Consumption Of Unpasteurized Milk Research Articles

Responding to outbreaks of illness linked to unpasteurized milk: A needs assessment of state health and agriculture departments.

Consumption of unpasteurized milk can result in severe illness or death. In the United States, the number of people who regularly consume unpasteurized milk is relatively low, but outbreaks resulting from unpasteurized milk outnumber outbreaks linked to pasteurized milk. The sale of unpasteurized milk for human consumption through interstate commerce is prohibited at the federal level, but laws among states vary considerably with respect to the sale of unpasteurized milk. Each state has a different perspective on responding to and preventing outbreaks of illness linked to consuming unpasteurized milk. We conducted a needs assessment of state health and agriculture departments to gather information on state-level strategies to prevent illnesses linked to consuming unpasteurized milk, characterize challenges states face, and identify areas where partners can support state efforts to prevent illnesses. We deployed a survey from 6 January 2021 to 1 March 2021, using a snowball sampling strategy and had 158 respondents. Of 115 respondents, 46 (40%) believed that state laws were ineffective in preventing illnesses, and 92 (80%) agreed that consumers continue to find ways to get unpasteurized milk despite laws restricting sale. Respondents from 19 states were aware of future legislative or regulatory efforts surrounding unpasteurized milk in their state, with 14 (74%) indicating these efforts would expand consumer access. The most common outbreak prevention strategies respondents mentioned included sharing knowledge and experiences with other public health and agriculture officials, providing information to inform legislative efforts, and communicating to the public about outbreaks. Most respondents (41/50, 91%) were interested in pursuing further efforts to prevent unpasteurized milk-associated illnesses in their state. The results from this needs assessment can be used to inform future strategies for preventing illness outbreaks associated with unpasteurized milk consumption.

Micro- and nanoformulations of antibiotics against Brucella

Brucellosis, a zoonotic intracellular bacterial infection primarily transmitted through the consumption of unpasteurized milk from infected animals, remains a challenging condition to clinically control. This is mainly because of the limited effectiveness of conventional antibiotics in targeting intracellular Brucella. Micro- and nanoformulations of antibiotics, whether used as a mono- or combination therapy, have the potential to reduce the antibiotic doses required and treatment duration. Extensive research has been conducted on various organic, semiorganic, and inorganic nanomaterials with different morphologies, such as nanoparticles (NPs), nanotubes, nanowires, and nanobelts. Metal/metal oxide, lipidic, polymeric, and carbonic NPs have been widely explored to overcome the limitations of traditional formulations. In this review, we discuss the advances and challenges of these novel formulations based on recent investigations.

Isolation and identification of Staphylococcus aureus from bovine milk and community awareness on public health significance of mastitis in and around Jigjiga, Somali region, Ethiopia

A cross-sectional study on lactating cattle was done from December 2019 to July 2020 to identify and isolate Staphylococcus aureus from bovine mastitic milk and assess community awareness of public health problems connected with mastitis in and around Jigjiga. Among 353 milk samples, 96 were determined to be mastitis positive. Clinical and subclinical mastitis were found in 79 and 17 respectively. Milk samples (n = 96) from clinical and subclinical animals were cultured to isolate S. aureus; S. aureus isolates were detected in 51.04 % (49/96) of the samples. The study was also conducted to investigate community awareness of the public health significance of mastitis and 89 % of people were aware of the disease's existence, particularly the clinical form of mastitis, due to its prominent clinical signs. In contrast, 80 % of them were unaware of the subclinical form of mastitis. About 78 % of those questioned said they had no idea mastitis could be passed from cow to cow. The majority of participants (65 %) stated that they consumed raw milk. The large percentages of respondents (92 %) were unaware that enterotoxigenic S. aureus can be found in mastitic milk. This study suggests that the most of the communities in the study site was unaware of the disease's effects. Therefore, community awareness about the public health importance of mastitis and hazardous of microbial in milk, particularly S. aureus, which causes food contamination and serves as a method of disease transmission to people through unpasteurized milk consumption, should be implemented.

