Seroprevalence of Brucellosis reactor among goats and sheep on an agribusiness farm in a peri-urban of Bogor, Indonesia

Abstract

Brucellosis in small ruminants is a challenge in agriculture, particularly livestock development. In Indonesia, the determinants of the epidemiology of the disease are not widely known or reported. This study aimed to investigate the brucellosis reactor in goats and sheep to provide evidence for controlling the disease. A total of 216 sera samples (102 sheep and 114 goats) from an agribusiness MTF farm in a peri-urban of Bogor were collected and analyzed with RBT and CFT. The results showed that the seroprevalence was high at 21.30% (95% CI; 15.8-26.8). Brucellosis seroprevalence did not differ significantly between goats and sheep with 22.81% and 19.61% respectively, testing positive for the disease. Brucellosis reactor seroprevalence was significantly higher in older animals (over 2 years) than in younger animals (0-2 years), at 30.38% (95% CI, 20.2-40.5) and 16.06% (95% CI, 9.9-22.2), respectively. Increasing age was significantly associated with seropositivity (OR=2.28). These findings indicate a high prevalence of brucellosis reactor among small ruminants in the peri-urban of Bogor, Indonesia, and require appropriate precautions. Given the high density of people in the study site, this could endanger public health and lead to significant production losses.
