A genus of aerobic to facultatively anaerobic bacteria (family Enterobacteriaceae) containing Gram-negative rods that are either motile or nonmotile; motile cells are peritrichous. These organisms do not liquefy gelatin or produce indole and vary in their production of hydrogen sulfide; they utilize citrate as a sole source of carbon; their metabolism is fermentative, producing acid and usually gas from glucose, but they do not attack lactose; most are aerogenic, but S. typhi never produces gas; they are pathogenic for humans and other animals. The type species is S. choleraesuis. [Daniel E. Salmon, U.S. pathologist, 1850–1914]
- S. enterica enteritidis a widely distributed bacterial species that occurs in humans and in domestic and wild animals, especially rodents; it causes human gastroenteritis.
- S. enterica paratyphi A a bacterial species that is an important etiologic agent of enteric fever in developing countries.
- S. enterica paratyphi B (formerly known as S. schottmülleri), consists of two distinct types of strains, those that produce enteric fever, found primarily in humans, and those producing gastroenteritis in humans, also found in animal species. This species includes 56 strains distinguishable by phage typing and/or biotyping, features of epidemiologic value.
- S. enterica typhi SYN: S. typhi.
- S. enterica typhimurium a bacterial species causing food poisoning in humans; it is a natural pathogen of all warm-blooded animals and is also found in snakes and pet turtles; worldwide, it is the most frequent cause of gastroenteritis due to S. enterica species.
- S. enterica choleraesuis a bacterial species that occurs in pigs, where it is an important secondary invader in the virus disease hog cholera, but does not occur as a natural pathogen in other animals; occasionally causes acute gastroenteritis and enteric fever in humans; it is the type species of the genus S..
- S. typhi the bacterial species that causes typhoid fever in humans; transmitted through ingestion of contaminated water or food. SYN: Eberth bacillus, S. enterica typhi, typhoid bacillus.
- S. typhosa former name for S. typhi.

1) cap a genus of aerobic gram-negative rod-shaped nonspore-forming usu. motile bacteria of the family Enterobacteriaceae that grow well on artificial media and form acid and gas on many carbohydrates but not on lactose, sucrose, or salicin, that are pathogenic for humans and other warm-blooded animals, and that cause food poisoning, acute gastrointestinal inflammation, typhoid fever, and septicemia
2) pl -nel·lae -'nel-ē or -nellas or -nella any bacterium of the genus Salmonella
Salm·on 'sam-ən Daniel Elmer (1850-1914)
American veterinarian. For the greater part of his career Salmon was associated with the U.S. Department of Agriculture, having joined the department to investigate diseases of domestic animals, especially Texas fever. He later founded and became chief of the Bureau of Animal Industry. In 1900 the genus Salmonella of bacteria was named after him.

a genus of motile rodlike Gram-negative bacteria that inhabit the intestines of animals and humans and cause disease. They ferment glucose, usually with the formation of gas. The species S. paratyphi causes paratyphoid fever, and S. typhi causes typhoid fever. Other species of Salmonella cause food poisoning, gastroenteritis, and septicaemia.

Sal·mo·nel·la (sal″mo-nelґə) [Daniel Elmer Salmon, American pathologist, 1850–1914] a genus of gram-negative bacteria of the family Enterobacteriaceae, consisting of non–spore-forming, facultatively anaerobic rods, usually motile with peritrichous flagella. The genus comprises two species, S. bongori and S. enterica, the latter containing six subspecies, and is separable into over 2400 serovars on the basis of O (somatic), Vi (capsular), and H (flagellar) antigens; O antigens are grouped into serogroups, of which six (A, B, C1, C2, D, and E) cause nearly all infections of warm-blooded animals. Pathogenic members are widely distributed in the animal kingdom and cause enteric fevers (typhoid and paratyphoid), septicemia, and gastroenteritis. In reporting Salmonella infections, the full taxonomic designation may be abbreviated, so that S. enterica subs. enterica serovar Typhi can become Salmonella serovar Typhi or Salmonella Typhi. The type species is S. enteґrica.
