Research Funding

NIFA, USDA. Molecular attenuation mechanisms of porcine epidemic diarrhea virus in pigs.

PI: Wang, Q, Co-PI: Saif, LJ; Co-Is: Baric, R, Sims A, and Jung, K

Goal: To exploit different strategies to generate PEDV strains with reduced virulence, to identify genomic hot spots related to attenuation, and finally to verify those hot spots using infectious clone platform.  Our final goal is to generate and identify PEDV vaccine candidates, and obtain knowledge to advance the development of a safe attenuated PEDV vaccine to prevent further deadly PEDV outbreaks in the US, and to aid in innovative vaccine design against other fatal animal and human coronavirus diseases, such as Severe Acute Respiratory Syndrome (SARS) and Middle East respiratory syndrome (MERS).


NIFA, USDA. Human noroviruses: Mechanisms of attachment and internalization in leafy greens. PI: Wang, Q; Co-Is: Saif, LJ, Esseili, MA, Ivey, M, Meulia,T

Goal: To identify the capsid amino acids important in norovirus binding to lettuce leaves, to identify the lettuce cell wall carbohydrate(s) involved in norovirus binding and plant-derived lectin inhibitors for binding, to investigate whether specific binding of norovirus to lettuce carbohydrates enhances virus persistence and entry into the leaf, and  to elucidate mechanisms of norovirus (and infectious sapovirus) entry through the roots, their interaction with components of the vascular system, and their internal transport inside the lettuce plant. Our final goal is to improve public health by decreasing gastroenteritis outbreaks/cases due to leafy green contamination of human enteric noroviruses and sapoviruses.
