  Yersinosis
The two sub-types that are responsible for yersinosis are Yersinia enterocolitica and Yersinia pseudotuberculosis.
The name Yersinia comes from Dr. Alexandre Yersin, who was the first person to grow a much more deadly type of Yersinia known as Yersinia pestis, the bacteria responsible for what is now known as bubonic plague.
Yersinia are classified as gram-negative bacteria (bacteria that do not accept the color of a stain in a Gram stain test, which indicates the general chemical nature of the cell wall of the bacteria); they have a variety of appearances, and are therefore called pleomorphic.

Cold foods should also be kept colder than the danger zone, below 5 °C (41 °F).
However, Listeria monocytogenes and Yersinia enterocolitica can both grow at refrigerator temperatures.
Hot foods should be held at 57°C (135 °F) or hotter until ready to cool.

Yersinia pseudotuberculosis is far less common in humans than in animals however it is transmitted the same oral way as does Yersinia enterocolitica. 
Figure 1 - Yersinia enterocolitica using Flagella staining is demonstrated here.
Culture of the organisms would reveal a Gram-negative enteric bacteria and can be obtained from lymph nodes, stool or even blood.  A serum agglutinin titer of 1:128 or greater is suggestive however absence of this finding does not rule out the infection in infants and immunocompromised individuals.
