Shigella sonneiRANK: SpeciesTAXONOMY: Bacteria -> Proteobacteria -> Gammaproteobacteria -> Enterobacteriales -> Enterobacteriaceae -> Shigella -> Shigella sonnei OVERVIEW: Shigella sonnei is a species of Shigella. Together with Shigella flexneri, it is responsible for 90% of shigellosis. Shigella sonnei is named for the Danish bacteriologist Carl Olaf Sonne. It is a Gram-negative, rod-shaped, nonmotile, nonspore forming bacterium. It can be grown on MAC agar and TSA, at 37°C optimally, but also grows at 25°C. It is facultatively anaerobic and chemoorganotrophic, and produces acid when carbohydrates are catabolized. Infections can result in acute fever, acute abdominal cramping, cramping rectal pain, nausea, watery diarrhea, or blood, mucus, or pus in the stool, which may occur within 1–7 days after coming in contact with the bacteria. This species has been identified as a resident in the human gastrointestinal tract based on the phylogenetic framework of its small subunit ribosomal RNA gene sequences.[PMC 4262072]
