Shigella
Shigella is a genus of rod shaped, non-motile bacteria in the family of Enterobacteriaceae.[1][2] If it infects humans or other primates, causing the disease Shigellosis. This disease involves the bacterium replicating in the intestines and liver. Symptoms appear 2-3 days after infection and are characterized by intense and constant vomiting and diarrhea. Prognosis is poor and without intensive treatment with antibiotics and fluid replacement 20-30% of patients will die within a few days, mostly due to dehydration.[3] Chronic infection can cause liver abscesses and reactive arthritis. Even in the chronic phase attacks of vomiting and diarrhea can recur, especially due to immuno-suppression from HIV infection - which makes Shigellosis a common secondary infection of people suffering from AIDS in the developing world.
