One of the methods used for controlling cattle rabies in Brazil consists of vaccination. Sometimes, however, rabies occurs in cattle supposedly protected. Since rabies vaccine batches are officially controlled by tests performed on laboratory animals, it is questionable whether the minimal mandatory requirements really correspond to immunogenicity in the target species. We have analyzed the ass...

A new approach to the production and delivery of vaccine antigens is the use of engineered amino virus-based vectors. A chimeric peptide containing antigenic determinants from rabies virus glycoprotein (G protein) (amino acids 253-275) and nucleoprotein (N protein) (amino acids 404-418) was PCR-amplified and cloned as a translational fusion product with the alfalfa mosaic virus (AlMV) coat prot...

OBJECTIVE To determine effect of route of challenge and strain of rabies virus on efficacy of inactivated rabies vaccines in mice. ANIMALS 3,056 mice. PROCEDURE Challenge was performed with fixed and street rabies virus strains by use of footpad and intracerebral routes as well as IM injection into the hip, shoulder, neck, and masseter muscles. Intraperitoneal and IM vaccination was perform...

OBJECTIVE To evaluate the effectiveness of intervention efforts to halt 2 wildlife rabies epizootics from 1995 through 2003, including 9 oral rabies vaccination campaigns for coyotes and 8 oral rabies vaccination campaigns for gray foxes. DESIGN Retrospective study. ANIMALS 98 coyotes during prevaccination surveillance and 963 coyotes and 104 nontarget animals during postvaccination surveil...

Rabies is a virtually 100% fatal acute viral encephalitis. Rabies occurs in more than 150 countries and territories. Globally there are 17.4 million animal bite cases and more than 55,000 deaths annually. India's 20,000 deaths accounts for 36% of global and 65% of the Asian (31,000) deaths. The Intradermal Rabies Vaccine (IDRV) was first started in Thailand in 1984. In 1992, World Health Organi...

Rabies is a fatal zoonotic disease for which no effective treatment measures are currently available. Rabies virus (RABV) has anti-apoptotic and anti-inflammatory properties that suppress nerve cell damage and inflammation in the CNS. These features imply that the elimination of RABV from the CNS by appropriate treatment could lead to complete recovery from rabies. Ten rabbits showing neuromusc...

The aim of the study was monitoring the efficacy of primary vaccination against rabies and the need for booster doses. These studies validate at the same time recent technological improvements in laboratory diagnostics of the level of rabies protection in human sera. Research was carried out into the level of antibodies, considering that an antibody titer ≥0.5 IU/mL is protective. We used Plate...

Objectives. Rabies is a fatal acute viral zoonotic disease causing encephalomyelitis in humans and many other mammalian animals. Prophylaxis is vital since there is no treatment for rabies. This study was a comparison of antibody levels in patients who were vaccinated following different vaccinationprotocols. Methods. Eightyfive patients who were included in the rabies vaccination program who p...

Animal rabies control has been frustrated by the existence of multiple wildlife reservoirs and the lack of efficacious oral vaccines. In this investigation, raccoons fed a vaccinia-rabies glycoprotein recombinant virus in a sponge bait developed rabies virus-neutralizing antibody (0.6-54.0 units) and resisted street rabies virus infection 28 and 205 days after feeding. Additional raccoons immun...

Rabies is a zoonotic disease that affects all mammals and leads to more than 55,000 human deaths every year, caused by rabies virus (RABV) (Mononegavirales: Rhabdoviridae: Lyssavirus). Currently, human rabies treatment is based on the Milwaukee Protocol which consists on the induction of coma and massive antiviral therapy. The aim of this study was to assess the decrease in the titer of rabies ...
