title: [A new experimental model of cecal amebiasis in rats].
abstract: The young rat was used as an experimental model of caecal amebiasis by implanting, without injury of the caecum, a suspension of E. histolytica trophozoites gnotoxenic strain Rahman of high virulence. The degree of pathogenicity is demonstrated by the macroscopic aspect of caecum, by the density of trophozoites and by an anatomopathologic examination. As a correlation exits between all these macroscopic parameters and histology, a degree of illness is fixed which include several macro- and microscopic criteria. This model enables to observe the different phases of cicatrization and of recovering of young rats and so to appreciate the activity of antiamebic agents.
