FATORES DE RISCO E CLASSIFICAÇÃO CLÍNICA ASSOCIADOS À SOROPOSITIVIDADE PARA LEISHMANIOSE VISCERAL CANINA

Abstract

In order to evaluate the risk factors and clinical classification associated with seropositivity for Canine Visceral Leishmaniasis (CVL) in the city of Colares, Pará State, 435 serum samples were collected from dogs of both sexes, aged from 4 months, with or without standard breed and with or without clinical symptoms suggestive of disease, from the neighborhoods and the rural areas, and analyzed. Serology was performed using immunoenzymatic assay (ELISA/S7) and Immunofluorescence Assay (IFA) methods in fixed slides with antigens from Leishmania infantum. Sex did not present statistic significance (P>0.05). There was significant prevalence of LVC regarding age and clinical classification (P < 0.05). The prevalence was higher for dogs aged less than 2 years and for those classified as clinically symptomatic, and onychogryphosis and skin changes were the most common clinical changes.
