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.
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.
In developing countries such as Ethiopia, leech infestation is a neglected parasitic disease of livestock. Although such studies are important, little attention has been paid to the occurrence, impact and risk factors of leech infestation in livestock in Ethiopia. The objective of the current study was to assess farmers' knowledge of leech infestation and control practices, and to estimate the prevalence and risk factors of leech infestation in domestic animals in northwestern Ethiopia. A cross-sectional study was conducted in three districts of North Gondar Zone from February 2021 to August 2021. Livestock (n=2040) and 300 respondents for questionnaire survey were randomly selected. According to the results of the questionnaire survey, 98.67% of the respondents were aware of leech infestation, the effects of leeches and the locally available control methods. Cattle had the highest prevalence (10.08%), followed by horses (3.67%), goats (2.48%), and sheep (2.02%). Using a chi-square test, a significant association was found between the prevalence of leech infestation and risk factors such as animal species, sex, age, body condition, and season (p < 0.05). Observation of the water bodies revealed that leeches become more active when the water becomes slightly warmer due to sunlight, and they become especially active when the animals want to drink from the water. The current results indicate that leech infestation is the biggest problem for livestock in the study areas, so cost-effective and environmentally friendly control methods must be used.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
