Antibody response after feline panleukopenia virus vaccination in kittens with and without intestinal parasites.

Vaccinations should only be given to healthy cats, and deworming before vaccination is generally recommended; however, so far, no study has investigated the influence of intestinal parasitic infection on the immune response in kittens. The aim of this prospective study was to compare the antibody response to feline panleukopenia virus (FPV) vaccination in kittens with and without intestinal parasites. Overall, 74 healthy kittens were included. Of these, 17 had intestinal parasites (12/17 Toxocara cati, 6/17 Cystoisospora felis, 1/17 Capillaria species). Both kittens with and without (n = 57) parasites received two primary kitten vaccinations with modified live FPV vaccines in a 4-week interval starting at the age of 8-12 weeks. Anti-FPV antibodies were determined at the beginning of the study (week 0) and at week 8 (4 weeks after the second vaccination) by haemagglutination inhibition. A ⩾four-fold titre increase (week 8 vs week 0) was defined as a response to vaccination. Comparison of the immune response in the kittens with and without intestinal parasites was performed using Pearson's χ2 test. Pre-vaccination antibodies were present in 4/17 (23.5%) kittens with intestinal parasites and in 24/57 (42.1%) without parasites. A ⩾four-fold titre increase was seen in 13/17 (76.5%) kittens with parasites compared with 32/57 (56.1%) kittens without parasites. There was neither a significant difference in pre-vaccination antibodies (P = 0.17), nor in vaccination response (P = 0.13) between kittens with and without parasites. The results indicate that asymptomatic intestinal infections with endoparasites do not interfere with the immune response to kitten vaccination series. Parasitic infection (at least with T cati, C felis and Capillaria species) is therefore not a reason to postpone important vaccinations.

Pattern of intestinal parasitic infections in children with malnutrition in Somalia

ObjectivesChildren living in conflict zones plagued with adverse climatic conditions often suffer from acute malnutrition. Being coinfected with intestinal parasites could worsen the prognosis if adequate interventions are not promptly instituted. We determined the pattern of intestinal parasitic infections (IPIs) in children with acute malnutrition in the Bay and Banadir regions of Somalia. MethodsA hospital-based cross-sectional study was conducted from August to October 2023 in 222 children with acute malnutrition aged 6-59 months, using a structured questionnaire and stool examination by a trained laboratorian. The prevalence of IPI was estimated and the pattern of IPI was explored. The relationship between the presence of IPI and demographic characteristics was examined with multiple logistic regression at a 95% level of confidence. ResultsThe mean age was 20.4 ± 12.3 months, 125 (56.3%) were females, and 41.9% were internally displaced. The prevalence of IPI was 82.9% (95% confidence interval: 77.4-87.3), Of the infected, 73.9% (136 of 184) had single parasitic infection and 23.4% (43 of 184) had double parasitic infections. Ascaris lumbricoides (46.6%), Giardia lamblia (22.1%), and Entamoeba histolytica (17.6%) were the most common parasites identified. The age of 13-36 months (adjusted odds ratio: 1.13, P = 0.02) and eating once a day (adjusted odds ratio: 1.13, P = 0.06) were associated with being infected with intestinal parasites. ConclusionsThe prevalence of intestinal parasitic infection was high in children with malnutrition in the Bay and Banadir regions. Deworming should be extended to all children with malnutrition. Food, sanitation, and water provision initiatives should be improved at the community level.

Presence of Intestinal Parasites in Patients with Chronic Non-Communicable Diseases in Masaya (Nicaragua).

A cross-sectional study was conducted in Masaya (Nicaragua) to estimate the prevalence of intestinal parasite (IP) infections in patients with non-communicable diseases (NCDs) and to determine the associations between the types of NCDs and patients' epidemiological characteristics of infection. A total of 157 preserved faecal samples were examined (direct wet mount, formalin/ethyl acetate concentration and modified Ziehl-Neelsen technique). Microscopically positive faecal sample identification was completed by conducting a molecular study. The total prevalence of IP was 52% in NCD patients. Diabetic patients presented an IP prevalence of 42%. Blastocystis presented the highest prevalence (42%). A molecular analysis of Giardia intestinalis (prevalence of 1.3%) revealed 100% of sub-assemblage BIII and the Entamoeba complex (5%) was identified as E. dispar. Blastocystis ST1 appeared in 44% of those suffering from diabetes and ST3 in 66% of those suffering from hypertension, while ST2 only appeared in those suffering with several NCDs simultaneously. In diabetic patients, the risk of infection is associated with having pets (p = 0.021) and land-floor houses. The risk of infection appears to be statistically related (p = 0.019) in those with several NCDs having received a previous helminthic deworming treatment. Coordinated public health activities for IP and NCD screening and diagnosis are crucial to their successful control programmes.

