Abstract

Nosocomial surfaces are potential pathogen reservoirs. Our aim was to describe the microbial diversity and analyze microbial patterns of healthcare-associated pathogens in two step-down-care-units at a tertiary care hospital. We monitored infected patients over 45 days to describe microbial diversity and colonization patterns. A total of 2762 isolates were recovered from the sampled sites, coagulase-negative staphylococci represented 44.64% (1233/2762) of the isolates. The most frequently recovered ESKAPE species (, , , , , and ) were (7.53%; 208/2762 isolates) and / (5.18%; 143/2762). We recovered a high diversity of species, including potential pathogens. was detected more frequently on diverse surfaces and persisted in patients' nostrils during the hospital stay.

摘要

医院环境表面是潜在的病原体储存库。我们的目的是描述一家三级护理医院两个过渡护理单元中医疗保健相关病原体的微生物多样性并分析其微生物模式。我们对感染患者进行了45天的监测，以描述微生物多样性和定植模式。从采样部位共分离出2762株菌株，凝固酶阴性葡萄球菌占分离菌株的44.64%（1233/2762）。最常分离出的ESKAPE菌属（粪肠球菌、屎肠球菌、金黄色葡萄球菌、肺炎克雷伯菌、鲍曼不动杆菌和铜绿假单胞菌）是屎肠球菌（7.53%；208/2762株分离菌）和肺炎克雷伯菌/鲍曼不动杆菌（5.18%；143/2762）。我们分离出了高度多样的菌种，包括潜在病原体。在不同表面上更频繁地检测到[具体菌种未明确写出]，并且在患者住院期间在其鼻孔中持续存在。
