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.
Salmonella species can be found in the digestive tracts of humans and animals, especially reptiles. Salmonella on the skin of reptiles or amphibians can be passed to people who handle the animals. [39] Food and water can also be contaminated with the bacteria if they come in contact with the feces of infected people or animals. [40]
Those infected usually develop symptoms anywhere from 12 to 72 hours after first contact with Salmonella bacteria, and most do not require serious medical attention. [8] This salmonellosis displays itself in humans with fever, abdominal pain, nausea, and, most commonly, diarrhea for a period of up to 7 days. [8]
Salmonella is a bacterium that can cause infection in both humans and animals. It typically leads to symptoms such as diarrhea, fever, and abdominal cramps in humans.
Salmonella causes about 1.35 million illnesses, 26,500 hospitalizations, and 420 deaths in the U.S. annually, according to the CDC. Contributing: James Powel and Ahjané Forbes
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.
These fevers occur following infection by Salmonella typhi and Salmonella paratyphi respectively. Rose spots may also occur following invasive non-typhoid salmonellosis. Rose spots are bacterial emboli to the skin and occur in approximately 1/3 of cases of typhoid fever. They are one of the classic signs of untreated disease, but can also be ...

Salmonella is a bacterium that produces the symptoms of diarrhoea, fever and abdominal cramps in infected individuals 12-72 hours after exposure. Most people recover without treatment and the illness usually lasts for 4-7 days.
