Shigella is a genus of bacteria that is Gram negative, facultatively anaerobic, non–spore-forming, nonmotile, rod shaped, and is genetically nested within Escherichia. The genus is named after Kiyoshi Shiga, who discovered it in 1897. [1] Shigella causes disease in primates, but not in other mammals; it is the causative agent of human ...
Shigellosis (Historically the disease usually referred to as Dysentery) is an infection of the intestines caused by Shigella bacteria. [1][3] Symptoms generally start one to two days after exposure and include diarrhea, fever, abdominal pain, and feeling the need to pass stools even when the bowels are empty. [1]
Dysentery may also be caused by shigellosis, an infection by bacteria of the genus Shigella, and is then known as bacillary dysentery (or Marlow syndrome). The term bacillary dysentery etymologically might seem to refer to any dysentery caused by any bacilliform bacteria, but its meaning is restricted by convention to Shigella dysentery.
A shigella infection can cause bloody diarrhea, fever and stomach pain, among other symptoms, making this an illness no one wants to have.
Shigella, which can spread through contaminated food or close contact with an infected person, typically causes symptoms one to two days after exposure. The illness usually lasts five to seven ...
Shiga toxins are a family of related toxins with two major groups, Stx1 and Stx2, expressed by genes considered to be part of the genome of lambdoid prophages. [1] The toxins are named after Kiyoshi Shiga, who first described the bacterial origin of dysentery caused by Shigella dysenteriae. [2] Shiga-like toxin (SLT) is a historical term for ...
Shigella dysenteriae. Shigella dysenteriae is a species of the rod-shaped bacterial genus Shigella. [1] Shigella species can cause shigellosis (bacillary dysentery). Shigellae are Gram-negative, non-spore-forming, facultatively anaerobic, nonmotile bacteria. [2] S. dysenteriae has the ability to invade and replicate in various species of ...
Bacterium sonnei Levine 1920. Shigella sonnei is a species of Shigella. [2] Together with Shigella flexneri, it is responsible for 90% of shigellosis cases. [3] Shigella sonnei is named for the Danish bacteriologist Carl Olaf Sonne. [4][5] It is a Gram-negative, rod-shaped, nonmotile, non-spore-forming bacterium. [6]
