Dr. Chowdhury’s long-term goal is to understand the following two specific areas of BHV-1 research: How BHV-1 and BHV-5 spread within the nervous system. . The role of envelope glycoproteins in the regulation of pathogenicity and immunogenicity of BHV-1. Both projects are funded by the U.S. Department of Agriculture. The researchers investigating respiratory diseases in humans are: Samithamby Jeyaseelan, DVM, Ph.D., an assistant professor in the Department of Pathobiological Sciences. . Maria Antonieta Guerrero-Plata, BSc, MSc, Ph.D., also an assistant professor in the department. . Arthur Penn, Ph.D., a professor of toxicology in the Department of Comparative Biomedical Sciences and director of the Inhalation Research Facility. <HOME>
