Abstract |
We have developed a polymerase chain reaction for the detection of Norwalk virus using the published sequence of the virus RNA dependent RNA polymerase gene and have used this to clone and sequence this region of a virus from a UK outbreak. We have applied this method to a panel of UK Norwalk-like viruses using both Tet-z and Taq DNA polymerases and found that amplification produces a multiplicity of bands from stool samples. However, in combination with Southern blotting, Taq polymerase amplification detected virus in 13 of a panel of 30 clinical samples known to contain these viruses and also detected astroviruses in a mixed infection. Amplification using Tet- z DNA polymerase was less efficient (6/30) and detected predominantly viruses typed as UK type 2 by solid phase immune electron microscopy.
