BATISTA, C.S.A. et al. Seroprevalence and risk factors for leptospirosis in dogs from Campina Grande, State of Paraíba, Brazil. Arq. Bras. Med. Vet. Zootec. [online]. 2005, vol.57, suppl.2, pp.179-185. ISSN 1678-4162.

The prevalence of leptospirosis was investigated in dogs from Campina Grande city, State of Paraíba, Brazil, and the risk factors for infection were analyzed. Two hundred and eighty five blood samples were collected from dogs during the rabies vaccination campaign, in September 2003. The diagnostic method run for leptospirosis was the microscopic agglutination test, using a batch of 22 leptospiral serovars. The most prevalent serovar was found crossing the results of frequency and titer of agglutinins. The prevalence was 21.4% (95% CI = 16.8%-26.6%) and most frequent reactant serovars were autumnalis (7.4%), copenhageni (6%) and canicola (2.1%). The multivariate logistic regression analysis showed that the risk factors for leptospirosis were: age older than one year (odds ratio = 3.00; P = 0.006), mixed breed (odds ratio = 4.02; P = 0.011) and occurrence of floods in the area (odds ratio = 2.32; P = 0.039).
