biologic and molecular characteristics of toxoplasma gondii isolates from striped skunk (mephitis mephitis), canada goose (branta canadensis), black-winged lory (eos cyanogenia), and cats (felis catus).	toxoplasma gondii isolates can be grouped into 3 genetic lineages. type i isolates are considered virulent to outbred mice, whereas type ii and iii isolates are not. in the present report, viable t. gondii was isolated for the first time from striped skunk (mephitis mephitis), canada goose (branta canadensis), and black-winged lory (eos cyanogenia). for the isolation of t. gondii, tissues were bioassayed in mice, and genotyping was based on the sag2 locus. toxoplasma gondii was isolated from 3 o ...	2004	15562622
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 ...	2006	17092880
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 ...	2008	18568663
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 ...	2009	19929736
