Detection of Integrons and Staphylococcal Cassette Chromosome mec Types in Clinical Methicillin-resistant Coagulase Negative Staphylococci Strains
OBJECTIVES Integrons are thought to play an important role in the spread of antibiotic resistance. This study investigates class 1 and 2 integron-positive methicillin-resistant coagulase-negative staphylococci strains isolated in Iran and characterizes their patterns of antimicrobial resistance. METHODS Hundred clinical isolates of coagulase-negative staphylococci were characterized for integ...
متن کاملLocal variants of Staphylococcal cassette chromosome mec in sporadic methicillin-resistant Staphylococcus aureus and methicillin-resistant coagulase-negative Staphylococci: evidence of horizontal gene transfer?
The mecA gene in Staphylococcus aureus is located on the genetic element staphylococcal cassette chromosome (SCC). Different SCCmecs have been classified according to their putative recombinase genes (ccrA and ccrB) and overall genetic composition. Clinical isolates of coagulase-negative staphylococci (CoNS; n = 39) and S. aureus (n = 20) from Norway, India, Italy, Finland, the United States, a...
متن کاملmethicillin resistant staphylococcus aureus (mrsa) strains and the staphy lococcal cassette chromosome mec types in iran
background: staphylococcus aureus can cause infections with a wide spectrum of illnesses ranging from benign skin infections to bloodstream infection leading to mortality. antimicrobial resistance especially methicillin resistance in s. aureus (mrsa strains) is currently problematic. the emergence of mrsa infections has developed in both the healthcare and the community settings. the aim of th...
متن کاملStaphylococcal Cassette Chromosome mec Types Among Methicillin-Resistant Staphylococcus aureus in Northern Iran
BACKGROUND Methicillin-resistant Staphylococcus aureus (MRSA) is a common cause of nosocomial and community-acquired infections around the world. Staphylococcal cassette chromosome mec (SCCmec) typing methods are often used to study MRSA molecular epidemiology. OBJECTIVES The current study was designed to explore the distribution profiles of different SCCmec types among methicillin-resistant ...
متن کاملSubtyping of Chilean Methicillin-Resistant Staphylococcus aureus strains carrying the staphylococcal cassette chromosome mec type I
The cassette chromosome mec (SCCmec) present in methicillin-resistant Staphylococcus aureus (MRSA) has two essential components, the ccr gene complex and the mec gene complex. Additionally, SCCmec has non-essential components called J regions which are used for MRSA subtyping. This study was performed to determine subtypes MRSA strains carrying SCCmec type I based on polymorphism of regions loc...
