Abstract


Germs from Yersinia genus have a vast ecologic niche, being met at different domestic and wild animal species, but also in food, water and soil. The majority of yersinis live in the digestive tract of human and numerous animal species, especially rodents, but also in soil, plant debris, waters etc. Numerous species of Yersinia genus could produce characteristic infections in human, the main source of infections is represented by rodents and hematophagous insects or, more frequently, by water or contaminated food. In a 1999 study, Mead and coauthors established that the Yersinia enterocolitica prevalence in food, in USA, is around 90%. Foods of animal origin more frequently contaminated with Yersinia enterocolitica are: pork, poultry, beef and lamb meat, milk, ice-cream, sea fruits etc., among them pork meat and milk represents the sources of the most numerous toxi-infection outbreaks in human, in different world regions. Bacteria determine infections which interest the digestive tract in numerous animal species and human, with diarrhea, lymphadenitis, pneumonia and abortion are the most important symptoms. Yersinia enterocolitica enter the human body regularly by oral ingestion, and localize itself with predilection in the distal portion of the ileum and at the ileocaecal appendix and proximal colon level, were determine a terminal ileitis with lymphadenitis, acute enterocolitis, and secondary accompanied with nodosum erythema, poliartritis that could be complicated with septicemia, sometimes leading to death.
