We tested 214 Staphylococcus aureus isolates for the arcA locus of the arginine catabolic mobile element (ACME). All USA300 SCCmec IVa isolates, but no isolates containing other SCCmec subtypes, were arcA positive. arcA was also detected in selected methicillin-susceptible USA300 and methicillin-resistant USA100 isolates. DNA sequence analysis confirmed the integration of ACME in orfX.
我们检测了214株金黄色葡萄球菌分离株的精氨酸分解代谢移动元件(ACME)的arcA基因座。所有USA300 SCCmec IVa分离株均为arcA阳性,但含有其他SCCmec亚型的分离株均为阴性。在选定的甲氧西林敏感USA300和甲氧西林耐药USA100分离株中也检测到了arcA。DNA序列分析证实了ACME整合到orfX中。
