Sero-Prevalence of Small Ruminant Brucellosis in Three Selected Districts of Somali Region, Eastern Ethiopia
A cross-sectional study was conducted from November, 2011 to March, 2012 in three selected districts of Jijiga zone, Somali region, Ethiopia, aimed at determining the sero-prevalence and to identify potential risk factors of small ruminant Brucellosis. A total of 291 serum samples (100 from sheep and 191 from goats) were collected from extensive management system with no history of vaccination. All serum samples were initially screened by RBPT and positive reactors to RBPT were further tested by CFT for confirmation. Accordingly, the overall prevalence of Brucellosis in small ruminants was 1.37% (4/291).
