Molecular epidemiology of rabies virus in France: comparison with vaccine strains.

EPIDEMIOLOGICAL SURVEY OF DIFFERENT RABIES VIRUS STRAINS IN IRAN

Rabies is widespread in all provinces of Iran. This study presents an investigation by a Polymerase Chain Reaction (PCR) technique for the purpose of rabies diagnosis and also Restriction Fragment Length Polymorphism (RFLP) for determination of the type of the rabies virus. In addition, PCR proves to be a powerful tool for molecular epidemiology studies allowing analysis of the infecting strain...

Antigenic variation between rabies virus strains and its relevance in vaccine production and potency testing

Sequence and Phylogenetic Analysis of Wild Type Rubella virus isolated in Iran

Background and Aims: Rubella virus is a human pathogen that causes congenital rubella syndrome (CRS) when infection occurs during early pregnancy. Vaccination programs have been remarkably successful in controlling natural rubella infection and CRS. Moreover, ongoing surveillance for all cases of rubella and CRS is a vital component of a prevention program. Although the WHO recommends the use o...

Molecular Comparison of Three Different Regions of the Genome of Infectious Bronchitis Virus Field Isolates and Vaccine Strains

Rapid detection and differentiation of infectious bronchitis virus (IBV) involved in the disease outbreak is very important for controlling disease and developing new vaccines. In the present study, three regions of the genome of IBV vaccine and field isolates including S1 gene, gene 3 and nucleocapsid (N) gene along with 3' untranslated region (3' UTR) were amplified and subjected to restricti...

Comparison of Immune Responses following Intradermal and Intramuscular Rabies Vaccination Methods

Rabies is a zoonotic viral disease. The causative agent is a negative-sense RNA genome virus of the genus Lyssavirus (Family: Rhabdoviridae). The disease, commonly transmitted by rabid dogs, is the cause of mortality of over 59000 humans worldwide annually. This disease can be prevented before the development of symptoms through proper vaccination even after exposure. Hence, improvement of the ...
