Yer·sin·i·a pes·tis

a bacterial species causing plague in humans, rodents, and many other mammalian species and transmitted from rat to rat and from rat to humans by the rat flea, Xenopsylla; it is the type species of the genus Yersinia.

Yersinia pestis

Etymology: Alexandre E.J. Yersin; L, pestis, plague
a species of small gram-negative bacteria that causes plague. The primary host is the rat, but other small rodents also harbor the organism. A person without symptoms may be a carrier, but this happens rarely. Yersinia pestis is hardy, living for long periods in infected carcasses, the soil of the host's habitat, or sputum. Also called Pasteurella pestis. See also plague.

Yer·sin·i·a pes·tis

(yĕr-sin'ē-ă pes'tis)
A bacterial species that causes plague in humans, rodents, cats, and many other mammals; it is transmitted from rat to rat and from rat to human host by as many as 30 species of flea, including the rat flea Xenopsylla; the bacterium can also be transmitted by aerosol droplets dispersed by humans or animals (especially cats) manifesting a pneumonic form of plague, or by deliberate dissemination by means of an aerosol mechanism as a form of bioterrorism; the bacterium is the type species of the genus Yersinia.
Synonym(s): Kitasato bacillus.

Yersinia

a genus of ovoid or rod-shaped, nonencapsulated, gram-negative bacteria in the family Enterobacteriaceae.

Yersinia enterocolitica
often carried by many animal species, especially pigs, and associated with sporadic diarrhea in humans and animals. Farmed deer are highly susceptible.
Yersinia pestis
causes bubonic plague in humans and sylvatic plague in rodents and cats.
Yersinia pseudotuberculosis
causes yersiniosis in laboratory animals, wild rodents and domestic species, including cattle, sheep and cats. See also pyemic hepatitis.
Yersinia ruckeri
