Resumo
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.
