Publication number: 20240148800Abstract: 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.Type: ApplicationFiled: October 12, 2023Publication date: May 9, 2024Inventors: Raffi Van Aroian, Gary R. Ostroff

Publication number: 20230128953Abstract: Compositions and methods for treating or reducing the severity or likelihood 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 killed or inactivated recombinant bacterium expressing a crystal protein such as a Bacillus thuringiensis crystal protein (Cry) in the cytosol of the bacterium. 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. The recombinant bacteria may be treated with an anti-microbial agent before or during administration to a subject.Type: ApplicationFiled: September 23, 2022Publication date: April 27, 2023Inventors: Raffi Van AROIAN, Gary R.
