Dataset: Mortality trends in the Washington population of northern sea otters (Enhydra lutris kenyoni) during 2002—2015

These data document cause of death determination for stranded otters salvaged from the coast of Washington state and northern Oregon for post-mortem analysis.

SPV field trials bait uptake data

These data were collected as part of a field trial to test the effectiveness of a sylvatic plague vaccine (see Rocke et al., 2017 for details). Vaccine and control plots were selected randomly from the available pairs at each location. Baits containing Rhodamine B, a biomarker, were distributed at each plot. At least 1 week and no more than 2 months post-baiting each year, local collaborators cap

Emerging fungal pathogen Ophidiomyces ophiodiicola in wild European snakes

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 rates of various isolat

Environmental conditions synchronize waterbird mortality events in the Great Lakes: Data

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. Timing (to day) and location (to transect) of carcass deposition and species affected were summarized. Using these observations, the broader goal of our study was to quantify the spatial synchrony of avian mortality

Determinants of Pseudogymnoascus destructans within bat hibernacula: data

This dataset includes data used to summarize trends and identify best-fit models to explain patterns in presence-absence and abundance of Pseudogymnoascus destructans (Pd) in environmental substrates and on bats within six bat hibernacula at different stages of white-nose syndrome (WNS). Data relating to environmental substrates include: dates and relative spatial locations of samples collected wi

An examination of the effect of aerosolized Permanone insecticide on zebra finch susceptibility to West Nile virus

Following building an aerosol exposure chamber in which we could expose domesticated zebra finches, we examined the effects of exposure to aerosolized Permanone® 30:30 insecticide (permethrin and piperonyl butoxide in soy oil vehicle) at ~103-106 x potential environmental concentrations on the response to experimental challenge with West Nile virus (WNV). Compared to vehicle control birds, WNV out

Pathogenic lineage of Perkinsea causes mass mortality of frogs across the USA: Data

Severe perkinsea data was based on the observation of characteristic gross and microscopic lesions and the morphological identification of Perkinsea organisms within the lesions. Necropsies and gross evaluation of carcasses were carried out under a dissecting microscope. Specimen were collected and submitted to the NWHC as part of mortality investigations and collection of specimen from apparently

Monkeypox challenge of rope squirrels: data

Monkeypox virus (MPXV) is a zoonotic disease endemic in Central and West Africa and is the most virulent orthopoxvirus affecting humans since the eradication of variola virus (VARV). In order to assess their reservoir potential, wild-caught rope squirrels were experimentally infected via intranasal and intradermal exposure with a recombinant MPXV strain from Central Africa engineered to express th

Natural infections with Pigeon Paramyxovirus-1: Pathologic changes in Eurasian collared-doves (Streptopelia decaocto) and rock pigeons (Columba livia) in the USA: Data

We reviewed pathological findings and to a lesser extent epidemiological data from 70 free-ranging columbiforms naturally infected with Pigeon paramyxovirus-1 (PPMV-1) from 25 different PPMV-1 mortality events in columbiforms in the USA. In a subset of 17 birds from 10 of the studied outbreaks, we carried out immunohistochemistry targeting PPMV-1 nucleoprotein to determine the tissue distribution

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 explore risks for

Field efficacy trials with sylvatic plague vaccine

These data were collected as part of a field trial to test the efficacy of a sylvatic plague vaccine. Treatment and control sites were selected randomly from the available sites at each location. Site pairs were a minimum of 20 acres, (with a few exceptions). Prairie dog trapping took place a minimum of two weeks post-baiting and trapping procedures were approved by the NWHC Animal Care and Use

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

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 and were util
