Persistence Of Enteric Viruses On Surfaces Under Varying Environmental Conditions, Nicole L. Turnage

Graduate Theses and Dissertations

Human enteric viruses such as human norovirus (hNoV) and Aichivirus A (AiV) are common foodborne viruses with hNoVs being identified as the leading causative agent of foodborne illnesses in the U.S. Moreover, hNoVs have been identified as the leading cause of nonbacterial acute gastroenteritis in the U.S. and worldwide. Fomite surface contamination is a major transmission route for enteric viruses. The application of an optimized virus recovery method from fomites is essential for better understanding of virus persistence under varying environmental conditions (EC). This study aimed to optimize a surface sampling method for virus recovery from nonporous food contact surfaces …

Biochemical, Structural, And Drug Design Studies Of Norovirus And Zika Virus Proteases, Ben Kuiper

Wayne State University Dissertations

Noroviruses, which are the leading cause of acute gastroenteritis, cause an estimated 677 million infections and 213,000 deaths each year worldwide. Noroviruses are classified into seven genogroups (GI-GVII); GI, GII, and GIV have been shown to be infectious in humans. However, GII noroviruses cause the majority of outbreaks (89%). No pharmacologic treatment or vaccine currently exists to treat or prevent norovirus infections.

Recently, the development of a norovirus replicon system, a murine model of norovirus infection, and the development of a biochemical protease assay have allowed for the design and development of norovirus inhibitors. However, the replicon and biochemical assay …
