Eight-day pregnant mice were found to be more resistant to the lethal effects of group B streptococci than those which were 17 days pregnant. From studies on the multiplication of the organisms in vivo it is suggested that the apparent enhancement of the infection in the 17-day pregnant animals is due to the lethal effects of the greater number of streptococci found in their tissues.
研究发现,怀孕8天的小鼠比怀孕17天的小鼠对B组链球菌的致死作用更具抵抗力。通过对该病原体在体内繁殖情况的研究表明,怀孕17天的动物体内感染明显加重,是由于其组织中发现的大量链球菌产生的致死作用所致。
