APMV-1 is the cause of Newcastle disease in poultry, a major economic issue for farmers. This makes this recent finding of particular significance - finding APMV-1 sublin 4a (rather than the usual pigeon form 4b). This finding was in Italy, and much more work will need to be done to assess how widespread geographically this is, and which other species may be affected.
This underlines the importance of good hygiene at the birdtable, and not just to prevent Trichomonas! Look at Ark-Klens and Citrosan.
