Sero-Prevalence of Bovine and Human Brucellosis in Adami Tulu, Central Ethiopia

Abstract

A cross-sectional study was carried out to investigate the prevalence and risk factors of bovine and human brucellosis from November 2010 to March 2011 in and around Adami Tulu, Ethiopia. A total of 690 bovine and 93 human sera samples were randomly collected from selected 11 kebeles of the study area. The sera samples were screened by Rose Bengal Plate Test (RBPT) and all positive samples by the RBPT were subjected to Complement Fixation Test (CFT) for confirmation. Accordingly, 31(4.5%) bovine and 2(2.15%) human sera were found to be positive using RBPT. When retested with CFT, 30(4.3%) bovine and 2(2.15%) human sera were confirmed to be positive. There was statistically significant (P<0.05) variation in prevalence of the disease between sex, age and management system of animals. However, no statistically significant (P>0.05) variation was observed between sex and age of humans. Even though, the observed overall individual sero-prevalence of bovine brucellosis in the study area was not high, it deserves due attention due to its public health significance and thus physicians should also consider brucellosis as differential diagnosis of non-specific febrile diseases.
