From a sample of non-treated, non chlorinated well water a Yersinia pseudotuberculosis II strain was isolated. The water had been apparently massively contaminated because the strain was isolated from 1 ml of the sample. The serotype II of Y. pseudotuberculosis occurs very rarely as aetiological agent of human and animal infections.
