Some parasitic and infectious diseases in waterfowl in Oklahoma.
Blood films and serum samples from free-ranging waterfowl wintering in and migrating through Oklahoma were examined for hematozoa and tested for antibody responses to Newcastle disease virus (NDV) and type-A influenza. One-hundred-eleven of 728 birds (15.24%) were positive for 1 or more hematozoa. Serologic testing revealed 11 of 280 (3.93%) positive for antibody to NDV and 5 of 171 (2.95%) positive for antibody to type-A influenza.
