ABSTRACT
Objective To investigate the genotype of klebsiella pneumonia strains isolated from eldly inpatients by multiple-locus variable-number tandem-repeat analysis. Methods Totally 184 klebsiella pneumonia strains,isolated from eldly inpatients,were collected,and their genome DNA were extracted. The polymorphism of 7 variable-number tandem-repeat locus in the DNA samples was analyzed by multiple primers polymerase chain reaction and capillary electrophoresis. The clustering analysis of genotyping was carried out with the BioNumerics 5.1 software. Results A total of 139 genotypes were identified in 184 klebsiella pneumonia clinical strains,showing obvious genetic polymorphisms. With clustering analysis of genotypes,all the strains were categorized into three gene clusters (genogroups 1,2,and 3). The genogroup 1 was the biggest cluster,containing 93.06% of the isolated strains. Conclusion There was a predominant cluster in the klebsiella pneumonia strains isolated from eldly inpatients in our center,and the major source of klebsiella pneumonia infection remained the nosocomial infection.
