A dot hybridisation assay for detection of rotavirus.

A "dot" hybridisation technique for the detection of rotavirus in stools and other biological materials is described. The assay is based on the in-situ hybridisation of labelled single-stranded RNA probes, obtained by in-vitro transcription of rotavirus particles, to heat-denatured rotavirus RNA immobilised on nitrocellulose membranes. The method is highly specific and allows for the detection of as little as 8 pg of viral RNA. Its use for the detection of rotavirus in stool suspensions and rectal swabs obtained from children with diarrhoea may facilitate epidemiological studies of rotavirus gastroenteritis.
