H-1 and X14 parvovirus antibodies in women with abortions or still-births.

Antibodies against H-1 and X14 parvoviruses were found 13.71 and 9.14%, respectively, of 350 sera from women affected by repeated abortions or still-births. On the contrary, only 2.66 and 1.66% of 300 control sera were positive to the two viruses. The difference in the incidence of antibodies appears highly significant (p greater than 0.001). Therefore a possible role of the parvoviruses in inducing abortions or still-births in humans is suggested.
