What is Yersinia?

Yersinia
Colonies of Y. enterocolitica grown on CIN agar and mVYE agar incubated at 30°C for 24 h. Yersinia colonies on CIN form the characteristic deep red center (“bull's eye”) with a transparent margin and diameter 2–4 mm. Pathogenic Y. enterocolitica serotype O:3/biotype 3 variant VP− (white arrow) forms red colonies and is easily differentiated from most nonpathogenic Yersinia organisms (black arrow) and other Gram-negative bacteria, which form dark-red colonies with a dark peripheral zone as a result of mannitol fermentation and esculin hydrolysis.

What is the Pathology of Yersinia Enterocolitica?

The pathology of yersinia enterocolitica is:

-Etiology: The cause of yersinia enterocolitica is bacteria Yersinia.

-Genes involved: None.

-Pathogenesis: The sequence of events that lead to yersinia enterocolitica are: colonization of the intestinal tract, particularly the distal small intestine terminal ileum and proximal colon. Accordingly, most of the pathologic effects and, hence, clinical manifestations occur at this location.

-Histology: The histology associated with yersinia enterocolitica shows bacteria.

How does Yersinia Enterocolitica Present?
