Figure 1 Scheme of experimental vertical transmission.

Figure 2 The mother and her litters were housed in one cage per family. For 12 h before their sacrifice, they were housed in grated cage and deprived diet.

Figure 3 Amplification of Helicobacter DNAs. All fetuses showed no transmission of H pylori at 2 wk after pregnancy. P: Positive control; N: Negative control; Mo: Mother; F: Fetuses.

Figure 4 Amplification of specific nucleic acids for H pylori. All litters showed no transmission of H pylori at parturition day. P: Positive control; N: Negative control; Mo: Mother; L: Litters.

Figure 5 At 3 wk postpartum, some of litters delivered from infected mothers revealed positive reaction. P: Positive control; N: Negative control; Mo: Mother; L: Litters.
