evidence of avian metapneumovirus subtype c infection of wild birds in georgia, south carolina, arkansas and ohio, usa.metapneumoviruses (mpvs) were first reported in avian species (ampvs) in the late 1970s and in humans in 2001. although ampvs have been reported in europe and asia for over 20 years, the virus first appeared in the united states in 1996, leaving many to question the origin of the virus and why it proved to be a different subtype from those found elsewhere. to examine the potential role of migratory waterfowl and other wild birds in ampv spread, our study focused on determining whether population ...200818568663
cyanobacteria and bmaa: possible linkage with avian vacuolar myelinopathy (avm) in the south-eastern united states.avian vacuolar myelinopathy (avm) is a neurological disease that produces uncoordinated behavior in affected birds in wetland ecosystems of the south-eastern united states. feeding and sentinel trials, field surveys, and genetic studies have implicated the introduced flowering plant species hydrilla verticillata (hydrocharitaceae) and an associated epiphytic cyanobacterial species (order stigonematales) as a causal link to avm. all five morphotypes of cyanobacteria have been shown to produce the ...200919929736
avian vacuolar myelinopathy outbreaks at a southeastern reservoir.avian vacuolar myelinopathy (avm) is a neurologic disease of unknown etiology that affects bald eagles (haliaeetus leucocephalus), american coots (fulica americana), and several species of waterfowl. an unidentified neurotoxin is suspected as the cause of avm, which has been documented at several reservoirs in the southeastern united states. we conducted diagnostic and epidemiologic studies annually during october-march from 1998-2004 at clarks hill/strom thurmond lake on the georgia/south carol ...200617092880
