• Since 1989, a rapid increase in the incidence of infection and colonization with vancomycin-resistant enterococci (VRE) has been reported by U.S. hospitals. (cdc.gov)
  • This increase poses important problems, including a) the lack of available antimicrobial therapy for VRE infections, because most VRE are also resistant to drugs previously used to treat such infections (e.g., aminoglycosides and ampicillin), and b) the possibility that the vancomycin-resistant genes present in VRE can be transferred to other gram-positive microorganisms (e.g. (cdc.gov)
  • From 1989 through 1993, the percentage of nosocomial enterococcal infections reported to CDC's National Nosocomial Infections Surveillance (NNIS) system that were caused by vancomycin-resistant enterococci (VRE) increased from 0.3% to 7.9% (1). (cdc.gov)
  • INTRODUCTION From 1989 though 1993, the percentage of nosocomial enterococcal infections reported to the Centers for Disease Control and Prevention (CDC) National Nosocomial Infections Surveillance (NNIS) System that were caused by vancomycin-resistant enterococci (VRE) increased from 0.3% to 7.9%[1].

  • Although vancomycin resistance in clinical strains of S. epidermidis or S. aureus has not been reported, vancomycin-resistant strains of S. haemolyticus have been isolated[21,22]. (cdc.gov)

  • However, with the introduction and widespread use of both oxacillin and methicillin, antibiotic-resistant strains called methicillin-resistant and oxacillin-resistant Staphylococcus aureus (MRSA/ORSA) have become increasingly prevalent worldwide. (mdwiki.org)
  • This increase poses several problems, including a) the lack of available antimicrobials for therapy of infections caused by VRE, because most VRE are also resistant to multiple other drugs (e.g., aminoglycosides and ampicillin) previously used for the treatment of infections due to these organisms, and b) the possibility that the vancomycin resistance genes present in VRE may be transferred to other gram-positive microorganisms such as Staphylococcus aureus. (cdc.gov)
  • Members of the isoxazolyl penicillin family, which includes cloxacillin , dicloxacillin , and oxacillin, were synthesized to counter the increasing prevalence of infections caused by penicillin-resistant Staphylococcus aureus . (mdwiki.org)
  • Colistin , also known as polymyxin E , is an antibiotic used as a last-resort for multidrug-resistant Gram negative infections including pneumonia . (mdwiki.org)
  • Colistimethate sodium may be used to treat Pseudomonas aeruginosa infections in cystic fibrosis patients, and it has come into recent use for treating multidrug-resistant Acinetobacter infection, although resistant forms have been reported. (mdwiki.org)
  • The median minimal inhibitory concentrations of five of the 12 parenteral cephalosporins were lower with the methicillin-susceptible S. aureus than with the methicillin-susceptible S. epidermidis strains. (nih.gov)

  • The percentages of susceptibility of 28 strains of Campylobacter coli to beta-lactam agents were 96% for amoxicillin and ampicillin, 57% for ticarcillin, 4% for cefoxitin and cefuroxime, 61% for cefotaxime, and 11% for ceftazidime. (nih.gov)
  • Clavulanic acid (0.25 microgram/ml) but not sulbactam and tazobactam (2 micrograms/ml) lowered to susceptible levels the amoxicillin and ampicillin MICs of the only strain of C. coli resistant to amoxicillin, ampicillin, and ticarcillin. (nih.gov)