A cross-sectional study on the prevalence and associated risk factors for intestinal parasitic infections among under-five aged children in Dabat primary hospital, north Gondar, Ethiopia.

Intestinal parasitic infections (IPIs) are the main public health problems in several developing countries, and under-five-aged children are the most vulnerable groups of the population. The current study aimed to determine the prevalence and associated risk factors of IPIs among under-five-aged children at Dabat primary hospital, northwest Ethiopia. A cross-sectional hospital-based study including 384 under-five-aged children was conducted from February to June 2022. A structured questionnaire was used to collect relevant information on risk factors, and stool samples were collected and examined using wet mount and sedimentation techniques to determine prevalence. Chi-square and logistic regression were used to evaluate the possible association and the strength of the association between dependent and independent variables. The overall prevalence of intestinal parasites was 32.81%. Ten species of intestinal parasites were identified. Entamoeba histolytica / dispar was the predominant intestinal parasite species, with a prevalence of 7.55%. Giardia lamblia and hookworm had prevalence of 6.77% and 5.47% respectively. Those children whose Mother/guardian do not wash their hand before feeding their child are more than five time infected than those who do wash (AOR = 5.26, CI = 2.28-12.2, p < 0.001). Children who do not wear shoe are more infected than who did (AOR = 14.5, CI = 5.77-36.5, p < 0.001). Several risk factors were identified in this study among these washing hands after toilet before touching child, washing hands before feeding their child, Child meal and habit of shoes wearing were the main predictors of IPI. Since the prevalence of IPI observed in this study is that of under-five-aged children; raising awareness of mothers/guardians about how to keep hygiene; transmission ways and health impacts of IPIs; and proper way of feeding their children to avoid risk is crucial.

Modulation of the intestinal mucosal and cell-mediated response against natural helminth infection in the African catfish Clarias gariepinus

Fish gut is a versatile organ serving as the primary pathway for invasion by pathogens, particularly parasites, playing a crucial role in modulating the intestinal adaptive immune response. This study aimed to investigate the cellular-mediated reaction, mucosal acidity, and the expression of proliferating cell nuclear antigen (PCNA), vascular endothelial growth factor (VEGF), and CD68 in the intestines of catfish, Clarias gariepinus, naturally infected with helminths. Forty catfish were collected from the Nile River and examined for intestinal parasites. The intestinal tissues of the control and infected fish were fixed for histochemical and immunohistochemical studies. Two groups of helminths were found: cestodes Tetracampos ciliotheca and Polyonchobothrium clarias, and nematodes Paracamallanus cyathopharynx, with a prevalence rate of 63.63%, 18.0%, and 18.0%, respectively. Our results showed that the infected fish had a statistically significant rise in the activity of immune cells, including mast cells, eosinophil granular cells, and dendritic cells. This correlated with upregulation in the expressions of PCNA, VEGF, and CD68. Histochemical analyses demonstrated a marked increase in acidic mucus production, Sudan black B, and bromophenol mercury blue. This study enriches our understanding of the evolution of vertebrate immunity in combating intestinal parasitic infections and the host’s adaptive responses.

Gut microbiota metabolically mediate intestinal helminth infection in Zebrafish.

Intestinal helminth parasite (IHP) infection induces alterations in the composition of microbial communities across vertebrates, although how gut microbiota may facilitate or hinder parasite infection remains poorly defined. In this work we utilized a zebrafish model to investigate the relationship between gut microbiota, gut metabolites, and IHP infection. We found that extreme disparity in zebrafish parasite infection burden is linked to the composition of the gut microbiome, and that changes in the gut microbiome are associated with variation in a class of endogenously-produced signaling compounds, N-acylethanolamines, that are known to be involved in parasite infection. Using a statistical mediation analysis, we uncovered a set of gut microbes whose relative abundance explains the association between gut metabolites and infection outcomes. Experimental investigation of one of the compounds in this analysis reveals salicylaldehyde, which is putatively produced by the gut microbe Pelomonas, as a potent anthelmintic with activity against Pseudocapillaria tomentosa egg hatching, both in vitro and in vivo. Collectively, our findings underscore the importance of the gut microbiome as a mediating agent in parasitic infection and highlights specific gut metabolites as tools for the advancement of novel therapeutic interventions against IHP infection.

