A strain of Amoeba proteus has lost its ability to survive at temperatures above 26 degrees C as a result of becoming dependent on endosymbiotic bacteria that are psychrophile-like. The observed temperature sensitivity develops in fewer than 200 host cell generations (18 months of culture) after the host cells are experimentally infected with the symbionts.
一种变形虫由于依赖类似于嗜冷菌的内共生细菌,已经失去了在 26°C 以上温度下生存的能力。在宿主细胞被实验性感染共生体后不到 200 代(18 个月的培养),就观察到了这种温度敏感性的发展。
