Dysentery in Humans and Primates
- Shigella is are enteroinvasive,
- Penetrate the intestinal mucosa.
- Cause necrosis in patches of mucosa.
- Shigella do not invade beyond the lamina propria to the bloodstream.
- Invasive potential is carried by a large plasmid.
- Relates to the ability to survive inside the host cells.
- Some strains produce Shiga toxin.
- Related to vero cytotoxin of some pathogenic strains of E.coli.
