Enteric caliciviruses in the genera Norovirus and Sapovirus are important pathogens that cause severe acute gastroenteritis in both humans and animals. Cyclooxygenases (COXs) and their final product, prostaglandin E2 (PGE2), are known to play important roles in the modulation of both the host response to infection and the replicative cycles of several(More)
To determine the occurrence and genetic diversity of Sapelovirus A (SV-A) in diarrhea and non-diarrhea feces of Korean pigs, 110 specimens from different age groups of pigs in the same farm were analyzed by RT-nested PCR. SV-As were detected in 60% of both diarrhea and non-diarrhea specimens regardless of age groups with primer pairs for 2C region, in which(More)
This study analyzed eleven genomic segments of three Korean porcine G8P[7] group A rotavirus (RVA) strains. Phylogenetically, these strains contained two bovine-like and nine porcine-like genomic segments. Eight genes (VP1, VP2, VP6 and NSP1-NSP5) of strains 156-1 and 42-1 and seven genes (VP1, VP2, VP6 and NSP2-NSP5) of strain C-1 clustered closely with(More)
Sapelovirus A (SV-A), formerly known as porcine sapelovirus as a member of a new genus Sapelovirus, is known to cause enteritis, pneumonia, polioencephalomyelitis and reproductive disorders in pigs. We have recently identified α2,3-linked sialic acid on GD1a ganglioside as a functional SV-A receptor rich in the cells of pigs and chickens. However, the role(More)
