Abstract


The transfusion of blood components is common in a veterinary clinic; however, the safety of this therapeutic measure cannot always be guaranteed. Studies show a high risk of haemoparasite transmission during blood transfusion in canines. These parasites include Leishmania chagasi, Anaplasma platys, and Ehrlichia canis, which are endemic to the city of Cuiabá. This study aimed to evaluate the occurrence of L. chagasi, Trypanosoma cruzi, Babesia (canis) vogeli, A. platys, and E. canis in canine blood donor candidates, and identify possible factors associated with the infection of these agents. Sixty-six canines were evaluated using serologic and molecular tests, for the presence of the Leishmania species. While one canine sample showed a positive result for L. chagasi with indirect fluorescent antibody test, with titer of 1:40, and seven canine samples were positive using DPP, all other samples were negative when using PCR and ELISA. All canines were negative for T. cruzi when using PCR. The B. (c.) vogeli infection was identified in one canine and A. platys was identified in six canines. E. canis was identified in 17 canines, with a prevalence of 25.7%. There were no significant factors associated with the infection of the pathogens investigated. Given the observation of infection, even in the absence of clinical symptoms, emphasis must be placed on the need for the use of more sensitive and specific diagnostic methods for the screening of donor canines.
