The influence of different stages of pregnancy on group B streptococcal infection in mice.
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.
