Data and Tools

The integrated, interdisciplinary science branches of the USGS National Wildlife Health Center (NWHC) develop various data and tools to help understand the dynamics of diseases on wildlife populations. Below are scientific data, data portals, and tools available from the NWHC.

Transcriptional response to West Nile virus infection in the zebra finch (Taeniopygia guttata), a songbird model for immune function

The data set contains paired-end, 100 nucleotide long RNA sequencing reads for each sample. Raw sequencing reads ranged from 18-30million reads per sample. Quality trimmed reads were mapped to the Zebra Finch reference genome with an average of 79.0-80.8% mapping rate, corresponding to 18,618 Ensembl gene IDs. Of these, 14,114 genes averaged at least 5 mapped reads across all samples

WNS Summer Surveillance: DATA

Bats occupying hibernacula during summer months may play an important role in the epidemiology of white-nose syndrome (WNS). For example, bats exposed to viable Pseudogymnoascus destructans (Pd), the causative agent of WNS, in late summer could spread the fungus by transmitting it to other bats or to other locations suitable for establishment of new environmental reservoirs. To exp

Mortality trends in northern sea otters (Enhydra lutris kenyoni) collected from the coast of Washington and Oregon during 2002—2015: Data

During 2002−2015 we examined the causes of mortality in beachcast northern sea otters (Enhydra lutris kenyoni) collected from the coasts of Washington and Oregon states. A total of 333 moribund or dead sea otters were reported through opportunistic observations and 93 otter carcasses were collected for necropsy. Retrieved carcasses received a full diagnostic evaluation to determine ca

Emerging fungal pathogen Ophidiomyces ophiodiicola in wild European snakes: data

Snake fungal disease (SFD) is an emerging disease of wild snakes in eastern North America caused by the fungus Ophidiomyces ophiodiicola. Recently, the disease has also been detected in wild snake in Europe. The data presented here describe: 1) culture, PCR, and histopathology results of wild European snakes opportunistically sampled for O. ophiodiicola, 2) colony expansion rate

Puffer Mortality Data

In 2010, a mass mortality of pufferfish in Hawaii was dominated by Arothron hispidus showing aberrant neurological behaviors. Using pathology, toxinology, and field surveys, we implicated a series of novel, polar, marine toxins as a likely cause of this mass mortality. Our findings are striking in that 1) a marine toxin was associated with a kill of a fish species that is, itse

Susceptibility and antibody response of the laboratory model zebra finch (Taeniopygia guttata) to West Nile Virus: Data

The data set contains the results of experimental challenge of captive zebra finches with an American crow isolate of West Nile virus (WNV). Data include infectivity, mortality, viremia, oral shedding of virus, and serology for anti- WNV antibodies. Australian and Timor zebra finches were used in this study and both are useful as a laboratory model of an avian species with moderate su

Serum biochemistries of Pacific black brant

The data set contains results for nine serum biochemistries in molting Pacific black brant (Branta bernicla nigricans). These data were used to calculate reference intervals (sometimes referred to as normal values) for the nine serum biochemistries. All brant were after-hatch year. All samples were collected in 2006 and 2007 in the Teshekpuk Lake Special Area, Alaska.

Snake fungal disease: an emerging threat to wild snakes

Snake fungal disease (SFD) is an emerging disease of wild snakes in eastern North America caused by the fungus Ophidiomyces ophiodiicola. The data presented here describe: 1) the types of fungi recovered in culture from the skin of snakes with and without fungal skin infections, 2) the presence or absence of skin lesions in populations of snakes surveyed at several sites in Wisconsin

Prevalence of West Nile virus in migratory birds during spring and fall migration, 2001-2003

To investigate the role of migratory birds in the dissemination of West Nile virus (WNV), we measured the prevalence of infectious WNV and specific WNV neutralizing antibodies in birds, principally Passeriformes, during spring and fall migrations in the Atlantic and Mississippi flyways from 2001-2003. Blood samples were obtained from 13,403 birds, representing 133 species. Specific

Seroprevalence of West Nile virus in feral horses on Sheldon National Wildlife Refuge, Nevada, United States 2004-2006, 2008 and 2009

The authors screened 1,397 feral horses (Equus caballus) on Sheldon National Wildlife Refuge, Nevada, United States, for IgM and IgG against flavivirus during 2004-2006, 2008, and 2009. Positive serum samples were tested for neutralizing antibodies to West Nile virus (WNV) and St. Louis encephalitis virus (SLEV). One animal was positive for antibody against WNV in 2004,

Avian botulism type E in waterbirds of Lake Michigan, 2010-2013

During 2010 to 2013, waterbird mortality surveillance programs used a shared protocol for shoreline walking surveys performed June to November at three areas in northern Lake Michigan. In 2010 and 2012, 1244 total carcasses (0.8 dead bird/km walked) and 2399 total carcasses (1.2 dead birds/km walked), respectively, were detected. Fewer carcasses were detected in 2011 (353 to

Temperature-dependent growth of Geomyces destructans, the fungus that causes bat white-nose syndrome

White-nose syndrome (WNS) is an emergent disease estimated to have killed over five million North American bats. Caused by the psychrophilic fungus Geomyces destructans, WNS specifically affects bats during hibernation. We describe temperature-dependent growth performance and morphology for six independent isolates of G. destructans from North America and Europe. Thermal performance curves
