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.
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 ...
The organisms enter through the digestive tract and must be ingested in large numbers to cause disease in healthy adults. An infection can only begin after living salmonellae (not merely Salmonella-produced toxins) reach the gastrointestinal tract. Some of the microorganisms are killed in the stomach, while the surviving ones enter the small ...
Medically-relevant gram-negative diplococci include the four types that cause a sexually transmitted disease (Neisseria gonorrhoeae [15]), a meningitis (Neisseria meningitidis [16]), and respiratory symptoms (Moraxella catarrhalis, [17] A coccobacillus Haemophilus influenzae is another medically relevant coccal type. [18]
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]
Salmonella bongori was previously considered a subspecies of S. enterica, but it is now the other species in the genus Salmonella. Most of the human pathogenic Salmonella serovars belong to the enterica subspecies. These serogroups include S. Typhi, S. Enteritidis, S. Paratyphi, S. Typhimurium, and S. Choleraesuis.
Salmonella is a group of bacteria that can cause foodborne illness. It is commonly associated with undercooked meat and eggs; however, outbreaks have recently been linked to other foods, such as ...
Seizures occur most often in children, although how Shigella causes this complication is unknown. Bloodstream infections may occur from Shigella. Rectal prolapse can occur while straining during bowel movements. Toxic megacolon paralyzes bowel movements or causes passing gas. Reactive arthritis, which is the inflammation of joints [13]