Tick-Borne Encephalitis-Review of the Current Status.

The tick-borne encephalitis virus (TBEV) is the arboviral etiological agent of tick-borne encephalitis (TBE), considered to be one of the most important tick-borne viral diseases in Europe and Asia. In recent years, an increase in the incidence of TBE as well as an increasing geographical range of the disease have been noted. Despite the COVID-19 pandemic and the imposition of restrictions that it necessitated, the incidence of TBE is rising in more than half of the European countries analyzed in recent studies. The virus is transmitted between ticks, animals, and humans. It seems that ticks and small mammals play a role in maintaining TBEV in nature. The disease can also affect dogs, horses, cattle, and small ruminants. Humans are incidental hosts, infected through the bite of an infected tick or by the alimentary route, through the consumption of unpasteurized milk or milk products from TBEV-infected animals. TBEV infections in humans may be asymptomatic, but the symptoms can range from mild flu-like to severe neurological. In Europe, cases of TBE are reported every year. While there is currently no effective treatment for TBE, immunization and protection against tick bites are critical in preventing this disease.

Tick-Borne Encephalitis in a 6-Year-Old Patient: A Case Report.

Background: Tick-Borne Encephalitis virus (TBEV) is a positive-sense single-stranded RNA virus belonging to the Flaviviridae family. TBEV transmission typically occurs through infected Ixodes tick bite or by consumption of unpasteurised milk from infected cattle. Case report: We report the clinical, neuroimaging, electroencephalogram (EEG), and laboratory (microbiological tests and spinal tap) data of a 6- year-old boy with Tick-borne encephalitis. Our patient presented with a biphasic course, initially with a myositis-like picture on his first admission to the emergency department, and after a few days with an encephalitic picture, resulting in a second hospitalization. EEG showed focal slow activity, while his brain magnetic resonance imaging (MRI) showed a signal abnormality, which completely resolved on repeat MRI after 3 months. Conclusion: To our knowledge, this is the youngest patient presenting with myositis in the first phase of Tick-borne encephalitis (TBE). In the presence of a biphasic clinical course, with previous myositis, aspecific MRI changes in the thalamic and midbrain regions and an EEG documenting slowed bioelectrical activity should prompt suspicion of TBEV infection.

Genome engineering of Stx1-and Stx2-converting bacteriophages unveils the virulence of the dairy isolate Escherichia coli O174:H2 strain UC4224.

The past decade witnessed the emergence in Shiga toxin-producing Escherichia coli (STEC) infections linked to the consumption of unpasteurized milk and raw milk cheese. The virulence of STEC is primarily attributed to the presence of Shiga toxin genes (stx1 and stx2) carried by Stx-converting bacteriophages, along with the intimin gene eae. Most of the available information pertains to the "Top 7" serotypes associated with STEC infections. The objectives of this study were to characterize and investigate the pathogenicity potential of E. coli UC4224, a STEC O174:H2 strain isolated from semi-hard raw milk cheese and to develop surrogate strains with reduced virulence for use in food-related studies. Complete genome sequence analysis of E. coli UC4224 unveiled the presence of a Stx1a bacteriophage, a Stx2a bacteriophage, the Locus of Adhesion and Autoaggregation (LAA) pathogenicity island, plasmid-encoded virulence genes, and other colonization facilitators. In the Galleria mellonella animal model, E. coli UC4224 demonstrated high pathogenicity potential with an LD50 of 6 CFU/10 μL. Upon engineering E. coli UC4224 to generate single and double mutant derivatives by inactivating stx1a and/or stx2a genes, the LD50 increased by approximately 1 Log-dose in the single mutants and 2 Log-doses in the double mutants. However, infectivity was not completely abolished, suggesting the involvement of other virulence factors contributing to the pathogenicity of STEC O174:H2. Considering the possibility of raw milk cheese serving as a reservoir for STEC, cheesemaking model was developed to evaluate the survival of UC4224 and the adequacy of the respective mutants as reduced-virulence surrogates. All tested strains exhibited the ability to survive the curd cooking step at 48°C and multiplied (3.4 Log CFU) in cheese within the subsequent 24 h. These findings indicate that genomic engineering did not exert any unintended effect on the double stx1-stx2 mutant behaviour, making it as a suitable less-virulent surrogate for conducting studies during food processing.

