Abstract excerpt
The extent of genetic variation and evolution in a population of human parainfluenza virus type 1 was investigated. The hemagglutinin neuraminidase genes of 13 isolates collected over a 26-year period were sequenced and compared. All isolates except the 1957 type strain were from a single geographic location and demonstrated significant consistent genetic change from the type strain (47/7 [nucleotide/amino acid]...
