Summary: This study aimed to investigate the seroprevalence and associated risk factors of infectious bursal disease (IBD) in backyard and intensively managed chickens in western Oromia, Ethiopia. The study found a high prevalence of IBD and significant statistical associations with factors such as chicken rearing practice, origin, and breed. The questionnaire survey revealed a lack of knowledge among poultry keepers about IBD and other chicken diseases.

Summary: In Ethiopia, chicken disease outbreaks and mortalities are often caused by a respiratory syndrome called fengil. This study aimed to determine the prevalence of key respiratory pathogens in chicken populations in Ethiopia. The seroprevalence of infectious laryngotracheitis virus (ILTV), infectious bronchitis virus (IBV), Newcastle disease virus (NDV), Mycoplasma gallisepticum (Mg), and avian metapneumovirus (aMPV) was investigated. The study found a high level of exposure to all pathogens, with aMPV, ILTV, and IBV being detected for the first time in the East Shewa Zone. Multiple pathogen exposure was common, especially in the scavenging system.

Summary: Infectious bronchitis virus (IBV) and avian reovirus (ARV) are widely prevalent in backyard chickens in the studied area of southern Mozambique. The overall seroprevalence of both viruses was high, highlighting the importance of implementing chicken health development programs.

Summary: This study conducted molecular surveillance of Newcastle disease virus in nonvaccinated village chickens in Central Rift Valley of Oromia, Ethiopia. Out of 84 pooled swab samples, 15.48% tested positive for APMV-1, with the highest prevalence recorded in Adama. The study highlights the importance of implementing molecular surveillance in live poultry markets and village chickens.

Summary: This study examined the sources, pathways, and risks associated with environmental lead in urban gardens, domestic chickens, and eggs. The findings indicate that many inner-city homes may not be suitable for keeping chickens, highlighting the need for further research on the production and consumption of domestic food.

Summary: This study investigated the seroprevalence and potential risk factors of brucellosis among dairy cow owners and farmworkers in selected sites in the central highlands of Oromia, Ethiopia. The study found a low seroprevalence of brucellosis in the area, but limited knowledge among respondents. Human brucellosis was significantly associated with human housing, contact with aborted fetus, and consumption of raw milk and other animal products. Public awareness and collaboration between veterinary and medical health professionals need to be strengthened.

Summary: This study investigated the seroprevalence and risk factors of Newcastle disease (ND) in unvaccinated backyard chickens in Kindo Koisha district, Wolaita zone, Ethiopia. The results showed that ND is prevalent among poultry and backyard farming communities, with crossbreed chickens and larger flock sizes being associated with higher risk of infection. The study suggests the implementation of vaccination campaigns and effective extension programs to raise awareness about the disease.

Summary: This study investigated the hygienic handling practices of fish in three towns in Oromia. The results revealed a wide range of unhygienic practices along the fish production and supply chain, lack of infrastructure for post-harvest handling and processing, inadequate transportation facilities, and knowledge gaps regarding fishborne diseases.

Summary: The study aimed to assess and identify determinants of farm mechanization level. Primary data was collected through personal interviews of 397 farm households in four districts of central and southeast Oromia region in Ethiopia. The study used the Mechanization Index (MI) to estimate farm mechanization level and employed the Tobit model to analyze determinants. Gender, education, farming experience, labor availability, social capital, location, access to roads and service providers, market participation, land ownership, fragmentation and livestock size were found to be statistically significant determinants. Land consolidation, infrastructure availability, and education/training were recommended to enhance mechanization level.

Summary: The aim of this study is to track the production of gp in IBDV-vaccinated and challenged birds. The study found that BSDCs have a dual function, as they can either release extracellular gp or form intracellular corpuscles. Moreover, IBDV infection accelerates the transformation of BSDCs to macrophage-like cells. These findings contribute to our understanding of the mechanisms of IBDV infection and have important implications for the immunosuppressive status of chickens.

Summary: The study demonstrated that recombinant VP3 (rVP3) showed high sensitivity and specificity as a diagnostic reagent in an enzyme-linked immunosorbent assay (ELISA) compared to a commercial test, especially for vaccinated animals. rVP3 was able to detect antibodies in non-vaccinated chickens, potentially developed against circulating IBDV strains. Evaluation of VP3 full-length protein can be used to assess post-vaccination immunological status of chickens with low cost.

Summary: This study investigated the seroprevalence of visceral leishmaniasis (VL) and associated factors among the asymptomatic pastoral community in Dire District, Oromia Region, Ethiopia. The results showed that high family size, sleeping or staying under acacia tree, presence of cracked house walls, presence of termite hills, availability of water points, and presence of domestic animals were significantly associated with VL infection.

Summary: The pathogenicity and persistence of the variant infectious bursal disease virus (vaIBDV) and very virulent infectious bursal disease virus (vvIBDV) were comparatively evaluated in chickens. The study found that the Malaysian variant severely damaged the immune organs of chickens and was more persistent in bursal tissue than vvIBDV.

Summary: The study showed that dexamethasone can reduce mortality in chickens infected with vvIBDV, while treatment with aspirin or vitamin E plus selenium did not affect mortality. The bursa of Fabricius appeared to have shrunk in chickens following infection.