Dairy milk from cow and goat as a sentinel for tick-borne encephalitis virus surveillance.

Tick-borne encephalitis (TBE) is one of the most severe human tick-borne diseases in Europe. It is caused by the tick-borne encephalitis virus (TBEV), which is transmitted to humans mainly via bites of Ixodes ricinus or I. persulcatus ticks. The geographical distribution and abundance of I. ricinus is expanding in Sweden as has the number of reported human TBE cases. In addition to tick bites, alimentary TBEV infection has also been reported after consumption of unpasteurized dairy products. So far, no alimentary TBEV infection has been reported in Sweden, but knowledge about its prevalence in Swedish ruminants is scarce. In the present study, a total of 122 bulk tank milk samples and 304 individual milk samples (including 8 colostrum samples) were collected from dairy farms (n=102) in Sweden. All samples were analysed for the presence of TBEV antibodies by ELISA test and immunoblotting. Participating farmers received a questionnaire about milk production, pasteurization, tick prophylaxis used on animals, tick-borne diseases, and TBE vaccination status. We detected specific anti-TBEV antibodies, i.e., either positive (>126 Vienna Units per ml, VIEU/ml) or borderline (63-126 VIEU/ml) in bulk tank milk from 20 of the 102 farms. Individual milk samples (including colostrum samples) from these 20 farms were therefore collected for further analysis. Our results revealed important information for detection of emerging TBE risk areas. Factors such as consumption of unpasteurized milk, limited use of tick prophylaxis on animals and a moderate coverage of human TBE vaccination, may be risk factors for alimentary TBEV infection in Sweden.

Presentation of a Patient With Neurobrucellosis: A Case Report in Iran

Background: Brucellosis is a common zoonotic infection caused by the bacterial genus Brucella. It is one of the infectious diseases transmissible between humans and animals, and its clinical manifestations are very diverse and misleading. One of these manifestations is central nervous system involvement, which occurs in various forms. Better and more accurate identification of these diverse clinical manifestations can help physicians in the timely diagnosis and treatment of the disease. Case Presentation: In this study, we introduce a sixteen-year-old patient who complained of fever, low back pain, dizziness, and headache for two months. A detailed history of our patient revealed previous contact with sheep and consumption of unpasteurized milk. Further clinical tests confirmed the diagnosis of Brucella meningitis in this patient. Conclusion: Patients with brucellosis can show a wide variety of clinical symptoms, and knowing these different clinical forms can help physicians in the early diagnosis of the disease. In a country like Iran, where brucellosis is endemic, any patient who presents with complex and unexplained neurological complaints, especially those with a history of brucellosis, should be considered for neurobrucellosis.

Prevalence of Brucella spp. in milk from aborted and non-aborted animals in Dhamar governorate, Yemen.

Brucella infection in animals is considered a great problem in most countries of the world. Our study designed to determine the prevalence of brucella in field animal's milk in Dhamar governorate, Yemen. Total of 808 raw milk samples from non-aborted field animals, 120 milk samples from aborted animals, and 30 pasteurized milk samples were teste by Milk-Ring Test (MRT), milk-ELISA test, isolation and identification of brucella species, and antibiotic susceptibility. The prevalence of brucella in milk samples from field animals was 0.8%, 2.6%, and 2% in cows, sheep, and goat milk samples respectively with MRT, and 0.8%, 1.3% and 1.6% in cows, sheep and goat milk samples respectively with the milk- ELISA test. The prevalence rate in milk samples from aborted animals was 33%, 64% and 41.2% with the MRT and 39%, 49%, and 41.2% in cows, sheep and goats respectively with the milk-ELISA test. All pasteurized milk samples were negative for the milk-ELISA test. The result of isolation showed 0.1% of Brucella in milk samples from field animals while 9.2% from aborted animals. All isolates of Brucella species were sensitivities to rifampicin, doxycycline, kanamycin, gentamicin, streptomycin, tetracycline, and ciprofloxacin, while resistant to ampicillin, erythromycin, and novobiocin. In conclusion, the high prevalence of milk brucella especially in aborted animals needs focusing and build controlling strategies plans to decrease the losses to the economy and avoid transferred to humans with unpasteurized milk consumption.

