Isolation, genomic characterization, and pathogenicity of a Chinese porcine deltacoronavirus strain CHN-HN-2014.

Project description:Porcine deltacoronavirus (PDCoV) is an emerging swine coronavirus that causes diarrhea in piglets. Since the first outbreak of PDCoV in the United States in 2014, this novel porcine coronavirus has been detected in South Korea, Canada, Mexico, Thailand, and China. In this study, a Chinese PDCoV strain, designated CHN-HN-2014, was isolated from piglets with severe diarrhea on a pig farm in Henan Province, China, and examined with a specific immunofluorescence assay and electron microscopy. Genomic analysis showed that CHN-HN-2014 shares 91.6%-99.4% nucleotide identity with other known PDCoV strains. The pathogenicity of CHN-HN-2014 was further investigated in 5-day-old and 21-day-old piglets. Both kinds of piglets developed clear clinical symptoms, including vomiting, anorexia, lethargy, and severe diarrhea, by 2days postinoculation (DPI), and diarrhea persisted for about 5-6 days. Viral shedding was detected in rectal swabs until 14 DPI in challenged 5-day-old pigs and until 18 DPI in challenged 21-day-old pigs. At necropsy at 4 DPI, macroscopic and microscopic lesions were observed and viral antigen was detected in the small intestines with immunohistochemical staining. These data demonstrate that Chinese PDCoV strain CHN-HN-2014 shares high nucleotide identity with previously reported PDCoV strains and is pathogenic in 5-day-old and 21-day-old piglets.

Genomic characterization and pathogenicity of porcine deltacoronavirus strain CHN-HG-2017 from China.

Project description:Porcine deltacoronavirus (PDCoV) was first detected in Hong Kong and has recently spread to many countries around the world. PDCoV causes acute diarrhea and vomiting in pigs, resulting in significant economic losses in the global pork industry. In this study, a Chinese PDCoV strain, designated CHN-HG-2017, was isolated from feces of a suckling piglet with severe watery diarrhea on a farm located in central China. Subsequently, the virus was identified by an indirect immunofluorescence assay and electron microscopy. A nucleotide sequence alignment showed that the whole genome of CHN-HG-2017 is 97.6%-99.1% identical to other PDCoV strains. Analysis of potential recombination sites showed that CHN-HG-2017 is a possible recombinant originating from the strains CH/SXD1/2015 and Vietnam/HaNoi6/2015. Furthermore, the pathogenicity of this recombinant PDCoV strain was investigated in 5-day-old piglets by oral inoculation. The challenged piglets developed typical symptoms, such as vomiting, anorexia, diarrhea and lethargy, from 1 to 7 days post-inoculation (DPI). Viral shedding was detected in rectal swabs until 14 DPI in the challenged piglets. Interestingly, high titers of virus-neutralizing antibodies in sera were detected at 21 DPI. Tissues of small intestines from CHN-HG-2017-infected piglets at 4 DPI displayed significant macroscopic and microscopic lesions with clear viral antigen expression. Our analysis of the full genome sequence of a recombinant PDCoV and its virulence in suckling piglets might provide new insights into the pathogenesis of PDCoV and facilitate further investigation of this newly emerged pathogen.

Complete Genome Characterization of the Porcine Deltacoronavirus HKD/JPN/2016, Isolated in Japan, 2016.

Project description:In 2016, an outbreak of diarrhea with high mortality in piglets occurred on a swine farm in Hokkaido prefecture, Japan. The causative porcine deltacoronavirus HDK/JPN/2016 was isolated from intestinal samples of the dead piglets on LLC-PK1 cells. The complete genome of HKD/JPN/2016 was sequenced and analyzed by next-generation sequencing technology.

Project description:Two porcine deltacoronavirus (PDCoV) strains, named DH1/2016 and DH2/2016, were isolated from feces of piglets which had severe watery diarrhea symptoms.

Prevalence, complete genome sequencing and phylogenetic analysis of porcine deltacoronavirus in South Korea, 2014-2016.

Project description:Porcine deltacoronavirus (PDCoV) is a newly emerged enterotropic swine coronavirus that causes enteritis and diarrhoea in piglets. Here, a nested reverse transcription (RT)-PCR approach for the detection of PDCoV was developed to identify and characterize aetiologic agent(s) associated with diarrhoeal diseases in piglets in South Korea. A PCR-based method was applied to investigate the presence of PDCoV in 683 diarrhoeic samples collected from 449 commercial pig farms in South Korea from January 2014 to December 2016. The molecular-based survey indicated a relatively high prevalence of PDCoV (19.03%) in South Korea. Among those, the monoinfection of PDCoV (9.66%) and co-infection of PDCoV (6.30%) with porcine epidemic diarrhoea (PEDV) were predominant in diarrhoeal samples. The full-length genomes or the complete spike genes of the most recent strains identified in 2016 (KNU16-07, KNU16-08 and KNU16-11) were sequenced and analysed to characterize PDCoV currently prevalent in South Korea. We found a single insertion-deletion signature and dozens of genetic changes in the spike (S) genes of the KNU16 isolates. Phylogenetic analysis based on the entire genome and spike protein sequences of these strains indicated that they are most closely related to other Korean isolates grouped with the US strains. However, Korean PDCoV strains formed different branches within the same cluster, implying continuous evolution in the field. Our data will advance the understanding of the molecular epidemiology and evolutionary characteristics of PDCoV circulating in South Korea.
