synanthropic flies as vectors of cryptosporidium and giardia among livestock and wildlife in a multispecies agricultural complex.the capacity of synanthropic flies belonging to the families calliphoridae, sarcophagidae, and muscidae to serve as mechanical vectors of cryptosporidium and giardia among livestock and wildlife in a multispecies agricultural complex in northwest georgia (usa) was studied using fluorescent in situ hybridization (fish) and immunofluorescent antibody (ifa) techniques. flies from all three families were carrying viable cryptosporidium oocysts and giardia cysts internally and externally, and deposit ...200717979535
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
canada geese and the epidemiology of avian influenza viruses.canada geese (branta canadensis) are numerous, highly visible, and widely distributed in both migratory and resident populations in north america; as a member of the order anseriformes, they are often suggested as a potential reservoir and source for avian influenza (ai) viruses. to further examine the role of canada geese in the ecology of ai, we re-evaluated existing literature related to ai virus in this species and tested breeding populations of canada geese from three states (georgia, west ...201020688710
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
free-living canada geese and antimicrobial resistance.we describe antimicrobial resistance among escherichia coli isolated from free-living canada geese in georgia and north carolina (usa). resistance patterns are compared to those reported by the national antimicrobial resistance monitoring system. canada geese may be vectors of antimicrobial resistance and resistance genes in agricultural environments.200515963291
antibodies to avian influenza viruses in canada geese (branta canadensis): a potential surveillance tool?traditionally, the epidemiology of avian influenza viruses (aivs) in wild birds has been defined by detection of virus or viral rna through virus isolation or reverse-transcription polymerase chain reaction. our goals were to estimate aiv antibody prevalence in canada geese (branta canadensis) and measure effects of age and location on these estimates. we collected 3,205 samples from nine states during june and july 2008 and 2009: georgia, massachusetts, minnesota, mississippi, new jersey, north ...201223060517
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
