Human immunodeficiency virus (HIV)-infected patients with low CD4(+) T lymphocyte counts had a poor neutralizing antibody response to pre- and postexposure rabies vaccination. This study of HIV-infected patients with CD4(+) T lymphocyte counts < 200/microL indicated that patients had a poor response after 4-site intradermal vaccinations (4-4-4-0-2-2, doubling the intradermal doses of cell-cultu...

Rabbit anti-idiotypic antibodies (alpha Id Ab) were prepared against five murine monoclonal antibodies (mAb) specific for the rabies virus glycoprotein. Four of the mAb were directed against three known, type-specific, neutralizing sites on the glycoprotein, and the other mAb was directed against a topographically uncharacterized, nonneutralizing epitope. An absence of significant cross-reactiv...

PURPOSE To fight animal rabies, Moroccan veterinary authorities organize annual dog mass vaccination campaigns using Rabivac vaccine, an inactivated adjuvanted cell culture veterinary rabies vaccine. Two experiments were undertaken to assess the efficacy and immunogenicity of Rabivac. MATERIALS AND METHODS The first experiment involved 13 caged dogs (8 vaccinated and 5 negative controls). Dog...

Serum neutralization antibody and immunoglobulin responses in 30 individuals were studied in paired serum samples which had been obtained before and 2 to 3 weeks after the administration of a recall dose of rabies tissue culture vaccine. The immune reaction consisted of a predominantly immunoglobulin G (IgG) antibody response. Also, a significant increase in neutralizing antibody titers was obs...

In the present report an in vitro method for obtaining a secondary human antibody response to a dog kidney cell vaccine against rabies virus (DKCV) is described. Cultures of peripheral blood mononuclear cells from normal rabies-immune and nonimmune donors were stimulated in vitro by DKCV. The production of virus-specific antibody in supernatant fluids was monitored by ELISA. Antibody was produc...

Introduction: Grenada is a rabies endemic country, where terrestrial rabies is maintained in the small Indian mongoose (Herpestes auropunctatus). The role of bats in the epidemiology of rabies in Grenada is unknown. A 1974 report described one rabies virus positive Jamaican fruit bat (Artibeus jamaicensis), and a high seroprevalence in this species. In the current study, the natural exposure to...

during the epidemiological research of zoonoses, the authors have studied the rabies of wild animals : fox. for the scro lo-uical tests. the blood . was taken by heart puncture of foxes. 193 specimens were tested and 26 (13. 5%) o r the foxes had neut ralizing antibody in their blood. this study confirms that during the rabies epizooty. the vulpin population, may contract a non-fatal disease an...

Post-exposure prophylactic (PEP) neutralizing antibodies against Rabies are the most effective way to prevent infection-related fatality. The outer envelope glycoprotein of the Rabies virus (RABV) is the most significant surface antigen for generating virus-neutralizing antibodies. The small size and uncompromised functional specificity of single domain antibodies (sdAbs) can be exploited in th...

The need to replace rabies immune globulin (RIG) as an essential component of rabies postexposure prophylaxis is widely acknowledged. We set out to discover a unique combination of human monoclonal antibodies (MAbs) able to replace RIG. Stringent criteria concerning neutralizing potency, affinity, breadth of neutralization, and coverage of natural rabies virus (RV) isolates and in vitro escape ...

background: nanoparticles have been considered as promising tools because of their high applicability. recently, nanoparticles have been evaluated for their ability to increase the immune responses as adjuvants. silver-nanoparticles (agnps) have shown promising results in enhancing th-2 immune responses and to produce potent neutralizing antibodies. neutralizing antibodies are considered as the...
