Three types of illness have been reported:
·
In young children, it usually manifests as a self-limited
gastroenteritis or enterocolitis.
·
In older children, the illness takes the form of mesenteric
adenitis and inflammatory terminal ileitis which may mimic appendicitis.
·
The third type usually strikes adults, manifesting as
bacte-raemia, meningitis, arthralgia, or erythema nodosum. Complications
include intestinal perforation, peritonitis, and gangrene of small bowel.
Nausea, bloody diarrhoea, and
abdominal pain have been reported in patients following ingestion of
pasteurised milk contaminated with Yersinia
enterocolitica.
Iron loading can increase the
virulence of Y. enterocolitica.
Use of desferrioxamine can also
predispose to systemic infection.

technique of cold enrich- ment.

Culture of food, blood, skin
abscesses, pharyngeal swab, etc. Serologic examination of paired sera.
