Cutaneous and conjunctival habronemosis in horses treated at the Veterinary Hospital of the Santa Catarina State University, Brazil.

Habronemosis, also known as habronemiasis or habronematidosis, is a parasitic disease of equids caused by the larval stages of Habronematidae nematodes (Habronema muscae, Habronema microstoma, and Draschia megastoma) that are transmitted by muscid flies. The presence of aberrant infective larvae in the cutaneous and conjunctival tissues of these hosts results in granulomatous, exudative, and ulcerated lesions, also known as "summer sores." In this study, we present a retrospective analysis of habronemosis cases in horses from the municipality of Lages, located on the Santa Catarina Plateau, a region with high altitudes and a temperate climate that differs from regions of Brazil where such parasitosis usually occurs.

[Canine tegumentar leishmaníasis in the town of Balneário Camboriú in the State of Santa Catarina].

Introduction: The increase in American tegumentary leishmaniasis (ATL) cases in 2005 was due to an outbreak that occurred in the towns of Itapema and Balneário Camboriú. This study aimed to determine the possible presence of infection by Leishmania sp in domestic dogs living in an endemic focus of ATL in the town of Balneário Camboriú and verify the existence of a correlation between the humoral and cellular immune responses, the presence of suggestive lesions and positivity in direct parasitological exams.

Methods: A total of 275 dogs were evaluated, examined according to clinic aspects, the development of delayed hypersensitivity to Immunoleish antigens and serological responses to the indirect immunofluorescence reaction and immunoenzymatic assay.
