Genotyping research of methicillin resistant Staphylococcus aureus in nosocomial infection

Abstract

Abstract: Objective　To provide scientific referencefor controlling hospital acquired infection through analyzing the genotype homology of methicillin resistant Staphylococcus aureus（MRSA） which were isolated from different departments of hospital. Methods　The genotypes of 23 strains of hospital acquired MRSA were analyzed by repetitive polymerase chain reaction（REP-PCR） and DiversiLab genotype system. Results　Hospital acquired MRSA were classified into 4 kinds of genotypes（A，B，C and D）.A and D types were mainly distributed in Emergency Observation Room，while B and C types were mainly distributed in Traditional Chinese Medicine Surgery Department. Conclusions　B and C types may cause infection outbreak in Traditional Chinese Medicine Surgery Department as epidemic strains. REP-PCR and DiversiLab genotype system can be efficient ways for research of pathogen on nosocomial infection.
