Trim21 Regulates Nmi-Ifi35 Complex-Mediated Inhibition Of Innate Antiviral Response, Anshuman Das, Phat X. Dinh, Asit K. Pattnaik Sep 2015

Trim21 Regulates Nmi-Ifi35 Complex-Mediated Inhibition Of Innate Antiviral Response, Anshuman Das, Phat X. Dinh, Asit K. Pattnaik

School of Veterinary and Biomedical Sciences: Faculty Publications

In this study, using an immunoprecipitation coupled with mass spectrometry approach, we have identified the E3 ubiquitin ligase Trim21 as an interacting partner of IFI35 and Nmi. We found that this interaction leads to K63-linked ubiquitination on K22 residue of Nmi, but not IFI35. Using domain deletion analysis, we found that the interaction is mediated via the coiled-coil domain of Nmi and the carboxyl-terminal SPRY domain of Trim21. Furthermore, we show that depletion of Trim21 leads to significantly reduced interaction of Nmi with IFI35, which results in the abrogation of the negative regulatory function of the Nmi-IFI35 complex on innate …

The Thai Journal of Veterinary Medicine

Tembusu virus (TMUV) namely KPS54A61 has spread in duck farms in many provinces in Thailand since 2010. The morbidity ranges from 15-30% and the mortality ranges from 10-15%. All infected ducks exhibit nervous signs including ataxia and paralysis. TMUV was successfully isolated from the brain and spinal cord of infected ducks by using C6/36 and Vero cells, but the typical cytopathic effect (CPE) was presented in the Vero cells only. Phylogenetic analysis of the whole genomic sequence of our TMUV-KPS54A61 virus showed that it belonged to the Ntaya virus group of Flaviviridae and its genomic sequence was similar to that …

Development Of An Indirect Elisa, Blocking Elisa, Fluorescent Microsphere Immunoassay And Fluorescent Focus Neutralization Assay For Serologic Evaluation Of Exposure To North American Strains Of Porcine Epidemic Diarrhea Virus, Faten Okda, Xiaodong Liu, Aaron Singrey, Travis Clement, Julie Nelson, Jane Christopher-Hennings, Eric A. Nelson, Steven Lawson

Veterinary and Biomedical Sciences Faculty Publications

Recent, severe outbreaks of porcine epidemic diarrhea virus (PEDV) in Asia and North America highlight the need for well-validated diagnostic tests for the identification of PEDV infected animals and evaluation of their immune status to this virus. PEDV was first detected in the U.S. in May 2013 and spread rapidly across the country. Some serological assays for PEDV have been previously described, but few were readily available in the U.S. Several U.S. laboratories quickly developed indirect fluorescent antibody (IFA) assays for the detection of antibodies to PEDV in swine serum, indicating prior exposure. However, the IFA has several disadvantages, including …

Variation In Brain Morphology Of Intertidal Gobies: A Comparison Of Methodologies Used To Quantitatively Assess Brain Volumes In Fish, Gemma E. White, Culum Brown Aug 2015

Variation In Brain Morphology Of Intertidal Gobies: A Comparison Of Methodologies Used To Quantitatively Assess Brain Volumes In Fish, Gemma E. White, Culum Brown

Veterinary Science and Medicine Collection

When correlating brain size and structure with behavioural and environmental characteristics, a range of techniques can be utilised. This study used gobiid fishes to quantitatively compare brain volumes obtained via three different methods; these included the commonly used techniques of histology and approximating brain volume to an idealised ellipsoid, and the recently established technique of X-ray micro-computed tomography (micro-CT). It was found that all three methods differed significantly from one another in their volume estimates for most brain lobes. The ellipsoid method was prone to over- or under-estimation of lobe size, histology caused shrinkage in the telencephalon, and although micro-CT …

Repurposing Celecoxib As A Topical Antimicrobial Agent, Shankar Thangamani, Waleed Younis, Mohamed N. Seleem Jul 2015

Repurposing Celecoxib As A Topical Antimicrobial Agent, Shankar Thangamani, Waleed Younis, Mohamed N. Seleem

Department of Comparative Pathobiology Faculty Publications

There is an urgent need for new antibiotics and alternative strategies to combat multidrug-resistant bacterial pathogens, which are a growing clinical issue. Repurposing existing approved drugs with known pharmacology and toxicology is an alternative strategy to accelerate antimicrobial research and development. In this study, we show that celecoxib, a marketed inhibitor of cyclooxygenase-2, exhibits broad-spectrum antimicrobial activity against Gram-positive pathogens from a variety of genera, including Staphylococcus, Streptococcus, Listeria, Bacillus, and Mycobacterium, but not against Gram-negative pathogens. However, celecoxib is active against all of the Gram-negative bacteria tested, including strains of, Acinetobacter, and Pseudomonas, when …

