Salmonella \Sal`mo*nel"la\, prop. n. [After Daniel E. Salmon, a
U. S. pathologist (1850-1914).]
A genus of gram-negative bacteria that may be motile or
non-motile; they are typically rod-shaped and may be aerobic
or facultatively aerobic. They may be pathogenic for humans
and other animals. Their metabolism is fermentative, and they
produce acid and usually gas from glucose, but they do not
metabolize lactose. The type species is Salmonella
cholerae-suis, which is found in pigs. Other species,
pathogenic in man, are Salmonella typhi (Salmonella
typhosa), Salmonella typhimurium, and Salmonella
schotmulleri, whih cause typhoid fever, food poisoning, and
enteric fever, respectively. --Stedman.
