Gram positive cocci mainly was Staphylococcus aureus and meticillin-resistant coagulase-negative staphylococcus (including Stayphylococcus haemolyticus and Staphylococcus epidermidis) and Enterococcus, Methicillin-resistant Staphylococcus Aureus (MRSA) accounted for 75.5% in 2002, 83.3% in 2003, and 89.7% in 2004, no Vancomycin-resistant Enterococcus (VRE) was found .
To obtain vancomycin-resistant Enterococci and Staphylococcus aureus, Enterococcus faecalis 458 and Staphylococcus aureus 9918 were mutagenized by the treatment of ultraviolet radiation and the most suitable time for the treatment was 30 s.
Multi-drug-resistant Gram-positive pathogens including methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococci (VRE) and Mycobacterium tuberculosis have become a serious problem in clinic.
Detection rates of high-level gentamycin resistance and high-level streptomycin resistance were 47.3% and 56.0% individually, the rate of vancomycin-resistant enterococci was 5. 3%.
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.
Objective:To investigate the distribution and the frequency of the high-level aminoglycosices and vancomycin resistance in clinical Enterococcus isolates, and to aid in the supervision of nosocomial infections, rational use of antibiotics clinically.
Objective To analyze postantibiotic effect (PAE) of heterogeneous vancomycin resistance Staphylococcus haemolyticus (h-VRSH) and study its influence on clinical therapy. Methods MIC,MBC and PAE of standard strain ATCC29213 and the clinical h-VRSH strain were analyzed by microdilution;
Drug re- sistance rate: penicillin 100 %, erythromycin 97. 22 %, ampicillin 95. 83 %, tetracycline 93. 06 %, oxacillin 83. 33 %. No strain was found to be resistant to vancomycin.
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.
corrodens strains were strictly anaerobic, cytochrome-oxidase-negative, urease-positive and gelatinase-positive; they were sensitive to lincomycin but resistant to vancomycin.
Enterococci belonging to various species resistant to vancomycin and related cyclic glycopeptide antibiotics have ben isolated from hospitalized patients in France, the UK and the USA.
