Norovirus TEM proposal, Straub


EMSL Project ID
16297

Abstract

Human noroviruses are thought to be the leading cause of non-bacterial gastroenteritis throughout the world. Recent data suggests that the viruse is undergoing mutation leading to increased virulence and causing death in some victims. Efforts to study this virus have been hampered by a lack of a suitable in vitro cell culture system. Our goal is to develop an in vitro cell cultivation system using low-shear microgravity culture systems. Successful cultivation will be measured in several different ways including gross histopathological examination of cell cultures, fluorescent in-situ hybridization, real-time PCR, and electron microscopy. For the purposes of this proposal, we would be seeking access for the electron microscopy facilities at EMSL. Collaborations with EMSL to date suggests that our work in cultivating these viruses has been successful. External peer reviewers have suggested that this work be submitted to Nature because of the unique methods and significant discoveries.
