Seroprevalance of Brucellosis in Small Ruminants and Associated Risk Factors in Ziway Dugda Woreda, Arsi Zone Southeast Ethiopia

Abstract

A cross sectional sero-prevalence study was conducted on 384 small ruminants in Ziway Dudga district, Ethiopia to investigate the status of small ruminants’ brucellosis and identify potential risk factors. Serum samples collected from 202 sheep and 182 goats were analyzed using Rose Bengal Plate Test (RBPT), and those who were RBPT positive was subjected to Complement Fixation Test (CFT). The overall sero-prevalence was 1.56% (6/384). The prevalence of brucellosis among sheep and goats was 4 (1.04%) and 2 (0.52%), respectively. Small ruminants brucellosis in female and male animals was 5 (1.30%) and 1 (0.26%), respectively. Sero- prevalence of brucellosis in adult animals (1.30%) was higher than that of young animals (0.26%). The prevalence with a history of retained fetal membrane (6.7%) was higher than animals with no history of retained fetal membrane (1.6%). The result of study showed that there is no statistical association between species, sex, age and history of retained fetal membrane (P>0.05). The prevalence among females with a history of abortion (16.7%) was significantly higher (P<0.05) than those without history of abortion (1.2%). Generally, the sero-prevalence of small ruminants brucellosis found in Ziway Dudga area was low and the sero-prevalence was closely associated with history of abortion. Training should be provided for farmers and livestock attendants regarding effective sanitary and hygienic management practices during handling of animals and animal products such as aborted fetal materials and other body secretions.
