The investigated material consisted of 74 wild birds representing 17 species, which due to various reasons (injuries, weakness, freezing) were delivered to the Division of Poultry Diseases during 2005-2007. Antibodies directed against NDV, REOV, EDS'76 virus, Salmonella Typhimurium (ST) and S. Enteritidis (SE) were examined in blood serum using ELISA kits. Antibodies against NDV were detected in six mute swans (75.0%), two mallards (50.0%), four white storks (20.0%), one sea eagle (50.0%), one buzzard (20.0%), and in a common scoter. Two of the investigated sea eagles (100%) were infected by EDS'76 virus. Antibodies against this virus were noticed also in seven mute swans (87.5%), seven white storks (35.0%), one mallard (25.0%), one herring gull (12.0%), and in a sparrow hawk. Thirty of the investigated birds belonging to seven species were infected by reovirus: seven mute swans (87.5%), six herring gulls (75.0%), two mallards (50.0%), 11 white storks (55.0%), two buzzards (40.0%), and one sea eagle (50.0%). High levels of ST antibodies were detected in 34 examined birds - seven herring gulls (87.0%), three buzzards (60.0%), 14 white storks (70.0%), five mute swans (62.5%), one sea eagle (50.0%), and one mallard (25.0%). Similar results were obtained when SE antibodies were detected.
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.
