Abstract:
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.
Insights
Bacteriophage typing of Klebsiella pneumoniae and Klebsiella oxytoca revealed distinct lysotypes specific to different locations and time periods between 1983-1986. This study highlights geographic and temporal variations in these bacterial strains.
Area of Science:
- Microbiology
- Bacteriology
- Epidemiology
Background:
- Klebsiella pneumoniae and Klebsiella oxytoca are significant opportunistic pathogens.
- Bacteriophage typing is a method for differentiating bacterial strains.
- Understanding strain diversity is crucial for infection control.
Purpose of the Study:
- To characterize Klebsiella pneumoniae and Klebsiella oxytoca strains using bacteriophage typing.
- To investigate geographic and temporal variations in lysotypes.
Main Methods:
- Utilized a set of 14 routinely applied bacteriophages.
- Performed phage typing on Klebsiella strains isolated from patients between 1983 and 1986.
- Analyzed strain sensitivity and lysotype distribution.
Main Results:
- 65% of isolated strains were sensitive to the applied bacteriophages.
- Distinct lysotypes were identified in Wrocław, Gdańsk, Wernigerode, and Włocławek.
- Lysotype patterns showed variations over the 10-year study period.
Conclusions:
- Bacteriophage typing effectively differentiated Klebsiella strains.
- Geographic location and isolation time influenced the occurrence of specific lysotypes.
- The findings provide insights into the epidemiology of Klebsiella infections.
