Abstract excerpt
Porcine reproductive and respiratory syndrome virus (PRRSV) strains from 13 states in the United States, Guatemala and Canada were used to compare the envelope glycoprotein gene (ORF 5) nucleotide and deduced amino acid sequences. The gene was the same size, 603 nt, for all the 22 field strains. These strains had 89-94% amino acid identity compared to reference strain VR 2332. A putative signal sequence and...
