceptibility pattern of bacterial isolates were assessed by the Kirby-Buer disc-diffusion method. Moreover, the bacterial load, Gram-staining, biochemical and serological assays were performed using appropriate methods. Results: The findings showed that diabetic patients are more likely to UTI compared to non-diabetic patients. In terms of uropathogenic prevalence, 61% Escherichia coli, 34% Klebsiella pneumoniae, 2% Staphylococcus aureus, 2% Pseudomonas aureginosa and 1% others. The antimicrobial resistance profile demonstrated that most of the bacterial isolates were resistant to amoxicillin, ampicillin, erythromycin and methicillin but susceptible to azithromycin, chloramphenicol and ciprofloxacin. Moreover, the drug efflux pumps activity and bacterial burden were significantly high among antimicrobial resistant bacterial isolates. Besides, the C-reactive protein, Erythrocyte sedimentation rate, glycosylated hemoglobin A1C, neutrophils and lymphocytes were significantly high in diabetic UTI patients. Conclusion: This study found E. coli was the most frequent bacteria isolates, and this observation is consistent others. Diabetic UTI patients are more vulnerable with high bacterial burden and systemic inflammation. Bioresearch Commu. 10(1): 1413-1419, 2024 (January)

Bacterial profile and prevalence of urinary tract infections in pregnant women in Latin America: a systematic review and meta-analysis

BackgroundGiven the physiological changes during pregnancy, pregnant women are likely to develop recurrent urinary tract infections (UTIs) and pyelonephritis, which may result in adverse obstetric outcomes, including prematurity and low birth weight preeclampsia. However, data on UTI prevalence and bacterial profile in Latin American pregnant women remain scarce, necessitating the present systematic review to address this issue.MethodsTo identify eligible observational studies published up to September 2022, keywords were systematically searched in Medline/PubMed, Cochrane Library, Embase, Web of Science, and Bireme/Lilacs electronic databases and Google Scholar. The systematic review with meta-analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and the quality of studies was classified according to the Strengthening the Reporting of Observational Studies in Epidemiology guidelines. The meta-analysis employed a random-effects method with double-arcsine transformation in the R software.ResultsDatabase and manual searches identified 253,550 citations published until September 2022. Among the identified citations, 67 met the inclusion criteria and were included in the systematic review, corresponding to a sample of 111,249 pregnant women from nine Latin American countries. Among Latin American pregnant women, the prevalence rates of asymptomatic bacteriuria, lower UTI, and pyelonephritis were estimated at 18.45% (95% confidence interval [CI]: 15.45–21.53), 7.54% (95% CI: 4.76–10.87), and 2.34% (95% CI: 0.68–4.85), respectively. Some regional differences were also detected. Among the included studies, Escherichia coli (70%) was identified as the most frequently isolated bacterial species, followed by Klebsiella sp. (6.8%).ConclusionPregnant women in Latin America exhibit a higher prevalence of bacteriuria, UTI, and pyelonephritis than pregnant women globally. This scenario reinforces the importance of universal screening with urine culture during early prenatal care to ensure improved outcomes. Future investigations should assess the microbial susceptibility profiles of uropathogens isolated from pregnant women in Latin America.Trial registrationThis research was registered at PROSPERO (No. CRD42020212601).

Cystitis: significant associations between pathology, histology, and quantitative bacteriology in sows, a cross-sectional study

BackgroundThe importance of cystitis in pig production is controversial and sparse information is available on its frequency and etiology in sows. The aim of this study was to determine the prevalence of bacteriuria, macroscopical and histological lesions of the urinary bladder in culled sows. Urinary bladders and urine samples were obtained from 176 culled sows at slaughter. The urine samples collected by cystocentesis were analyzed to determine bacterial content and pathological findings, macroscopic as well as microscopic, of the bladder were recorded for each sow.ResultsThe prevalence of bacteriuria, defined by bacterial concentrations ≥ 103 colony forming units per mL of urine, was 34%. Escherichia coli was isolated from 69% of the samples with bacteriuria. Redness of the mucosa was the most frequently observed macroscopic change of the bladder. Intense redness and presence of pus was considered significant pathological changes and occurred in 27% of the urinary bladders. The histopathological examination showed that mononuclear cells were the predominant type of cell infiltration in the bladder mucosa, while neutrophils occurred in very few samples. The criteria for cystitis determined by histopathology were met in 46% of the samples. The criteria were based on presence of hyperemia, edema, and inflammatory cell reaction defined as 40 or more neutrophils or mononuclear cells per high power field. All three indicators of cystitis were significantly associated with each other (p < 0.05) at sow level.ConclusionThis study shows that signs of cystitis are common in culled sows. The prevalence of cystitis was 34% based on bacteriological examination, 27% based on macroscopic examination and 46% based on histological examination. Significant associations were found between the three indicators of cystitis: bacteriuria, pathological and histological lesions of the bladder. Based on macroscopic changes and histopathology of the bladder, the cut-off of ≥ 103 colony forming units per mL of urine seems to be appropriate for assessing urine cultures obtained by cystocentesis.

