Extrarespiratory localizations of parainfluenza viruses.

Two hemagglutinating and hemadsorbant agents-serologically identified as parainfluenza viruses type 3-were isolated from the cerebrospinal fluid of a 10-month-old infant with meningoencephalitis and from the urethral secretion of a male patient with nonbacterial urethritis. Parainfluenza virus antigens types 1, 2, and 3 were detected by indirect immunofluorescence reactions in cells exfoliated in the vagina of women with genital neoplasia or common gynecopathies.
