摘要：
A direct search for parasites were used as the diagnostic test to determine the frequency of Leishmania spp. infection in dogs (Canis lupus familiaris) under veterinary clinical care in the city of Araguauina, Tocantins, Brazil. For this approach, lymph node cell samples were collected using needle aspiration from 649 dogs of different breeds and ages. Two hundred and sixty four (40.7%) dogs tested positive for amastigote forms of Leishmania spp. Furthermore, 202 (76.5%) dogs that tested positive showed some clinical sign of disease, while 62 (28.4%) dogs were asymptomatic. Dogs < 2 years old or those that lived alongside poultry species in peri-domicile areas had a greater chance of infection (P<0.05). Our results revealed the importance of frequently monitoring leishmaniasis in dogs, and the need to train veterinary professionals who work in high-transmission areas on the clinical diagnosis of canine visceral leishmaniasis.
