Table 2.
The presence of enterotoxin(-like) genes in CA-MRSA isolates with different STs.
| PVL/ACME Genes | ST (CC) | Total No. of Isolates (n = 100) | SE(-Like) Genes Identified *2 |
|---|---|---|---|
| PVL+/ACME+ | ST8 (CC8) | 9 *1 | sek, seq, selw, selx |
| PVL+/ACME- | ST30 (CC30) | 1 *1 | sem, sen, seo, seu, selw, selx |
| ST59 (CC59) | 1 *1 | seb, sek, seq, selw, selx | |
| PVL-/ACME+ | ST5/ST764 (CC5) | 15 *1 | seb (67%), sec (20%), seg, sei, sem, sen, seo, seu, sep (33%), selw, selx, sey |
| PVL-/ACME- | ST8 (CC8) (CA-MRSA/J *3) | 5 *1 | sec, sel, sep, selw, selx |
| ST8 (CC8) | 14 | selj (29%), ser (29%), selw (93%), selx (93%), sey (43%) | |

ST, sequence type; CC, clonal complex. *1 For these 31 isolates, genotypes and enterotoxin genes profile had been already reported in our previous study [33]. *2 None of isolate had sed, see, ses and set. When SE(-like) genes were not present in all the isolates of the same ST, their detection rate (%) are indicated in parentheses. *3 CA-MRSA/J represents ST8 MRSA carrying SCCmec IVl.