Evaluating Malnutrition Practices and Mother's Education on Children Failure to Thrive Symptoms Using Entropy-Weight and TOPSIS Method.

Failure to thrive (FTT) is mostly caused by insufficient consumption of nutrient-rich food, recurrent infections like diarrhea and intestinal worms, substandard caregiving practices, and limited availability of health and other vital services. Furthermore, there was a correlation between the educational level of mothers and the occurrence of FTT in children aged 6-12 months. Thus, the objective of the current research is twofold: (i) to investigate other factors related to FTT and (ii) to evaluate the impact of them on FTT in Sub-Saharan African countries and their urban areas. We used weight entropy and TOPSIS methods to approach the research question. In particular, the entropy-weight method is effective for precisely evaluating the relative significance of the selected criteria for TOPSIS computation. Thus, data were retrieved from the database of UNICEF for the year 2019 for nine Sub-Saharan countries, and based on the methods used, five criteria have been selected for consideration. Those of mothers in higher education were identified as having a higher weight, which means that this can affect positively the ability of mothers to mitigate the situation of FTT and protect their children. The findings of the study highlight the factors of maternal education at a higher level and unhealthy habits as those with the greatest weight and impact on the FTT. Moreover, the results indicate that the association between maternal education, and especially higher education, and FTT is stronger in Ethiopia. Despite the limited amount of research on the specified relationship in Sub-Saharan countries, this study is among the initial ones to examine it. The current study can aid policymakers in devising appropriate policies and implementing effective measures to tackle FTT in Sub-Saharan Africa, like enhancing the number of mothers in these countries to be integrated into the educational system to help both themselves and their children mitigate or avoid the symptoms of FTT.

Prevalence of intestinal parasites in humans and domestic animals in Jirel community, Dolakha, Nepal.

Gastrointestinal (GI) parasites are major health concerns in both humans and domestic animals. Livestock farming is one of the common livelihood practices in rural Nepal. The proximity at human and domestic animal interface increases the chances of dissemination of enteric parasites, especially those of zoonotic importance. This study was aimed at finding the parasite prevalence and risk factors in both humans and their domestic animals in Jirel community. A field survey was conducted on the Jirel ethnic people and their domestic animals in Dolakha district, where a total of 152 fresh fecal samples from humans and domestic animals (cow, pigs, goats, chickens, ducks, and pigeons) were collected. The feces were examined by wet mounts and concentration techniques. A structured questionnaire survey was carried out among the local people and owners of the domestic animals to gather sociodemographic information, awareness, and hygienic practices in relation to parasite transmission. The enteric parasite prevalence was found to be highest in goats (80.0%;12/15), followed by pigs (55.55%;5/9), cows (45.45%;6/11), chickens (11.7%;4/34), and humans (1.41%;1/71), while the fecal samples of ducks and pigeons did not contain any parasites. The only parasite identified in humans was Ascaris lumbricoides. Similarly, three genera of GI parasites (Eimeria sp., Strongyloides sp, and Trichuris sp.) from goats, two genera each from cow (Eimeria sp. and Strongyloides sp.), pigs (Entamoeba sp. and A. suum), and chickens (Eimeria sp. and Ascaridia galli), were detected. Based on the direct field observation, questionnaire survey and laboratory analysis, it is concluded that the Jirel community people are aware of health and hygiene; however, intervention measures are necessary to prevent parasitic infection in their domestic animals.

On the host specificity and genetic diversity of Iodamoeba bütschlii: Observations from short amplicon-based next-generation sequencing

Iodamoeba is a single-celled intestinal parasite, which is common in humans in certain parts of the world, and also in pigs. For the first time, we provide DNA-based evidence of goat, dromedary, fallow deer, and donkey as hosts of Iodamoeba and show that Iodamoeba-specific nucleotide sequences from these four hosts do not appear to overlap with those of humans, unlike those from pigs. We moreover show that similar strains of Iodamoeba can be found in Madagascar, Western Sahara, and Ecuador and that intra-sample diversity is typically extensive across even small fragments of DNA in both human and non-human hosts.

Insights into trophic interactions: DNA metabarcoding reveals species composition in black-tailed gull fecal samples in coastal environments of South Korea.

