Italy 19 September, 2007

Since the end of May, 2007, thirteen LPAI outbreaks caused by a type A AI virus of the H7 subtype have occurred in Italy. Eight outbreaks have been identified in back-yard flocks or in dealer farms supplying the rural and hobby poultry sectors. On 22 August 2007, an H7N3 LPAI virus was
isolated in a meat turkey holding located in the Municipality of Paderno Francia-Corta in the Province of Brescia, Lombardia Region. From 22 to 31 August 2007, another 3 LPAI infected meat turkey holdings were identified in the same Region.
Furthermore, on 14 August 2007, an LPAI virus of the H5N2 subtype was isolated in a free-range goose and duck breeder flock in Emilia-Romagna Region. The HA gene showed a higher level of homology (98.5%) with H5N2 LPAI viruses isolated from wild waterfowl in Germany in 2005.
