Comparative study on Seroprevalence and Associated Risk factors of brucella Infection among sheep, goat and cattle in Somalia.

Abstract A cross-sectional Seroprevalence study using Multistage-sampling techniques, was conducted from the period between February 2019 to June 2020 at two livestock export quarantine stations and Livestock markets located in Bossaso, Somalia, to determine the Seroprevalence and associated risk factor of ruminant’s brucellosis. A total of 1068 sera samples were screened for Brucella antibodies using the Rose Bengal plate test, all-positive Serum samples and 80% negative samples with RBPT from sheep and goats and 50% negative sample from cattle were further tested using iELISA. The overall Seroprevalence rate of brucellosis in the current study was 1% and 1.84% using RBPT and i-ELISA respectively in Goats while 9.5% and 9% were positive in cattle using RBPT and i-ELISA respectively but there were no positive samples for sheep by both test of (RBPT) and (i-ELISA). The most significant Associated risk factors were species, castration and other risk factors such as age and Sex can affect status of brucellosis but their contribution are statistically insignificant.
