Carol Cardona and Zheng Xing had Research article published in Journal of Virology
 

A novel mechanism of viral evasion of host innate immunity is unveiled in a research article, “Evasion of Antiviral Immunity by Sequestration of TBK1/IKK¤Á/IRF3 into Viral Inclusion Bodies,” in the March issue of Journal of Virology. The finding, reported by Dr. Zheng Xing, associate professor, Dr. Carol Cardona, professor, and their team, demonstrates that inclusion bodies, the unique structure that forms in virus-infected cells, could be used by viruses to sequester signaling components, critical in the induction of antiviral interferons. The article was selected by the editors of Journal of Virology as an "article of significant interest" and recommended to Faculty of 1000 (F1000) Prime Report by Professor Grant McFadden, associate editor of PLoS Pathogen.
 

Functions of inclusion bodies in immune regulation are not well understood. Dr. Xing’s group found that the nonstructural protein NSs of a new bunyavirus, severe fever with thrombocytopenia syndrome virus, forms inclusion bodies in infected cells. Interestingly, NSs interacts with TBK1, a key kinase in the interferon (IFN) signaling pathway, and sequesters IKKε and IRF3 as well as TBK1 into inclusion bodies. As a result, the activated IRF3, a transcription factor, fails to be translocated into the nucleus, IFN-β induction is compromised and viral replication increased, providing a new mechanism of viral immune evasion.

Timothy Johnson, Carol Cardona, and colleagues explore light turkey syndrome in PeerJ article

A collaborative research team led by Dr. Tim Johnson (CVM), Dr. Carol Cardona (CVM), and Dr. Sally Noll (Animal Science) recently published "Succession of the Turkey Gastrointestinal Bacterial Microbiome Related to Weight Gain" in the peer-reviewed, open-access journal PeerJ. This work is part of a project funded by the Minnesota Turkey Research and Promotion Council aimed at "light turkey syndrome," a widespread, multimillion-dollar problem affecting commercial turkey growers in Minnesota. Characterized by lower weight in market-age turkeys, light turkey syndrome does not appear to involve a known bacterial or viral pathogen. To better understand the syndrome, Tim and his team are working in collaboration with the turkey industry to study the totality of healthy bacteria in the turkey gut, also known as the microbiome. In the PeerJ article, they identify a number of bacteria that are defining markers of the succession of bacteria in the turkey gut. These bacteria changed earlier in heavier-weight turkey flocks than they did in flocks of lower weights. What's next? The team is working to identify ways to modulate the turkey gut microbiome early in a bird's life, in the hope of resolving light turkey syndrome. Researchers are using DNA sequencing-based approaches to identify antibiotic-free ways to improve gut health and weight gain in turkeys.

U of M, Virgina Tech awarded grant to complete sequencing of turkey genome


The U.S. Department of Agriculture has awarded a two-year, $908,280 grant to the University of Minnesota Department of Veterinary and Biomedical Sciences and Virginia Tech to finish sequencing the genome of the domesticated turkey, Meleagris gallopavo. The funding will be used by the Turkey Genome Sequencing Consortium to complete the genome sequencing using next-generation sequencing platforms, assemble the genome sequence, and identify genes and functions in the final genome sequence by use of a sophisticated annotation pipeline. The award will also help establish a bioinformatics and comparative genome resource for both chicken and turkey.   The consortium, which includes Dr. Kent Reed, associate professor in the Department of Veterinary and Biomedical Sciences, has generated about 90 percent of the sequence necessary for the project. The data will be released to GenBank in the near future.

 


 

U Of M Researchers Get Grant To Study Turkey DNA


Minnesota is the largest producer of turkeys nationwide.  WCCO highlighted the research of Dr. Kent Reed, "{We} essentially make turkeys healthier so we can have less antibiotics in the system, just breeding better birds. One of the things we work on is muscle development, and structure and that has to do with meat quality, taste for example. The more you know about the genome, the more you can do."

A canine DNM1 mutation is highly associated with the syndrome of exercise-induced collapse

 

pp1235-1239
Edward E Patterson, Katie M Minor, Anna V Tchernatynskaia, Susan M Taylor, G Diane Shelton, Kari J Ekenstedt & James R Mickelson.

Edward Patterson and colleagues report that a missense mutation in the gene encoding dynamin 1 (DNM1) is associated with exercised-induced collapse in Labrador retriever dogs. This is the first documented mutation in DNM1 in mammals and suggests a critical role for dynamin 1 in maintaining proper neurotransmission under conditions of high synaptic activity.

 


 

Officials seek limits on livestock antibiotics


Proposals to ban the use of antibiotics as a livestock growth promotant could drive up farmers costs without improving public health, skeptical lawmakers said on Wednesday…Although Danish Veterinary and Food Administrator Per Henriksen said the Danish experience yielded good results, Randall Singer, associate professor of epidemiology at the University of Minnesota College of Veterinary Medicine, pointed out that livestock health suffered in Denmark after the ban.
