Abstract
Abstract: Thirty-nine influenza virus strains belonging to eight serologically distinct neuraminidase subtypes (N1 to N8) were examined in order to study the genetic variation which occurs within a subtype of influenza neuraminidase. RNA segment 6, which codes for neuraminidase, was sequenced from the 3′ end using the dideoxy method. The sequences obtained for the different subtypes reveal that there are several kinds of variation: (a) point mutations in the RNA which sometimes change the amino acid sequence, (b) short regions of many nucleotide and amino acid changes, (c) small insertions and/or deletions (usually three nucleotides or one amino acid at a time), and (d) large deletions (from 33 to 48 nucleotides in length).
