EXPERIMENTAL CANINE MUCOCUTANEOUS LEISHMANIASIS (LEISHMANIA BRAZILIENSIS BRAZILIENSIS)
Author
Affilliation
Abstract in Portuguese
Quatro cães foram inoculados por via intredérmica com 3 x 10**6 promastigotos de Leishmania brasiliensis braziliensis. Três deles desenvolveram lesões no sítio do inóculo, mas uma úlcera mucosa foi detectada 16 meses após o inóculo. Os achados foram similares áqueles verificados na infecção canina natural, bem como na doença humana. Estes resultados sugerem que o cão pode representar um modelo experimental para a infecção causada pela L. b. brasiliensis.
Abstract
Four mongrel dogs were intradermically inoculated with 3 x 10**6 Leishmania braziliensis braziliensis promastigotes. Three out of the four animals developed cutaneous lesions respectively 4, 7, and 8 months after. The fourth dog did not develop lesion at the inoculation site, but a mucosal ulcer was seen 16 months after the inoculum. Clinical, histopathological, and serological findings were similar to what is found in natural canine infection as well as in the human disease. These results suggest that dogs may be an useful model for L. b. braziliensis infection.
