Toxoplasma gondii infection causes structural changes in the jejunum of rats infected with different inoculum doses.

Aim: To evaluate the mucosal tunic and submucosal plexus of the jejunum of rats infected with different inoculum doses of Toxoplasma gondii.

Main Methods: Rats were infected with different inoculum doses (50, 500, 1000 and 5000 oocysts) of the T. gondii for 30days, while a control group (CG) received saline solution.

Different inoculum loads of Toxoplasma gondii induce reduction of myenteric neurons of the rat colon.

Toxoplasmosis, a disease caused by Toxoplasma gondii, is an important health problem, especially in immunocompromised hosts. T. gondii uses the gut wall as an infection gateway, with tropism for muscular and nervous tissues causing intestinal alterations, including some in the enteric nervous system.

Kinetics of acute infection with Toxoplasma gondii and histopathological changes in the duodenum of rats.

Toxoplasma gondii crosses the intestinal barrier to spread into the body. We investigate the intestinal wall and epithelial cells of the duodenum of rats infected with T. gondii during different time points of acute infection.

Oral dependent-dose toxoplasmic infection model induced by oocysts in rats: Myenteric plexus and jejunal wall changes.

Toxoplasmosis is a widely distributed disease caused by the protozoan Toxoplasma gondii that is mainly transmitted orally. Once ingested, the parasite crosses the intestinal barrier to reach the blood and lymph systems to migrate to other regions of the host. The objective of this study was to evaluate the changes in the myenteric plexus and the jejunal wall of Wistar rats caused by oral infection with T.
