There are four species of Shigella: S. boydii, S. dysenteriae, S. flexneri, and S. sonnei. Figure 1. This photograph depicts the colonial morphology displayed by Shigella boydii bacteria cultivated on a Hektoen enteric agar surface.higellosis is spread by fecal-oral contamination, and primates are the hosts. The Shigella toxin affects the small intestine, causing a transduction of fluid into the intestinal lumen and subsequent diarrhea. The diarrhea causes destruction of the epithelial cells of the intestinal mucosa.
