Prevalence and phylogenetic analysis of porcine deltacoronavirus in Sichuan province, China.

ABSTRACT: In order to understand the prevalence and genetic diversity of porcine deltacoronavirus (PDCoV) in diarrhoeal pigs in Sichuan province, 634 clinical samples were collected from individual pigs with diarrhoea in 13 regions of Sichuan province, China, from January 2017 and June 2019. The detection results showed that the infection rate of PDCoV was relatively low in diarrhoeal pigs, 13.25% (84/634), but the infection rate of PEDV (porcine epidemic diarrhea virus) was high, 32.18% (204/634). Coinfection with PEDV was common (55.95%, 47/84) in PDCoV-infected diarrhoeal pigs. Additionally, the chance of PDCoV infection was 2.77 times higher in suckling piglets than in sows, and about 3.30 times higher in spring and winter than in summer. PDCoV/PEDV coinfection was 75% less likely in sows than i
