Serological Survey of Canine Leptospirosis in Southern China

The present study conducts a serological survey on the presence of canine leptospirosis in domestic dogs using ELISA kit. A total of 314 household dogs (168 females and 146 males) in Chongqing, Kunming, Nanchang, Fuzhou, Guangzhou, Shenzheng, and Nanning in Southern China were examined. Of the 314 dogs, 23 (7.3%) were seropositive for leptospirosis. No statistically significant difference was observed in terms of sex and age in the seroprevalence of leptospirosis, but statistically significant differences were observed among different regional groups in the seroprevalence of leptospirosis (P<0.05). The results of this survey indicate that the control and treatment of leptospirosis have been effective in some cities of Southern China. However, further implementation of integrated strategies is necessary to prevent and control leptospirosis in dogs
