Detection and Phylogenetic Analysis of Porcine Deltacoronavirus in Korean Swine Farms, 2015	2016-03-10		.txt	text/plain	1826	110	62	In this study, faecal samples of pigs showing signs of diarrhoea (n = 681) collected from January 2013 to March 2015 were screened for the presence of porcine deltacoronavirus (PDCoV). The phylogenetic trees showed that Korean PCDoV isolates in 2014 (KNU14.04) and in 2015 (SL2, SL5) were grouped within US PDCoV cluster, but they located at different branches (highlights). For the genetic characterization, the maximum likelihood phylogenetic trees reconstructed from the S and N genes (Fig. 1a, b) showed a clear separation between Chinese and US strains of PDCoV and is similar to the previous studies (Marthaler et al., 2014; Wang et al., 2016) . Based on the S gene, the inferred ancestral amino acid changes along the nodes of the phylogeny (Fig. 2a) showed that the branches leading to Korean PDCoV isolates in 2014 and in 2015 shared 1 back substitution (node #40: Q106L, node #37: L106Q) and four unique substitutions (node #39: S697A, node #38: V550A, I669L and node #37: I1014V).	./cache/cord-260212-m80dkzm4.txt	./txt/cord-260212-m80dkzm4.txt
