Genetic Diversity among Community Methicillin-Resistant Staphylococcus aureus Strains Causing Outpatient Infections in Australia

Abstract

Increasing reports of the appearance of novel nonmultiresistant methicillin-resistant

Differing epidemiology of two major healthcare-associated meticillin-resistant Staphylococcus aureus clones

“…MRSA isolates resistant to at least three non-beta-lactam antibiotics in different antibiotic classes were defined as multi-resistant MRSA (lincosamides and macrolides were considered a single antibiotic class); all other isolates were non-multi-resistant MRSA. 14 Isolates were typed using a multi-locus sequence typing (MLST)-based high-resolution melting scheme that provides inferred MLST clonal complexes (CC), as described previously. 15 Isolates typed as CC22 and CC239 have previously been determined to represent ST22 and ST239 accurately in this context.…”

Detection and simultaneous confirmation of Methicillin-Resistant Staphylococcus aureus by an automated Real-Time PCR method with strain differentiation by analysis of DNA melting curve characteristics

“…Additionally, as MRSA strains become progressively common in a variety of settings, the use of restrictive terms like HA-MRSA and CA-MRSA will become less meaningful as spread between all populations occur. The potential to recover an increasing array of SCCmec types, especially from community-occurring MRSA strains, clearly exists [20].…”

“…Bakteri penyebab infeksi nosokomial ini bersifat multiresisten, yaitu kebal terhadap semua jenis antimikrob golongan betalaktam dan terhadap lebih dari 2 macam antimikrob nonbetalaktam. 1 Spektrum infeksi yang ditimbulkan oleh MRSA bersifat sangat luas, yaitu mulai dari infeksi kulit yang ringan hingga infeksi berat seperti endokarditis dan sepsis. 2 Sejauh ini dilaporkan hanya vankomisin yang masih peka terhadap MRSA.…”
