A candidate for a new serotype of human rotavirus

Abstract

We investigated genetic and serological characteristics of a human rotavirus isolate from Indonesia which had a "super short" RNA electrophoretic pattern (A. Hasegawa, S. Inouye, S. Matsuno, K. Yamaoka, R. Eko, and W. Suharyono, Microbiol. Immunol. 28:719-722, 1984). This virus, strain 69M, was found by RNA-RNA hybridization to have a low degree of homology with the representative strains of all four human serotypes. Furthermore, it could not be classified by neutralization analysis into any of these serotypes. Therefore, this virus might belong to a new serotype.
