Abstract
The mathematical model describing the dynamics of the growth of L. pneumophila in aqueous environment in the presence of protozoa has been worked out. The model has demonstrated considerable heterogeneity of the initial population of virulent L. pneumophila strains. The number of bacteria capable of multiplication in Infusoria is no more than 0.1% of the initial population. The time of the generation of the infective agent inside Tetrahymena pyriformis is 2.8 hours.
摘要
已建立了描述嗜肺军团菌在原生动物存在的水环境中生长动力学的数学模型。该模型显示出有毒嗜肺军团菌菌株初始群体存在相当大的异质性。能够在纤毛虫中繁殖的细菌数量不超过初始群体的0.1%。在梨形四膜虫体内产生感染因子的时间为2.8小时。