Prevalence and Retrospective Insight on Tuberculosis in Human Patients in Cross River State, Nigeria; One Health Approach to its Control.

Tuberculosis (TB) is a major zoonotic disease of public health importance worldwide. Its burden is more in developing countries due to inadequate surveillance, co-infection with HIV/AIDS and poor social amenities; hence consumption of unpasteurized milk, contaminated meat and inhalation of infected droplets from animals or patients with active TB are the major risk practices. A survey was conducted on TB prevalence from 2013 to 2014 while patients records from TB and Leprosy units of hospitals in the three Agricultural zones (Ogoja, Ikom and Calabar) of Cross River State, Nigeria were assessed from 2000 to 2010. Out of 1,170 sampled patients, 8 (0.7%) were positive, of which 6 and 2 isolates were identified as M. tuberculosis and M. bovis, respectively. Out of 52,558 studied patients files, 235 (0.4%) were positive with varied annual prevalence; the highest (1.0%) and lowest (0.2%) in 2009 and 2011, respectively. The prevalence was higher in dry (0.9% and 0.5%) than the rainy season (0.5% and 0.4%), in females (0.9% and 0.5%) than the males (0.4% and 0.4%) in the survey and retrospective studies, respectively. The age distribution of TB among the patients were; (0% and 0.3%), (0.4% and 0.4%), (0.7% and 0.4%) and (1.5% and 0.7%) for those (≤ 18), (19-40), (41-60) and (> 60) yrs old in the survey and retrospective study, respectively. TB is prevalent in human patients in Cross River State hence, the need for sustainable campaign, continuous surveillance and private/ public health partnership in accurate and early diagnosis, treatment and one health approach to its control.

Public health threat with consumption of unpasteurized milk: Systematic review

Unpasteurized milk consumption is common throughout the globe, despite the negative consequence for consumer health. This review paper identified public health risks resulting from unpasteurized milk. Several keywords were used to search online, including Google Scholar, PubMed, Science Direct, and academic publications. Significant data were rigorously extracted and reported as per the PRISMA statement guideline. Individuals' risk from consuming raw milk was examined in 15 studies. According to a laboratory investigation report, raw milk contained several parasites and harmful bacteria in unpasteurized milk. These include campylobacteriosis, brucellosis, Staphylococcus aureus, streptococcus, salmonellosis, E. coli 0157, and other hazardous poisons like Aflatoxin M1. People are exposed to pathogenic microorganisms, parasites, and other dangerous toxic agents while consuming raw milk. Therefore, ensuring the safety and quality of raw milk through implementing hazard-critical control points during production and distribution is mandatory in the dairy industry to safeguard general public health.

