[A case of perinatal transmission of human immunodeficiency virus--diagnosis of HIV infection by culture and PCR].

: A child born from a mother with HIV infection was reported. We have followed the patient from 3 month old of age. Her HIV antibody disappeared at 7 month by EIA, and at 10 month by WR. But we confirmed her HIV infection by PCR and HIV culture, repeatedly at those times, PCR and HIV culture are thought to be necessary for sero-negative infants born from mothers positive for HIV antibody.
