ABSTRACTSixcfr-harboring methicillin-resistantStaphylococcus aureus(MRSA) isolates, which belonged to the same clone of sequence type 5 (ST5)-staphylococcal cassette chromosomemecelement II (SCCmecII)-spat311, were investigated in this study. Complete sequencing of acfr-carrying plasmid, pLRSA417, revealed an 8,487-bp fragment containing a Tn4001-like transposon,cfr,orf1, and ISEnfa4. This segment, first identified in an animal plasmid, pSS-01, was observed in several plasmids from clinical coagulase-negative staphylococci in China, suggesting that thecfrgene, which might originate from livestock, was located in the same mobile element and disseminated among different clinical staphylococcal species.

ABSTRACT Staphylococcus aureus JH4899, a community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) isolate collected from a patient with systematically disseminated infection, is classified as sequence type 8 and carries the staphylococcal cassette chromosome mec type IVl (SCCmecIVl). It produces TSST-1, SEC, a newly discovered enterotoxin (SE1), and epidermal cell differentiation inhibitor A (EDIN-A). Here, we present the complete genome sequence of the chromosome and a plasmid harboring the se1 and ednA genes.

An advanced methicillin-resistantStaphylococcus aureus(MRSA) detection PCR approach targeting SCCmec-orfXalong withmecAandmecCwas evaluated forS. aureusand coagulase-negative staphylococci. The possession ofmecAand/ormecCwas correctly confirmed in all cases. All methicillin-susceptibleS. aureusstrains (n= 98; including staphylococcal cassette chromosomemecelement [SCCmec] remnants) and 98.1% of the MRSA strains (n= 160, including 10mecC-positive MRSA) were accurately categorized.

ABSTRACTTwenty-two of 1,103 methicillin-resistantStaphylococcus aureus(MRSA) isolates containing the type II staphylococcal cassette chromosomemecelement (SCCmec) (collected in Hokkaido, Japan, from 2008 to 2011) harbored the arginine catabolic mobile element (ACME). Five genetic variations were identified in the ACME-staphylococcal cassette chromosomemeccomposite islands, 66 to 79 kb in size. The percentage of ACME carriage temporally increased from 0.85% to 4.5% in parallel with the emergence of shorter variants (66 to 72 kb). Shorter variants may have a selective advantage and accelerate the dissemination of ACME in Japanese MRSA.

ABSTRACTApproximately 39% of methicillin-resistantStaphylococcus aureus(MRSA) sequence type 239 (ST239)-like bloodstream isolates from Liverpool Hospital (obtained between 1997 and 2008) carry an arginine catabolic mobile element (ACME). Whole-genome sequencing revealed that an ACME II variant is located betweenorfXand SCCmecIII, and based on pulsed-field gel electrophoresis patterns and temporal relationships of all ST239-like isolates (n= 360), ACME carriage may have contributed to subpulsotype strain replacement.

ABSTRACTThe structures of staphylococcal cassette chromosomemec(SCCmec) elements carried by 31 clonal complex 398 (CC398) methicillin-resistantStaphylococcus aureus(MRSA) strains isolated from the participants at a conference were analyzed. The SCCmecs were classified into novel types, namely, IX, X, V(5C2&5) subtype c, and IVa. Type V(5C2&5) subtype c, IX, and X SCCmecs carried genes conferring resistance to metals. The structures of SCCmecs from CC398 strains were distinct from those normally found in humans, adding to the evidence that humans are not the original host for CC398.

ABSTRACT Staphylococcus aureus is a commensal bacterium of humans that can cause a spectrum of diseases. An isolate’s capacity to cause disease is partially attributed to the acquisition of novel mobile genetic elements. This report provides the draft genome sequence of one methicillin-susceptible and seven methicillin-resistant clinical human S. aureus isolates.