Recent Emergence and Re-Emergence of Crimean Congo Hemorrhagic Fever and Q Fever Zoonotic Diseases: Major yet Ignored Infectious Diseases Worldwide

The continuing emergence or re-emergence of vector-borne zoonotic Q fever (caused by Coxiella burnetii) and Crimean Congo hemorrhagic fever (CCHF, caused by Orthonairovirus) include indispensable extraordinary threat around the world. Low infectious dose and long-term environmental residence are major risks. Wildlife and domestic livestock act as hosts or reservoirs of the CCHF virus and ticks are carriers. The disease also poses a threat to public health services owing to its epidemic potential, high case fatality ratio (up to 40%) as well as difficulties in treatment, prevention, and control. Q fever is another zoonotic febrile disease mainly affecting workers involved in farming livestock. The causative agent of Q fever causes abortion in livestock. The pathogen is shed in large numbers in the waste of infected animals (amniotic fluids and placenta during parturition) and is transmitted by inhalation of contaminated aerosols. Vaccination is the most effective way of protecting against Q fever. The main way to prevent Q fever is to avoid contact with animals, especially while animals are giving birth, or consumption of unpasteurized milk and contaminated dairy products. Due to the increasing importation of livestock to meet the growing demand for dairy and meat products, new diseases are likely to be introduced. In our growing globalized world, where trade between countries increases, it is necessary to conduct more research on zoonotic diseases and to monitor any possible disease introduction to new areas. A continuing surveillance program and pathogen testing are important in tracking the emergence of new pathogens.

Molecular detection of toxoplasma gondii DNA in goats (Capra hircus), sheep (Ovis aries), and donkey (Equus asinus) milk using PCR in East Azerbaijan province, Iran

Toxoplasmosis, a zoonotic infection that is significant for public health (immunocompromised patients, pregnant women) and veterinary medicine (economic losses in the herd), is caused by an intracellular protozoan parasite belonging to the phylum Apicomplexa called Toxoplasma gondii. Consumption of unpasteurized milk and contaminated undercooked meat is a significant source for humans. The present study aimed to determine Toxoplasma gondii DNA in sheep, goats and donkeys Milk kept in East Azerbaijan province using the PCR method based on the B1 gene. For this purpose, 100 milk samples, including 45 sheep, 45 goats and 10 donkeys, were collected from different regions of northwestern Iran using direct milking and then transferred to the Food and Aquatic Health Laboratory under refrigerated conditions. The results showed that out of 100 milk samples examined, 16 samples (16%) were contaminated, and Toxoplasma gondii DNA was detected in 5 (11.11%) sheep, 9 (20%) goats and 2 (20%) donkeys milk specimen, respectively. These findings indicated that Toxoplasma gondii contaminated the raw milk, a human infection source.

Prevalence, determinants, and antimicrobial susceptibility patterns of Campylobacter infection among under-five children with diarrhea at Governmental Hospitals in Hawassa city, Sidama, Ethiopia. A cross-sectional study.

Campylobacteriosis, is a zoonotic bacterial disease observed with a rising worldwide. It is becoming the most commonly recognized cause of bacterial gastroenteritis in under-five mortality in recent years. This study was done to determine the prevalence and determinants of Campylobacter infection among under-fives with acute watery diarrhea. This institutional-based cross-sectional study was conducted at governmental and private health institutions in Hawassa city. All outpatient under-five children who met the inclusion criteria from April 2021 to August 2021 were enrolled in this study. Demographic and clinical data were obtained using a standardized data collection tool. Stool samples were collected from each participant with a sterile container and inoculated on a campylobacter agar media. The isolates were identified by using biochemical tests and a disc diffusion technique was performed to determine the antimicrobial sensitivity patterns of the isolates. Data were entered and analyzed using SPSS version 21. Descriptive and Logistic regression analysis was applied to determine the determinants of Campylobacter infection. P-value < 0.05 was considered statistically significant. A total of 235 under-five children were enrolled in this study with a 100% response rate. Of these 130 (55.3%) and 105(44.7%) were males and females respectively with the age range of 2 months to 60 months with the mean age of 25 months. The majority of the 150 (63.2%) were rural residents. Of 235 under-fives with acute watery diarrhea, 16 (6.8%) patients were found to have Campylobacter infection with (95% CI, 3.8-10.2%). Consumption of pasteurized milk (AOR: 0.12; 95% CI 0.02-0.75, P<0.05), presence of domestic animals like cats, hens, and cows (AOR: 0.09: 95% CI 0.01-0.67, P<0.05), absence of handwashing practice before food preparation (AOR: 3.63, 95% CI 1.15-11.46, P<0.05) showed significant association with campylobacter infection. The antimicrobial susceptibility patterns of the isolated bacteria were 100% sensitivity to Azithromycin, Chloramphenicol, and Gentamicin, however; it was 100% resistant to Cephalothin. The associations of socio-demographic, environmental, and behavioral factors were compared and consumption of unpasteurized milk, the presence of domestic animal like the cat was significantly associated. Campylobacter infection showed a comparatively low prevalence in under-fives with acute watery diarrhea. In this study contact with cats, consumption of unpasteurized milk were associated with Campylobacter infection. The treatment approach of Campylobacter infection must consider the sensitivity profile of antibiotics as indicated in the study. We, therefore, recommend further studies to determine the species responsible for Campylobacter infection with other co-morbidities and the susceptibility pattern for each species to indicate appropriate antibiotic therapy.

