研究了嗜肺军团菌与自由生活的多食棘阿米巴变形虫之间的关系。通过动力学生长实验、光镜和电镜观察证实了嗜肺乳杆菌在阿米巴滋养体内的细胞内生长。被感染的滋养体产生的囊肿被发现可以保护军团菌免受至少50毫克/升的游离氯的侵害。嗜肺乳杆菌在多食单胞菌的囊内存活的能力被认为是该菌逃避消毒并扩散到新环境的可能机制。
The association between Legionella pneumophila and the free-living amoeba Acanthamoeba polyphaga was studied. Intracellular growth of L. pneumophila within amoebic trophozoite was confirmed by kinetic growth experiments, light and electron microscopy. Cysts produced from infected trophozoites were found to protect the legionella from at least 50 mg/l free chlorine. The ability of L. pneumophila to survive within the cysts of A. polyphaga is suggested as a possible mechanism by which the organism evades disinfection and spreads to colonize new environments.
