Abstract

Pre-print to the Original article in SpringerLink: http://www.springerlink.com/index/a1552t5171670g21.pdf,A cross-sectional study was conducted between January 2007 and February 2008 to estimate seroprevalence of brucellosis and identify risk factors associated with Brucella infections in commercial cattle in 3 districts of Lusaka province (Chongwe, Luangwa, Kafue; n=849) and in one rural district from the Central province (n=48). A total of 897 serum samples were randomly collected from 55 farms along with animal level data such as sex, age and parity. Sera were screened for presence of anti-Brucella antibodies using Rose Bengal Test (RBT) and positive samples were confirmed using competitive enzyme linked immunosorbent assay (c-ELISA). At animal level, seroprevalence was estimated at 7.9 % (95% CI: 4.4-11.4%) in the Lusaka province and 18.7 % (95% CI: 7.5-29.9%) for Chibombo district. Brucellosis seroprevalence varied according to district, with Chongwe district recording the highest compared to other districts. Seroprevalence also varied according to sex with bulls (n =96) having higher seroprevalence (12.5%; 95% CI: 3.8-21.1 %) compared to females (8.1%; 95% CI: 4.6-11.6). Similarly, seroprevalence varied according to age groups, with the age category 1-4 years recording the highest (10.7%). The study recorded relatively low Brucella seroprevalence in commercial farms in Lusaka, compared to the traditional small-scale farms. We suggest that testing and stamping out of infected animals is likely to improve the situation and significantly reduce the public health risk associated with Brucella infections in animals.
