In the past 5 years, we have conduc...

We report the first complete sequence for an avian group G rotavirus (RVG) genome from Africa, which is the third publically available RVG genome. These RVG genomes are highly diverse, especially in their VP4, VP7, NSP4, and NSP3 segments, indicating that RVG diversity is comparable to that of rotavirus A.

We detected rotavirus G5P[6] with a long RNA pattern in a Vietnamese child with diarrhea. Viral outer capsid protein VP7 and VP4 genes suggest that it likely originated from porcine rotavirus either by genetic reassortment or as whole virions. To our knowledge, this is the first report of human rotavirus G5 in Asia.

Eubenangee virus has previously been identified as the cause of Tammar sudden death syndrome (TSDS). Eubenangee virus (EUBV), Tilligery virus (TILV), Pata virus (PATAV) and Ngoupe virus (NGOV) are currently all classified within the Eubenangee virus species of the genus Orbivirus, family Reoviridae. Full genome sequencing confirmed that EUBV and TILV (both of which are from Australia) show high...

We recently described an assay that measures fusion from without induced in tissue culture cells by rotavirus, a nonenveloped, triple-protein-layered member of the Reoviridae family (M. M. Falconer, J. M. Gilbert, A. M. Roper, H. B. Greenberg, and J. S. Gavora, J. Virol. 69:5582-5591, 1995). The conditions required for syncytium formation are similar to those for viral penetration of the plasma...

Maturation of rotavirus occurs in the ER. The virus transiently acquires an ER-derived membrane surrounding the virus particle before the eventual formation of double-shelled particles. The maturation process includes the retention and selective loss of specific viral protein(s) as well as the ER-derived membrane during formation of the outer capsid of the mature virus. When infected cells were...

Rotavirus RNA was detected in the cerebrospinal fluid (CSF) of a child with central nervous system disease symptoms associated with rotavirus gastroenteritis. The rotavirus isolates from the fecal and CSF samples were genotyped as G1P[8]. Sequence analysis of the VP7 and VP4 proteins derived from the fecal and CSF samples were remarkably similar to each other and to G1P[8] rotavirus strains com...
