Phage-typing of Klebsiella strains from Cologne and Wroclaw.
276 strain of Klebsiella pneumoniae and Klebsiella oxytoca were phage-typed. 126 of these strains were isolated from clinical sources in the Institute of Hygiene in Cologne and 150 came from Wrocław. The set of 19 phages used for phage-typing was chosen out of 46 Klebsiella specific bacteriophages. 80% of the isolates from Cologne were sensitive to the phages in comparison to 83% of the strains from the Wrocław region. The phage sensitivity of the German strain differed from that of the Polish strains. 28 of the 67 phage-types were seen in Cologne and 35 in Wrocław, only 6 phage-types were observed in both regions. The frequency and the spectrum of the phage-types were different, too. Phage-types denoted by the numbers 1, 17, 32, 36, 37, 59, 64 appeared to be most frequent (10 to 16 strains). No significant differences in the sensitivity to typing phages between strains of Klebsiella pneumoniae and Klebsiella oxytoca were demonstrated.
