Dr. Stewart Gardner, post doctoral fellow in the School of Veterinary Medicine and Biomedical Sciences, will present "Understanding Phosphate signaling in Esherichia coli and characterization of Staphylococcus aureus Vancomycin resistant strains" Feb. 15 in VBS 145 at 4 p.m.

Phosphate is an essential molecule of life. Many bacteria, including E. coli, adapt their physiology to changes in the availability of phosphate. This adaptation is mediated by a two-component regulatory system comprised of PhoR and PhoB. PhoR is a histidine kinase that phosphorylates PhoB, the response regulator. When PhoB is phosphorylated, it activates transcription of genes in the Pho regulon that allow the cell to transport and utilize phosphate more efficiently; however, the mechanism for sensing phosphate is unknown. It was suggested that a phosphate transporter, PstSCAB, in concert with the negative regulator PhoU function as a phosphate sensor. Gardner's work to identify and characterize PhoU’s function suggests that a regulatory complex responds to phosphate levels at the PstSCAB transporter, which passes that signal to PhoR through an interaction with PhoU.

Gardner will also discuss his curent work exploring the link between Staphylococcus aureus antibiotic resistance and metabolism.

Dr. Bruce Brodersen named Veterinarian of the Year

Bruce Brodersen, veterinarian, associate professor and diagnostic pathologist at the University of Nebraska–Lincoln Veterinary Diagnostic Center in the School of Veterinary Medicine and Biomedical Sciences has been named veterinarian of the year by the Nebraska Veterinary Medical Association (NVMA). Brodersen received the award at the NVMA annual convention on Jan. 21 in Kearney.

“Being a part of the NVMA has been a very enriching experience for me and the relationships that I’ve developed over the years with other practitioners has been invaluable,” said Brodersen

The veterinarian of the year award is presented annually to an NVMA member whose contributions have advanced veterinary medicine in Nebraska, and whose service has benefited the association and community.

Brodersen has been an NVMA member since 2000. He has served on the board of directors, previously held the role of association president and currently serves on the legislative and public relations committees. He was instrumental in developing the NVMA website and spearheaded Nebraska’s first Oath in Action Day sponsored by the American Veterinary Medical Foundation.

Brodersen pioneered the use of immunohistochemistry on ear notches from cattle as a means to detect persistent bovine viral diarrhea (BVD) virus infection.

“This has had a profound benefit on the control of BVD disease for bovine practitioners everywhere,” said Vergil Heyer who presented Brodersen with the award.

Working in the Veterinary Diagnostic Center since 1992, Brodersen assists veterinarians, their clients and others responsible for animal and public health in the detection, prevention and understanding of disease. He also teaches second year veterinary students in systemic pathology and public health.


Congratulations Zachary Stromberg !

School of Veterinary Medicine and Biomedical Sciences graduate student Zachary Stromberg will receive a PhD in integrated biomedical sciences on December 18, 2015.

Zach completed his doctoral dissertation on “Detection Methods and Intestinal Adherence of Non-O157 Shiga Toxin-Producing Escherichia coli.” He focused on the prevalence and concentration of Shiga toxin-producing Escherichia coli in cattle. Additionally, he examined the interaction between Shiga toxin-producing Escherichia coli and intestinal epithelial cells.

Zach and his wife Loreen plan to continue their careers in research by obtaining post-doctoral positions.

We wish Zach all the best!


Gary Rupp Inducted into Cattle Production Veterinarian Hall of Fame

Dr. Gary Rupp, veterinarian, UNL emeritus professor and founding director of the Great Plains Veterinary Educational Center, was one of two veterinarians elected to the Cattle Production Veterinarian Hall of Fame at the American Association of Bovine Practitioners Annual Conference in September.

The Cattle Production Veterinary Hall of Fame honors the traditions of production veterinary medicine and the individuals who have made a lasting impact on the profession. Rupp and fellow inductee Dr. Jenks Britt were chosen by their peers from a group of six beef and dairy veterinarian nominees.

“The beef and dairy industries have been fortunate to benefit from the wisdom and advancements provided by these two remarkable veterinarians,” said Brent Meyer, D.V.M., beef cattle technical services, Merck Animal Health. “From the K-R Spay device designed by Dr. Rupp, to the Bov Eq Embryo Transfer Service developed by Dr. Britt, the innovations from these two men have significantly advanced beef and dairy cattle management and bovine reproduction.”

Rupp received his D.V.M. from Colorado State University in 1964. He spent two years teaching at the University of California-Davis, then moved to Meeker, Colorado to enter private practice. After eight years in practice, he left to pursue an opportunity to study ruminant nutrition and reproduction at Colorado State University in outpatient teaching. In 1983, Rupp accepted a position as associate professor at Texas A&M University in Beef Cattle Herd Health. In 1988 he came to Nebraska and was instrumental in the formation of the Great Plains Veterinary Educational Center (GPVEC). He served as GPVEC director for 22 years. Since retiring from the university in 2010, Rupp has operated a seedstock Angus operation in Oak, Nebraska.

With others, Rupp initiated the Cow-Calf Computerized Herd Health-Management Record System and was actively involved in the development of the Kimberling-Rupp Spay instrument. Along with the faculty at GPVEC, he also designed and implemented a variety of clinical teaching programs and began the Beef Cattle Production Management Series. Rupp has been a member of numerous state and national veterinary and beef cattle organizations.

“Receiving this honor is a deeply humbling experience, as I have not totally convinced myself that I measure up,” said Rupp. “I feel very fortunate to have spent most of my life working with and learning from livestock producers, veterinary practitioners, and others to make livestock production as good as it can be. I have always been impressed with the emotional connection those who work in the cattle industry have for the animals and environment.”

The Cattle Production Veterinary Hall of Fame is sponsored by Merck Animal Health, the American Association of Bovine Practitioners, the Academy of Veterinary Consultants, Bovine Veterinarian magazine and Osborn Barr.

Congratulations to Rakesh Basavalingappa and Govardhan Rathnaiah, recipients of the Widaman Distinguished Graduate Fellowship Award!

The fellowship is awarded to outstanding graduate students whose research is related to agriculture. Rakesh is a PhD student focusing on immunology in the lab of Dr. Jay Reddy, and Gov is a PhD student focusing on microbiology in the lab of Dr. Raul Barletta.

A luncheon to honor all those receiving graduate fellowships will be held at the Nebraska East Union on Tuesday, Oct. 13, 2015.

The Widaman Trust was established in 1975 through a generous gift provided to the University of Nebraska Foundation by Mrs. Blanch Widaman.
