The oxazolidinone antimicrobial, linezolid, has been approved for the treatment of infections caused by various gram-positive bacteria, including vancomycin-resistant enterococci (VRE). This is the first report on isolation of a linezolid resistant, vancomycin-resistant Enterococcus faecium (LRVREF) strain in Poland, from a Haematological Unit patient in the Clinical Hospital in Gdańsk. PCR-RFLP analysis...
Enterococcal infection has become a major clinical problem and E. faecalis and E. faecium are the most frequently isolated species. However, the isolation of other species (E. casseliflavus, E. gallinarwn, E. durans) from clinical materials was reported recently. The aim of this study was to evaluate drug resistance of 97 species of enterococci isolated from clinical specimens of Upper Silesian Health...
A number of Enterococcus strains with high-level inducible resistance to vancomycin have been identified, and the relative incidence of these strains has increased significantly in the last years. The first outbreak caused by vancomycin-resistant enterococci in Poland was reported in 1999. Vancomycin-resistant Enterococcus faecium is known for its propensity to cause infections which are difficult...
The prevalence of glycopeptides, aminoglycosides and erythromycin resistance among Enterococcus faecalis and Enterococcus faecium was investigated. The susceptibility of 326 enterococcal hospital isolates to amikacin, kanamycin, netilmicin and tobramycin were determined using disk diffusion method. The minimum inhibitory concentration (MIC) of vancomycin, teicoplanin, gentamicin, streptomycin, and...
Pheromone-responsive plasmids constitute a unique group of ~ 20 plasmids identified, as yet, only among enterococcal species. Several of their representatives, e.g. pAD1, pCF10, pPD1 and pAM373 have been extensively studied. These plasmids posses a sophisticated conjugation mechanism based on response to sex pheromones - small peptides produced by plasmid-free recipient cells. Detailed analysis of...
Enterococcus faecalis and Enterococcus faecium are among the main agents associated with nosocomial infections with high mortality in immunocompromised patients. Antibiotic resistance, especially against gentamicin and vancomycin among Enterococci, is a risk factor that could increase the morbidity and mortality rate. 179 Enterococci isolates from burn patients were included in this study. Antibiotic...
