SCCmec Typing in Methicillin-Resistant Staphylococcus aureus Strains of Animal Origin
To the Editor: Van Loo et al. described the presence of staphylococcal cassette chromosome mec (SCCmec) type III in some methicillin-resistant Staphylococcus aureus sequence type (ST) 398 isolates related to pig farming (1). SCCmec types are based on the allotype of ccr genes and the mec gene complex. Class A mec has intact mecI/R regulator genes. Type III SCCmec has type 3 ccr genes and class ...
متن کاملSCCmec typing and detection of VISA-related genes in methicillin-resistant Staphylococcus aureus clinical strains from Kobe University Hospital, Japan.
A total of 50 clinical strains of methicillin-resistant Staphylococcus aureus (MRSA) were collected from Kobe University Hospital in 2003. Molecular typing of SCCmec was performed by multiplex polymerase chain reaction (PCR) and the presence of six genes (vraR, vraG, vraA, vraF, fruA, and fruB) associated with vancomycin (VCM) resistance was examined by simple PCR analysis. Out of 50 MRSA strai...
متن کاملsccmec typing of methicillin-resistant staphylococcus aureus: an eight year experience
conclusions as about 70% of methicillin-resistant isolates belonged to sccmec iii, the present study can conclude that, over an 8-year period, only one dominant and stable clone of mrsa strain was found in tabriz hospitals. this finding could be a result of incorrect medical orientations, inadequate infection controlling policies, and insufficient preventive approaches. objectives the current s...
متن کاملExpression of SCCmec cassette chromosome recombinases in methicillin-resistant Staphylococcus aureus and Staphylococcus epidermidis.
OBJECTIVES Methicillin resistance in staphylococci is mediated by the mecA gene, which is carried on the staphylococcal cassette chromosome mec (SCCmec). SCCmec is responsible for vertical and horizontal transfer of methicillin resistance. Horizontal transfer implies first SCCmec excision from the chromosome. Site-specific excision is catalysed by the Ccr recombinases, which are encoded by ccrA...
متن کاملDetection anD typing methoDs of methicillin-resistant StaphylococcuS aureuS strains
Staphylococcus aureus is one of the most important pathogens in hospital infections and its importance in the community is also prominent, especially since the 1990’s. Today methicillin-resistant Staphylococcus aureus (MRSA) is one of the most common causes of hospital infection, causing 40-70% of staphylococcal infections in intensive care units. Data on the prevalence of MRSA isolates differ ...
