Shigella causes disease in primates, but not in other mammals; it is the causative agent of human shigellosis. [2] It is only naturally found in humans and gorillas. [3] [4] During infection, it typically causes dysentery. [5]
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]
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]
Shigella flexneri is a species of Gram-negative bacteria in the genus Shigella that can cause diarrhea in humans. ... It has been found that chloramphenicol ...
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 ...
Shigellosis, also called shigella poisoning, is caused by shigella bacteria that affects the digestive system, according to the health department. Symptoms include a fever and diarrhea, which may ...
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.
In contrast, Shigella species may also produce shigella enterotoxins, which are the cause of dysentery. The toxin is effective against small blood vessels, such as found in the digestive tract, the kidney, and lungs, but not against large vessels such as the arteries or major veins.
