Leishmania enriettii in guinea pig (Cavia porcellus) in southern Brazil

ABSTRACT: Leishmaniasis is a parasitic disease with a worldwide distribution, transmitted to animals and humans through the blood meal of sand flies, caused by protozoa of the genus Leishmania. This report aims to describe the clinical, pathological, and molecular findings of mucocutaneous leishmani...

description ABSTRACT: Leishmaniasis is a parasitic disease with a worldwide distribution, transmitted to animals and humans through the blood meal of sand flies, caused by protozoa of the genus Leishmania. This report aims to describe the clinical, pathological, and molecular findings of mucocutaneous leishmaniasis caused by Leishmania enriettii in a guinea pig (Cavia porcellus). The animal presented ulcerated skin lesions in the right pinna. Samples from the lesion were evaluated by cytology, revealing the presence of amastigote forms of Leishmania spp. Histopathology showed a dermal inflammatory infiltrate consisting of macrophages, multinucleated giant cells, lymphocytes, plasma cells, and heterophils. The foam cells contained parasitophorous vacuoles filled with amastigotes. Molecular characterization identified the species as L. enriettii. The diagnosis of mucocutaneous leishmaniasis was based on morphological findings (macroscopic and microscopic) associated with molecular biology tests that allowed defining the etiological agent of the disease.
