Key result
New St-Valerien-like porcine caliciviruses show ~24% prevalence in North Carolina finisher pigs.
Why the study?
The prevalence and characterization of new St-Valerien-like porcine caliciviruses in finisher pigs in North Carolina were not well described.
What is the prevalence and genomic characteristics of St-Valerien-like porcine caliciviruses in finisher pigs in North Carolina?
What is the prevalence and genomic characteristics of St-Valerien-like porcine caliciviruses in finisher pigs in North Carolina?
A new St-Valerien-like porcine calicivirus is highly prevalent among finisher pigs in North Carolina, highlighting the need for further investigation into its disease potential.
Warrants enhanced swine surveillance; leaves open questions of pathogenicity and zoonotic potential.
Real-time reverse transcription PCR revealed that new St-Valerien-ike porcine caliciviruses are prevalent (2.6%-80%; 23.8% overall) in finisher pigs in North Carolina. One strain, NC-WGP93C, shares 89.3%-89.7% genomic nucleotide identity with Canadian strains. Whether these viruses cause disease in pigs or humans or are of food safety concern requires further investigation.
