Leptosporosis is a re-emergent zoonosis associated to close contact between man and dogs. It is important to determine whether the canine leptospirosis risk factors are similar to those of man or are variables exclusive to the species habitat and management. The objective of this study was to identify the individual and environmental variables most frequently associated with seropositive dogs attended in the Veterinary Hospital at Londrina State University. One hundred and sixty dogs of both sexes not vaccinated against leptospirosis were studied over a 13-month period (march 1997 to april 1998). All the animals were submitted to the microscopic aglutination test and to the direct urine test. An epidemiological questionnaire filled out for each one to investigate variables that could be associated with this infection and the results obtained were submitted to the c2 test. Antibody titers ³ 100 were detected in 40 dogs and were more frequent against the pyrogenes serovar (45,00%). Twenty-four animals were positive in the direct urine test. The analysis of the variables pointed as a risk factor for canine leptospirosis the habit of hunting rodent (OR = 4.22, 1.89£IC95%£9.50), the presence of flooded areas near the houses (OR = 2.86, 1.32£IC95%£6.22) and access to the street (OR = 2.57, 1.19£ IC95%£5.59). The results serve as a warning about the possibility of human exposure to some risk factors that these dogs are exposed to.
