Spontaneous staphylococcal cassette chromosome mec element excision in Staphylococcus aureus nasal carriers.
Among 23 patients carrying methicillin-resistant Staphylococcus aureus (MRSA) in their anterior nares, 6 (26%) also carried methicillin-susceptible S. aureus (MSSA) as less prevalent flora. In 4 of the 6 patients, the MSSA was unrelated to prevalent MRSA, as determined by pulsed-field gel electrophoresis (PFGE), multilocus sequence typing (MLST), and staphylococcal protein A (spa) typing. Howev...
متن کاملCharacterization of Staphylococcal Cassette Chromosome Mec Elements in Biofilm-producing Staphylococcus Aureus, Isolated from Hospital Infections in Isfahan
Background and Aims: Staphylococcus aureus is one of the important pathogens around the world. The present investigation was carried out to study the distribution of Staphylococcal Cassette Chromosome Mec (SCCmec) types and antibiotic resistance properties in methicillin-resistant Staphylococcus aureus isolated from Isfahan hospitals. Materials and Methods: A total of 250 clinical specimens ...
متن کاملStaphylococcus aureus CC395 harbours a novel composite staphylococcal cassette chromosome mec element
Background CoNS species are likely reservoirs of the staphylococcal cassette chromosome mec (SCC mec ) in Staphylococcus aureus . S . aureus CC395 is unique as it is capable of exchanging DNA with CoNS via bacteriophages, which are also known to mediate transfer of SCC mec . Objectives To analyse the structure and putative origin of the SCC mec element in S . aureus CC395. Methods The only ...
متن کاملStaphylococcal cassette chromosome mec-like element in Macrococcus caseolyticus.
Macrococcus is a bacterial genus that is closely related to Staphylococcus, which typically is isolated from animal skin and products. The genome analysis of multidrug-resistant Macrococcus caseolyticus strain JCSC5402, isolated from chicken, previously led to the identification of plasmid pMCCL2, which carries a transposon containing an unusual form of the Macrococcus mec gene complex (mecA(m)...
متن کاملTyping of staphylococcal cassette chromosome mec encoding methicillin resistance in Staphylococcus aureus isolates in Ahvaz, Iran
Methicillin-resistant Staphylococcus aureus (MRSA) is a major nosocomial pathogen. We sought to determine the frequency of the different types of SCCmec in MRSA isolates by performing a cross-sectional study. A total of 72 S. aureus isolates were collected from Imam Khomeini and Golestan hospitals and analysed for MRSA and SCCmec typing by multiplex PCR. The pattern of antibiotic resistance amo...
