Shigellosis is caused by four specific types of Shigella. [2] These are typically spread by exposure to infected feces. [1] This can occur via contaminated food, water, or hands or sexual contact. [1] [4] Contamination may be spread by flies or when changing diapers (nappies). [1] Diagnosis is by stool culture. [1]
The term is usually restricted to Shigella infections. [2] Shigellosis is caused by one of several types of Shigella bacteria. [3] Three species are associated with bacillary dysentery: Shigella sonnei, Shigella flexneri and Shigella dysenteriae. [4] A study in China indicated that Shigella flexneri 2a was the most common serotype. [5]
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 ...
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 epithelial cells and ...
Shiga toxins (Stxs), responsible for foodborne illnesses, are a classification of toxins produced by Shiga toxin-producing Escherichia coli (STEC) and Shigella dysenteriae serotype 1. Stx was first identified in S. dysenteriae and was later found to be produced by certain strains of E. coli. [8]
Shigella results in about 165 million cases of diarrhea and 1.1 million deaths a year with nearly all cases in the developing world. [5] In areas with poor sanitation nearly half of cases of diarrhea are due to Entamoeba histolytica. [6] Entamoeba histolytica affects millions of people and results in more than 55,000 deaths a year. [12]
Shiga toxin type 1 and type 2 (Stx-1 and 2) are the Shiga toxins produced by some E. coli strains. Stx-1 is identical to Stx of Shigella spp. or differs by only one amino acid. [6] Stx-2 shares 55% amino acid homology with Stx-1. [7] Cytotoxins – an archaic denotation for Stx – is used in a broad sense.
Gameknight experiences real-life adventures and actual danger with life-or-death consequences while stuck in the Minecraft digital universe.
