The structure of MES_PM1 and its segregants in ST59 CA-MRSA strains.

<p>Structures of MES_PM1, MES_PM9, MES_PM8, and MES_PM18 (corresponding to IS<i>1216V</i>) are shown in A to D. Drug resistance (r): Ery/Cli, erythromycin/clindamycin; Kan, kanamycin; Stm, streptomycin; Chl, chloramphenicol. The IS<i>1216V</i> region with the transposase gene (<i>tnp</i>) is shaded in blue. The <i>att</i> site is indicated by a vertical red line. Arrows below the MES structures indicate PCR primers, which are listed in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0046987#s4" target="_blank">Materials and Methods</a>.
