    Abstract:
    The taxonomy of Yersinia enterocolitica as well as their classification methods are still unreliable with respect to their pathogenicity. Therefore, a basis of evaluation was established by using extended biochemical tests (API-20-E, API-50-CH) and electrophoretic methods for identifying strains from human, food and water sources. All strains show great inhomogenicity, which was higher for non-human strains than for those isolated from clinical specimens. Thermophilic Campylobacters are especially prevalent in wild living fowl thus being a potential risk for surface water contamination. The results of the study show that high colony counts were found only during winter, whereas in summer the concentration lay below the infective dose. Furthermore, thermophilic Campylobacters were isolated only from samples that contained a higher number of fecal indicator organisms.
