  • Publication number: 20240148800
    Abstract: Compositions and methods for treating or reducing the severity of occurrence of a parasitic worm or helminth infection in a subject are described. The methods include administering to the subject a therapeutically effective amount of a composition comprising isolated native, bioactive nematicidal crystals formed from a single type of nematicidal crystal protein. The isolated native, bioactive nematicidal crystals are substantially free of any bacterial spores or host bacterial proteins, other than nematicidal crystal protein in the form of a crystal. Methods for making isolated native, bioactive nematicidal crystals are also described. The crystal proteins may be full length, truncated, variant, or sub-variant Cry proteins. Examples of crystal proteins include Cry5B, Cry21, Cry14A, Cry6A, and Cry13A.

  • Patent number: 8865679
    Abstract: The present invention provides a means to broadly protect the military and the public from injury from biological warfare weapons, particularly infective agents such as anthrax. Beta (1,3)-glucans, particularly whole glucan particles, PGG-Glucan, and microparticulate glucan, provide general immune enhancement, thereby increasing the body's ability to defend against a wide variety of biological threats. Beta (1,3)-glucans have been shown to increase the resistance to infection by anthrax and other infectious organisms when administered before and after infection. The anti-infective mechanism of ?(1,3)-glucan appears to involve stimulation of the innate immune system through increased cytokine release and CR3 receptor activation. Beta (1,3)-glucan is pharmaceutically stable, relatively compact, and can also be used without significant side effects. Beta (1,3)-glucan can also enhance the effectiveness of other medical countermeasures such as antibiotics, vaccines, and immune antibodies.
