Abstract

The One Health concept emerged to highlight the inseparable link between animal, human and environmental health. In this context, American Visceral Leishmaniasis (AVL) is considered an important public health disease in Brazil, due to its increasing geographic expansion and in the incidence of human cases. AVL is a parasitic and zoonotic disease caused by Leishmania (Leishmania) infantum (syn. chagasi) and transmitted by sandflies of the genus Lutzomyia. Dogs are considered the main reservoirs of the parasite in urban areas. The diagnosis of AVL is based on epidemiological, clinical and laboratory aspects. The demonstration of the presence of the parasite through direct examinations in biological tissues of the host is the diagnosis of choice, mainly in municipalities where the transmission of AVL has not yet been confirmed. Several methodologies can be applied for this purpose. The objective of this work is to present the cytological, anatomopathological and molecular techniques in formalin fixed and paraffin embedded samples for the diagnosis of visceral leishmaniasis in humans and dogs. These data are complementary to the present study at the First International Symposium on Visceral Leishmaniasis, held on April 23 and 24, 2018, and organized by Adolfo Lutz Institute in São Paulo, Brazil.
