Key result
Antibodies specific for St-Valérien-like virus were detected in 10.3% of 614 Italian swine serum samples, indicating that these infections are common among domestic pigs.
Cross-Sectional (n=614)
St-Valérien-like calicivirus infections are common among domestic pigs in Italy, with a seroprevalence of 10.3%.
Seroprevalence indicates endemic swine infection; leaves open zoonotic risk and need for prospective studies.
St-Valérien-like viruses are newly recognized porcine caliciviruses recently detected in North America and Europe. In this study, baculovirus-expressed virus-like particles of the St-Valérien strain 25A/ITA were generated and used for the development of an antibody-detection ELISA kit to assess the seroprevalence of these novel caliciviruses in swine. Antibodies specific for St-Valérien-like virus were detected in 63 (10.3 %) of 614 serum samples tested with titres ranging from 1 : 50 (28.6 %) to 1 : 800 (40.7 %). These results indicate that St-Valérien-like infections are common among domestic pigs, italy.

Martino et al. (2011) conducted a cross-sectional in St-Valérien-like calicivirus infection (n=614). St-Valérien-like calicivirus was evaluated on Seroprevalence of St-Valérien-like virus antibodies. Antibodies specific for St-Valérien-like virus were detected in 10.3% of 614 Italian swine serum samples, indicating that these infections are common among domestic pigs.
