Summary.

 To investigate vertical transmission of TT virus, TTV-DNA was looked for in serum samples taken from 22 mothers and their 22 infants at birth and during nine months of follow-up. Sixteen mothers at delivery and six infants within nine months of age had TTV-DNA detected by the amplification of the non coding (NC) region. Two of these newborns had positive viremia at birth. Sequence analysis of the NC region of five mother-infant pairs revealed that the TTV strains detected at three and six months of age in two of the infants were closely related to that of their mothers, whereas two that became TTV-DNA positive at three moths had a different nucleotide sequence from that of their mothers. One of the two infants with detectable viremia at birth also had a different nucleotide sequence from her mother. These findings suggest that both in utero and perinatal transmission of TT virus may occur, and that the strain detected in the infants was not invariably dominant in the mothers at delivery.
