migratory birds of central washington as reservoirs of campylobacter jejuni.migratory ducks, canada geese, and sandhill crane from the pacific north american flyway have been screened for campylobacter spp. samples (298) from these birds were examined and the incidence of campylobacter spp. in the samples were as follows: sandhill crane (grus canadensis tabida), 81%; ducks (aythya collaris, anas carolinensis, aythya americana, and anas platyrhynchos), 73%; and canada geese (branta canadensis), 5%. all isolates were identified as campylobacter jejuni. to our knowledge th ...19883378202
response of canada geese to a turf application of diazinon ag500.we investigated the effects of a turf application of the insecticide diazinon ag500 on canada geese (branta canadensis) on a golf course in coastal washington (usa). on both 19 and 26 march 1987, 1 ha of turf on a golf course located in birch bay, washington was treated with diazinon ag500 at a target application rate of 2.2 kg active ingredient per hectare (ai/ha). treated areas were then irrigated with 6 mm water. grass and water samples were collected from three different sites one day before ...19938355349
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
subtype-specific influenza a virus antibodies in canada geese (branta canadensis).historically, surveillance for influenza a viruses (iavs) in wild birds has relied on viral detection assays. this was largely due to poor performance of serological assays in wild birds; however, recently developed commercial serological assays have improved the ability to detect iav antibodies in wild birds. serological surveillance for iav antibodies in canada geese (branta canadensis) has shown that, despite a low prevalence of virus isolations, canada geese are frequently exposed to iavs an ...201525845755
