Abstract:
OBJECTIVE To investigate Staphylococcus aureus(SAU)and coagulase-negative Staphylococcus(CNS)with continuously isolated virulence gene and drug-resistant genes status.METHODS We collected 100 SAU strains and 27 CNS strains,virulence gene(pvl)and drug-resistant genes(mecA,aac(6')/aph(2″),aph(3')-Ⅲ,ant(4',4″),ermA/B/C,msrA,tetM and qacA/B)were detected by PCR.RESULTS The positive rates of pvl,mecA,aac(6')/aph(2″),aph(3')-Ⅲ,ant(4',4″),ermA/B/C,msrA,tetM and qacA/B in MRSA were 11.6%,100.0%,94.2%,69.2%,2.9%,85.5%,85.5% and 46.4%.The positive rates of pvl,mecA,aac(6')/aph(2″),aph(3')-Ⅲ,ant(4',4″),ermA/B/C,msrA,tetM and qacA/B in MSSA were 74.2%,0%,9.7%,3.2%,0%,51.6%,9.7% and 0%,respectively.CONCLUSIONS There are very high positive percentages of mecA,aac(6')/aph(2″),aph(3')-Ⅲ,ermA/B/C,msrA,tetM and qacA/B genes in MRSA,and very high positive percentages of pvl and ermA/B/C genes in MSSA.
