^a Nine mice at 6.5 gestational days were orally inoculated with ca. 2 x 10⁸ cfu of strain F6214-1. Four mice were later found not to be pregnant. Results from the remaining 5 mice are tabulated.

^bCfu are tabulated per organ (limit of detection 50 cfu per organ).

^cSum of scores for 5 embryos obtained from each mouse as determined in a blinded study described in the text.