Prevalence of urinary tract infection among pregnant women in a tertiary care hospital, Karnataka: Retrospective study

Background: Urinary tract infection (UTI) is a prevalent medical complication during pregnancy, affecting approximately 5–10% of all pregnancies. The risk of recurrent bacteriuria and acute pyelonephritis is heightened during pregnancy, posing significant risks to both mother and fetus. The prevalence of bacteriuria varies across different regions globally. Due to the physiological changes during pregnancy, clinical diagnosis of UTI can be challenging as it is often mistaken for regular pregnancy-related changes. This research aims to determine the prevalence of symptomatic UTI in pregnant women, analyze the bacteriological profile and antibiotic resistance, and identify the associated risk factors. Materials and methods: This cross-sectional retrospective study was conducted at the Kasturba Hospital from January 2017 to December 2021. Patient information was obtained from the medical records. Data analysis was carried out using Jamovi 2.3.26. The level of significance was set at 5% throughout the study. Results: The study included a total of 256 pregnant women, out of which 38 patients exhibited notable bacterial growth, resulting in an overall prevalence of 1.94%. Among the pregnant women, 84% presented with symptomatic bacteriuria. Conclusion: UTI during pregnancy has significant implications for the health of both the mother and the baby. Our findings indicate an incidence rate of 1.94% for UTI in pregnant women. Among the isolated organisms, Escherichia coli was the most commonly identified, with a higher prevalence rate observed in the third trimester of pregnancy. Pregnant women who develop UTI are at an elevated risk of experiencing adverse maternal and fetal outcomes.

Prevalence of Bacterial Urinary Tract Infection, Associated Risk Factors, and Antimicrobial Resistance Pattern in Addis Ababa, Ethiopia: A Cross-Sectional Study.

Urinary tract infections (UTIs) brought a significant and serious health-related problem that may lead to the subsequent development of serious indications with the challenge of the emergence of antibiotic resistance. Therefore, the choice of antibiotics depends on the accuracy of the diagnostic tool of UTIs to minimize false results that may subject patients to wrong treatments. This study aimed to determine the prevalence of bacteriuria, associated factors, and AMR pattern of UTI-suspected patients. A cross-sectional study was conducted from March to May 2022, at Arsho Advanced Medical Laboratory (AAML), Addis Ababa, Ethiopia. Species identification and isolation from bacterial colonies were characterized by gram stain and biochemical properties followed by antibiotic susceptibility testing using the Kirby-Bauer method on Muller-Hinton agar. Logistic regression analysis was carried out to determine the association between the independent variables and significant bacterial growth to identify factors that affect the prevalence of UTI. A test is considered statistically significant that has a P value less than 0.05. Out of 141 (31.6%) which yielded significant bacteriuria, 16 different species of bacterial uropathogens were identified. A total of 105/446 (91 Gram-negative and 14 Gram-positive) of bacterial growth in the female gender and 36/446 (33 Gram-negative and 3 Gram positive) in male were observed with a P value of 0.03. The most predominant bacteria were E. coli followed by Klebsiella pneumoniae. Amoxicillin had shown the highest resistance rate (100%) followed by Ampicillin (98.9%). Females and participants with previous infections were shown to be associated with significant bacterial growth. Based on our study finding, the ordinarily used antibiotics seem to face emerging resistant strains, which needs considerable and due attention to the impact of UTI in developing countries including Ethiopia. History of previous UTIs and female gender were shown to be possible risk factors associated with UTIs.

