Infections due to biochemically typical Yersinia enterocolitica usually present as gastroenteritis, mesenteric lymphadenitis, terminal ileitis, and septicemia often with visceral abscesses. In these instances, the isolates have been biochemically typical and of well-established serotypes, namely 0:3 or 0:9 and, in the United States, 0:5 or 0:8. The recovery, recognition, and significance of biochemically and serologically atypical Y. enterocolitica in human infections has proceeded more slowly. From an analysis of the clinical histories of 20 patients infected with 21 such aberrant Y. enterocolitica, it appears that these strains are of restricted pathogenic potential, producing various clinical entities such as localized skin abscesses, conjunctivitis, self-limiting enteritis, and wound and urinary tract infections in hosts with predisposing factors. Epidemiologically, whereas episodic acquisition of atypical strains by hospitalized patients is indicative of nosocomial transmission, in the present series sporadic isolations over a 4-year period, mainly from ambulatory patients, suggest an occult reservoir in the community serviced by The Mount Sinai Hospital. In contrast to typical Y. enterocolitica, which has become well adapted in animal and human hosts, it appears that environmental strains may be in the evolutionary process of becoming adapted to humans.

Y. enterocolitica has been shown to be a fairly common human pathogen in many countries. The clinical picture produced by Y. enterocolitica infections is quite variable. An acute abdominal disease (acute gastroenteritis or colitis, or a pseudoappendicitis due to acute terminal ileitis) and, less commonly, erythema nodosum and arthritis are the most important manifestations of the disease. On radiologic examination mucosal lesions of the terminal ileum are found in most patients with gastrointestinal symptoms. The colon is less frequently involved. The most typical lesions consist of shallow, small, round ulcers characteristic of the disease. Microscopic examination may suggest yersiniosis but does not show pathogenic signs. Y. enterocolitica can be detected by stool cultures or by serologic examinations. The disease is usually mild. If specific therapy is indicated the disease usually responds well to antibiotic therapy.

In the first year after establishing a gastroenterological center in a vineyard and industrial district with 220.000 inhabitants we examined 1.171 patients. In 36.53% we had diseases in the lower gastrointestinal tract excluding proctological disturbances. We could find out 37 cases of colitis ulcerosa and 42 colorectal cancers. Excluding two cancers in colon transversum and ascendens all the tumors were found by coloscopy. Previously 4 cases of colitis ulcerosa were identified by other methods, clinically or by rectoscopy. In 48.6% of the colitis ulcerosa the transfer was done by reason of blood in the feces. The melaena lingers between 1 month and 10 years. Other presumed diagnoses for transfer to our Institute were gastroenteritis, proctitis, hemorrhoids, fissure or ileitis terminalis Crohn. In some rare cases the supposed diagnosis was salmonellosis or mycosis of the intestinum. In colorectal cancers the main reason for special gastroenterological investigation was the addition of blood to stool, whether microscopically or visible. Abdominal pain or ileus were following in frequency. Clinical symptoms were to be reconstructed in 30.9% for six weeks, in 59% for six months and in 9.5% up to one year. Most of the colorectal tumors (85.7%) were localized distal from splenic colonflexur, mostly in the rectosigmoid and colon descendens (see figure 1). Ambulant coloscopy is a method for quickly and definitive clarification, if the practitioner will refer swiftly.

Yersinia enterocolitica is a zoonotic gram-negative pathogen that causes mesenteric lymphadenitis, terminal ileitis, acute gastroenteritis, and septicemia in domestic animals and primates. In 2012, 46 captive African green monkeys (Chlorocebus aethiops sabaeus) died during an outbreak of acutely fatal enteric disease over a period of 1 mo on the island of St Kitts. The affected monkeys presented with a history of mucohemorrhagic diarrhea, marked dehydration, and depression. Fifteen bacterial isolates were recovered from the spleen, liver, and lungs of affected monkeys. All isolates were identified as Y. enterocolitica by biochemical analysis and sequence comparison of the 16S rRNA gene. Phenotypic and genotypic analysis of the recovered isolates revealed homogeneity among the recovered bacteria, and all isolates gave a random amplified polymorphic DNA pattern resembling that given by genotype D under serotypes O:7,8. This outbreak represents the first isolation and characterization of Y. enterocolitica as the causative agent of fatal enteric disease in primates in the Caribbean.

Amatoxin poisoning is still associated with a great potential for complications and a high mortality. While the occurrence of acute gastroenteritis within the first 24 hours after amatoxin ingestion is well described, only very few descriptions of late gastrointestinal complications of amatoxin poisoning exist worldwide. We present the case of a 57-year-old female patient with severe amatoxin poisoning causing fulminant but reversible hepatic failure that on day 8 after mushroom ingestion developed severe abdominal pain and watery diarrhea. Ulcerating ileocolitis was identified by computed tomography identifying a thickening of the bowel wall of the entire ileum and biopsies taken from the ileum and large bowel revealing distinct ileitis and proximally accentuated colitis. The absence of discernible alternative etiologies such as infectious agents makes a causal relationship between the ulcerating ileocolitis and the amatoxin poisoning likely. Diarrhea and varying abdominal pain persisted over several weeks and clinical follow-up after six months showed a completely symptom-free patient. The case presented highlights the importance to consider the possibility of rare complications of Amanita intoxication in order to be able to respond to them early and adequately.
