Although effective rabies virus vaccines have been existing for decades, each year, rabies virus infections still cause around 50.000 fatalities worldwide. Most of these cases occur in developing countries, where these vaccines are not available. The reasons for this are the prohibitive high costs of cell culture or egg grown rabies virus vaccines and the lack of a functional cold chain in many...
A novel double-antigen sandwich enzyme-linked immunosorbent assay (ELISA) was developed to measure rabies antibodies in dogs. In contrast to the 4 days required for detecting rabies antibody with conventional rabies antibody virus neutralization assays, this ELISA can be completed in hours, without using live virus, in routine laboratories.
IMPORTANCE The rabies virus causes a fatal encephalitis and can be transmitted through tissue or organ transplantation. In February 2013, a kidney recipient with no reported exposures to potentially rabid animals died from rabies 18 months after transplantation. OBJECTIVES To investigate whether organ transplantation was the source of rabies virus exposure in the kidney recipient, and to eval...
Although current postexposure prophylaxis rabies virus (RV) vaccines are effective, approximately 40,000-70,000 rabies-related deaths are reported annually worldwide. The development of effective formulations requiring only 1-2 applications would significantly reduce mortality. We assessed in mice and nonhuman primates the efficacy of replication-deficient RV vaccine vectors that lack either th...
Rabies is a fatal zoonotic disease of serious public health and economic significance worldwide. The rabies virus glycoprotein (RVG) has been the major target for subunit vaccine development, since it harbors domains responsible for induction of virus-neutralizing antibodies, infectivity, and neurovirulence. The glycoprotein (G) was cloned using the baculovirus expression vector system (BEVS) a...
PURPOSE A new rabies vaccine for animals, including raccoon dogs, in Korea is needed to eradicate rabies infection. In this study, we constructed two recombinant adenoviruses expressing the glycoprotein or nucleoprotein of the rabies virus (RABV). We then investigated the safety and immunogenicity of these strains in raccoon dogs, depending on inoculation route. MATERIALS AND METHODS Recombin...
B cells secreting IgG antibodies, but not IgM, are thought to be solely responsible for vaccine-induced protection against rabies virus (RABV) infections in postexposure settings. In this report, we reinvestigated the potential for IgM to mediate protection in a mouse model of RABV vaccination. Immunocompetent mice immunized with an experimental live replication-deficient RABV-based vaccine pro...
Humoral immune response using inactivated rabies vaccine was studied in 35 nelore cross-bred bovines of western region of São Paulo state. Ninety days after vaccination, 13 (92.8%) animals presented titers > or = 0.5 IU/ml, through mouse neutralization test. After 180 days, 9 (64.3%) sera showed titers > or = 0.5 IU/ml, after 270 days, only one (7.1%) showed a titer of 0.51 IU/ml, and after 360...
PURPOSE Rabies viruses (RABV) circulating worldwide in various carnivores occasionally cause fatal encephalitis in swine. In this study, the safety and immunogenicity of a recombinant rabies virus, the ERAGS strain constructed with a reverse genetics system, was evaluated in domestic pigs. MATERIALS AND METHODS Growing pigs were administered 1 mL (10(8.0) FAID50/mL) of the ERAGS strain via in...
A rapid and sensitive enzyme immunoassay is described for detecting rabies antibody in hybridoma culture fluids. Glass fiber filter disks were used to immobilize gamma-irradiated mouse neuroblastoma cells infected with street or laboratory strains of rabies virus. Bound rabies-specific antibody was detected by reaction with horseradish peroxidase-labeled goat anti-mouse immunoglobulin G. The as...
