摘要

Three outbreaks of Legionnaires' disease were reported in the Fredrikstad/Sarpsborg community, Norway, in 2005 and 2008 caused by the L pneumophila STI5 and ST462 strains determined by sequence based typing. In this retrospective study, we suggestthat the aeration ponds, a part of the biological treatment plant at Borregaard Ind. Ltd., are the main amplifiers and primary disseminators of the outbreak L. pneumophila strains. This result is supported by the finding that the ST15 and ST462 strains were not able to survive in air scrubber liquid media more thanlwodays of incubation atthe scrubber's operating conditions during the 2005 and 2008 outbreaks. In 2008, >10~(10) CFU/L of L. pneumophila ST462 were detected in the aeration ponds. ST15 and ST462 were also detected in the river Glomma in 2005 and 2008, respectively, downstream of the wastewater outlet from the treatment plant (10~5 CFU/L). These findings strongly suggestthatthe presence of L. pneumophila in the river is due to the release of wastewater from the industrial aeration ponds, demonstrating that the river Glomma may be an additional disseminator of L pneumophila during the outbreaks. This work emphasizes the need for preventive actions against the release of wastewater containing human pathogens to the environment

STI5和ST462菌株引起的。在这项回顾性研究中，我们建议，曝气池是Borregaard Ind。Ltd.生物处理厂的一部分，是暴发性嗜肺乳杆菌菌株的主要扩增子和主要传播剂。这一发现得到了以下发现的支持：在2005年和2008年爆发期间，ST15和ST462菌株在洗涤塔的操作条件下孵育超过两个星期后，无法在空气洗涤塔液体培养基中存活。 2008年，曝气池中检测到嗜肺乳杆菌ST462的> 10〜（10）CFU / L。 ST15和ST462分别于2005年和2008年在格洛马河中检测到，位于处理厂废水出口的下游（10〜5 CFU / L）。这些发现强烈表明，河中存在肺炎链球菌是由于工业曝气池释放了废水，这表明格洛玛河可能是暴发期间肺炎链球菌的另一种传播者。这项工作强调需要采取预防措施，以防止将含有人类病原体的废水释放到环境中
