Parainfluenza virus, PIV, contains a group of four distinct serotypes of single-stranded RNA viruses belonging to the paramyxovirus family and two subtypes (4a and 4b). Parainfluenza viruse is a negative-sense, single-stranded RNA viruse that possess fusion and hemagglutinin-neuraminidase glycoprotein "spikes" on their surface. The virion varies in size (average diameter between 150 and 300 nm) and shape.

Allantoic fluid of 10 days old embryonated eggs, inoculated with parainfluenza-1 virus, strain Sendai. The Parainfluenza-1 Virus was purified by Ultracentrifugation with 20-60 % sucrose gradient.

Thimerosal and beta propiolactone treatment.
