Seroprevalence of brucellosis in sheep in the Aksu Region of Xinjiang Uygur Autonomous Region, Peoples Republic of China, between 1990 and 2010

摘要

Seroprevalence of?brucellosis?infection in sheep between 1990 and 2010 in the Aksu Region, Xinjiang Uygur Autonomous Region,?People’s Republic of?China was determined by Rose Bengal Precipitation Test of Brucellosis (RBPT). The sera samples were analyzed according to?region, husbandry practice, sex, and age. A total of 208,438 sheep were tested, with overall brucellosis seroprevalence of 0.26% (550/208438). No statistically significant difference was found in terms of age and region. Seroprevalence in male sheep (0.53%, 52/9877) was higher than that in the females (p?=?0.02; OR?=?2.105, 95%; CI?=?1.581–2.803). Significant difference (p?=?0.03; OR?=?2.358, 95%; CI?=?1.843–3.017) was evident for rates for brucellosis in the scale breeding (0.13%, 73/55195) and backyard groups (0.31%, 477/153243). The current brucellosis serosurvey is expected to broaden the understanding of zoonotic infection in the region. We concluded that the control measures for brucellosis in the Aksu region sheep herds are effective.
