Pathogenicity of Enterococci

Isolation rates and pathogenicity of enterococci in obstetric and gynecological operations.

Isolation of enterococci in patients undergoing obstetric and gynecological operations was studied as well as reviewing the postoperative infection due to this organism during the period from 1985 to 1990. 1) In 126 cases undergoing abdominal total hysterectomy, vaginal specimens were obtained before and after (3rd day) the operation. The isolation rates increased after the operation (before 16...

Molecular typing, pathogenicity factor genes and antimicrobial susceptibility of vancomycin resistant enterococci in Belgrade, Serbia.

In this study the distribution of species and antimicrobial resistance among vancomycin resistant enterococci (VRE) recovered from clinical specimens obtained from five hospitals in Belgrade was analyzed. Strains were further characterized by pulsed-field gel electrophoresis (PFGE). Polymerase chain reaction (PCR) was used to investigate the presence of vanA and vanB genes and pathogenicity fac...

Against Enterococci

Minimum inhibitory and bactericidal concentrations of four antibiotics and their combinations were determined for 38 strains of enterococci by a microtitration tube dilution technique. The drugs were ampicillin, vancomycin, gentamicin, and streptomycin; the combinations were ampicillin-gentamicin, ampicillin-streptomycin, vancomycin-gentamicin, and vancomycin-streptomycin. At achievable serum c...

Emergence of vancomycin-resistant enterococci.

Vancomycin and ampicillin resistance in clinical Enterococcus faecium strains has developed in the past decade. Failure to adhere to strict infection control to prevent the spread of these pathogens has been well established. New data implicate the use of specific classes of antimicrobial agents in the spread of vancomycin-resistant enterococci (VRE). Extended-spectrum cephalosporins and drugs ...
