Abstract:
... Blastocystis sp. is a common pathogen that infects the intestines of humans and animals, causing a threat to public health. However, little information on the prevalence and subtypes of Blastocystis sp. in diarrheic pigs in China is available. Herein, 1254 fecal samples were collected from diarrheic pigs in 37 intensive pig farms in Hunan, Jiangxi, and Fujian provinces in southern China, and the p ...

Like other coronaviruses, PEDV N protein is a nucleocapsid protein and abundantly presents at all stages of infection. Previously, we reported that the N protein of trypsin-independent PEDV 8aa is cleaved during virus replication. In thi ...
