Serological and molecular detection of Leptospira spp in dogs.

INTRODUCTION

This study aimed to detect anti-Leptospira spp antibodies and Leptospira DNA in domestic dogs.

METHODS

Blood and urine from 106 dogs were evaluated by microscopic agglutination test (MAT) and polymerase chain reaction (PCR), respectively.

RESULTS

Six (5.7%) and one (1%) animals were positive by MAT and PCR, respectively.

CONCLUSIONS

These results show a low prevalence of infection by Leptospira spp. The absence of positive results for the Icterohaemorrhagiae serogroup indicates the small relevance of these dogs as sources of human leptospirosis.
