Serotypic characterization of outer capsid spike protein VP4 of vervet monkey rotavirus SA11 strain

Serotypic characterization of outer capsid spike protein VP4 of vervet monkey rotavirus SA11 strain The vervet monkey rotavirus SA11, a prototype strain of group A rotaviruses, has been shown to possess VP7 serotype 3 specificity but its neutralization specificity with regard to the other outer capsid protein VP4 has not been elucidated. We thus determined its VP4 specificity by two-way cross-neutralization with guinea pig antiserum prepared with a single gene substitution reassortant that had only the VP4-encoding gene from the simian rotavirus SA11 strain and remaining ten genes from human rotavirus DS-1 strain (G serotype 2). The SA11 VP4 was related antigenically in a one-way fashion to rhesus monkey rotavirus MMU18006 VP4 (a P5B strain) and marginally to human and canine rotavirus VP4s with P serotype 5A specificity. In addition, the SA11 VP4 was shown to be distinct antigenically from those of other known P serotypes (1–4, and 6–11) as well as those of uncharacterized equine, lapine, and avian rotavirus strains. The SA11 VP4 is thus proposed for classification as a P5B serotype. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Archives of Virology Springer Journals

Abstract

The vervet monkey rotavirus SA11, a prototype strain of group A rotaviruses, has been shown to possess VP7 serotype 3 specificity but its neutralization specificity with regard to the other outer capsid protein VP4 has not been elucidated. We thus determined its VP4 specificity by two-way cross-neutralization with guinea pig antiserum prepared with a single gene substitution reassortant that had only the VP4-encoding gene from the simian rotavirus SA11 strain and remaining ten genes from human rotavirus DS-1 strain (G serotype 2). The SA11 VP4 was related antigenically in a one-way fashion to rhesus monkey rotavirus MMU18006 VP4 (a P5B strain) and marginally to human and canine rotavirus VP4s with P serotype 5A specificity. In addition, the SA11 VP4 was shown to be distinct antigenically from those of other known P serotypes (1–4, and 6–11) as well as those of uncharacterized equine, lapine, and avian rotavirus strains. The SA11 VP4 is thus proposed for classification as a P5B serotype.
