Shigella
Shigella a genus of microorganisms of the family Enterobacteriaceae. It comprises different species of the causative agent of dysentery in monkeys and humans. They are gram-negative, nonmotile, nonspore-forming rods measuring 2–3 micrometers long and 0.6 micrometer wide. Aerobes and facultative anaerobes are distinguished. Shigellae form delicate semitransparent colonies on agar. They are subdivided into different types according to the colicins they secrete. Shigella
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.
