MRSA and MRCNS accounted for 96.9% and 92.5% of Staphylococcus aureus and coagulase negative staphylococci,respectively. No vancomycin resistant strain of Staphylococcus spp.
No significant changes in vancomycin-resistant entrococci were found from 1999 to 2003.The prevalence of vancomycin-resistant enterococci (1999-2003) were 9.8%,7.7%,5.0%,4.1%,and 6.7% respectively.
Methicillin-resistant strains (MRSA and MRCNS) accounted for 65.3% of S.aureus (SA) and 70.7% of coagulase-negative staphylococci (CNS) respectively. No vancomycin-resistant (VRE) or -intermediate (VIE) strains were found in staphylococcus isolates.
Results 10 strains were vancomycin-resistant or intermediate to enterococci,5 strains were intrinsic resistance to vancomycin,5 strains were VRE(vanA for 1 strains,vanC1 for 4 strains,vanC2 for 3 strains,2 strains were unknown).
The transferability of the vancomycin resistance trait of the strains was examined by broth mating and filter mating. Results The vanA gene of 11 VanA type isolates of Enterococcus faecium were positive and the vanB gene of 1 VanB type isolate of Enterococcus faecalis was positive.
Conclusion In this study, all of VanA type vancomycin resistant Enterococci were Enterococcus faecium with vanA gene positive, and the VanA type vancomycin resistance can horizontal transfer between Enterococci.
Objective To investigate the molecule epidemic for 7 genes interrelated penicillin,erythromycin,tetracycline, vancomycin resistance of isolated Streptococcus pneumoniae(SP) in children at Suzhou area.
Objective Vancomycin resistance phenotypes and genotypes were studied for know the distribution of vancomycin resistant enterococci(VRE)in Renjin hospital and instruct rational application of antibiotics clinically.
The review shows the development in the prophylactics and therapy of methicillin (multi)-resistant Staphylococcus aureus (MRSA) and the lately emergenced vancomycin-resistant Staphylococcus aureus (VRSA) strains the lately emergenced.
Increased mortality is not uniformly shown for all of these organisms: Methicillin-resistantStaphylococcus aureus (MRSA) seems to cause significantly higher mortality, in contrast to vancomycin-resistant enterococci (VRE).
We report a case of linezolid-induced lactic acidosis during treatment of vancomycin-resistant enterococcal bacteremia after mitral valve replacement and permanent pacemaker implantation.
Vancomycin resistance in enterococci and methicillin resistance in Staphylococcus aureus have disseminated among hospitals, nursing homes and, in some cases, community patients.
