Studies on Enterococci

Taxonomic Studies on the Enterococci *

Although the term "Enterococcus" appeared in bacteriological literature as early as 1899 (Thiercelin26) this bacterial group has yet to assume the position merited by its occurrence and by its distinctive characteristics. The fault lies primarily in the failure of workers to cover all phases in the study of their strains and in an inability to correlate the results of different studies, rather ...

Studies of cephalothin: aminoglycoside synergism against enterococci.

Combinations of cephalothin and aminoglycoside antibiotics are not currently used in the therapy of serious enterococcal infections, because clinical trials of these combinations have been unsuccessful. Studies of 28 enterococci isolated from patients with enterococcal bacteremia suggested three possible mechanisms for this in vivo antibiotic failure: (i) a relatively high level of resistance t...

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...

Virulence Factors in Enterococci

Enterococcus species were considered as non-pathogenic bacteria until recognized as an important cause of bacterial endocarditis in 1899. During the past decade, there has been a worldwide increase in occurrence of enterococcal infections. Though more than 28 enteroccocal species described, Enterococcus faecalis and Enterococcus faecium are isolated most frequently. This might be explained by t...
