Abstract: A seroepidemiological survey of canine brucellosis was carried out in Beijing, China. Serum samples were taken from dogs admitted to the Beijing Companion Animal Hospital for immigration and emigration inspection, including dogs from 4 breeding farms and stray dogs (n = 1200, 14 districts), between January 2008 and April 2009. All of the sera were first tested and preselected by Rose Bengal plate agglutination test (RBAT), and the positive samples by RBAT were determined by tube agglutination test (TAT) again. Of the 1200 dogs studied, 60 (5%) were positive by RBAT, 21 (51.7%) of which were confirmed by TAT. The seroprevalence of canine brucellosis was 1.75% (21/1200), and 5 samples were smooth-type, while 16 samples were rough-type. Rottweiler, Husky, Chihuahua, and Poodle are predisposed to brucellosis, and it occurred in all age groups. The prevalence of female dogs was higher than that of males. This suggests that canine brucellosis infection exists in Beijing.
