Abstract

Visceral leishmaniasis (VL) is a disease with high mortality, neglected, with worldwide distribution, mainly in South America, with greater notification in Brazil. The domestic dog is the main reservoir of VL in endemic regions and plays a fundamental role in the maintenance and expansion of this disease. Therefore, knowledge of pathogenesis, immune response and clinical manifestations are essential for the establishment of preventive and control measures for canine visceral leishmaniasis (CVL). The West Paulista region has an increasing number of dogs diagnosed with CVL, however, there are no studies with this population of animals. This project aims to evaluate the superficial lymph nodes of dogs diagnosed with VL by the cytopathological and histopathological exams and determine the parasitic density, immune response and morphological changes, correlating the results with the clinical manifestations of the disease.
