Background: We recently reported the identification of Bacillus sp. NRRL B-14911 that induces heart autoimmunity by generating cardiac-reactive T cells through molecular mimicry. This marine bacterium was originally isolated from the Gulf of Mexico, but no associations with human diseases were reported. Therefore, to characterize its biological and medical significance, we sought to determine and analyze the complete genome sequence of Bacillus sp. NRRL B-14911.

Results: Based on the phylogenetic analysis of 16S ribosomal RNA (rRNA) genes, sequence analysis of the 16S-23S rDNA intergenic transcribed spacers, phenotypic microarray, and matrix-assisted laser desorption ionization time-offlight mass spectrometry, we propose that this ...

Plants, Prions And Possibilities: Current Understanding And Significance Of Prion Uptake Into Plants, Tracy A. Nichols 2016 U.S. Department of Agriculture

Plants, Prions And Possibilities: Current Understanding And Significance Of Prion Uptake Into Plants, Tracy A. Nichols

USDA National Wildlife Research Center - Staff Publications

Chronic wasting disease (CWD) is an infectious, neurodegenerative disease of deer (white-tailed and mule), elk, moose, sika deer and muntjac caused by a misfolded version of a normally occurring protein. The notion that CWD could be spread indirectly via the environment has been documented and accepted in the scientific community for quite some time. Deer and elk consume soil, inhale dust and lick objects that have infectious material on them, resulting in chronic, low dose exposure. Surface contamination of plants with urine or feces is likely an additional source of exposure via ingestion and has been modeled in the laboratory ...


Identification Of Feline Tritrichomonas Foetus Surface Epitopes: Putative Targets For Development Of A Novel Diagnostic Test For Feline Trichomonosis, Emily Nissa Gould 2016 University of Tennessee - Knoxville

Identification Of Feline Tritrichomonas Foetus Surface Epitopes: Putative Targets For Development Of A Novel Diagnostic Test For Feline Trichomonosis, Emily Nissa Gould

Masters Theses

BACKGROUND: Tritrichomonas foetus (T. foetus) is a flagellated protozoa that infects the distal ileum and proximal colon of domestic cats and also induces reproductive failure in cattle. Although feline trichomonosis is recognized to have a global prevalence of up to 30%, it still poses a diagnostic and therapeutic challenge to veterinarians; thus, there is a need for both improved diagnostics and therapeutics. Despite differing organ tropism between genotypes, evidence exists for conserved virulence factors between feline and bovine T. foetus. Two epitopes (1.15 and 1.17) of the bovine T. foetus glycosylated surface antigen 1.15-1.17 have been ...


Variation In Avian Pathogenic Escherichia Coli Colonization Levels In Chickens, Melissa Monson, Michael Kaiser, Susan Lamont 2016 Iowa State University

Variation In Avian Pathogenic Escherichia Coli Colonization Levels In Chickens, Melissa Monson, Michael Kaiser, Susan Lamont

Melissa Monson

Colonization levels in five tissues after avian pathogenic Escherichia coli (APEC) inoculation were investigated in chickens to generate phenotypic data for a genome wide association study (GWAS). Bacterial loads were measured in 370 birds and varied among individuals and tissues. Mean bacterial levels were significantly different between tissues (right lung > spleen > left lung and liver > blood). There were also significant correlations in bacterial load between tissues. These data suggest that colonization levels could be used as phenotypes in GWAS and could help identify markers associated with poultry resistance to APEC infections. After verification, these markers could be used for genetic ...

Noninvasive Assessment Of Cardiac Abnormalities In Experimental Autoimmune Myocarditis By Magnetic Resonance Microscopy Imaging In The Mouse, Chandirasegaran Massilamany, Vahid Khalilzad-Sharghi, Arunakumar Gangaplara, David Steffen, Shadi F. Othman, Jay Reddy

Jay Reddy Publications

Myocarditis is an inflammation of the myocardium, but only ~10% of those affected show clinical manifestations of the disease. To study the immune events of myocardial injuries, various mouse models of myocarditis have been widely used. This study involved experimental autoimmune myocarditis (EAM) induced with cardiac myosin heavy chain (Myhc)-α 334-352 in A/J mice; the affected animals develop lymphocytic myocarditis but with no apparent clinical signs. In this model, the utility of magnetic resonance microscopy (MRM) as a non-invasive modality to determine the cardiac structural and functional changes in animals immunized with Myhc-α 334-352 is shown. EAM and ...


Infection Of Commercial Laying Hens With Newcastle Disease Virus: Differing Responses Between Birds Provide Potential For Genetic Improvement Through Selection, Kaylee Rowland, Huaijun Zhou, Rodrigo Gallardo, David Bunn, Susan J. Lamont 2016 Iowa State University

Infection Of Commercial Laying Hens With Newcastle Disease Virus: Differing Responses Between Birds Provide Potential For Genetic Improvement Through Selection, Kaylee Rowland, Huaijun Zhou, Rodrigo Gallardo, David Bunn, Susan J. Lamont

Animal Industry Report

Exotic Newcastle Disease Virus (ENDV) cause extremely rapid mortality in chickens after exposure to the virus. People rely heavily on poultry to provide protein and income in many places where NDV is not effectively controlled through vaccination and biosecurity. Losses from NDV contribute to worldwide hunger and poverty. It may be possible to use genetic selection to produce chickens that have a stronger immune response in the face of NDV challenge. For genetic selection to be successful, two major elements are required: differences in immune response among chickens and genetic control of these differences. This study clearly demonstrated the existence ...