A retrospective analysis of 1019 cases of tuberculous cervical lymphadenitis in a rural setup in 20 years

BackgroundThis article is to review cervical lymphadenitis due to tuberculosis (TB), their presentation, their aetiology, the methods used to diagnose them, the treatment modalities offered and the response to treatment. Methods1019 patients were diagnosed and treated for TB of the lymph nodes of the neck from 1st November 2001 to 31st August 2020 at a tertiary ENT hospital, Nadiad, Gujarat, India. Study consisted about 61% males and 39% females with the mean age being 37.3 years. ResultCommonest factor or habit among those diagnosed for tuberculous cervical lymphadenitis was consumption of unpasteurized milk. HIV and diabetes were the most common co-morbid conditions found with this disease. Swelling in the neck was most common clinical feature followed by loss of weight, formation of abscess, fever and fistula. Rifampicin resistance was found in 1.5% of patients among those tested for the same. ConclusionThe most commonly affected site for extra pulmonary TB is posterior triangle of neck than the anterior triangle. Patients with HIV and diabetes are at higher risk for the same. Testing for drug susceptibility has to be done due to increased resistant of drugs for extra pulmonary TB. GeneXpert and histopathological examination are important for its confirmation.

Outbreak of Alimentary Tick-Borne Encephalitis in Eastern Slovakia: An Analysis of Affected Patients and Long-Term Outcomes.

Objective: Tick-borne encephalitis (TBE) is an endemic zoonotic viral disease in many European countries and in the central and eastern parts of Asia. Slovakia reports the highest occurrence of alimentary tick-borne encephalitis in Europe, after the consumption of unpasteurized milk and cheese from domestic ruminants. In May 2016, an outbreak of tick-borne encephalitis that emerged after the consumption of sheep cheese occurred in eastern Slovakia. In total, 44 people were ill and 36 were hospitalized. Methods: Data from the 36 hospitalized patients at the Department of Infectology and Travel Medicine in Košice with TBE were retrospectively analysed from the medical documentation. The patients were contacted 3 years after discharge. Results: Twenty of the hospitalized patients had meningoencephalitis and 16 had meningitis. The main symptoms that occurred in all patients were fever and headache. Nuchal rigidity was seen in 50% of the patients. Three patients developed late systemic complications and another six patients had psychiatric complications. None of the patients died. Three years after the disease onset, 52% of contacted patients reported persistent discomfort. Conclusions: TBE is an infection with a wide range of clinical courses. Our findings suggest that alimentary-acquired TBE lead to severe disease and persistent discomfort.

Disease outbreaks linked to pasteurized and unpasteurized dairy products in Canada and the United States: a systematic review.