Asymptomatic Bacteriuria and Antibiogram of Isolates Among Diabetic Patients in Calabar, Nigeria

Asymptomatic bacteriuria is the presence of bacteria in the urine of an individual without any symptom of urinary tract infection. This has been widely observed in diabetic patients and could be detrimental to their health if not effectively managed. This study was to identify the pathogens associated with asymptomatic bacteriuria among patients with diabetes and the antibiogram of those isolates in Calabar. Blood samples were collected for the determination of fasting blood sugar levels using glucometer. Bacterial isolations were done through urine culture and antibiogram were tested in all urine samples of the diabetic patients in this study. The prevalence of bacteriuria in this study was 26.0%. Participants aged, 41-50 years were highest both in blood sugar level (12.3+/-4.38mmol/L) and infection rate (37.5%, 18/48). Females had lower blood sugar (10.9+/-3.370mmol/L) than the males (11.3+/-4.46mmol/L) while the males had less infection rate (22.4%, 22/98) than the females (29.4%, 30/102). Escherichia coli, 46.2% (24/52) had the highest distribution while Proteus spp. 11.5% (6/52) had the least distribution. Ciprofloxacin was the most sensitivity (100%) while Amoxicillin was the most resistant (38%). There was a high prevalence of asymptomatic bacteriuria in this study. The most commonly observed organisms were Escherichia coli. Ciprofloxacin was the most sensitive antibiotics and there was a widespread antibiotic resistance in this study. It is therefore recommended that screening among diabetic patients for urinary tract infections, sensitization and strategies to promote effective drug usage be encouraged.

Bacteriological pattern of urinary tract infection in men with symptomatic benign prostatic hyperplasia at a tertiary hospital in Nigeria

Introduction/Background: Benign Prostatic Hyperplasia (BPH) is characterized by narrowing of the prostatic urethra with resultant difficulty in passing urine, stasis, and a predisposition to urinary tract infection. The objective of this study is to identify the prevalence of urinary tract infections, common organisms isolated, their antimicrobial sensitivity pattern, and the relationship of co-morbidities with urinary tract infection in this population. Materials and methods: All patients who presented to our urology team with bladder outlet obstruction secondary to benign prostatic hyperplasia between January 2020 and January 2021 were included. Information on age, occupation, co-morbid conditions, urine microscopy, culture, and sensitivity patterns were obtained and analyzed using SPSS version 25. Midstream urine samples were collected from 172 BPH patients. Microscopy, culture, and antibiotic susceptibility tests were carried out. Results: From our study, the prevalence of bacteriuria was 67.9% with the 65-74 and 45-54 age groups having the highest and the least prevalence of bacteriuria (88.9% and 33.3% respectively). The most common organisms cultured from their urine were Pseudomonas (17.9%), E. coli (14.3%), Coliforms (10.7%), and Klebsiella (10.7%). Sensitivity patterns of these microorganisms revealed the highest sensitivity to the fluoroquinolones (25.9%) followed by Nitrofurantoin (14.8%) and Ceftriaxone and Cefoxitin (7.4%). The least sensitivity was to Augmentin and Gentamycin. Conclusion: Bacteriuria is common in patients with BPH. Pseudomonas spp was the commonest isolated organism in our study and most isolated organisms were susceptible to the fluoroquinolones.

Prevalence of bacteriuria in cats with neurogenic bladder

Urinary tract infections are defined as the adherence, multiplication, and persistence of an infectious agent within the urogenital system, causing an associated inflammatory response and clinical signs; instead, the presence of bacteria in urine as determined by positive bacterial culture (PUC) from a properly collected urine specimen, in the absence of clinical signs, is defined subclinical bacteriuria. Limited information on the prevalence of PUC in spinal cord injury cats affected by neurogenic bladder (NB) is available. On contrary, in NB dogs and humans the prevalence of bacteriuria is well documented. Moreover, whilein humans information about bacteriemia associated with NB is already available, this aspect has never been studied in NB cats. The aim of this prospective study was to determine the prevalence of PUC in cats with NB, compared toanimals affected by chronic kidney disease (CKD) and healthy cats. Furthermore, the prevalence of bacteriemia in cats with NB was evaluated. Fifty-one cats met the inclusion criteria: 12 cats were affected by NB, 22 had CKD and 17 were healthy. The prevalence of PUC was 58.33% and 18% in NB and CKD cat populations, respectively. All blood cultures were negative. The incomplete bladder emptying and the decreased resistance in the bladder wall could be considered predisposing elements to PUC in the NB feline population. The results of this study highlight, for the first time, an high prevalence of PUC in cats affected by NB, which was not found to be associated with bacteriemia.

