Studies on bacteriocin production and sensitivity of Klebiella strains using the Abbott-Shannon sets of standard strains.

In the present study, the bacteriocin production of 308 Klebsiella strains and bacteriocin sensitivity of 131 Klebsiella strains were investigated by help of the two Abbott and Shannon sets of standard strains for colicin typing of Shigella sonnei. 63% of Klebsiella strains were found to be bacteriocin producers. Although a certain bacteriocin production pattern was predominant in 8 of 11 outbreaks studied it could not be demonstrated that this marker could confer any epidemiological relationship among the strains of the same focus. 70% of Klebsiella strains were colicin sensitive. Three different patterns of colicin sensitivity were described and one of them was predominant (in 89% of cases). Three different patterns of colicin sensitivity were described and one of them was predominant (in 89% of cases). Some particular aspects of colicin sensitivity in strains isolated from 2 subjects of the same focus are pointed out and the significance of this market for epidemiologicala strains were colicin sensitive. Three different patterns of colicin sensitivity were described and one of them was predominant (in 89% of cases). Some particular aspects of colicin sensitivity in strains isolated from 2 subjects of the same focus are pointed out and the significance of this market for epidemiological studies is discussed.
