Implication

Diagnostic study demonstrates direct serotyping of human rotavirus using segment 9 cDNA probes in clinical isolates, indicating annual shifts in single dominant circulating strains.

Key Points

To evaluate whether cDNA probes derived from segment 9 of the rotavirus genome can directly differentiate human rotavirus serotypes in clinical specimens and to profile circulating strains in a community over time.
Applied stringent nucleic acid hybridization using serotype-specific cDNA probes derived from gene segment 9 (encoding VP7) to culture-grown viruses and uncultured clinical isolates.
Cross-referenced hybridization findings with genomic RNA electrophoretic mobility patterns (short versus long) and patient serum neutralizing antibody responses.
Profiled the temporal distribution of rotavirus serotypes collected from patients in Guangzhou and Foshan across three consecutive years (1982–1985).
Segment 9 cDNA probes hybridized specifically to homologous serotypes, reliably matching serotype 2 with short RNA electrophoretic patterns and serotypes 1, 3, or 4 with long electrophoretic patterns.
Hybridization-identified serotypes matched the predominant neutralizing antibody response observed in patient serum samples.
All isolates belonged to serotypes 1 through 4, with a single serotype dominating the community each year and minimal cocirculation before shifting in subsequent years.