ANTIBIOTIC SUSPECTIBILITY OF URINARY TRACT INFECTION IN LABOUR WARD AT GOVERNMENT MEDICAL COLLEGE HOSPITAL NAGAPATTINAM, TAMIL NADU

Urinary tract infections (UTIs) are the most common infections after respiratory tract infections. UTIs are frequent during pregnancy, affecting as many as 8% of pregnant women. The presence of discernible bacteria in the urine is known as bacteriuria. The overall prevalence of bacteriuria in pregnancy is estimated to be 4–7%. Most importantly, UTI in pregnancy is mainly related to poor hygiene and the low socio-economic status of developing countries. A total of 38 urine samples were collected for the study. The samples were collected from the patients within the period of 01/10/2020–31/09/2021 at the Government medical College hospital, Nagapattinam, Tamil Nadu. For this study, pregnancy cases were taken. Escherichia coli is the common cause of UTI and is responsible for about 70-80% of acute infections in the general population and 50% of hospital-acquired infections. Gram-negative bacteria (78.9%) including E. coli, Pseudomonas, and Klebsiella species were identied. Gram-positive bacteria (21.0%), staphylococcus and streptococcus were identied. Antimicrobial resistance is one of the considerable causes of treatment failure for UTI. Antibiotic resistance highlights the need for stronger action and the adoption of rules that limit the use of antibiotics.

Catheter-associated urinary tract infections in adult intensive care units at a selected tertiary hospital, Addis Ababa, Ethiopia.

BackgroundCatheter-associated urinary tract infection is the leading cause of hospital-acquired infections. They remain the second most common healthcare-associated infection in critically sick patients.ObjectiveTo determine the prevalence of catheter-associated urinary tract infection, the spectrum of etiological agents, antibiotic sensitivity profile of bacterial pathogens among adult patients admitted to intensive care units.Materials and methodsPatients admitted to the intensive care unit of hospitals in Addis Ababa who were on urethral indwelling catheters for >48 hours from October 2020 to September 2021 were included in the study. Urine specimens were aseptically collected and processed as per standard protocols. Microorganisms were isolated, identified, and subjected to antibiotic susceptibility testing.ResultsIn all 220 pateints included in the study development of significant bacteriuria/candiduria was not affected by sex, age, and prior antibiotic therapy. However, the length of stay in the intensive care unit was significantly associated with bacteriuria /candiduria (P-value < 0.001). The overall prevalence of bacteriuria/candiduria was 51.4% among which 21.0%, 19.1%, and 11.4% were bacteriuria, candiduria, and polymicrobial infections, respectively. About 138 organisms were recovered of which 79 (57.25%) were bacteria and 59 (42.75%) were yeast isolates. Acinetobacter species, Pseudomonas species, Klebsiella species E. coli, and Enterococcus species were the dominant bacterial isolates. Candida. albicans, Candida. krusei and Candida. tropicalis were the commonest yeasts. Many gram-negative bacterial isolates were resistant to ceftriaxone 36(94.7%), ampicillin 21(91.3%) followed by cefotaxime34(89.5%), amikacin (16.0%), nitrofurantoin (17.4%), meropenem (20.0%) and imipenem (20.0%). Out of 79 bacterial pathogens, 52(65.8%) were multiple antibiotic resistant of which 37(71.0%) were Gram-negative bacteria and 15(29%%) were Gram-positive bacteria. About 13(86.7%) isolates of Acinetobacter, all isolates of Klebsiella species (100%) and E. coli (100%) were multiple antibiotic-resistant. Out Of 18,10(55.56%), isolates of Enterococcus were multiple antibiotic-resistant.ConclusionsA very high prevalence of bacteriuria/ candiduria was demonstrated in this study. This warrants the establishment of multidimensional infection control approach on catheter associated urinary tract infection in ICU. In addition to high prevalence of candiduria, recovery of non-albicans candida species almost in equal proportion with candida albicans in the present study was an important finding as non-albicans candida species distinct to C. albicans are intrinsically resistant to the commonly used azole antifungal drugs in Ethiopia. The prevalence of rate MDR bacteria in our ICU particularly of E. coli, Klebsiella spp, Pseudomonas and Acetobacter spp was very high. In order to combat this problem, proper antibiotic policies should be formulated.

