Abstract

A suspended cell culture procedure was described for the cultivation of guinea pig macrophages infected with Salmonella typhimurium. The fate of the intracellular bacteria was assessed by quantitative recovery of viable bacteria with 0.5% solution of sodium desoxycholate. Two strains of S. typhimurium with different degrees of virulence for mice were compared. There was an initial destruction of intracellular bacteria of both strains; however, the extent of this destruction differed. Approximately 1% of the avirulent bacteria initially phagocytized survived at the end of 4 hr, whereas approximately 8% of the virulent bacteria survived at the end of 3 hr. After this initial killing, the intracellular bacteria began to multiply at a logarithmic rate between 3 and 21 hr after phagocytosis, and then a stationary phase was attained. The rate of this multiplication was comparable for both strains.

摘要

描述了一种悬浮细胞培养程序,用于培养感染鼠伤寒沙门氏菌的豚鼠巨噬细胞。通过用0.5%脱氧胆酸钠溶液定量回收活菌来评估细胞内细菌的命运。比较了两株对小鼠毒力不同的鼠伤寒沙门氏菌。两株细菌的细胞内细菌最初都有破坏;然而,这种破坏的程度不同。最初吞噬的无毒力细菌在4小时结束时约有1%存活,而有毒力细菌在3小时结束时约有8%存活。在这种初始杀伤之后,细胞内细菌在吞噬后3至21小时之间开始以对数速率繁殖,然后达到稳定期。两株细菌的繁殖速率相当。