Diffusion Tensor Imaging Of Dolphin Brains Reveals Direct Auditory Pathway To Temporal Lobe, Gregory S. Berns, Peter F. Cook, Sean Foxley, Saad Jbabdi, Karla L. Miller, Lori Marino Jul 2015

Diffusion Tensor Imaging Of Dolphin Brains Reveals Direct Auditory Pathway To Temporal Lobe, Gregory S. Berns, Peter F. Cook, Sean Foxley, Saad Jbabdi, Karla L. Miller, Lori Marino

Veterinary Science and Medicine Collection

The brains of odontocetes (toothed whales) look grossly different from their terrestrial relatives. Because of their adaptation to the aquatic environment and their reliance on echolocation, the odontocetes’ auditory system is both unique and crucial to their survival. Yet, scant data exist about the functional organization of the cetacean auditory system. A predominant hypothesis is that the primary auditory cortex lies in the suprasylvian gyrus along the vertex of the hemispheres, with this position induced by expansion of ‘associative0 regions in lateral and caudal directions. However, the precise location of the auditory cortex and its connections are still unknown. Here, …

Maxwell H. Gluck Equine Research Center Faculty Publications

Strongylus vulgaris is the most pathogenic nematode parasite of horses. Its extensive migration in the mesenteric blood vessels can lead to life-threatening intestinal infarctions. Recent work has shown that this parasite is still identified among managed horse populations. A serum enzyme-linked immunosorbent assay (ELISA) has been developed for the detection of migrating larvae of S. vulgaris. Previous work has documented an increase in ELISA values following larvicidal treatment with ivermectin and suggested that the target parasite antigen is primarily produced by the later larval stages. The aim of this study was to experimentally inoculate cohorts of foals with S. …

Annotation Of The Protein Coding Regions Of The Equine Genome, Matthew S. Hestand, Theodore S. Kalbfleisch, Stephen J. Coleman, Zheng Zeng, Jinze Liu, Ludovic Orlando, James N. Macleod

Veterinary Science Faculty Publications

Current gene annotation of the horse genome is largely derived from in silico predictions and cross-species alignments. Only a small number of genes are annotated based on equine EST and mRNA sequences. To expand the number of equine genes annotated from equine experimental evidence, we sequenced mRNA from a pool of forty-three different tissues. From these, we derived the structures of 68,594 transcripts. In addition, we identified 301,829 positions with SNPs or small indels within these transcripts relative to EquCab2. Interestingly, 780 variants extend the open reading frame of the transcript and appear to be small errors in the equine …

Maxwell H. Gluck Equine Research Center Faculty Publications

The reference assembly for the domestic horse, EquCab2, published in 2009, was built using approximately 30 million Sanger reads from a Thoroughbred mare named Twilight. Contiguity in the assembly was facilitated using nearly 315 thousand BAC end sequences from Twilight's half brother Bravo. Since then, it has served as the foundation for many genome-wide analyses that include not only the modern horse, but ancient horses and other equid species as well. As data mapped to this reference has accumulated, consistent variation between mapped datasets and the reference, in terms of regions with no read coverage, single nucleotide variants, and small …

SIUE Faculty Research, Scholarship, and Creative Activity

The human head louse is a cosmopolitan ectoparasite and frequently infests many people, particularly school-age children. Due to widespread pyrethroid resistance and the lack of efficient resistance management, there has been a considerable interest in the protection of uninfested people and prevention of reinfestation by disrupting lice transfer. In this study, two nonclinical model systems (in vitro and in vivo) were used to determine the efficacy of the infestation deterrents, Elimax lotion and Elimax shampoo, against human head lice or poultry chewing lice, respectively. With in vitro assessments, female head lice exhibited significantly higher avoidance responses to hair tufts treated …

Escherichia coli strains from dogs with different clinical signs were studied for their antimicrobial sensitivity profiles, extended spectrum beta-lactamase enzymes, and virulent genes. The 364 E. coli isolates originated from the skin (32.48%), urinary tract (31.32%), gastrointestinal tract (16.21%), reproductive system (7.69%), ear (6.05%), respiratory tract (4.94%), and other specimens (1.37%). Using the disk diffusion method, the E. coli were resistant to amoxicillin, amoxicillin-clavulanic acid, azithromycin, cephalexin, ceftriaxone, ciprofloxacin, doxycycline, enrofloxacin, norfloxacin, gentamicin, and sulfamethoxazole/trimethoprim at the rates of 84, 36, 41, 57, 38, 66, 73, 70, 64, 47, and 64%, respectively. Ninety-seven E. coli that were resistant to two …
