| multiple infection of porcine torque teno virus in a single pig and characterization of the full-length genomic sequences of four u.s. prototype pttv strains: implication for genotyping of pttv. | porcine torque teno virus (pttv) was recently shown to partially contribute to the experimental induction of porcine dermatitis and nephropathy syndrome and postweaning multisystemic wasting syndrome in pigs in the united states. we report here the identification of four distinct full-length genomic sequences of pttv strains from a single pig in virginia. detailed analyses of the genomic organization, the degree of variability and the characteristics of conserved nucleotide and amino acid motifs ... | 2010 | 19913866 |
