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

- We analyzed the jejunum of rats infected with different doses of T. gondii.
- The tested dose was from 10 to 5000 oocysts orally.
- NADHd-p and NADPHd-p neuronal atrophy was observed.
- Morphological and morphometric alterations were found in the infected groups.
- Hypertrophy of the muscle was observed in the group infected with 5000 oocysts.
