Canine visceral leishmaniasis (CVL) is a chronic zoonosis caused by a protozoan called Leishmania (Leishmania) chagasi and has as vectors, the sandflies Lutzomyia longipalpis and Lutzomyia cruzi. The domestic dog is the most important reservoir in urban areas considering the zoonotic disease form and is responsible for maintaining the parasite in endemic foci. Aiming to assist the Superintendent of Policies for Comprehensive Health Care / Health State Department of Goiás (Spais / SES-GO) and the Department of Zoonosis Control from Goiânia (GO-DCZ) in epidemiological surveillance of the disease, this work investigated possible cases of CVL by using laboratory analysis. For this study, dogs seen at the Veterinary Hospital, School of Veterinary Medicine, Federal University of Goiás (HV / EV / UFG) with clinical suspicion of disease and symptomatic and asymptomatic dogs captured by DCZ-GO were analyzed. A total of 214 dogs were evaluated, and classified into three groups. Group 1 (GI): 33 dogs from DCZ with at least three clinical signs suggestive of LVC, Group 2 (GII): 141 clinically healthy dogs from DCZ and Group 3 (GIII): 40 dogs seen at the HV / EV / UFG with clinical suspicion of LVC. The frequency of animals classified as positive with different methods of diagnosis used in this study were: 5.6% (n = 12) in ELISA test, 9.35% (n = 20) in IFAT, 2.80% (n = 6) in the direct parasitological examination of skin imprints; 2.34% (n = 5) in direct parasitological examination of lymphonode, and 3.17% (n = 7) in PCR reactions of both the genderspecific protocol and the L. chagasi-specific. Considering the results and the conditions of the present study, it is concluded that there is casuistry in CVL series of symptomatic or asymptomatic dogs clinically attended in the city of Goiânia. The occurrence of Leishmania chagasi bearer dogs captured in the municipality of Goiânia were detected and the symptoms frequently observed in illness dogs carriers of L. chagasi in Goiânia are: conjunctivitis, lymphadenopathy, skin changes, cachexia and onychogryphosis.
