Shigella /Shi·gel·la/ (shi-gel´ah) a genus of gram-negative bacteria (family Enterobacteriaceae) which cause
dysentery. They are separated into four species on the basis of biochemical reactions: S. dysente´riae, S.
flexne´ri, S. boy´dii, and S. son´nei.

The genus Shigella consists of four species: S. dysenteriae (subgroup A), S. flexneri (subgroup B), S. boydii (subgroup
C), and S. sonnei (subgroup D). Shigella organisms may be very difficult to distinguish biochemically from Escherichia
coli. Brenner (1) considers Shigella organisms and E. coli to be a single species, based on DNA homology.

Shigella is also an invasive pathogen which can be recovered from the bloody stool of an infected host. Invasive
pathogens colonize the host's tissues as opposed to growing on tissue surfaces.
