Q. Can you explain Yersinia Enterocolitica Gastroenteritis?
Yersiniosis  is  an  infectious disease caused by  a  bacterium of  the  genus  Yersinia. Most human illness is caused by one species, I: enterocolitica. It is a gram-negative.  Although normally its optimum growth temperature  is  about  32"C,  it  can grow  even  at  temperatures below 4°C.
The organism produces  an enterotoxin that survives  at  100°C for 20 minutes. The symptoms of the disease include severe abdominal pain, fever and diarrhoea which occur after 24 hours due to the consumption of the incriminated food. The abdominal pain  in this case  resembles that  of  'appendicitis'. The organism  is  found  in  the intestinal tract of several animals including pigs, cattle and dogs. I: enterocolitica has been isolated from dairy products, egg products, raw meats, poultry  and vegetables.
