Shigella

 [shĭ-gel´ah]
a genus of gram-negative, facultatively anaerobic, nonmotile, rod-shaped bacteria containing four species that are differentiated by biochemical reactions: S. dysente´riae (subgroup A), S. flex´�neri (subgroup B), S. boy´dii (subgroup C), and S. son´nei (subgroup D). Their normal habitat is the intestinal tract of humans and higher monkeys; all species cause dysentery.

shigella

 [shĭ-gel´ah]
any individual organism of the genus Shigella.

Shigella

(shē-gel'lă),
A genus of nonmotile, aerobic to facultatively anaerobic bacteria (family Enterobacteriaceae) containing gram-negative nonencapsulated rods. These organisms cannot use citrate as a sole source of carbon; their growth is inhibited by potassium cyanide and their metabolism is fermentative; they ferment glucose and other carbohydrates with the production of acid but not gas; lactose is ordinarily not fermented, although it is sometimes slowly attacked; the normal habitat is the intestinal tract of humans and of higher apes; all of the species produce dysentery. The type species is Shigella dysenteriae.

Etymology: Kiyoshi Shiga, Japanese bacteriologist, 1870-1957
a genus of gram-negative pathogenic bacteria that causes gastroenteritis and bacterial dysentery, such as Shigella dysenteriae. It is also associated with hemolytic uremic syndromes. See also shigellosis.

Shigella

a genus of gram-negative rods in the family Enterobacteriaceae. There are four subgroups or species. The type species, S. dysenteriae, causes bacillary dysentery in humans and nonhuman primates. Other animals are resistant to infection, but organisms have been isolated from dogs without clinical signs.

Although our results suggest that shigellae with resistance to ciprofloxacin, ceftriaxone, or azithromycin circulate predominantly among MSM in the United States, these strains are likely to emerge among other populations.
Furthermore, many public health jurisdictions do not routinely perform PFGE on shigellae, making it difficult to detect clusters and, when a cluster is detected, to locate all cases associated with the cluster.

avicennoides showed more shigellocidal effect in terms of growth inhibition, MIC, and MBC than other extract preparations, and this suggests synergistic action of active principles in both the plants against shigellae.
