EnglishThe poultry production sector is tightly centred in Northern Italy, where chickens, turkey and other minor species are reared closely. Among the several well-know and managed respiratory issues, avian Metapneumovirus (aMPV) is growing as a concern also in chicken production, especially in broiler farming. Consistent data on its prevalence are lacking, so aMPV detections were summarized from longitudinal studies and diagnostic one-off samplings from Northern Italy from 2014 to 2016. The results demonstrated the wide circulation of aMPV subtype B and its presence in subsequent cycles in the same farm. aMPV sequences from chickens and turkeys showed high homology from the comparison, excluding a host-based strain separation. A ield vaccination trail was also performed in two aMPV positive farms to verify the beneits of a subtype B-based vaccine administration in broilers, which appeared to fully control the clinical signs even if the persistence of a ield strain was revealed in one of the farms.

| Abstract: | The poultry production sector is tightly centred in Northern Italy, where chickens, turkey and other minor species are reared closely. Among the several well-know and managed respiratory issues, avian Metapneumovirus (aMPV) is growing as a concern also in chicken production, especially in broiler farming. Consistent data on its prevalence are lacking, so aMPV detections were summarized from longitudinal studies and diagnostic one-off samplings from Northern Italy from 2014 to 2016. The results demonstrated the wide circulation of aMPV subtype B and its presence in subsequent cycles in the same farm. aMPV sequences from chickens and turkeys showed high homology from the comparison, excluding a host-based strain separation. A ield vaccination trail was also performed in two aMPV positive farms to verify the beneits of a subtype B-based vaccine administration in broilers, which appeared to fully control the clinical signs even if the persistence of a ield strain was revealed in one of the farms. |
