Phage typing of Klebsiella strains in epidemiological studies.

A set of 14 routinely applied bacteriophages was used for the typing of Klebsiella pneumoniae and Klebsiella oxytoca strains isolated from patients in 1983-1986. The phage-sensitive strains (65%) differed in respect to the place and time of isolation which manifested itself by an occurrence of specific lysotypes in Wrocław, Gdańsk, Wernigerode and Włocławek, as well as various repeatibility on the lysotypes within 10 years.
