This study characterized 30 MRSA isolates from intensive care unit (ICU) environment and equipment surfaces and healthy children. The SCCmec types I, IVa and V were detected in HA-MRSA isolates while CA-MRSA showed the SCCmec type IVa and V. Most isolates were classified as agr group II. All isolates presented the sei gene, and only HA-MRSA were positive for etb e tst genes. Three genotypes were related to Pediatric (ST5/SCCmecIV) and Berlin (ST45/SCCmecIV) clones. The present study showed molecular similarity between CA- and HA-MRSA isolates in hospital and community settings in a Brazilian region.
本研究对来自重症监护病房（ICU）环境和设备表面以及健康儿童的 30 株 MRSA 分离株进行了特征描述。HA-MRSA 分离株中检测到 SCCmec 类型 I、IVa 和 V，而 CA-MRSA 则显示 SCCmec 类型 IVa 和 V。大多数分离株被归类为 agr 组 II。所有分离株均携带 sei 基因，只有 HA-MRSA 携带 etb 和 tst 基因。三种基因型与儿科（ST5/SCCmecIV）和柏林（ST45/SCCmecIV）克隆有关。本研究显示了巴西某地区医院和社区环境中 CA-MRSA 和 HA-MRSA 分离株之间的分子相似性。
