Antimicrobial susceptibility and molecular characteristics of 857 methicillin-resistant Staphylococcus aureus isolates from 16 medical centers in Japan (2008–2009): nationwide survey of community-acquired and nosocomial MRSA

Current concepts on the virulence mechanisms of meticillin-resistant Staphylococcus aureus

“…USA300) were the most common among the blood isolates. This finding differs from a nationwide survey study of MRSA strains from Japan conducted between 2008 and 2009 (Yanagihara et al, 2012). There the most common SCCmec types were type II (73.6 %), type IV (20 %) and type 1 (6 %).…”

Risk factors for anti-MRSA drug resistance

“…Especially in a study from Japan, SCCmec type II is the most relevant and is often seen in hospitalised patients, and 100% of MRSA strains with this type showed susceptibility to LZD [20], suggesting that the case in the current study may be considered rare but needs caution as a new finding.…”

Molecular epidemiologic study of community-associated methicillin-resistant Staphylococcus aureus with Panton-Valentine leukocidin gene among family members in Japan

“…USA300 is a major CA-MRSA strain with PVL, however both USA300 and strains with PVL are low in prevalence in Japan. Previously, PVL-positive MRSA was reported to be ST30, as we found in family A [7,8]. The B and C families had ST8 with PVL gene.…”
