Summary (continued)

Male goats and sheep were twice as likely to test positive as females (relative risk [RR]: 2.04; 95% confidence interval [CI]:1.7–3.4; c2 = 21.05, p < 0.05). Adults (older than 1.5 years) were three times more likely to test positive than younger animals (RR: 2.76; 95% CI: 1.14–6.73; c2 = 5.18, p < 0.05). Goats were around four times more likely to be infected than sheep (RR: 3.8; 95% CI: 2.4–6.1; c2 = 36.99, p < 0.05). Brucella melitensis was isolated from 2 of the 14 samples analysed. The widespread distribution of brucellosis in goats and sheep in these areas justifies the use of control measures to minimise the economic losses and public health hazards.
