Jeff Withey, Ph.D., assistant professor of immunology and microbiology in WSU's School of Medicine, recently received two grants from the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, to use zebrafish to study the spread of cholera and characterize signals that induce the disease in humans.