Prevalence of Bacteriuria in Pregnant Women Visiting Provincial Hospital, Janakpurdham, Nepal

INTRODUCTION: Considering the importance of urinary tract infection (UTI) in pregnant women which is responsible for several complications, its diagnosis and treatment are essential to maintain the health of mother and baby.The purpose of the present study was to evaluate the isolation and identification of Escherichia coli from the UTI suspected pregnant women visiting at provincial Hospital Janakpur.&#x0D; MATERIALS AND METHODS: A total of 200 mid-stream urine samples were collected from UTI suspected pregnant women of 18 to 45 years visiting antenetal OPD in Provincial Hospital Janakpur in between February 2021 to April 2021. The collected urine samples were processed in the microbiology department of the Model Multiple College, Janakpur. Standard Microbiological procedures were followed.&#x0D; RESULTS: The Escherichia coli were predominant identified as 17 (35.41%). Patients aged between 25-30 years were mostly infected 35 (72.9%). The majority of bacteria isolated were more sensitive to Cephalexin and nitrofurantoin.&#x0D; CONCLUSIONS: Escherichia coli is one of the most important pathogen for UTI in pregnant women. The majority of bacteria isolated in the present study were more sensitive to Cephalexin and nitrofurantoin.

Prospective assessment of catheter-associated bacteriuria clinical presentation, epidemiology, and colonization dynamics in nursing home residents

BACKGROUNDCatheterization facilitates continuous bacteriuria, for which the clinical significance remains unclear. This study aimed to determine the clinical presentation, epidemiology, and dynamics of bacteriuria in a cohort of long-term catheterized nursing home residents.METHODSProspective urine culture, urinalysis, chart review, and assessment of signs and symptoms of infection were performed weekly for 19 study participants over 7 months. All bacteria ≥ 1 × 103 cfu/mL were cultured, isolated, identified, and tested for susceptibility to select antimicrobials.RESULTSIn total, 226 of the 234 urine samples were polymicrobial (97%), with an average of 4.7 isolates per weekly specimen. A total of 228 urine samples (97%) exhibited ≥ 1 × 106 CFU/mL, 220 (94%) exhibited abnormal urinalysis, 126 (54%) were associated with at least 1 possible sign or symptom of infection, and 82 (35%) would potentially meet a standardized definition of catheter-associated urinary tract infection (CAUTI), but only 3 had a caregiver diagnosis of CAUTI. Bacterial isolates (286; 30%) were resistant to a tested antimicrobial agent, and bacteriuria composition was remarkably stable despite a combined total of 54 catheter changes and 23 weeks of antimicrobial use.CONCLUSIONBacteriuria composition was largely polymicrobial, including persistent colonization by organisms previously considered to be urine culture contaminants. Neither antimicrobial use nor catheter changes sterilized the urine, at most resulting in transient reductions in bacterial burden followed by new acquisition of resistant isolates. Thus, this patient population exhibits a high prevalence of bacteriuria coupled with potential indicators of infection, necessitating further exploration to identify sensitive markers of true infection.FUNDINGThis work was supported by the NIH (R00 DK105205, R01 DK123158, UL1 TR001412).

Experiences of veterans with spinal cord injury related to annual urine screening and antibiotic use for urinary tract infections.

