Listeria

 [lis-tēr´e-ah]
a genus of gram-positive bacteria (family Corynebacterium). L. monocyto´genes causes listeriosis.

Listeria

(lis-tēr'ē-ă),
A genus of aerobic to microaerophilic, motile, peritrichous bacteria containing small, coccoid, gram-positive rods; these organisms tend to produce chains of 3-5 cells and, in the rough state, elongated and filamentous forms. Cells 18-24 hours old may show a palisade arrangement with a few V or Y forms; the bacteria produce acid but no gas from glucose and are found in the feces of humans and other animals, on vegetation, and in silage and are parasitic on poikilothermic and warm-blooded animals, including humans. The type species is Listeria monocytogenes.

Listeria

a genus of gram-positive bacteria in the form of small rods which frequently resemble diphtheroids. The most important species, L. monocytogenes, is found chiefly in ruminants and can be divided into 16 serovars on the basis of somatic and flagellar antigens and there is considerable genetic diversity between serovars. Serovars 4b, 1/2a and 1/2b and 3 are most commonly isolated from diseased animals but there are geographical differences. It causes a multi-syndrome disease referred to as listeriosis. L. ivanovii causes abortion in cattle and sheep.