This study explored the algae, zooplankton, macroinvertebrate, fish, and parasitic single-celled organism communities in Larus crassirostris (black-tailed gull) fecal samples from Baengnyeongdo, Hongdo, and Ulleungdo in South Korea. The fecal samples can identify key species consumed by black-tailed gull, providing insights into their, trophic interactions, and habitat dependencies. Using DNA metabarcoding, we identified algae, zooplankton, macroinvertebrate, fish, and intestinal and single-celled parasite species in the fecal samples. Parasitic single-celled organisms, such as Rhogostoma sp., Rhogostoma schuessleri, Eimeria furonis, and Aggregata eberthi, showed differing relative abundances at each sampling location, indicating variability in parasite diversity in the fecal DNA analysis of birds at each site. Intestinal parasites showed similar site-specific variability, though Clistobothrium sp. and Tetrabothrius sp. were common at all locations. Algae species, including Heterocapsa steinii, Heterocapsa niei, and Sargassum cristaefolium, also displayed habitat-specific patterns, as did zooplankton, with Calanus sp., Corycaeus speciosus, and Caprella californica being dominant on Baengnyeongdo, Hongdo, and Ulleungdo, respectively. In the macroinvertebrate communities, Octopus sinensis was prevalent at all locations but at varying abundances. Site-specific dominant fish species were also identified, with Ammodytes personatus, Decapterus maruadsi, and Arctoscopus japonicus highly predominant on Baengnyeongdo, Hongdo, and Ulleungdo, respectively. Other fish species, such as Ammodytes hexapterus, were detected in lower frequencies, suggesting a diverse diet for the seabirds. These results offer insights into the species composition and ecological dynamics in black-tailed gull populations across disparate Korean islands.

Prevalence of Intestinal Helminthes among School-Aged Children in Ife Central Local Government, Nigeria: Implications for Targeted Interventions

Background: Soil-transmitted helminths (STHs) are a major health concern for children in developing countries. This study assesses the prevalence and intensity of STHs among pupils in private nursery and primary schools in Ile-Ife, Nigeria. Methods: The study was conducted in Ife Central LGA, Osun State, Nigeria, involving preschool and school-aged children from two private schools. A total of 55 samples, from 22 male and 33 female pupils, were analyzed for intestinal parasite ova to determine the prevalence of helminth infections among the children. Ethical approval was obtained from the Institute of Public Health, Obafemi Awolowo University, Ile-Ife. Consent was secured from parents or guardians. Samples were processed using the modified Kato-Katz technique and examined microscopically for soil-transmitted helminth (STH) eggs. Data was analyzed using descriptive statistics and chi-square tests, with significance set at p &lt; 0.05. Results: Among the 55 fecal samples collected, the overall prevalence of soil-transmitted helminth (STH) infections was 78.2%. Ascaris lumbricoides were the most prevalent helminth (76.4%), followed by Trichuris trichiuria (14.5%) and hookworms (5.5%). Females had a higher infection rate (81.8%) than males (68.2%). The prevalence of STH infections was highest among pupils aged ≥10 years (81.8%) and lowest among those aged 2-3 years (66.7%). Conclusion: This study highlights a significant burden of STH infections, particularly A. lumbricoides, among schoolchildren in Ile-Ife, Nigeria. The high prevalence necessitates targeted deworming and improved sanitation interventions to reduce the burden of these infections among children in this region.

Interaction between Intestinal Parasites and the Gut Microbiota: Implications for the Intestinal Immune Response and Host Defence.

Intestinal parasites, including helminths and protozoa, account for a significant portion of the global health burden. The gastrointestinal (GI) tract not only serves as the stage for these parasitic infections but also as the residence for millions of microbes. As the intricacies of the GI microbial milieu continue to unfold, it is becoming increasingly apparent that the interactions between host, parasite, and resident microbes help dictate parasite survival and, ultimately, disease outcomes. Across both clinical and experimental models, intestinal parasites have been shown to impact microbial composition and diversity. Reciprocally, microbes can directly influence parasitic survival, colonization and expulsion. The gut microbiota can also indirectly impact parasites through the influence and manipulation of the host. Studying this host-parasite-microbiota axis may help bring about novel therapeutic strategies for intestinal parasitic infection as well as conditions such as inflammatory bowel disease (IBD). In this review, we explore the relationship between intestinal parasites, with a particular focus on common protozoa and helminths, and the gut microbiota, and how these interactions can influence the host defence and intestinal immune response. We will also explore the impact of this tripartite relationship in a clinical setting and its broader implications for human health.

