The parasporal crystals of Bacillus pumilus strain 15.1: a potential virulence factor? [PDF]

open access: yes, 2017
Bacillus pumilus strain 15.1 was previously found to cause larval mortality in the Med-fly 27 Ceratitis capitata and was shown to produce crystals in association with the spore.

Hematotoxicity of bacillus thuringiensis as spore-crystal strains cry1aa, cry1ab, cry1ac or cry2aa in swiss albino mice [PDF]

open access: yes, 2013
Formulated and sporulated cultures of Bacillus thuringiensis (Bt) have been widely used against insect pests, but after the advent of genetically modified plants expressing δ-endotoxins, the bioavailability of Cry proteins has been increased.

Insecticidal Effects of Hemocoelic Delivery of Bacillus thuringiensis Cry Toxins in Achaea janata Larvae

open access: yesFrontiers in Physiology, 2017
Insecticidal effects of Bacillus thuringiensis Cry toxins in hemocoel of larvae have not been properly evaluated. In the present study, hemocoelic injection of four representative Cry toxins i.e., Cry1Aa, Cry1Ab, Cry1Ac, and DOR5 to an economically ...

Enzymatic activity of Bacillus thuringiensis toxins

open access: yes, 2016
When sporulating, Bacillus thuringiensis produces paracrystalline inclusions containing one or more proteins which are mainly responsible for the entomopathogenic properties of this bacterium. Such proteins mostly belong to the Cry family which, after spore lysis and solubilization of the crystals, are delivered to specific zones of the gut. Then, they

Cloning and Characterization of a Unique Cytotoxic Protein Parasporin-5 Produced by Bacillus thuringiensis A1100 Strain

open access: yesToxins, 2014
Parasporin is the cytocidal protein present in the parasporal inclusion of the non-insecticidal Bacillus thuringiensis strains, which has no hemolytic activity but has cytocidal activities, preferentially killing cancer cells.

A Shared Receptor Suggests a Common Ancestry between an Insecticidal Bacillus thuringiensis Cry Protein and an Anti-Cancer Parasporin

open access: yesBiomolecules
Cry toxins, produced by the bacterium Bacillus thuringiensis, are of significant agronomic value worldwide due to their potent and highly specific activity against various insect orders.
