Genetic diversity and mutation of avian paramyxovirus serotype 1 (Newcastle disease virus) in wild birds and evidence for intercontinental spread Genetic diversity and mutation of avian paramyxovirus serotype 1 (Newcastle disease virus) in wild birds and evidence for intercontinental spread
Avian paramyxovirus serotype 1 (APMV-1), or Newcastle disease virus, is the causative agent of Newcastle disease, one of the most economically important diseases for poultry production worldwide and a cause of periodic epizootics in wild birds in North America. In this study, we examined the genetic diversity of APMV-1 isolated from migratory birds sampled in Alaska, Japan, and Russia...

Pathogen exposure and blood chemistry in the Washington population of northern sea otters (Enhydra lutris kenyoni) Pathogen exposure and blood chemistry in the Washington population of northern sea otters (Enhydra lutris kenyoni)
Northern sea otters (Enhydra lutris kenyoni) from Washington State, United States were evaluated in 2011 to determine health status and pathogen exposure. Antibodies to Brucella spp. (10%) and influenza A virus (23%) were detected for the first time in this population in 2011. Changes in clinical pathology values (serum chemistries), exposure to pathogens, and overall health of the...

Genomic analysis of avian influenza viruses from waterfowl in Western Alaska, USA Genomic analysis of avian influenza viruses from waterfowl in Western Alaska, USA
The Yukon-Kuskokwim Delta (Y-K Delta) in western Alaska is an immense and important breeding ground for waterfowl. Migratory birds from the Pacific Americas, Central Pacific, and East Asian-Australasian flyways converge in this region, providing opportunities for intermixing of North American- and Eurasian-origin hosts and infectious agents, such as avian influenza virus (AIV). We...

Evolution of a reassortant North American gull influenza virus lineage: drift, shift and stability Evolution of a reassortant North American gull influenza virus lineage: drift, shift and stability
Background: The role of gulls in the ecology of avian influenza (AI) is different than that of waterfowl. Different constellations of subtypes circulate within the two groups of birds and AI viruses isolated from North American gulls frequently possess reassortant genomes with genetic elements from both North America and Eurasian lineages. A 2008 isolate from a Newfoundland Great Black...

Impacts of migratory Sandhill Cranes (Grus canadensis) on microbial water quality in the central Platte River, Nebraska, USA Impacts of migratory Sandhill Cranes (Grus canadensis) on microbial water quality in the central Platte River, Nebraska, USA
Wild birds have been shown to be significant sources of numerous types of pathogens that are relevant to humans and agriculture. The presence of large numbers of migratory birds in such a sensitive and important ecosystem as the Platte River in central Nebraska, USA, could potentially serve a significant source of bird-derived pathogens in the water/sediment and riverine environment. In...

Evidence that life history characteristics of wild birds influence infection rates and exposure to influenza A viruses Evidence that life history characteristics of wild birds influence infection rates and exposure to influenza A viruses
We report on life history characteristics, temporal, and age-related effects influencing the frequency of occurrence of avian influenza (AI) viruses in four species of migratory geese breeding on the Yukon-Kuskokwim Delta, Alaska. Emperor geese (Chen canagica), cackling geese (Branta hutchinsii), greater white-fronted geese (Anser albifrons), and black brant (Branta bernicla), were all...
