Objective Feasibility of using MNA cell-culture inoculation test to detect and isolate the street rabies virus. Methods Using MNA cell-culture inoculation test, fluorescent antibody test (FAT) and sandwich ELISA with double-antibodies to detect 33 specimens of street rabies virus, 20 specimens of negative canine brains and 4 specimens of healthy mice brains. Results 33 specimens of street rabies virus were positive to the cell-culture inoculation test but the others were negative. The concordances of MNA cell-cultured inoculation test with FAT and sandwich ELISA with double-antibodies were both 100%. Conclusion MNA cell-culture inoculation test appeared to be both highly sensitive and specific in detecting the street rabies virus, and could be used in detection and isolation of the virus.

A group of 25 rabies viruses (RABVs),recovered from 24 dogs and one human case,were collected from various areas in China between 2004 and 2006.Genetic and phylogenetic analyses of the G-L intergenic region were carried out in 25 street RABV isolates and CTN vaccine strains of 7 generations.The study was based on the comparison of a 519 bp nucleotide sequence,encompassing the G-L intergenic region.The nucleotide sequence homologies of Chinese street strains were from 95.5% to 100%.The phylogenetic analysis showed that all Chinese isolates clearly supported the placement of all Chinese viruses in Lyssavirus genotype 1 and they were distributed according to their geographical origins.All of the Chinese strains were closely related but they could still be divided into two groups:group of street strains and group of CTN strains.This study presents details about the molecular epidemiology of rabies viruses based on the sequences of the G-L Intergenic region.
