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]
The cause of dysentery is usually the bacteria from genus Shigella, in which case it is known as shigellosis, or the amoeba Entamoeba histolytica; then it is called amoebiasis. [1] Other causes may include certain chemicals, other bacteria, other protozoa, or parasitic worms. [2] It may spread between people. [4]
Shigellosis, known historically 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 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 ...
In 2001 images of NCs from Shigella flexneri were digitally analyzed and averaged to obtain a first semi-3D structure of the NC. [8] The helical structure of NCs from Shigella flexneri was resolved at a resolution of 16 Å using X-ray fiber diffraction in 2003, [30] and a year later a 17-Å 3D structure of NCs from Salmonella typhimurium was ...
Shigella flexneri is a rod shaped, nonflagellar bacterium that relies on actin-based motility. It produces the protein actin in a swift and continuous fashion to propel itself forward within and between the host's cells. [4] This bacterium is gram-negative, non-spore forming Shigella from serogroup B. There are 6 serotypes within this serogroup.
Salmonella was discovered in six samples of Darwin’s Natural Pet Products’s raw dog food and listeria was found in one. Only about 3% of Darwin’s Natural customers are likely to be affected ...
Salmonellosis is a symptomatic infection caused by bacteria of the Salmonella type. [1] It is the most common disease to be known as food poisoning (though the name refers to food-borne illness in general), these are defined as diseases, usually either infectious or toxic in nature, caused by agents that enter the body through the ingestion of food.
