In this paper, 110 cases of pregnant women with cervical swabs were collected, of which 60 cases were paired with their infant oropharyngeal swabs for blood plate and hypertonic L-type culture. The positive rate of cervical bacterial L-type was 27.3%, of which 26 were Staphylococcus aureus, and the oral L-positive rate was 30 in neonates. O (17/18 for Staphylococcus aureus), indicating that the baby’s bacteria mainly from the mother’s birth canal, in addition, the cervix isolated 118 strains of bacteria, Gram-positive cocci 33.1%, Gram-negative rod 57.6 %, Mold 4. O%. 24 bacterial strains were isolated from oral cavity, of which 12 were Gram-positive cocci, 9 were Gram-negative bacilli and 1 was mold.
