In this brief communication we describe the occurrence of a KPC-producing Serratia marcescens isolate in a home-care patient from Recife, Brazil. The blaKPC, blaSPM, blaIMP, blaVIM, blaOXA, blaCTX-M, blaSHV, blaTEM and blaGES genes were investigated by Polymerase Chain Reaction (PCR) and DNA sequencing. The isolate was positive for blaKPC-2 and blaTEM-1 and was resistant to aztreonam, cefepime, cefotaxime, imipenem, meropenem, gentamicin, ciprofloxacin and cefazidime, and susceptible only to amikacin, tigecycline and gatifloxacin. This is the first report in Brazil of KPC-producing S. marcescens clinical isolate outside of a hospital environment. Caregivers should be alert for the presence of this isolate in the community setting.
在本简短通讯中,我们描述了从巴西累西腓的一名家庭护理患者中分离出一株产KPC的粘质沙雷氏菌。通过聚合酶链反应(PCR)和DNA测序对blaKPC、blaSPM、blaIMP、blaVIM、blaOXA、blaCTX - M、blaSHV、blaTEM和blaGES基因进行了研究。该分离株blaKPC - 2和blaTEM - 1呈阳性,对氨曲南、头孢吡肟、头孢噻肟、亚胺培南、美罗培南、庆大霉素、环丙沙星和头孢唑林耐药,仅对阿米卡星、替加环素和加替沙星敏感。这是巴西首次报道在医院环境外分离出产KPC的粘质沙雷氏菌临床菌株。护理人员应警惕社区环境中存在这种分离株。