Molecular detection and identification of Enteromonas species in human and animal hosts using polymerase chain reaction and DNA sequencing

Enteromonas hominis, a human intestinal protozoan parasite of the diplomonad group, has been overlooked because of its commensal features; therefore, molecular studies on this parasite are limited. To address this gap, we designed a molecular screening protocol using polymerase chain reaction (PCR) and DNA sequencing targeting the 18S small subunit ribosomal RNA gene and applied this screening method to the molecular epidemiological analysis of Enteromonas spp. in humans and various livestock. We validated our methodology using stool samples collected from 215 humans and 270 animal hosts (buffaloes, pigs, dogs, goats, horses, rodents, chickens, and ducks) during an annual epidemiological investigation conducted from 2013 to 2016 on Sumba Island, Indonesia. The overall prevalences of Enteromonas spp. were 33.9 % (n = 73/215) in humans and 25.2 % (n = 68/270) in mammals and avians. The positive predictive value of this PCR method for Enteromonas spp., as evaluated through sequencing, was 90.1 % in human samples and 58.1 % in non-human samples (particularly low, 11.4 % in rodents). Although the specificity of the PCR approach may not be perfect, in combination with DNA sequencing, it was effective in detecting and identifying a partial sequence (1458 bp) of the target gene region in Enteromonas species.

Malnutrition and intestinal parasitosis: Current prevalences and risk factors among schoolchildren in Misiones (Argentina).

To assess the current prevalences of nutritional status and intestinal parasites, and their potential association with socio-environmental conditions among schoolchildren in Aristóbulo del Valle, Misiones. We measured body weight and height in 444 schoolchildren aged 3-14 years and evaluated their nutritional status following WHO criteria. We examined fecal samples and anal swabs from 234 schoolchildren and collected socio-environmental data through questionnaires. The prevalence of undernutrition was 4.5% and excess of weight was 24.1%. The prevalence of stunting and of being overweight reached 2.3% and 12.4%, respectively. About 42% of the schoolchildren were infected with at least one of the 12 species identified. The most prevalent species were Blastocystis sp., Enterobius vermicularis, and Giardia lamblia. Entamoeba dispar was recorded for the first time in the locality. The multiple correspondence analysis identified peri-urban, urban, and rural groups. Underweight, stunting and obesity were highest in the peri-urban group, while overweight, wasting and parasitism rates were highest in the rural group. The urban group showed the lowest parasitic prevalences. Bed-sharing, mother's education, and animal husbandry were associated with parasitic infections. The study highlights a decrease in undernutrition but a rise in overweight and obesity, indicating an ongoing nutritional transition. The association between socio-environmental risk factors and parasitic infections underscore the need for comprehensive interventions addressing both nutritional and socio-environmental conditions to improve the population's life quality.

Intestinal parasitic infections in patients with aids in northeast Brazil: an historical series from 2017 to 2022

Opportunistic infections are a major cause of death in patients with acquired immunodeficiency syndrome (AIDS). Intestinal parasitic infections (IPIs) may aggravate the clinical condition of immunosuppressed patients and they may increase the risk of death. The goal of the present study was to determine the epidemiological profile of patients with AIDS and IPIs who visited a reference hospital for contagious diseases in Northeast Brazil from 2017 through 2022. It was an observational, transverse, descriptive, and analytical study. Medical records were assessed, epidemiological questionnaires were administered to identify risk factors for IPI, and coproparasitological examinations were performed to detect IPI. Of the 248 patients included in this study, 30.6% (76/ 248) tested positive for IPI. Entamoeba histolytica/ dispar (16.5%) and Strongyloides stercoralis (14.4%) were the most prevalent protozoa and helminths identified. Diarrheic consistency was observed in 25.8% of the feces samples, and mucus or blood were present in 19.4%. Analysis of the sociodemographic profiles of patients with IPIs showed that most were female, lived in small cities, earned up to two minimum wages, had an incomplete primary education, and were single. We conclude that to control parasite transmission in patients with HIV/AIDS, public policies related to human and environmental health, routine coproparasitological exams, and acceptance of antiretroviral therapy are necessary. KEY WORDS: Acquired immunodeficiency syndrome; opportunistic infections; intestinal parasite infections; public health.

Review of the concentration procedures used to determine the parasitological water quality in Latin America (2000–2022)

ABSTRACT The aim was to review the methodologies used in the concentration of intestinal parasites in different water samples in Latin America. The period of the review was between September and November 2022. Of the total number of articles (N = 87), the search engine with the most articles matching the specified keywords was Google Scholar (56.3% = 49 articles), and Brazil was the country that published the most articles (28.7%). Most of the studies were conducted for surface waters (75.9%) and used methodologies with physical separation without subsequent parasitological concentration (76.9%). However, the ultrafiltration method (UFM) with subsequent parasitological concentration recovered a greater number and type of parasite species. The descriptive study of the review shows that the procedure of using UFM with a parasitological method of flotation and sedimentation would allow an efficient concentration of the parasite species present in the water sample.

