The role of Yersinia enterocolitica as a human pathogen has been documented in publications from over 30 countries, and Y. enterocolitica has been recognized increasingly to cause gastrointestinal disease in children. In 1979, an Australian survey yielded only three isolates of Y. enterocolitica from 3298 faecal specimens obtained from adults. We screened all stool specimens received during a 22-month period for Yersinia by means of a recently developed selective agar medium. Y. enterocolitica was isolated from 32 of 4136 (0.7%) specimens. Most isolates were of serotype O:3, biotype 4. During the study, 154 Salmonella spp. (3.7%), 196 Campylobacter spp. (47%), seven Shigella spp. (0.2%) and 27 Aeromonas spp. (0.9% of 2779) were recovered. Children infected with Y. enterocolitica presented with acute diarrhoea associated with fever and pharyngitis; chronic or recurrent diarrhoea; or pain in the right iliac fossa associated with mesenteric adenitis. Gastrointestinal symptoms usually resolved spontaneously within two weeks. However, some children were treated successfully with cotrimoxazole.

Yersinia enterocolitica infection presents a wide clinical spectrum; in infants and young children it usually presents as uncomplicated acute diarrhea, while in older children and adolescents it more frequently presents as terminal ileitis and/or mesenteric adenitis. We describe two infants who developed terminal ileitis complicating Y. enterocolitica infection, which is exceptionally rare. The clinical, laboratory and radiologic findings are described and ultrasound study is emphasized as a simple and reliable tool for investigation of terminal ileitis.

Yersinia enterocolitica, an important food- and water-borne enteropathogen causes acute diarrhea, terminal ileitis, and mesenteric lymphadenitis. It is represented by six biovars (1A, 1B, 2-5). The biovar 1A strains are generally regarded as avirulent as they lack pYV plasmid and major chromosomal virulence genes. Despite this, some biovar 1A strains produce disease symptoms indistinguishable from that produced by known pathogenic biovars (1B, 2-5). Suggested prospective studies to understand pathogenic potential of biovar 1A should focus on role of insecticidal toxins, urease, protease, superoxide dismutase, and host responses. These studies should also take into account the clonal groups of biovar 1A.
