Transcriptional response to West Nile virus infection in the zebra finch (Taeniopygia guttata), a songbird model for immune function
공공데이터포털
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.
Susceptibility and antibody response of the laboratory model zebra finch (Taeniopygia guttata) to West Nile Virus: Data
공공데이터포털
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.
Prevalence of West Nile virus in migratory birds during spring and fall migration, 2001-2003
공공데이터포털
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 WNV neutralizing antibody was detected in 254 resident and migratory birds, representing 39 species, and was most commonly detected in northern cardinals ( Cardinalis cardinalis ) (9.8%, N = 762) and gray catbirds ( Dumetella carolinensis ) (3.2%, N = 3188). West Nile virus viremias were detected in 19 birds, including 8 gray catbirds, and only during the fall migratory period. These results provide additional evidence that migratory birds may have been a principal agent for the spread of WNV in North America and provide data on the occurrence of WNV in a variety of bird species.
Lung Transcriptome of Newcastle Disease Virus Infected Chickens--Different Immune Response in Two Types of Chicken Dataset
공공데이터포털
Males and females from resistant Fayoumi and susceptible Leghorn chicken lines were either challenged with a lentogenic strain of Newcastle Disease virus or given a mock infection at 3 weeks of age. The lung transcriptomes generated by RNA-sequencing were studied using contrasts across the challenged and non-challenged birds, the two lines, and three time points (2,6, and 10 days post-infection) using Weighted Gene Co-expression Network Analysis (WGNCA).

Seroprevalence of West Nile virus in feral horses on Sheldon National Wildlife Refuge, Nevada, United States 2004-2006, 2008 and 2009
공공데이터포털
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, but all others tested in 2004-2006 were negative. In 2008 and 2009, the authors found evidence of increasing seropositive horses with age, whereas seroprevalence of WNV decreased from 19% in 2008 to 7.2% in 2009. No horses were positive for antibody against SLEV. Being unvaccinated, feral horses can be useful for WNV surveillance.
An examination of the effect of aerosolized Permanone insecticide on zebra finch susceptibility to West Nile virus: Data
공공데이터포털
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 birds (p < 0.001). Our study suggests that exposure to aerosolized Permanone insecticide at levels exceeding typical application rates has the potential to not change or mildly enhance a bird’s resistance to WNV.
Provenance, classification, and abundance of RNA sequence fragments used to assess virus infections in honey bees, Apis mellifera
공공데이터포털
Deformed wing virus (DWV) is a major pathogen of concern to apiculture, and recent reports have indicated the local predominance and potential virulence of recombinants between DWV and a related virus, Varroa destructor virus 1 (VDV). However, little is known about the frequency and titer of VDV and recombinants relative to DWV generally. In this study, I assessed the relative occurrence and titer of DWV and VDV in public RNA-seq accessions of honey bee using a rapid, kmer-based approach. Three recombinant types were detectable graphically and corroborated by de novo assembly. Recombination breakpoints did not disrupt the capsid-encoding region, consistent with previous reports, and both VDV- and DWV-derived capsids were observed in recombinant backgrounds. High abundance of VDV kmers was largely restricted to recombinant forms. Non-metric multidimensional scaling identified genotypic clusters among DWV isolates, which was corroborated by read mapping and consensus generation. The recently described DWV-C lineage was not detected in the searched accessions. The data further highlight the utility of high-throughput sequencing to monitor viral polymorphisms and statistically test biological predictors of titer, and point to the need for consistent methodologies and sampling schemes.
Arumowot Virus Ar 1286‐64 Complete RNA Gene Sequence: L, M, and S Segments from GenBank
공공데이터포털
The University of Texas at El Paso (UTEP) was awarded a 5 year Cooperative Agreement in September, 2013 to develop and evaluate the Rift Valley Fever (RVF) MP‐12 and derivative vaccine candidates for protecting livestock in Tanzania. Animals like cattle, goat and sheep play a major role in initiating and maintaining the RVF epidemic transmission cycle. This project proposed developing RVF arMP12‐NSm‐del as a Differentiating Infected from Vaccinated Animals (DIVA) animal vaccine for use in Africa to help prevent outbreaks and spread of RVF by vaccination of animals in endzootic zones. This will help reduce the human exposure to the disease and is expected to improve overall public health and reduce economic losses by limiting the extent, severity and duration of an outbreak.
