Abstract
Partial atlE sequencing (atlE nucleotides 2782 to 3114 [atlE(2782-3114)]) was performed in 41 Staphylococcus epidermidis isolates from prosthetic joint infections (PJIs) and 44 isolates from skin as controls. The atlE(2782-3114) allele 1 (type strain sequence) was significantly more frequent in PJI strains (38/41 versus 29/44 in controls; P = 0.0023). Most PJI strains were positive for mecA, icaA/icaD, and IS256, and most belonged to the sequence type 27 subgroup, suggesting the involvement of few related clones.
摘要
对41株来自人工关节感染（PJI）的表皮葡萄球菌分离株和44株作为对照的皮肤分离株进行了atlE部分测序（atlE核苷酸2782至3114 [atlE(2782 - 3114)]）。atlE(2782 - 3114)等位基因1（模式菌株序列）在PJI菌株中显著更常见（PJI菌株中为38/41，对照中为29/44；P = 0.0023）。大多数PJI菌株mecA、icaA/icaD和IS256呈阳性，且大多数属于序列类型27亚组，提示少数相关克隆参与其中。
