医院由于病人流量大,携带的病原微生物繁多,常常会引起健康人体感染这些疾病。目前,医院感染是现代医院管理中的一大难题,尤其是在儿科门诊,因为儿童的免疫力差,前往治疗的儿童往往会感染其它的疾病。

医院由于病人流量大,携带的病原微生物繁多,常常会引起健康人体感染这些疾病。目前,医院感染是现代医院管理中的一大难题,尤其是在儿科门诊,因为儿童的免疫力差,前往治疗的儿童往往会感染其它的疾病。对此,台湾长庚大学新兴病毒感染研究中心的Kuo-Chien Tsao等人开展了一项有意义的研究,他们评估了位于北部台湾儿童医院门诊部门空气中的腺病毒和肺炎支原体的分布状况,籍此来为医院病原颗粒分布与人类感染可能性研究做好铺垫。相关研究发表与3月21日的美国《公共科学图书馆·综合》(PLoS ONE)上。

研究过程中,为期一年的空气中病毒以及细菌密度评估一周测量两次,每次以每分钟气流量12公升的速率过滤取样,每次在儿科门诊连续测量8个小时,在儿科急诊连续测量24小时。使用适时聚合酶链反应来分析空气样品表明:来自儿科急诊大约18%的气体样品被发现含有腺病毒,而来自儿科门诊大约46%的空气样品含有肺炎支原体DNA产物。研究还发现,腺病毒DNA高检出率主要集中在7月和8月的儿科公共区域。在儿科急诊病房,空气中的肺炎支原体仅仅在7月被检测到,而在儿科门诊,峰值则持续发现于8月至来年1月。

结果表明,含有腺病毒以及肺炎支原体的空气微粒在儿科公共区域中是最普遍的,而这些腺病毒和细菌颗粒与人类感染之间可能性的关系应该被深入研究。(生物谷Deepblue编译)

Surveillance of Airborne Adenovirus and Mycoplasma pneumoniae in a Hospital Pediatric Department

This investigation evaluated the distributions of airborne adenovirus and Mycoplasma pneumoniae in public areas in the pediatric department of Children's Hospital in northern Taiwan. The airborne viral and bacterial concentrations were evaluated twice a week for a year using filter sampling with an airflow rate of 12 liters per minute for eight hours in the pediatric outpatient department and 24 hours in the pediatric emergency room.Real-time polymerase chain reaction assays were conducted for analysis. Approximately 18% of the air samples from the pediatric emergency room were found to contain adenovirus. Approximately forty-six percent of the air samples from the pediatric outpatient department contained Mycoplasma pneumoniae DNA products. High detection rates of airborne adenovirus DNA were obtained in July and August in the pediatric public areas.Airborne Mycoplasma pneumoniae was detected only in July in the pediatric emergency room and the peak levels were found from August to January in the pediatric outpatient department. Airborne particles that contained adenovirus and Mycoplasma pneumoniae were the most prevalent in the pediatric public areas. The potential relationship between these airborne viral/bacterial particles and human infection should be examined further..
