One PVL-negative isolate carried SCCmec IV as well as ccrA-1, ccrB-1 and the fusidic acid resistance marker Q6GD50 (fusC, GenBank BX571857.1:SAS0043). Thus it can be regarded as identical to the West Australian https://www.selleckchem.com/products/AZD1152-HQPA.html (WA) strain WA MRSA-45 and some of the isolates originally described as WA MRSA-1 [20, 23]. The other isolate was identified as PVL-positive ST772-V, also known as Bengal Bay Clone or WA MRSA-60. This is a distinct clone which differs from other CC1 strains in several features such as in the agr allele (II rather than III), capsule type (5 rather than 8), carriage of the enterotoxin-like gene
ORF CM14 (GenBank Farnesyltransferase U10927.2) and the absence of the enterotoxin H gene seh. Clonal complex 5 Both, PVL-negative as well as PVL-positive CC5-IV (Paediatric Clone or USA800) as well as one PVL-negative CC5-V isolate were found. Three isolates belonged to a strain previously known only from Malta . It is characterised by the presence of the fusidic acid resistance marker Q6GD50 (fusC) and additional recombinase genes beside a SCCmec IV element . One out of these isolates harboured, beside egc, also tst1, sec and sel (encoding toxic shock syndrome toxin, enterotoxins C and L). Clonal complex 6 Three isolates belonged to CC6-IV, which is identical to the Australian strains WA MRSA-51 and −66. They lacked PVL, but carried sea. Clonal complex 8/sequence type 239 All 22 CC8 isolates belonged to ST239-III, which is a divergent strain that emerged from an incorporation of a large fragment of CC30 DNA [24, 25]. All these isolates harboured the beta-lactamase-operon and tet(M) (tetracycline resistance) as well as, variably, further resistance genes as shown in Table 2. All isolates carried enterotoxin genes sek and seq. Patients carrying this strain were older than average (mean, 43 years; median, 39 years).
