Bio Item
Mohamed Seleem, DVM, MS, PhD , bioTyler J. and Frances F. Young Chair in Bacteriology; Professor
The Center for One Health Research (COHR) gathers faculty, staff, and students from VMCVM and the Edward Via College of Osteopathic Medicine (VCOM) who have a shared interest in cooperative research and scholarship related to infectious diseases. This collaboration is founded on the two schools’ One Health philosophy, which is based on the understanding that animal health, human health, and the environment are inextricably linked; consequently, professionals from these fields must work together to protect, promote, and improve overall health. The center coordinates research, instruction, and outreach activities related to understanding the disease processes that affect both animal and human health, and supports the continued advancement of the science and technology of disease-intervention strategies.
In 2020, significant renovations were completely to robustly grow VMCVM's research program in infectious diseases. The COHR's research laboratories were renovated to accommodate a large research team led by Dr. Mohamed Seleem, a newly recruited endowed chair in bacteriology. In addition, investments were made to improve the COHR's equipment, administrative infrastructure/operations, and animal facilities and support for ACE2 murine models for COVID researchers.
Faculty Labs

Redirect Item
Anandakrishnan Laboratory , redirectLed by principal investigator Ramu Anandakrishnan, assistant professor for biomedical sciences at Edward Via College of Osteopathic Medicine, the Anandakrishnan Lab is developing bioinformatics algorithms for identifying potential cancer genes and using CRISPR/Cas9 gene editing protocol to investigate the effect of mutations in the cancer genes identified above.
-
Redirect Item
Caswell Laboratory , redirectLed by principal investigator Clay Caswell, who has been studying bacterial pathogens for more than 15 years. His work has included characterizing mechanisms of Streptococcus and Brucella pathogenesis. Our group uses a combination of genetic and biochemical approaches, coupled with in vitro and in vivo model systems to identify and describe mechanisms that bacteria use to colonize and infect their hosts. Of particular interest are pathways that utilize transcriptional and posttranscriptional means to coordinate the expression of genes during infection.

Seleem Laboratory , redirect
Led by principal investigator Mohamed Seleem, professor and Tyler J. and Frances F. Young Chair in Bacteriology in the Department of Biomedical Sciences and Pathobiology, the Seleem Laboratory is focused on developing new antimicrobials and improving delivery of drugs for the treatment of infectious diseases. The lab is also developing novel methods for early detection and identification of a single bacterium and fungus in a complex environment.
-
Article Item
Smith Laboratory , articleLed by principal investigator Stephen Smith, the Aquatic Medicine Program and Laboratory serve as a resource and aquatic animal facility for faculty and graduate students. The program focuses on the diseases, diagnosis, pathology, immunology, parasitology and bacteriology of both vertebrate and invertebrate aquatic organisms. The Aquatic Medicine Laboratory is equipped to maintain a variety of freshwater and marine species and to provide a basic laboratory for investigations into these organisms. The lab also serves as a source of collaborative efforts with other institutions and agencies interested in the culture, diseases, and problems associated with aquatic organisms.

Article Item
Witonsky Laboratory , articleLed by principal investigator Sharon Witonsky, associate professor of equine field service in the Department of Large Animal Clinical Sciences, the Witonsky Lab's mission is unraveling the immunopathology of different pathogens and improving disease outcomes. Current efforts are focused predominantly on Equine Protozoal Myeloencephalitis (EPM).
Former COHR Directors
Nammalwar Sriranganathan, DVM, PhD
Email: nathans@vt.edu
Dr. Sriranganathan, former director of the Center for One Health Research (COHR). A member of the Virginia Tech community since 1984, Sriranganathan made significant contributions to research on vaccine development related to zoonotic diseases and gene regulation. He has written more than 200 publications and received four U.S. patents. The current USDA approved Brucellosis vaccine RB51 was developed at the COHR by Drs. Schurig, Boyle, and Sriranganathan and aided in the eradication of this disease in the United States. His more recent focus has been on host genetics and disease resistance and susceptibility in Brucellosis, Tuberculosis and Paratuberculosis. He hopes to help address zoonotic disease burden in the developing world.
Stephen M. Boyle, PhD
Email: smboyle@vt.edu
Stephen Boyle, professor emeritus of biomedical sciences and pathobiology and former director of Center for Molecular Medicine and Infectious Diseases (CMMID currently known as COHR) in the Virginia-Maryland Regional College of Veterinary Medicine at Virginia Tech. A member of the Virginia Tech community since 1984, Boyle made significant contributions to research on vaccine development related to zoonotic diseases and gene regulation. He has written more than 130 publications and received four U.S. patents. He was a founding member of the Alliance for Contraception for Cats and Dogs and served on its board and as chair of its Scientific Advisory Committee.
Gerhardt G. Schurig, DVM, PhD

Email: ansrahmd@vt.edu
Ansar Ahmed is a renowned researcher, former director of the Center for Molecular Medicine and Infectious Diseases, and former Associate Dean for Research with a primary focus on understanding the underlying mechanisms of autoimmune diseases. His laboratory investigates why the immune system targets self-tissues, leading to chronic autoimmune disorders such as lupus. To dissect the pathogenic autoimmune mechanisms, Dr. Ahmed employs various in vivo models, including wildtype, gene knockouts, and transgenic lupus murine models. His work is nationally and internationally recognized in this area. In addition to his research endeavors, Dr. Ahmed directs the DVM summer program, which offers research experience opportunities for Doctor of Veterinary Medicine students. Through his multifaceted contributions to research and education, Dr. Ahmed continues to make significant strides in advancing our understanding of autoimmune diseases and paving the way for innovative therapies.
