Salmonella species are widely distributed in other animals, frequently producing disease that can be transmitted to humans. In humans pathogenic species cause enteric fevers (typhoid fever and paratyphoid fever), septicemia, and gastroenteritis. The most frequent manifestation is food poisoning. Pathogenic species include S. arizo´nae (salmonellosis), S. cho´lerae-su´is (a strain pathogenic for pigs that may infect humans), S. enteri´tidis (gastroenteritis; also see discussion of Ewing scheme above), S. paraty´phi (or S. enteri´tidis serotype paraty´phi A) (paratyphoid fever), S. ty´phi (typhoid fever), and S. typhimu´rium (or S. enteri´tidis serotype typhimu´rium (food poisoning and paratyphoid fever).
Salmonella(sal'mō-nel'ă), Avoid the mispronunciation săm'ō-nel'la.
Salmonella/Sal·mo·nel·la/ (sal″mo-nel´ah) a genus of gram-negative bacteria. The genus Salmonella is very complex and has been described by several different systems of nomenclature. Clinical laboratories frequently report salmonellae as one of three species, differentiated on the basis of serologic and biochemical reactions: S. ty´phi, S. choleraesu´is, and S. enteri´tidis; the last contains all serotypes except the first two. In this system many strains familiarly named as species are designated as serotypes of S. enteritidis. Salmonellae may also be grouped into five subgenera (I–V) on the basis of biochemical reactions and further into species on the basis of antigenic reactions; subgenus I contains most of the species. Pathogenic species include S. arizo´nae (salmonellosis), S. choleraesuis (a strain pathogenic for pigs that may infect humans), S. enteritidis (gastroenteritis), S. enteritidis serotype paraty´phi A (paratyphoid fever), S. typhi (typhoid fever), and S. enteritidis serotype typhimu´rium (food poisoning and paratyphoid fever).
salmonella/sal·mo·nel·la/ (sal″mo-nel´ah) pl. salmonel´lae any organism of the genus Salmonella. salmonel´lal
SalmonellaA genus of bacteria containing over 2000 strains, no longer considered to be separate species. Some have species-specific infectivity. About half of the strains are known to cause FOOD POISONING in humans. Salmonella organisms also cause TYPHOID and PARATYPHOID fevers. Common contaminants of food include Salmonella typhimurium , S. hadar , S. enteritidis and S. virchow . (Daniel E. Salmon, American pathologist, 1850–1914)
Salmonellaa genus of bacteria containing a wide range of species that are pathogenic for man and other animals. They normally inhabit the intestinal tract. Examples include Salmonella typhi which causes typhoid fever and Salmonella typhimurium which causes severe gastroenteritis (salmonellosis).
