  Yersinia pestis - Wikipedia, the free encyclopedia
Yersinia pestis is a species of rod-shaped bacterium, belonging to the family Enterobacteriaceae.
The genus Yersinia is Gram negative, bipolar staining coccobacilli, and, similarly to other Enterobacteriaceae, it has a fermentative metabolism.
Among other things, these virulence factors are required for bacterial adhesion and injection of proteins into the host cell, invasion of bacteria into the host cell, and acquisition and binding of iron harvested from red blood cells.

That Yersinia enterocolitica, apparently, is not identified by the Great Smokies microbiology panel seems extremely important (23) given that Yersinia enterocolitica is associated with impaired monocyte function and with bacterial and fungal infections, including within mucosal surfaces, and often appearing during the first year of life (1-2, 5).
Yersinia, HHV6, and CMV are examples of pathogens that are more likely to be indentified by other testing processes -- eg, antibodies levels; and pathogens such as these are is very important because of their detrimental effects upon monocyte function and, thereby, their varied roles in allowing other infections to have greater effect.
Yersinia enterocolitica is an important enteric pathogen which has well-defined virulence determinants that allow the bacteria to become established in their hosts and overcome host defenses.
