From 24 May to 30 October 2007, sixteen low pathogenicity avian influenza (LPAI) outbreaks caused by a type A AI virus of the H7N3 subtype occurred in Northern Italy. Ten outbreaks were identified in rural or hobby flocks containing different poultry and ornamental bird species. Most of the affected premises were detected during the implementation of the national AI monitoring plan and at the time of sampling none of the birds showed any symptoms. Epidemiological investigations revealed commercial links (movement of live birds) between 8 of these farms. From 22 August to 2 October 2007 six infected meat turkey farms were identified in the Lombardy Region. These birds showed mild respiratory disease associated with anorexia and a slightly increased mortality rate.

Abstract
From 24 May to 30 October 2007, sixteen low pathogenicity avian influenza (LPAI) outbreaks caused by a type A AI virus of the H7N3 subtype occurred in Northern Italy. Ten outbreaks were identified in rural or hobby flocks containing different poultry and ornamental bird species. Most of the affected premises were detected during the implementation of the national AI monitoring plan and at the time of sampling none of the birds showed any symptoms. Epidemiological investigations revealed commercial links (movement of live birds) between 8 of these farms. From 22 August to 2 October 2007 six infected meat turkey farms were identified in the Lombardy Region. These birds showed mild respiratory disease associated with anorexia and a slightly increased mortality rate.
