Feline Calicivirus (FCV) has been recognised as major oral and respiratory pathogen of cats. The high correlation among the field viruses and FCV-F9 serotype has represented the immunological bases for the employ of FCV-F9 serotype as a vaccine for calicivirosis in cats. The aim of this paper was to evaluate, by in vitro neutralization assays, the antigenic correlation among the vaccine F9 and FCV field strains isolated in Sicily (Italy) from cats showing clinical forms referable to calicivirus infection. The results confirm the low correlation between FCV-F9 strain and calicivirus strains spread in the feline population.

Aujeszky's disease (AD), Porcine reproductive and respiratory syndrome (PRRS) and Swine influenza (SI) are among the principal agents of respiratory diseases of pigs. The aim of the study was to determine the prevalence of antibodies to SHV-1, PRRSV and SIV in pigs reared in Sicily. An Enzyme Linked Immunosorbent Assay for the glicoprotein gE of Pseudorabies virus, for PRRSV and for SIV was performed. Antibodies against gE of SHV-1 were detected in 171 serum samples (14.6%), whereas PRRSV antibodies occurred at a higher frequency than SHV-1 with 289 (31.1%) samples being positive. The seroprevalence of SIV was found to be 33.3%. This study demonstrated the circulation of ADV, PRRSV and SIV viruses in Sicilian swine population. This is the first report on this topics in Sicily.
