摘要
目的了解集中空调通风系统送风中溶血性链球菌的污染和菌种的分布特征。方法于2008—2010年夏季期间4次对福建省属直管的9家大型宾馆集中空调采集的送风口空气样品进行溶血性链球菌检测,依据卫生部《公共场所集中空调通风系统卫生规范》的采样和检测方法,确定为溶血性链球菌的菌株,经纯培养后进一步采用VITEK全自动微生物鉴定仪鉴定。结果共分离到溶血性链球菌24株,β溶血性链球菌17株,包括4个种(无乳链球菌、停乳链球菌、马链球菌、酿脓链球菌);α溶血性链球菌7株,也包括4个种(肺炎链球菌、缓症链球菌、口腔链球菌、乳房链球菌)。菌株数从2008年8月首次监测时的15株降至2009年的5株、2010年的4株。结论福建省属直管的9家大型宾馆集中空调通风系统存在不同程度的溶血性链球菌污染,且经分离鉴定的菌株均是比较典型的致病代表株,经加强对公共场所集中空调的定期清洗和消毒等监管后,其污染程度有下降的趋势。
Objective To understand the contamination and distribution status of hemolytic Streptococcus in the central air conditioning systems in public places. Methods Four investigations were carried out in 2008-2010,according to ＂Hygienic Criterion for Central Air Conditioning Ventilation System in Public Places＇, identification of the hemolytic Streptococcus isolates was finished by VITEK auto microbiology system. Results Twenty-four isolates of hemolytic Streptococcus were identified, including 17 β-hemolytic Streptococcus,there were 11 of Streptococcus agalactiae, four of Streptococcus dysgalactiae,one of Streptococcus equi,one of Streptococcus pyogenes ;sevenα-hemolytic Streptococcus ,there were four of Streptococcus mitist, one of Streptococcus pneurnoniae, one of Streptococcus uberis, one of Streptococcus oralis. Conclusion The central air conditioning systems were contaminated with hemolytic Streptococcus, cleaning and disinfection of the systems will reduce the pollution.
