Detection and identification of rabies and rabies-related viruses using rapid-cycle PCR

The rapid identification of suspect rabies infection is essential in human cases, to ensure appropriate post-exposure treatment of contacts, and in animal cases to allow specific control strategies to be decided and implemented. We describe here the use of high speed air thermo-cycler PCR as a diagnostic tool for the detection of rabies and rabies-related viruses. Using this technique we were able to diagnose rabies in a human within 5 h. Furthermore, the application of automated sequencing of the resultant product enabled a definitive characterisation of classical rabies within 16 h. The utility of this assay was confirmed further by the successful detection of representatives of the six lyssavirus genotypes. Crown copyright (C) 1999 Elsevier Science B.V. All rights reserved.
