Seroprevalence and associated risk factors of equine herpesvirus type-1/-4 in selected districts of Northwest Amhara, Ethiopia.

This study aimed to estimate the prevalence, determine the distribution, and identify the epidemiological risk factors of EHV-1/-4 infections in selected districts of Northwest Amhara Region. 460 serum samples were collected from equines using multistage cluster sampling technique, and a competitive Enzyme-linked immunosorbent assay (cELISA) was performed. Various risk factors for the occurrence of EHV-1/-4 were considered. Statistical analysis was performed using R version 4.3.1. 65.9% (303) equids were tested positive for antibodies against EHV-1/-4. Based on district, the highest prevalence was recorded in Wogera (86.1%), while the lowest was in Debark (47.4%). There was a significant difference (p <0.05; 95% CI: 1.1067993-3.682843) in the prevalence of EHV-1/-4 among species and donkeys are 2.019 times more likely to get an EHV infection than horses. The prevalence of EHV-1/-4 was highest in equids with the age of 3-8 years and lowest in < 3 years, and the difference was statistically significant (p <0.05; 95% CI: 1.9812042-6.771820). Statistically significant variation (p <0.05; 95% CI: 1.1173822-2.684013) was also observed between sex of equids in which females had 1.73 times higher chance to get EHV infection than males. Higher prevalence was found in lactating equids (81.6%), followed by pregnant equids (74.6%), and dry equids (66.4%). Generally, this study indicated a high and wide distribution of EHV-1/-4 infection in the study area, which needs due attention. Devising strategies to prevent and minimize the spread and occurrence of the infection is crucial.

Knowledge, Attitude, and Practices on Food Safety among Food Handlers Working in Public Food Service Establishments in Lemi Kura Subcity, Addis Ababa, Ethiopia.

Foodborne diseases, resulting from poor food handling and sanitation practices, are common public health problems globally. The primary contributing factors to potential foodborne disease outbreaks are often attributed to the poor perception and practices of food handlers regarding food safety. This study is aimed at assessing the knowledge, attitude, and practices of food handlers working in public food service establishments in Lemi Kura subcity, Addis Ababa, Ethiopia. A cross-sectional study was conducted from December 2022 to September 2023, involving 400 food handlers from 20 randomly selected public food service establishments. Data were collected using a structured interview-administered questionnaire and an observational checklist. The collected data were entered into Microsoft Excel and then transferred to SPSS version 20 for analysis. Descriptive statistics were employed to summarize the data, and Pearson's chi-square test was used to evaluate the association of sociodemographic factors with the knowledge, attitude, and practices of food handlers towards food safety. Of the 400 food handlers, 65.5% had good knowledge about food safety. All food handlers were knowledgeable that washing hand before handling food will reduce risk of poisoning, bacteria are the main cause of food poisoning, and temperature plays a big role in bacterial growth. This study also revealed that 65.3% of the food handlers had good attitude towards food safety and 55.3% of food handlers had good food handling practice. Based on the observation, 38.5% of food handlers had good food handling practice. Taking training, age, and work experience of food handlers have statistically significant (P < 0.05) association with good attitude towards food safety. Additionally, taking training, educational level, employment, and work experience of food handlers have statistically significant (P < 0.05) association with good practice towards food safety. However, there was no statistically significant association between all sociodemographic factors and knowledge about food safety. Good knowledge and attitude were also associated with good food handling practices of the respondents. Based on the observation, there was a statistically significant association between employment status and good food handling practice. In conclusion, the findings suggest the necessity for implementing formal educational and training programs aimed at positively influencing the knowledge and attitude of food handlers, subsequently improving their food handling practices.

Situational analysis of antimicrobial resistance, laboratory capacities, surveillance systems and containment activities in Ethiopia: A new and one health approach.

Antimicrobial resistance (AMR) has become a health, environmental, and economic threat around the globe. It is rising in Ethiopia. This analysis was designed to determine the current status of AMR on major bacterial pathogens, laboratory capacities, surveillance systems, and containment activities in the country. Data were collected from published literature and then supplemented by interviews with ten experts from key stakeholders. Data collections were guided by the AMR Situational Analysis Tool developed by Food Safety Officers at the Food Systems and Food Safety Division of the Food and Agriculture Organization of the United Nations. Published articles indicated the presence of gaps in knowledge, attitude, and practices by health professionals, students, and the community. AMR rates among E. coli, Salmonella, Staphylococci, and Campylobacter isolates ranged from 3.69-88.41, 4.66-87.74, 17.03-85.08, and 8.41-86.63% to commonly prescribed antimicrobials, respectively. Microbiology laboratories are available. However, a considerable number of laboratories didn't have the basic equipment and consumables. AMR surveillance and reporting system have been established. The national strategic plan has been developed and updated three times. To contain AMR, a governance framework and regulations have been prepared. However, most of them were not fully implemented at all administrative levels. In conclusion, there was a high rate of AMR in the country; some activities have been conducted to prevent and contain AMR. However, more interventions and sustainable activities have to be performed to increase awareness, prevent and contain infectious diseases, rational use antimicrobials and generate more evidence in the country.

Application of Advanced Imaging Modalities in Veterinary Medicine: A Review.

Veterinary anatomy has traditionally relied on detailed dissections to produce anatomical illustrations, but modern imaging modalities, now represent an enormous resource that allows for fast non-invasive visualizations in living animals for clinical and research purposes. In this review, advanced anatomical imaging modalities and their applications, safety issues, challenges, and future prospects of the techniques commonly employed for animal imaging would be highlighted. The quality of diagnostic imaging equipment in veterinary practice has greatly improved. Recent advances made in veterinary advanced imaging specifically about cross-sectional modalities (CT and MRI), nuclear medicine (PET, SPECT), and dual imaging modalities (PET/CT, PET/MR, and SPECT/CT) have become widely available, leading to greater demands and expectations from veterinary clients. These modalities allow for the creation of three-dimensional representations that can be of considerable value in the dissemination of clinical diagnosis and anatomical studies. Despite, the modern imaging modalities well established in developed countries across the globe, it is yet to remain in its infancy stage in veterinary practice in developing countries due to heavy initial investment and maintenance costs, lack of expert interpretation, a requirement of specialized technical staff and need of adjustable machines to accommodate the different range of animal sizes. Therefore, veterinarians should take advantage of these imaging techniques in designing future experiments by considering the availability of these varied imaging modalities and the creation of three-dimensional graphical representations of internal structures.

Seroprevalence of Bovine Brucellosis in Ethiopia: Systematic Review and Meta-Analysis.

Brucellosis is an infectious and widespread zoonotic disease caused by bacteria of the genus Brucella and can induce considerable human suffering and huge economic losses in animals. Thus, the aim of this study was to conduct a systematic review and meta-analysis on the seroprevalence of bovine brucellosis in Ethiopia. PubMed, Science Direct, African Journals Online, and Google Scholar were used to search the articles. All references were screened and articles, which reported seroprevalence of bovine brucellosis in Ethiopia were included in the study. Meta-analysis using random-effects models was made to calculate the pooled seroprevalence of brucellosis. This review included 15 papers. The estimated pooled seroprevalence of brucellosis was found to be 3.0% (95% CI: 2.0, 4.0). The subgroup analysis showed that there was a statistically significant association between the disease and geographical location, setting, laboratory technique employed and study years. Also, there was some evidence of publication bias (Egger's test, p = 0.0003) on studies reporting the prevalence of brucellosis in Ethiopia. This review proves a high seroprevalence of brucellosis in the country and appropriate control strategies are recommended. Moreover, further study on the risk factors is also required to develop cost-effective preventive strategies.
