Studies on Immunity in Anthrax

Stability and potency studies of anthrax vaccine (Bacillus anthracis 34F2 Sterne strain) in Iran

  For evaluation the stability and potency of anthrax vaccine prepared in Razi Vaccine and Serum Research Institute in Iran, samples of different batches of vaccine were kept at 4-8 °C (refrigerator), 20-25 °C (room temperature) and 37 °C (incubator).The viable spores/ml of vaccines were determined using plate–counting method before and after holding at different temperatures monthly. Vaccine p...

The immunity conferred by anthrax avirulent uncapsulated live vaccine following different methods (intradermal and subcutaneous) of vaccination

Frequent and seasonally variable sublethal anthrax infections are accompanied by short-lived immunity in an endemic system.

Few studies have examined host-pathogen interactions in wildlife from an immunological perspective, particularly in the context of seasonal and longitudinal dynamics. In addition, though most ecological immunology studies employ serological antibody assays, endpoint titre determination is usually based on subjective criteria and needs to be made more objective. Despite the fact that anthrax is ...

Raxibacumab: potential role in the treatment of inhalational anthrax

Anthrax is a highly contagious and potentially fatal human disease caused by Bacillus anthracis, an aerobic, Gram-positive, spore-forming rod-shaped bacterium with worldwide distribution as a zoonotic infection in herbivore animals. Bioterrorist attacks with inhalational anthrax have prompted the development of more effective treatments. Antibodies against anthrax toxin have been shown to decre...

Identification of a protein subset of the anthrax spore immunome in humans immunized with the anthrax vaccine adsorbed preparation.

We identified spore targets of Anthrax Vaccine Adsorbed (AVA)-induced immunity in humans by screening recombinant clones of a previously generated, limited genomic Bacillus anthracis Sterne (pXO1(+), pXO2(-)) expression library of putative spore surface (spore-associated [SA]) proteins with pooled sera from human adults immunized with AVA (immune sera), the anthrax vaccine currently approved fo...

Role of anthrax toxins in dissemination, disease progression, and induction of protective adaptive immunity in the mouse aerosol challenge model.

Anthrax toxins significantly contribute to anthrax disease pathogenesis, and mechanisms by which the toxins affect host cellular responses have been identified with purified toxins. However, the contribution of anthrax toxin proteins to dissemination, disease progression, and subsequent immunity after aerosol infection with spores has not been clearly elucidated. To better understand the role o...
