dissemination of a pscfs3-like cfr-carrying plasmid in staphylococcus aureus and staphylococcus epidermidis clinical isolates recovered from hospitals in ohio.nineteen linezolid-resistant staphylococcus epidermidis and two staphylococcus aureus isolates recovered from two medical institutions in northeast ohio and an s. aureus cfr index strain previously collected in the same facilities during the 2007 sentry antimicrobial surveillance program were investigated for the genetic basis of oxazolidinone resistance and the location of cfr. s. aureus isolates were typed by pulsed-field gel electrophoresis (pfge), spa typing, and multilocus sequence typing ( ...201323571552
the changing face of odontogenic infections.the purpose of this investigation was to compare characteristics of patients hospitalized with odontogenic infections during the 1980s to those of the 1990s.200111429732
heavy contamination of operating room air by penicillium species: identification of the source and attempts at decontamination.increased rates of nosocomial infection caused by filamentous fungi in immunocompromised patients prompted microbiologic surveillance of the central air handling systems in our hospital. during a 4-year period, penicillium species were isolated from 47 patients, including two with surgical wound infections caused by penicillium. counts of penicillium in operating room air were much higher (195 colony-forming units [cfu]/m3) than in 95% filtered corridor air (14.6 cfu/m3; p less than 0.01). venti ...19902135636
united states resistance surveillance results for linezolid (leader program for 2007).the leader program (2007) monitors for emerging linezolid resistance in sampled us medical centers, initiated in 2004. for the current reported year, the number of sites participating was increased from 50 to 60 institutions representing all 9 us census regions with 100 target organisms per site (6305 isolates, 105.1% compliance to protocol design). the organisms tested by reference broth microdilution methods were staphylococcus aureus (3318), coagulase negative staphylococci (cons, 1020), ente ...200819022153
multicity 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.201020726771
