[Antibacterial and antimycotic activity of the amniotic fluid against selected germs (author's transl)].

60 samples of amniotic fluid from 60 patients were obtained between 14 and 42 weeks gestation by dates and tested for their antibacterial activity against staphlococcus aureus strains and brucella abortus and their antimycotic activity against Candida albicans. The antibacterial and antimycotic activity of the amniotic fluid was confirmed. This activity increases steadily from the 15th week and reaches its maximum around term between 36 and 42 weeks. The amniotic samples obtained at 20 weeks gestation showed a weak antibacterial activity especially against staphlococcus aureus of human origin. The above results are important because of the increasing frequency of early and late diagnostic amniocentesis in pregnancy.
