چکیده

Rabies is a fatal acute viral zoonosis, causing 62,000 human deaths every year. The oral rabies vaccination (ORV) programs of foxes, the main reservoir of rabies in Europe, are the most effective tools to control and finally to eradicate the disease. In order to characterize by in vivo and in vitro assays a vaccine rabies strain isolated from a rabid cattle following the ORV program, it has been used BHK21, N2a cell line and mice inoculation test. The results showed that the vaccine strain is able to grow on BHK21 cells, like an attenuated live vaccine, as well as on N2a cell line, usually used for diagnosis, while wild rabies strains from naturally infection were isolated on N2a cells only. The intra-cerebrally inoculated mice with vaccine strain developed disease signs and died in 12 days, one day later than inoculated mice with a local strain virus from natural infection.

In-vitro and In-vivo Evaluation of Silymarin Nanoliposomes against Isolated Methicillin-resistant Staphylococcus aureus

Staphylococcus aureus is an opportunistic pathogen and remains a common cause of burn wound infections. Different studies have shown that entrapment of plant-derived compounds into liposomes could increase their anti-Staphylococcus aureus activity. Silymarin is the bioactive extract from the known plant Silybum marianum L. The objective of this study was to evaluate efficacy of silymarin in fre...

Immunogenicity of BHK-Rabies Vaccine in Cattle

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...
