Verification of the rabies virus glycoprotein lower limit of immunogenicity by serological assay.

Rabies lethality is close to 100% and annually 15 million people receive post-exposure prophylaxis. Testing for vaccines against this zoonosis should ensure its quality. A standardized test by the National Institutes of Health (NIH) test, based on mice immunization and challenge, has been used to determine the potency of vaccine lots.

Development and pre-validation of a quantitative multi-dose serological assay for potency testing of inactivated rabies vaccines for human use.

It is mandatory to ensure the quality of biological products used in the prevention of rabies, a zoonosis with nearly 100% lethality. Fifteen million people receive post-exposure prophylaxis yearly. The vaccine batches are assessed by the National Institutes of Health (NIH) test which has several disadvantages such as significant variability and animal welfare issues.

Circulation of the rabies virus in non-hematophagous bats in the city of Rio de Janeiro, Brazil, during 2001-2010.

Introduction: Rabies is one of the most known lethal zoonosis, responsible for 55,000 human deaths per year. It is transmitted to humans mainly by the bite of domestic or wild animals infected with the virus. This paper shows the circulation of this virus in non-hematophagous bats in the City of Rio de Janeiro, Brazil.

[Rabies virus in Nyctinomops laticaudatus bats in the City of Rio de Janeiro: isolation, titration and epidemiology].

The first case report of rabies in bats of the species Nyctinomops laticaudatus, in the city of Rio de Janeiro City, is presented. Virus isolation and titration were performed in different tissues, and high titers were found in the brain and salivary glands. Rabies occurrence in such an infrequent species in this state suggests that the disease may be more prevalent than it appears to be.
