Characterization of coagulase-negative staphylococcal isolates from blood with reduced susceptibility to glycopeptides and therapeutic options
BACKGROUND Coagulase-negative staphylococci (CoNS) are a major cause of nosocomial blood stream infection, especially in critically ill and haematology patients. CoNS are usually multidrug-resistant and glycopeptide antibiotics have been to date considered the drugs of choice for treatment. The aim of this study was to characterize CoNS with reduced susceptibility to glycopeptides causing blood...
متن کاملComparison of genotypic and phenotypic methods for species identification of coagulase-negative staphylococcal isolates from blood cultures.
Coagulase-negative staphylococci are often isolated from blood cultures. Simple methods are needed for correct identification of those species most frequently found. In this study, PCR methods were developed for the identification of S. epidermidis and S. haemolyticus, based on DNA sequences in their 16S rDNA. The results obtained by these methods were compared with those obtained using a numbe...
متن کاملTetracycline resistance phenotypes and genotypes of coagulase-negative staphylococcal isolates from bubaline mastitis in Egypt
AIM This study was devoted to elucidate the tetracycline resistance of coagulase-negative staphylococci (CNS) derived from normal and subclinical mastitic (SCM) buffaloes' milk in Egypt. MATERIALS AND METHODS A total of 81 milk samples from 46 normal buffalo milk samples and 35 SCM buffalo milk samples at private dairy farms of Egypt were used in this study. CNS were identified using phenotyp...
متن کاملMacrolide-lincosamide-streptogramin resistance phenotypes and genotypes of coagulase-positive Staphylococcus aureus and coagulase-negative staphylococcal isolates from bovine mastitis
BACKGROUND There are limited data available on macrolide-lincosamide-streptogramin (MLS) resistance of Staphylococcus aureus (S. aureus) and coagulase-negative staphylococci (CoNS) from bovine milk in China. To address this knowledge gap, MLS resistance was determined in 121 S. aureus and 97 CoNS isolates. Minimum inhibitory concentrations (MICs) of MLS antibiotics were determined by an agar di...
متن کاملCharacterization of the translational attenuator of 20 methicillin-resistant, quinupristin/dalfopristin-resistant Staphylococcus aureus isolates with reduced susceptibility to glycopeptides.
Sir, Macrolide, lincosamide and streptogramin antibiotics are chemically distinct inhibitors of bacterial protein synthesis. Quinupristin/dalfopristin is a combination of streptogramin B and A compounds (SB/SA) with a synergic activity against most Gram-positive bacteria. Expression of MLS resistance in staphylococci may be constitutive or inducible. When expression is constitutive, the strains...
