Direct isolation of Yersinia enterocolitica and Yersinia pseudotuberculosis from meat. 1985

H Fukushima

Studies were done to determine the usefulness of dilute alkali (KOH) treatment of meat samples for direct isolation of Yersinia enterocolitica and Yersinia pseudotuberculosis, without enrichment. Virulent Y. enterocolitica and Y. pseudotuberculosis in pork contaminated with 10(2), 10(3), and 10(4) cells per g survived the direct KOH treatment and were never recovered by using KOH postenrichment treatment. From 6 (4.8%) of 125 samples of retail ground pork, four biotype 4 serotype O3 and one biotype 3B serotype O3 strains of Y. enterocolitica and one Y. pseudotuberculosis serotype 4b strain were recovered by using direct KOH treatment without enrichment. As these isolations were attained without using enrichment cultural procedures, they represent an important time-saving alternative to simplify and speed isolation of Yersinia spp. from meat.
