Abstract:
OBJECTIVE To investigate the antibiotics-resistant genes in enterococci isolated from the 98th Hospital of PLA,Huzhou,Zhejiang Province,China.METHODS The antibiotics-resistant genes of TEM,aac(6′)/aph(2″),aph(3′)-Ⅲ,ant(2″)-Ⅰ,ant(4′,4″),ant(6)-Ⅰ,ermB,mefA,tetM,vanA,and vanB were analyzed by polymerase chain reaction(PCR) and verified by DNA sequencing in the 15 isolates of Enterococcus faecalis and 9 isolates of E.faecium.RESULTS The positive rate of the resistance genes of TEM,aac(6′)/aph(2″),aph(3′)-Ⅲ,ant(2″)-Ⅰ,ant(4′,4″),ant(6)-Ⅰ,(ermB,) mefA,tetM,vanA,and vanB in the 24 strains of enterococci tested were 37.5%,70.8%,25.0%,0.0%,0.0%,41.7%,75.0%,0.0%,41.7%,4.2%,and 4.2%,(respectively.) CONCLUSIONS The multidrug resistance of enterococci was a serious issue,and harbored antibiotics-resistance genes were the very important reasons of resistance to antibiotics in enterococci.
