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]
They are also nearly everywhere in the environment and, although normally invisible, can form slimy biofilms. [3] Extremophiles have adapted to live in some of the most extreme environments on Earth. This includes hypersaline lakes, arid regions, deep sea, acidic sites, cold and dry polar regions and permafrost. [4]
The other less fit strains will be selected against and will thus not persist. Another major host adaptation on the part of Salmonella was its adaptation to host blood temperatures. Because Salmonella can thrive at the human host temperature, 98.6 degrees F, it is fit for the host environment and hence survives well in it.
Salmonella, a bacteria found in the intestines of animals and humans, can cause symptoms like diarrhea, fever, and stomach cramps and is a leading cause of foodborne illness in Europe.
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 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 ...
But certain bacteria can be helpful in preventing disease, not causing it. For example, consuming probiotics, or beneficial bacteria, to improve gut health has risen in popularity in recent years ...
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.
