Background: Avian metapneumovirus (aMPV) is one of common respiratory pathogens affects poultry and can cause economic losses, particularly when accompanied with secondary pathogens.
Aim: This study aimed to perform seroprevalence of aMPV for non-vaccinated chicken and duck flocks from six provinces of Egypt (Ash Sharqiyah, Ismailia, Qalyubia, Menufia, Sohaq and North-Sinai) and determine its economic effect.
Methods: Serum samples were collected from non-aMPV vaccinated apparently healthy 40 chicken (23 broilers and 17 layers) and 8 duck (6 Pekin and 2 Muscovy) flocks and then, tested with commercial indirect aMPV ELISA.
Results: Five out of 23 broiler, 6 out of 17 layer, 1 out of 6 Pekin duck and 1 out of 2 Muscovy duck flocks showed positive results. On the other hand, the results showed significant difference in the net profits as a measure of economic impact between infected and non-infected flocks in different provinces.
Conclusion: The results denote that chicken and duck flocks in Egypt were exposed to field strains of aMPV. For our knowledge, aMPV antibodies are detecting in Pekin and Muscovy duck flocks for first time in Egypt.