Antenatal care utilisation and receipt of its components in Nigeria: Assessing disparities between rural and urban areas-A nationwide population-based study.

Antenatal care (ANC) is crucial for positive pregnancy outcomes, but it is underutilised in Nigeria, suggesting unmet needs, and potentially contributing to the country's high burden of maternal and neonatal mortalities. This study comprehensively assesses ANC utilisation and receipt of its components in Nigeria, focusing on disparities between rural and urban areas. We used the data disaggregation approach to analyse the Nigeria Demographic and Health Survey 2018. We estimated ANC utilisation, assessed the receipt of ANC components, and identified factors associated with eight or more (≥ 8) ANC contacts nationally and across rural and urban residences. Nationwide, only 20.3% of women had ≥ 8 ANC contacts, with a significant disparity (P < 0.001) between urban (35.5%) and rural (10.4%) areas in Nigeria. The North-East region had the lowest ANC utilisation nationally (3.7%) and in urban areas (3.0%), while the North-West had the lowest in rural areas (2.7%). Nationally, 69% of mothers received iron supplements, 70% had tetanus injections, and 16% received medicines for intestinal parasites, with urban residents having higher proportions across all ANC components. Maternal and husband education, health insurance, and maternal autonomy were associated with increased ANC odds at the national, rural, and urban residences. However, differences exist, with all ethnicities having higher ANC odds than the Hausa/Fulanis in urban areas and the Yorubas demonstrating greater odds than other ethnicities in rural settings. Internet use was significant only in the national context, watching television only in urban settings, while maternal working status, wealth, birth type, religion, and radio listenership were significant in rural areas. Our study reveals significant disparities in ANC utilisation and components across Nigeria, with rural residents, particularly in northern regions, as well as socioeconomically disadvantaged and teenage mothers facing notable challenges. A multifaceted approach prioritising the interplay of intersectional factors like geography, socioeconomic status, education, religion, ethnicity, and gender dynamics is essential. Key strategies should include targeted interventions to promote educational opportunities, expand health insurance coverage, leverage internet and context-specific media, and foster socioeconomic empowerment, with priority for underserved populations.

Assessment of bacterial and parasitic contamination of fruits gathered from specific local markets in Addis Ababa, Ethiopia

BackgroundAround the world, food-borne illnesses are still a frequent and significant hazard to public health. Human infection outbreaks brought on by eating raw fruits have happened more frequently. Fruits have been connected in recent years to a number of outbreaks of food-borne illness around the globe, including in Ethiopia.ObjectiveTo assess bacterial and parasitic contamination of fruits gathered from specific local markets in Addis Ababa, Ethiopia.MethodsA cross-sectional study was carried out using fruits gathered from Addis Ababa local marketplaces. Convenient sampling were applied. With the assumption that each vendor provided 30 samples, a total of 120 fruit samples were gathered. Fruit samples were gathered in a plastic bag that had been sanitized and then brought to the lab for bacterial and parasitological investigation. All of the samples were checked for intestinal parasites and bacterial contamination. SPSS software version 25 was used to analyze the data. The Pearson's Chi-square test was used to assess categorical variables. The student's t-test was utilized to compare continuous variables, which were represented as the mean ± standard deviation. Using both univariate and multivariate analysis, odds ratios (OR) with 95% confidence intervals (CI) were computed. Statistical significance was defined as a P &amp;lt; 0.05.ResultsThere was a 100 (83.3%) level of bacterial contamination. While Salmonella and Shigella species were not recovered, S. aureus isolates 16 (13.3%) were the most common bacterial contamination, followed by E. coli isolates 8 (6.7%). The samples of bananas, mangos, papayas, and avocados from all four sites had total coliform (TCC) bacteria ranging from 2.1 × 103 to 3.2 × 104, 8.3x 102 to 1.8x 105CFU/g, 1.6x 102 to 3.7 x 104, and 1.2x 102 to 3.8 x 104 CFU/g, in that order. No parasites were found in this investigation.Conclusion and recommendationIt is usually recommended that customers in this research region wash and handle infected fruits properly to prevent bacterial illnesses. In addition, fruit dealers should have their bacterial contaminations routinely inspected. Large-scale research is advised to support this discovery.
