| molecular characterization and phylogenetic analysis of porcine epidemic diarrhea virus (pedv) samples from field cases in fujian, china. | the outbreak of porcine epidemic diarrhea virus (pedv) has been a big problem of swine industry in china in recent years. in this study, we investigated molecular diversity, phylogenetic relationships, and protein characterization of fujian field samples with other pedv reference strains. sequence analysis of the s1 and sm genes showed that each sample had unique characteristics, and the sample p55 may be differentiated from the others by the unique deletions and insertions of sm gene. phylogene ... | 2012 | 22843324 |