Antimicrobial-resistant bacterial infections are an increasing public health threat and people with spinal cord injury (SCI) are disproportionally at higher risk. National guidelines concerning urine testing after SCI are conflicting. Unnecessary urine testing in the SCI population (with high asymptomatic bacteriuria prevalence) leads to unnecessary antimicrobial use, propagating resistant infections, especially urinary tract infections (UTIs). (a) Describe UTI antimicrobial adherence in patients with SCI. (b) Explore SCI patient knowledge and attitudes toward current urine testing and treatment practices. Mixed methods. Veterans Health Administration (VHA) patients with SCI. Veterans identified as having SCI seen at a VHA facility nationwide. N/A. Self-reported medication adherence, patient beliefs and behaviors toward UTIs and antimicrobial use. A total of 105 Morisky Medication Adherence Scale-8 (MMAS-8) surveys were completed out of 369 distributed surveys (28% response rate). Overall, patients reported high medication adherence (mean score of 7.2/8, with 8 being a perfect adherence score). Ten qualitative interviews were completed. Themes identified include generally high adherence to prescribed antimicrobial courses and high levels of patient satisfaction with current outpatient VHA SCI bladder care. The quantitative findings converge with these themes observed in the qualitative interviews; patients were satisfied with current urine testing and treatment practices. Veterans with SCI are generally satisfied with their current UTI management and self-report taking antimicrobials for UTIs as prescribed. Veterans with SCI typically report high trust in their SCI providers and value their advice on bladder care management. Therefore, it is imperative for clinicians to provide evidence-based education to patients, as well as ensure that each prescribed course of antibiotics for UTI is clinically necessary. Information from this study will guide an intervention promoting appropriate urine testing and antimicrobial prescription practices by SCI providers.

The Prevalence of Bacteruria and Its Relationship With ABO Blood Group in Pregnant Women

Aims: Blood Group Antigens (ABO) are present on the surface of all cells, including urinary tract cells. Besides, they are a predisposing factor for infection in various parts of the body. The present study aimed to determine the prevalence of bacteriuria and its relationship with different blood groups. Methods &amp; Materials: This descriptive-analytical (cross-sectional) study was performed in 2019 on 400 pregnant women who were selected by convenience sampling method. For each pregnant woman referring to Allameh Behlool Hospital in Gonabad City, Iran, a form including patients’ demographic characteristics, medical history, and blood type was completed. Data analysis was performed in SPSS using descriptive statistics and the Chi-squared test. The significance level of the tests was considered P&lt;0.05. Findings: Of the explored 400 pregnant women with a Mean±SD age of 27.31±5.9 years, 58 were bacterially positive. There was a significant relationship between bacteriuria and ABO blood groups (P=0.001). The examined pregnant women with blood groups O (48.3) and B (29.3) were at higher risk of bacteriuria. There was a significant relationship between bacteriuria and gestational age (P=0.016); accordingly, 56.9% of the study subjects with bacteriuria were in the third trimester. There was no significant relationship between bacteriuria and educational level (P=0.944), and place of residence (P=0.494). Conclusion: The prevalence of bacteriuria among referred pregnant women was measured to be 14.5%. Moreover, pregnant women in the third trimester of pregnancy with blood types O and B were at higher risks for bacteriuria. Therefore, considerations, such as advising this group about the susceptibility to bacteriuria and urinary tract infections, personal hygiene, and faster referral for diagnostic and therapeutic measures if presenting symptoms, as well as informing doctors and obstetricians about this condition and help to make faster decisions are recommended in this respect.

Urinary Bacterial Profile and Antibiotic Susceptibility in Pregnant Adolescents and Pregnant Low Obstetric Risk Adult Women.

IntroductionSignificant bacteriuria is associated with clinical and obstetric complications. The existing studies on the profile of urinary pathogens in pregnant women have widely divergent results and they hardly include data on pregnant adolescents.MethodsThis observational retrospective study was conducted in a tertiary hospital in the city of São Paulo with 388 pregnant adolescents and 2547 pregnant low-risk obstetric care adults who began prenatal care between January 2010 and January 2016. They were compared in terms of urine sediment, urine culture, and antibiogram results.ResultsThe prevalence of bacteriuria was 17.01% (66/388) among adolescents and 10.13% (258/2547) among adults. Adolescence was a risk factor for bacteriuria in pregnancy (OR=1.82, CI95%=1.35–2.44, p=0.08). The most frequently isolated pathogen in urine culture was Escherichia coli, both in adolescents (49%) and in adults (42.18%). In positive urine cultures, urinary leukocytes were present in greater numbers in adolescents than in adults (p<0.001). Resistance to quinolones in general was more frequent among adults (OR=5.86, CI95%=0.78–44.20, p<0.001), but the tendency was not statistically significant.ConclusionEscherichia coli and the less frequent Streptococcus agalactiae were the etiologic agents most often found in the urine cultures both of adolescents and adults. Higher rates of bacteriuria and of abnormal urine sediments prevailed among adolescents.
