Enteral yersiniosis is caused either by Y. enterocolitica 0-group I (syn. serotype 0:3) and 0-group V (syn. serotype 0:9) or Y. pseudotuberculosis type I-VI. The clinical symptoms are mostly like enteritis, enterocolitis, acute abdomen, mesenteric lymphadenitis, or ileitis terminalis. Post-infection reactions are possible like septicemia, arthritis and erythema nodosum. Only cultural and serological examinations confirm the diagnosis of enteral yersiniosis. In the judgement of serological results it is necessary to consider the cross-reactions of Y. enterocolitica 0-group V to Brucella abortus, Brucella melitensis and Brucella suis and also to the antigenic community of Y. pseudotuberculosis type II respectively IV to Salmonella group B respectively D. With exception of septicemia, it is not necessary to treat enteral yersiniosis with antibiotics.

Twenty-four patients with homozygous beta-thalassaemia who had been splenectomised and currently on treatment were studied retrospectively. They were divided into two groups. Group A: who had splenectomy prior to commencement of any regular blood transfusion. The mean haemoglobin for this group rose from 5.5 gm/dl pre-splenectomy to 7.7 gm/dl post splenectomy (p < 0.001). Group B: who were on regular blood transfusion when they had their splenectomy and the mean blood transfusion requirement dropped from 317 ml/kg/yr to 230 ml/kg/yr of packed red cells following splenectomy (p < 0.001). Three patients who were on regular blood transfusion and desferrioxamine developed Yersinia enterocolitica infection. They presented with fever and signs of an acute abdomen. At laparotomy, 2 of the patients had acute appendicitis. All 3 appendices grew Yersinia enterocolitica and one patient also had a Yersinia enterocolitica septicaemia. If a patient develops fever and enteritis, desferrioxamine should be stopped temporarily and cotrimoxazole started as prophylaxis against systemic Yersiniosis. No cases of pneumoccocal sepsis was reported.

Yersinia enteritis may present with alarming gastrointestinal manifestations. The aim of this study was to review the cases of children admitted to a general hospital with a preliminary diagnosis of surgical nature and subsequently proven to be infected by Yersinia enterocolitica. All cases of children aged less than 14 years with stool cultures positive for Y. enterocolitica during the 12-year period January 1993 through December 2004 were analyzed. Y. enterocolitica was isolated from the stools of 71 children with gastrointestinal manifestations; 27 children were treated as outpatients and 44 were hospitalized. Six were admitted to the Pediatric Surgery Department (13.6% of the total hospitalizations and 8.4% of all Y. enterocolitica cases). Four of the Pediatric Surgery patients presented with abdominal pain and right lower quadrant tenderness. The preliminary diagnosis of appendicitis was excluded during hospitalization and none of them underwent appendectomy. The other two children were admitted for vomiting initially attributed to a preceding head injury and for diarrhea and a perianal abscess. Two children were given antibiotics and all had an excellent outcome. Y. enterocolitica enteritis manifestations can infrequently mimic appendicitis or other surgical conditions but should remain in the differential diagnosis of children presenting with an acute abdomen.
