Growth of Yersinia enterocolitica strains representing serogroups O: 3, O: 5, 27, O:6, 30, O:8, O:9 (human isolates) and O:6, 31 (food isolate) were inhibited in the presence of a bacteriocin produced by Yersinia kristensenii at high initial cell count of 10 6 ml ‐1 . Complete (100%) inactivation of most Y. enterocolitica cells of different serotypes was observed within 24 h at low initial cell counts of 10 4 ml ‐1. Complete injury of the cells was observed within 4–8 h, with all the serotypes at 10°C and 28°C. The degree of susceptibility to the injury and the recovery of cells from the injury varied from serogroup to serogroup.
