“…The clinical symptoms of PDCoV disease are very similar to those of porcine epidemic diarrhea, but PDCoV disease is milder [4]. Since April 2017, disease caused by PDCoV strains has been reported in North America (the United States, Canada, and Mexico) [5][6][7][8][9][10] and Asia, including South Korea, Mainland China, Thailand, Laos, and Vietnam [11][12][13][14][15][16][17].…”

“…Most of the viral strains (01, 02, 09, 12 and 13) had a high nucleotide similarity (0.985–0.990) with CHJXNI2/China/2015 (Song et al., ). On the other hand, 04, 06, 07, 08, 10, 11 shared 0.988–0.992 similarity with CHN/JS/2014 (Dong et al., ). Unlike the other strains from this work, 03 had the highest nucleotide homology (0.971) with HKU15‐44, a strain first identified from swine in Hong Kong.…”

“…RT‐PCR detection methods have provided data for the prevalence of PDCoV in China (Dong et al., ; Song et al., ; Zhai et al., ). A previous study (Zhai et al., ) reported that the current prevalence in Southern China was 1.54% (5/390), and three of the five detected strains were from Guangdong Province, revealing that the information regarding the molecular epidemiology of PDCoVs in Guangdong was still limited.…”

Porcine deltacoronavirus (PDCoV) is a newly discovered coronavirus that causes diarrhoea, vomiting and dehydration in sucking and nursing piglets. It was first reported in Hong Kong in 2012 and has since been discovered in the United States, Canada, South Korea, mainland China, Thailand and Laos. PDCoV has been experimentally proved to lead to diarrhoea in swine and it was detected positive in pigs in Guangdong, southern China. In our study, 252 faecal and intestinal samples from sucking piglets and sows with diarrhoea were surveyed for common enteric viruses. We found a prevalence of PDCoV (21.8%), porcine epidemic diarrhoea virus (65.5%), transmissible gastroenteritis virus (0%), rotavirus group A (25.0%) and porcine kobuvirus (68.7%). We isolated 13 PDCoV strains and discovered that PDCoV infections were often co-infections with kobuvirus rather than the commonly linked porcine epidemic diarrhoea virus. Phylogenetic analysis of S gene and N gene revealed that 11 of 13 PDCoV strains belonged to Chinese lineage. As for the left two strains, one single strain (CHN-GD16-05) belonged to American and Korean lineages while another strain (CHN-GD16-03) was similar to a Thai strain, but only in the S gene. This suggested a possible recombination event between the Thai and the newly described Chinese strain.

“…The American PDCoVthat was discovered in Ohio and Indiana, rapidly spread to other states in the USA and Canada, and caused significant economic losses in the swine industry . PDCoV has also been identified in Canada, Thailand, Korea and China (Dong et al, 2015;Homwong et al, 2016;Janetanakit et al, 2016;Lee et al, 2016;Song et al, 2015).Genome analysis has revealed that USAPDCoV isolates share a close relationship (99.7% sequence identity) with Hong Kong and South Korean PDCoV strains, and with CoVsisolated in Asian leopard cat and Journal "Veterinaria i kormlenie" èçìåíåíèé, êîòîðûå èãðàþò êëþ÷åâóþ ðîëü â óìåíüøåíèè âèðóëåíòíîñòè, ýòî ìîaeåò ïîñïîñîáñòâîâàòü ðàçðàáîòêå ýôôåêòèâíûõ âàêöèí.…”
