Clonal dissemination of linezolid-resistant Staphylococcus haemolyticus exhibiting the G2576T mutation in the 23S rRNA gene in a tertiary care hospital in Brazil.
Linezolid, the first oxazolidinone class agent to be introduced clinically, has broad activity against many important multidrug-resistant Gram-positive pathogens, including methicillinresistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE). Linezolid inhibits protein synthesis by interacting with 23S rRNA in the 50S ribosomal subunit, and it should interfere with the b...
متن کاملClonal dissemination of linezolid-resistant Staphylococcus capitis with G2603T mutation in domain V of the 23S rRNA and the cfr gene at a tertiary care hospital in China
BACKGROUND The present study aims to investigate the potential mechanism of linezolid-resistant Staphylococcus capitis (LRSC) isolates collected from our hospital. METHODS The susceptibilities of 5 Staphylococcus capitis isolates displaying resistance towards linezolid were determined by E-test. Polymerase chain reactions (PCRs) and DNA sequencing were used to investigate the potential molecu...
متن کاملSequential linezolid-resistant Staphylococcus epidermidis isolates with G2576T mutation.
We report on an analysis of sequential isolates of Staphylococcus epidermidis from cultures of blood obtained from a patient with acute myeloid leukemia while the patient was receiving linezolid treatment. All 12 isolates had a linezolid MIC of 32 microg/ml. A 420-bp domain V region of the 23S rRNA gene from all isolates was amplified, and their nucleotide sequences were determined. A G2576T mu...
متن کاملComplete Genome Sequence of Linezolid-Susceptible Staphylococcus haemolyticus Sh29/312/L2, a Clonal Derivative of a Linezolid-Resistant Clinical Strain
We report the whole-genome sequence (WGS) of an in vitro susceptible derivative revertant mutant from a bloodstream isolate involved in a nosocomial outbreak in Brazil. The WGS comprises 2.5 Mb with 2,500 protein-coding sequences, 16rRNA genes, and 60 tRNA genes.
متن کاملMulticity outbreak of linezolid-resistant Staphylococcus epidermidis associated with clonal spread of a cfr-containing strain.
We report a multicity outbreak of cfr-containing linezolid-resistant Staphylococcus epidermidis in Ohio. Thirty-nine isolates were obtained from 2 hospitals. Two clones with different mechanisms of linezolid resistance were circulating in hospital A. One of these contained the cfr gene, and the other a ribosomal mutation. The clone containing cfr was identical in both hospitals.