Pasteurization kills harmful microorganisms found in milk. While consumption of unpasteurized milk and its products is discouraged due to increased risk of infections, some individuals prefer unpasteurized dairy products. Our objective was to estimate the burden of illness from outbreaks arising from consumption of unpasteurized and pasteurized dairy products in Canada and the United States. We conducted a systematic review of dairy-associated outbreaks in Canada and the USA from 2007 onward. We searched MEDLINE, Embase, Cochrane Library, TRIP Database for guidelines, and North American government agency websites up to October 2020. We included outbreak reports where the pathogenic microbe was confirmed in both the patient and the dairy product through laboratory testing. Thirty-two disease outbreaks were linked to dairy consumption. Twenty outbreaks involving unpasteurized products resulted in 449 confirmed cases of illness, 124 hospitalizations, and five deaths. Twelve outbreaks involving pasteurized products resulted in 174 confirmed cases of illness, 134 hospitalizations, 17 deaths, and seven fetal losses. Listeria accounted for 10 out of 12 outbreaks from pasteurized products from 2007 through 2020. Public warnings about the risk of unpasteurized dairy consumption need to continue and pregnant women and immunocompromised hosts need to be made aware of foods at high risk of contamination with Listeria.

Infectious mimics of rheumatoid arthritis.

Rheumatoid arthritis (RA) can have various infectious mimics. As immunosuppressive agents used in treatment can aggravate the underlying infections, correct diagnosis of RA and ruling out infections is important. Numerous viral infections (Parvovirus B19, Hepatitis B, Hepatitis C, Chikungunya and other alphaviruses, human immunodeficiency virus (HIV) and various other viruses), mycobacterial infections (Poncet's disease, tubercular septic arthritis, and leprosy), bacterial arthritis, brucellosis and Lyme disease are among common infections that mimic RA. Widespread travel and tourism, especially to exotic areas, high risk sexual behavior and widespread use of immunosuppressive and chemotherapeutic agents has led to numerous outbreaks of infections in areas where these infections were never reported before. Hence, rheumatologists all over the world should be familiar with musculoskeletal manifestations of infections. History of travel, comorbid fever, skin rash, genital ulcers, urethral discharge, the consumption of unpasteurized milk, lymphadenopathy, tenosynovitis, low platelet count, and positive Mantoux test can offer potential diagnostic clues. Serological testing, cultures, specific radiological signs and deoxyribonucleic Acid (DNA) amplification techniques often aid in diagnosis. Treatment mainly consists of antimicrobial agents, analgesics, and nonsteroidal anti-inflammatory drugs (NSAIDs). However, immunosuppressive agents including steroids and disease modifying anti-rheumatic drugs (DMARDs) are needed occasionally in different refractory and prolonged illnesses. Most of the times, episodes of arthritis are self-limiting and respond to treatment of underlying cause. However, few infections like Chikungunya and Lyme's disease can lead to chronic arthritis as well.

Bovine Brucellosis: Epidemiology, Public Health Implications, and Status of Brucellosis in Ethiopia.

Brucellosis is a globally distributed zoonotic disease that causes serious problems in developing countries such as Ethiopia. Brucella abortus is the primary cause of brucellosis in cattle, and Brucella melitensis and Brucella suis also occasionally cause Brucella infection in cattle. Abortion and the retained fetal membrane are typical signs in females, whereas orchitis and bursitis are the known signs in male cattle. Brucellosis is typically transmitted to healthy cattle by direct or indirect contact with diseased cattle or their discharges. Humans can acquire brucellosis through the consumption of unpasteurized milk or milk products, and through contact with diseased cattle or their discharges. The occurrence of bovine brucellosis is affected by different factors related to the management system, host, and environmental factors. In Ethiopia, the occurrence of brucellosis is high in pastoral and mixed cattle management systems, wherever humans live closely with cattle and so have a higher probability of picking up the Brucella organism. The most suitable technique in the management of Brucella infection is the vaccination of young female cattle. Brucella abortus can also be eradicated by the isolation of diseased cattle, administration of immunizing agents, and test-and-slaughter methods. Therefore, it is important to implement applicable management techniques and to increase public awareness about the transmission of brucellosis, and further research should be conducted on brucellosis in high-risk groups.
