Abstract
INTRODUCTION
Leishmania species cause skin, mucosal, and disseminated lesions. We studied the effects of three Leishmania species on ileal morphology in mice.
METHODS
BALB/c mice were intraperitoneally inoculated with Leishmania (Leishmania) amazonensis, Leishmania (Viannia) braziliensis, and Leishmania (Leishmania) major (4 animals/group). After 72h, the ilea were collected and histologically processed.
RESULTS
Following inoculation, the goblet cell and intraepithelial lymphocyte populations increased, while Paneth cell number and crypt width decreased. In addition, enterocyte size, villi height, and mucosa, submucosa, and muscular tunic thickness increased.
CONCLUSIONS
Leishmania modified the quantity of cells in and morphology of mice ilea.