Meningeal Worm In Central Iowa Goat Herds, Kelly Still Brooks 2016 Iowa State University

Meningeal Worm In Central Iowa Goat Herds, Kelly Still Brooks

Animal Industry Report

Aberrant migration of the deer meningeal worm, Parelaphostrongylus tenuis, is a commonly recognized cause of neurologic disease in South American camelids but is less frequently considered in other small ruminant species. After an unusually cool and wet summer season, central Iowa goat herds serviced by Iowa State University’s Veterinary Field Services have been increasingly affected by P. tenuis, with clinical cases presenting as early as August. Most caprine cases present with progressive neurologic deficits, starting with hind-end weakness and ataxia which may lead to complete paresis and death. Both sporadic cases and herd outbreaks involving as much as 15 ...

The probability of detecting influenza A virus (IAV) in oral fluid (OF) specimens was calculated for each of 13 assays based on real-time reverse-transcription polymerase chain reaction (rRT-PCR) and 7 assays based on virus isolation (VI). The OF specimens were inoculated with H1N1 or H3N2 IAV and serially diluted 10-fold (10(-1) to 10(-8)). Eight participating laboratories received 180 randomized OF samples (10 replicates × 8 dilutions × 2 IAV subtypes plus 20 IAV-negative samples) and performed the rRT-PCR and VI procedure(s) of their choice. Analysis of the results with a mixed-effect logistic-regression model identified dilution and assay as variables ...

Genetic Parameters And Effect Of Wur Genotype On Piglet Response To Co-Infection With Prrs And Pcv2b, With Or Without Vaccination For Prrs, Jenelle R. Dunkelberger, Nick V. L. Serão, Maureen Kerrigan, Joan Lunney, Bob Rowland, Jack Dekkers

Animal Industry Report

Commercial crossbred nursery piglets were either vaccinated or not using a modified live porcine reproductive and respiratory syndrome (PRRS) virus vaccine and all pigs were co-infected with PRRS virus (PRRSV) and porcine circovirus type 2b (PCV2b) 28 days later. Genetic correlations indicate that traits associated with primary exposure to PRRSV infection (PRRS viral load (VL) of vaccinated pigs prior to co-infection and PRRS VL of non-vaccinated pigs post co-infection) are genetically the same trait. The WUR single nucleotide polymorphism on chromosome 4, previously associated with reduced PRRS VL under PRRSV-only infection, was associated with significantly reduced PRRS VL following vaccination ...


Do Two Distinct Chicken Lines Differ In Their Response To Newcastle Disease Virus?, Melissa S. Herrmann, Rodrigo Gallardo, David A. Bunn, Huaijun Zhou, Susan J. Lamont 2016 Iowa State University

Do Two Distinct Chicken Lines Differ In Their Response To Newcastle Disease Virus?, Melissa S. Herrmann, Rodrigo Gallardo, David A. Bunn, Huaijun Zhou, Susan J. Lamont

Animal Industry Report

The differences between relatively resistant and susceptible chicken lines can be utilized to study the genetics behind disease resistance. To assess resistance, the viral quantity in each bird was measured after challenge with Newcastle Disease Virus (NDV) at two time points. As predicted, the resistant line was able to clear the virus more quickly than the susceptible line. Further studies are needed to determine the genetics responsible for resistance.

Host-Pathogen Protein-Protein Interaction Prediction Using An In Silico Model, John C. F. Hsieh, Robert L. Jernigan, Susan J. Lamont

Animal Industry Report

Newcastle Disease (ND) is caused by Newcastle Disease Virus (NDV) and is a major problem in developing countries where vaccination against NDV is not easily achievable. A step required for NDV infection is the cleavage of the NDV fusion (F) protein. Using structural information of the NDV F protein and the only known host protein binding partner, protein disulfide isomerase A3 (PDIA3), we computer modeled the interaction between the two proteins by looking at a docked structure of these two proteins. With our docked structure, we visualized one of the catalytic domains of PDIA3 being near the cleavage site of ...

Seafood is a highly traded food commodity. Farmed and captured crustaceans contribute a significant proportion with annual production exceeding 10 M metric tonnes with first sale value of $40bn. The sector is dominated by farmed tropical marine shrimp, the fastest growing sector of the global aquaculture industry. It is significant in supporting rural livelihoods and alleviating poverty in producing nations within Asia and Latin America while forming an increasing contribution to aquatic food supply in more developed countries. Nations with marine borders often also support important marine fisheries for crustaceans that are regionally traded as live animals and commodity products ...
