Wrażliwość szczepów Klebsiella pneumoniae na środki dezynfekcyjne
[Sensitivity of Klebsiella pneumoniae strains to the disinfectants]

J. Janowska

ABSTRACT

The sensitivity of 2 Klebsiella strains (isolated from hospital environment - Ks and museum - K28) to 7 disinfectants with the sensitivity of referent strain E. coli NCTC 8196 were compared. Suspension method was applied. Determined the sensitivity Klebsiella strains for phenol, septyl, lizol, chloraminę, formalin, glutaraldehyde and laurosept in compare with sensitivity of E. coli during 10 minutes of exposure. Certify the insignificant of difference in testing sensitivity of both Klebsiella strains on the majority disinfectants and more sensitive those strains than referent strain E. coli. In the case of chloraminę the difference was almost two fold - the value concentration ratio of the solutions giving bactericidal effect for E. coli in comparing the some concentration for Ks was 2.3. Only in the case of formalin the sensitivity of E. coli and Klebsiella pneumoniae was inverse - the value of concentration ratio was 0.51 - E. coli strain was 1.9 more sensitive than Ks strain and 1.6 more sensitive than K28 strain.
