[The search for Yersinia enterocolitica in vegetables treated by a cold line in school cafeterias in Montpellier].
From 134 samples of raw or cooked vegetables taken in two points of a cold line we isolated 19 strains of Yersinia enterocolitica, 3 of Y. intermedia 3 of Y. kristensenii. None of them belongs to serotypes usually pathogenic for man. The raw vegetables are most contaminated. Y. kristensenii and Y. intermedia were isolated especially from samples of green salad. The used method was a cold enrichment at 4 degrees C followed by a potassium hydroxyde treatment. The activity of 16 antimicrobial drugs was studied by the disk diffusion test at 28 degrees C. All strains were sensitive to aminoglycosides, minocycline, colistine and cotrimoxazole. The results obtained with chloramphenicol and beta-lactam antibiotics vary in terms of species and/or biotypes.
