Resumo: | Samples of stomach, duodenum, jejunun, ileum, cecum and colon were collected for Giemsa-smears ("imprints") from one asymptomatic mongrel dog, naturally infected with Leishmania (L) chagasi. Other fragments were obtained and fixed in formalin (10% and buffered) for histopathological and immunohistochemical studies. The immunohistochemistry was carried out by a streptavidin-peroxidase technique and it allowed to detect amastigote forms of Leishmania chagasi in the different paraffin gut sections. The principal lesion observed was a discrete to moderate chronic inflammatory reaction in the mucosa and submucosa in all fragments of the gastrointestinal tract (GIT). A chronic cellular exsudate was observed in all GIT tissues and it was composed by mononuclear cells (monocytes, plasmocytes and lymphocytes). A comparison between the two techniques showed that the immunohistochemistry study is the best method to detect amastigote forms of Leishmania.
