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 susceptibility to WNV.
Abstract (from ESA Journals): Climate change is a well-documented driver and threat multiplier of infectious disease in wildlife populations. However, wildlife disease management and climate-change adaptation have largely operated in isolation. To improve conservation outcomes, we consider the role of climate adaptation in initiating or exacerbating the transmission and spread of wildlife disease and the deleterious effects thereof, as illustrated through several case studies. We offer insights into best practices for disease-smart adaptation, including a checklist of key factors for assessing disease risks early in the climate adaptation process. By assessing risk, incorporating uncertainty, planning for change,...

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 utilized for differential expression (DE) analyses. DE analyzed two ways: as pairwise comparisons between treatments to identify specific genes with DEseq2 and as a time course grouping genes into expression paths with EBSeqHMM.
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 outcome was unchanged (65% of birds produced a viremia) in the ‘low’ exposure (9.52 mg/m3±3.13 SD permethrin) group, but reduced in the ‘high’ exposure (mean 376.5 mg/m3±27.9 SD permethrin) group (30% were viremic) (p < 0.05). After clearing WNV infection, birds treated with Permanone regained less body mass than vehicle treated...
Three datasets are included: 1) survival of domesticated canaries and American crows following sub-cutaneous challenges ranging from 101 – 105 plaque forming units of West Nile virus. 2) Arbitrary units of WNV detected by RT-PCR or plaque forming units of WNV cultured in vero cells in 4 separate studies. Culture results are indicated for each day post WNV challenge. 3) Weight (mass) changes in grams in canaries and crows each day following WNV challenge. Day 0 (inoculation) set to 0 gms, then each subsequent day is change in gms from previous day.
