Avian influenza virus investigation on Italian endangered Phasianidae and Tetraonidae populations
The mechanisms of circulation of avian influenza viruses (AIVs) in domestic Galliformes are well-known, however little information is available about AIV ecology in free-living Galliformes populations. This study is aimed to evaluate whether Phasianidae of genus Alectoris and Tetraonidae of genera T...

The mechanisms of circulation of avian influenza viruses (AIVs) in domestic Galliformes are well-known, however little information is available about AIV ecology in free-living Galliformes populations. This study is aimed to evaluate whether Phasianidae of genus Alectoris and Tetraonidae of genera Tetrao and Lagopus may play an active role in AIV ecology in the post-reproductive period. These sedentary species are distributed in post-glacial relict populations threatened by global warming; they live in a snowy mountainous region and are characterised by a social behaviour. In 2003 and 2004, during the September-December periods, 79 wild Galliformes, categorised in age and sex classes, were trapped in the Sondrio Province (Lombardy region, Central Alps, Northern Italy); sampling area was place at altitudes between 1400 and 3000 m a.s.l.
