In this study, the immunogenicity of a rabies vaccine that was used in one of the Isfahan cattle farms is reported. This vaccine was produced by replication of the Pasteur virus (PV) strain on BHK-21 monolayer cell culture. The virus suspension was inactivated by ß-propiolactone treatment and the harvested pool showed sterility and safety. Thus, the obtained vaccine was tested on mice and a sat...

The replication of seven rabies virus strains (CVS, HEP, PV, ERA, WIRAB, CPZ and BOLIVAR) in BHK cells and the inactivation dynamics of these strains by beta-propiolactone, acetylethylenimine, and ethylenimine were studied to find the most immunogenic strain and the most economic and stable inactivating agent for the production of an inactivated tissue culture rabies vaccine for animal use. The...

A tissue culture system for detecting rabies virus from saliva samples of suspected animals was developed and compared to suckling mouse inoculation. Swab samples were obtained from the mouth of the animal heads received for rabies diagnosis; these swabs were submerged in maintenance medium. The maintenance medium was inoculated intracerebrally into suckling mice and onto BHK-21 cells with diet...

PURPOSE Delayed onset of, and low magnitude of, protective immune responses are major drawbacks limiting the practical utility of plasmid vaccination against rabies. In this study we evaluated whether nanoformulation with the novel poly(ether imine) (PETIM) dendrimer can enhance the immunogenicity and efficacy of a plasmid-based rabies vaccine. MATERIALS AND METHODS A plasmid vaccine construc...

The sensitivities of BHK-21 (C-13) and murine neuroblastoma (C-1300; clone NA) cells for the isolation of small quantities of a street strain rabies virus were compared. Suspensions of brain from mice sacrificed prior to the onset of clinical signs of rabies were used to stimulate weakly positive diagnostic specimens. The results of cell culture isolation were compared with those of the direct ...

the main aim of this study was to find a suitable rabies vaccination protocol which would allow usage of lower volumes of vaccine, fewer clinical visits and above all, enough serological effectiveness for high-risk individuals requiring pre-exposure immunization. human diploid cell rabies vaccine was administered intradermally and intramuscularly in 60 previously unvaccinated volunteers, aged 1...

This study aimed to test in vitro a RNA-interference based antiviral approach for rabies with short-interfering RNAs (siRNAs) against rabies virus nucleoprotein mRNA. BHK-21 cells were infected with serial dilutions of PV rabies virus strain and transfected with a pool of three siRNAs. Direct immunofluorescence staining showed a 5-time decrease in virus titer when compared to a non-treated plat...

The inactivation dynamics of rabies virus (PV strain) by binary ethylenimine, and the immunogenic properites and the stability of the vaccines prepared using this agent, were studied. Binary ethylenimine at a final concentration of 0.01 M was prepared wtih 2-bromoethylamine hydrobromide in alkaline solutions, either separately from or in suspensions of rabies virus propagated in BHK cells. The ...

Rabies remains an important worldwide health problem. Newcastle disease virus (NDV) was developed as a vaccine vector in animals by using a reverse genetics approach. Previously, our group generated a recombinant NDV (LaSota strain) expressing the complete rabies virus G protein (RVG), named rL-RVG. In this study, we constructed the variant rL-RVGTM, which expresses a chimeric rabies virus G pr...
