Report of new cases of Trypanosoma caninum in Brazil.

INTRODUCTION

Trypanosoma caninum is a protozoan species recently described in dogs, whose occurrence has been reported in areas of overlap with visceral leishmaniasis.

METHODS

Trypanosoma sp. were isolated from nine dogs and characterized by molecular methods.

RESULTS

PCR and sequencing confirmed the presence of T. caninum in all dogs, revealing two new areas of transmission: Barra Mansa and São João do Piauí.

CONCLUSIONS

The nine new cases described, when added to those already published, account for 62 cases of natural infection by T. caninum and show the geographical spread of this species to new areas, where other trypanosomatids circulate.
