A proactive environmental monitoring program was conducted to determine the risk and prevent nosocomial waterborne infections of spp. in infants. Sink taps in a neonatal intensive care unit (NICU) and two obstetric clinics were monitored for spp. A total of 59 water samples were collected during a 3-year period and 20 of them were found colonized with . Standard culture, molecular, and latex agglutination methods were used for the detection and identification of bacteria. Hospital personnel also proceeded with remedial actions (hyperchlorination and thermal shock treatment) in the event of colonization. The minimal inhibitory concentration (MIC) values of erythromycin, ciprofloxacin was determined for isolates using the e-test method. Our data indicate that the majority of neonatal sink-taps were colonized at least once during the study with spp. Among 20 isolates, 5 were considered as low-level resistant, 3 in erythromycin and 2 in ciprofloxacin, while no resistant strains were detected. Environmental surveillance in neonatal and obstetric units is suggested to prevent waterborne infections, and thus to reduce the risk of neonatal nosocomial infections.
开展了一项前瞻性环境监测计划，以确定风险并预防婴儿感染 spp. 的医院内水源性感染。对新生儿重症监护病房（NICU）和两家产科诊所的水槽水龙头进行了 spp. 的监测。在3年期间共采集了59份水样，其中20份被发现有 定植。采用标准培养、分子和乳胶凝集方法检测和鉴定 细菌。如果出现定植情况，医院工作人员还采取了补救措施（高氯消毒和热冲击处理）。使用e-test方法测定了 分离株对红霉素、环丙沙星的最低抑菌浓度（MIC）值。我们的数据表明，在研究期间，大多数新生儿水槽水龙头至少有一次被 spp. 定植。在20株分离株中，5株被认为是低水平耐药，3株对红霉素耐药，2株对环丙沙星耐药，未检测到耐药菌株。建议对新生儿和产科病房进行环境监测，以预防水源性感染，从而降低新生儿医院感染的风险。
