Abstract

This paper verified possible alterations caused by a genotype II Toxoplasma gondii strain with respect to the total number and morphometry of the myenteric neurons in the terminal ileum and descending colon of rats. Eight rats were divided into two groups: control (n = 4) and experimental (n = 4). This group was inoculated orally with 20 tissue cysts of T. gondii from a genotype II strain (ME-49). Whole mounted from the terminal ileum and the descending colon were stained with Giemsa. There was not any neuronal loss on both organs. The neurons became hypertrophied in the terminal ileum, whereas morphometric alterations were not observed for the neurons in the descending colon.
