Molecular characterization of glycoprotein genes and phylogenetic analysis of two swine paramyxoviruses isolated from United States

Abstract: Two swine paramyxoviruses (SPMV)-(81-19252 (Texas-81) and 92-7783 (ISU-92)-were isolated from encephalitic pigs in the United States in 1981 and 1992. Antigenic, morphologic, and biological characteristics of these two viruses were essentially similar to members of the family Paramyxoviridae. Antigenic analysis by indirect fluorescent antibody, immunoblot, and one-way cross-neutralization tests placed these viruses along with bovine parainfluenza 3 (BPIV3) viruses. Purified virions were 50-300 nm in size and m… Show more

“…The phylogenetic reconstructions based on the complete M protein amino acid sequences reveal two distinct genetic groupings formed by bPIV3-910N-like and bPIV3-SF-like viruses. In addition, deduced amino acid sequences of M proteins (this study) and the F and HN proteins (57) indicate that Texas81 and ISU92 belong to two subgenotypes of genotype A and that the Australian bPIV3 strain Q5592 belongs to a separate genotype, genotype B (Fig. 1B).…”

“…We have recently reported the molecular characterization of the envelope glycoprotein genes of these two swine viruses (57). In the putative antigenic sites of the F protein, there were several amino acid differences from hPIV3, including E101N, V/T367I (only in ISU92), S418Q, T492A, and T513V, but the amino acids were conserved in the swine viruses and bPIV3.…”
