One hundred methicillin-resistant Staphylococcus aureus (MRSA) strains, isolated between 1983 and 1999, were tested alongside the vancomycin hetero-resistant S. aureus (hVRSA) strain Mu 3, and vancomycin-resistant S. aureus (VRSA) strain Mu 50, for their resistance to vancomycin. This was achieved using the screening method described by Hiramatsu, gradient plates, agar incorporation, standard E...

The increasing incidence of Vancomycin resistant Enterococcci (VRE) infection is of concern because of limited treatment options and increased mortality. Here we report a rare case of Vancomycin resistant Enterococccal neonatal sepsis. A Very low birth weight male neonate with respiratory distress and suspected hyaline membrane disease was admitted to NICU had pulmonary haemorrhagia and suspect...

BACKGROUND Most cases of reduced vancomycin susceptibility in Staphylococcus aureus reported in the literature have been in methicillin-resistant strains. We report the development of reduced vancomycin susceptibility in a series of clonally related, methicillin-susceptible S. aureus (MSSA) clinical isolates. This isogenic series permitted us to determine whether the evolution of reduced vancom...

Enterococci cause serious illness in immunocompromised patients and severely ill, hospitalized patients. Resistance to vancomycin has increased in frequency during the past few years. Limited therapeutic options are available for vancomycin-resistant enterococcal infections and the optimum therapy has not been established. We report a case of nosocomial vancomycin-resistant Enterococcus faecium...

Two methicillin- and vancomycin-resistant Staphylococcus aureus strains, MI-VRSA and PA-VRSA, and Enterococcus faecalis DMC83006B, considered to be the potential donor of glycopeptide resistance to MI-VRSA, were studied. MI-VRSA is highly resistant to both glycopeptides, whereas PA-VRSA displays low-level resistance to vancomycin and reduced susceptibility to teicoplanin. We have analyzed the e...

We investigated the frequency of antibiotic resistance of Enterobacteriaceae and the presence of vancomycinresistance genes in samples taken from the Sea of Marmara, and the Istanbul and Canakkale Straits, Turkey. Di erent colony-forming bacteria were isolated and identi ed with the VITEK 2 Compact 30 system. e antibiotic resistance of the isolates was determined by the disc di usion method. e ...

conclusions the results of the current study designate the important role of medical samples as reservoirs of resistance inducing elements. early detection of vre with their virulence trait will help to prevent the spread of vancomycin resistant enterococcus species. supervision for antibiotic usage in hospitals, especially for last option antibiotics, can prevent the spread of resistant isolat...

OBJECTIVE To document the risk of the development of vancomycin-resistant bacteria in a population of seriously burned patients during a 10-year period of common vancomycin hydrochloride use. DESIGN Retrospective study. SETTING The US Army Institute of Surgical Research, Burn Center, Fort Sam Houston, Tex. POPULATION AND METHODS Microbiology, infection, and antibiotic use records collecte...
