| the epizootiology of anatid herpesvirus 1 infection in free-flying waterfowl: a comparison of latent and active infections among native waterfowl, captive-reared released ducks, and peridomestic or feral ducks. | the epizootiology of anatid herpesvirus 1 (ahv-1) infection in waterfowl is poorly understood but apparently involves persistence of the virus in latently infected birds. epornitics have often occurred in captive waterfowl or semiwild ducks in parklike settings, and many wildlife professionals conclude that such ducks may be the source of infection for wild waterfowl. we assessed the prevalence of latent infection and viral shedding from four groups of waterfowl: naturally occurring populations ... | 2013 | 23778596 |
| blood parasites of blue-winged teal ( anas discors ) from two migratory corridors, in the southern usa. | we collected 180 blue-winged teal ( anas discors ) in september and october 2002 from florida, us (n=100, representing the eastern migratory corridor) and the louisiana-texas, us, border (n=80, representing the western migratory corridor) and examined for blood parasites using thin heart-blood smears. leucocytozoon simondi, haemoproteus nettionis, and microfilariae were found in 16, 23, and 27 birds, respectively. prevalence of l. simondi and h. nettionis did not vary by migratory corridor, but ... | 2016 | 27285417 |
