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]
Pathogenic strains of Salmonella Typhi, Salmonella Paratyphi C, and Salmonella Dublin carry the capsular "Vi" antigen (Vi for virulence), [5] which is a special subtype of the capsule's K antigen (from the German word Kapsel meaning capsule).
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.
The outbreak strain could not be isolated from tomato samples from either of these farms, or any distributor that the CDC investigated. [ 2 ] From all of this, the CDC concluded that the major sources of contamination were jalapeño peppers and serrano peppers, while tomatoes may have been an additional source early in the outbreak.
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.
Salmonellosis annually causes, per CDC estimation, about 1.2 million illnesses, 23,000 hospitalizations, and 450 deaths in the United States every year. [1]The shell of the egg may be contaminated with Salmonella by feces or environment, or its interior (yolk) may be contaminated by penetration of the bacteria through the porous shell or from a hen whose infected ovaries contaminate the egg ...
Generating auxotrophic mutants (a strain of microorganism that will proliferate only when the medium is supplemented with some specific substance) that cannot replicate efficiently in an environment where a particular nutrient required by the mutant strain is scarce. Salmonella A1-R represents such a strain, which is auxotrophic for the amino ...
