Abstract: Double-stranded cDNA was synthesized from nucleic acid extracted from Norwalk virus purified from stool specimens of volunteers. One clone was isolated from a cDNA library constructed in a pUC-13 vector after amplification of the cDNA. The specificity of this cDNA (pUCNV-953) was shown by hybridization assays. The cDNA reacted with post (but not pre-) infection stool samples from Norwalk volunteers and with highly purified Norwalk virus, but not with other common enteric viruses such as hepatitis A virus and rotavirus. Finally, the probe detected virus in the same fractions of CsCl gradients in which viral antigen was detected using a specific Norwalk virus radioimmunoassay, and particles were detected by immune electron microscopy. Single-stranded RNA probes derived from the DNA clone after subcloning into an in vitro transcription vector were also used to show that the Norwalk virus contains a ssRNA genome of about 8 kb in size.

Abstract: The invention relates to an improved rotavirus vaccine for man and animals and methods of using them. The invention comprises a method of immunizing humans, particularly children, and animals against rotavirus infections by parenteral immunization. The immunization may be carried out in a series of injections using live or inactivated vaccines, alone or in combination with each other or in combination with a rotavirus subunit vaccine or oral vaccine.

Abstract: The rotavirus nonstructural glycoprotein, NSP4, performs multiple functions in the virus replication cycle, especially during viral morphogenesis. Specifically, NSP4 is an intracellular receptor that mediates the acquisition of a transient membrane envelope during the budding of newly formed subviral particles into the endoplasmic reticulum (ER). The present invention relates to NSP4 and methods of use. More particulary, it relates to the use of NSP4 and fragments thereof (NSP4 114-135, NSP4 120-147, NSP4 112-174, or NSP4 112-150) as a prevention and/or treatment of rotaviral disease.
