ERYSIPELOTHRIX
(under the
microscope)
E. rhusiopathiae, the only species of this genus, is better
known as a veterinary pathogen than as a human pathogen. When cultured on blood
agar or some other nutrient medium, Erysipelothrix forms notably large
colonies. This ubiquitous microbe has been found in many farm animals such as
pigs, horses, and turkeys. Occasionaly, though, it can infect a human host and
cause an inflammatory skin disease, Erysipeloid. Treatment usually consists of
penicillin G, ampicillin, or cephalothin. Most clinical strains have been found
to be resistant to the super-antibiotic, vancomycin.
