Synthetic oligonucleotide primers to glycoprotein gene of rabies virus and based by nested polymerase chain reaction method for RNA Rabies virus detection

Abstract

One of widely used methods to detect rabies virus RNA is a reverse transcription chain polymerase reaction (RT-PCR) allowing to determine a diagnosis in 5 hours. Thus, we have elaborated the method that allows to pursue effective elicitation of RNA strains and isolates of rabies virus in pathological and clinical material as well as to decrease research timespan to 6 hours, to lower by 9.8 times the diagnostics prime cost, labor expenditures – by 40 times. The way includes performance of nested RT-PCR with oligonucleotide primers having definite nucleotide sequences and synthesized to conservative glycoprotein gene. Wherein RT-PCR is pursued in two rounds. In the case of positive reaction, fragment corresponding to the size in the first round – 755 bp, in the second round – 259 bp, is synthesized.

“…Rabies virus penetrates from the place of initial localization into neuron axon via unmyelinated terminal and begins then motion towards CNS with the use of retrograde mechanisms of axoplasmic transport [14,15]. Virus particle moving speed across peripheral nervous CNS tissues can alternate but as a rule it is rather small and is from 12 to 24 mm per day [16].…”
