Development of a Novel Anthrax Vaccine Comprising LF-PA Chimera

Development of an improved vaccine for anthrax.

Bacillus anthracis are aerobic or facultatively anaerobic Gram-positive, nonmotile rods measuring 1.0 μm wide by 3.0–5.0 μm long. Under adverse conditions, B. anthracis form highly resistant endospores (Figure 1). These are found in soil at sites where infected animals previously died. Interest in the pathogenesis, immunity, and vaccine development for anthrax was heightened by the deliberate c...

A Novel Chimeric Anti-PA Neutralizing Antibody for Postexposure Prophylaxis and Treatment of Anthrax

Anthrax is a highly lethal infectious disease caused by the bacterium Bacillus anthracis, and the associated shock is closely related to the lethal toxin (LeTx) produced by the bacterium. The central role played by the 63 kDa protective antigen (PA63) region of LeTx in the pathophysiology of anthrax makes it an excellent therapeutic target. In the present study, a human/murine chimeric IgG mAb,...

Novel Delivery Systems for Nasal Administration of Anthrax Vaccine

Sheena Hailin Wang: Novel Delivery Systems for Nasal Administration of Anthrax Vaccine (Under the direction of Dr. Anthony J. Hickey, Ph.D., D.Sc.) There is current biodefense interest in protection against Anthrax. The inhaled form of anthrax is difficult to diagnose and can be fatal without prompt antibiotic intervention. Prophylactic vaccination has become a critical measure for protection o...

A new Approach to active Immunization of Sheep by a combined Sheep pox and Anthrax Vaccine

Neutralizing Antibody Response and Efficacy of Novel Recombinant Tetravalent Dengue DNA Vaccine Comprising Envelope Domain III in Mice

Background: Dengue is a global arboviral threat to humans; causing 390 million infections per year. The availability of safe and effective tetravalent dengue vaccine is a global requirement to prevent epidemics, morbidity, and mortality associated with it. Methods: Five experimental groups (6 mice per group) each of 5-week-old BALB/c mice were immunized with vaccine and placebo (empty plasmid) ...
