Listeria monocytogenes isolated from wapiti (Cervus canadensis roosevelti)

Abstract

Serotypes 1 and 4 Listeria monocytogenes were isolated from 14 of 72 wapiti among four of five herds studied in northwestern California. More isolations of Listeria were made during the summer months than during the other months of the study from one of the herds. The pathogenicity of the strains varied with their ability to ferment xylose and rhamnose.
