Could coagulase negative staphylococci be an evolutionary source of resistance genes for Staphylococcus aureus?
Background The remarkable ability of Staphylococcus aureus to acquire mobile genetic elements that carry virulence and antibiotic resistance genes, contributes to its success, pathogenicity and evolution. There is indirect evidence that methicillinresistant S. aureus (MRSA) clones arose from genetic transfer of staphylococcal cassette chromosome mec (SCCmec) from Staphylococcus epidermidis and ...
متن کاملComparison of culture media for detecting methicillin resistance in Staphylococcus aureus and coagulase negative staphylococci.
The detection of methicillin resistance was examined in 51 strains of Staphylococcus aureus and 135 strains of coagulase negative staphylococci using Isosensitest, Diagnostic Sensitivity Test (DST), Mueller-Hinton (MH), Columbia, and Sensitest agars. MH agar with 5% added sodium chloride incubated at 35 degrees C was the most effective in detecting resistance in S aureus, and Columbia agar with...
متن کاملCharacterization of novel phages isolated in coagulase-negative staphylococci reveals evolutionary relationships with Staphylococcus aureus phages.
Despite increasing interest in coagulase-negative staphylococci (CoNS), little information is available about their bacteriophages. We isolated and sequenced three novel temperate Siphoviridae phages (StB12, StB27, and StB20) from the CoNS Staphylococcus hominis and S. capitis species. The genome sizes are around 40 kb, and open reading frames (ORFs) are arranged in functional modules encoding ...
متن کاملAntimicrobial Resistance Profile of Planktonic and Biofilm Cells of Staphylococcus aureus and Coagulase-Negative Staphylococci
The objective of the present study was to determine the antimicrobial resistance profile of planktonic and biofilm cells of Staphylococcus aureus and coagulase-negative staphylococci (CoNS). Two hundred Staphylococcus spp. strains were studied, including 50 S. aureus and 150 CoNS strains (50 S. epidermidis, 20 S. haemolyticus, 20 S. warneri, 20 S. hominis, 20 S. lugdunensis, and 20 S. saprophyt...
متن کاملEpidemiology of drug resistance: the case of Staphylococcus aureus and coagulase-negative staphylococci infections.
OBJECTIVE To study the activity of several antibiotics against Staphylococcus spp. MATERIAL AND METHODS The study included 1209 strains of Staphylococcus spp. from two institutions; Instituto Nacional de Pediatría (National Institute of Pediatrics) and Hospital Infantil de México Federico Gómez (Mexico City Children's Hospital). Minimum Inhibitory Concentrations of all antibiotics were determ...
