Bacillus cereus/Bacillus thuringiensis
1998Bacillus cereus/Bacillus thuringiensis (B.t.) are spore-forming soil bacteria, the only established difference being the production by B.t. of insecticidal toxins, present as intracellular crystals during sporulation (Aronsen, 1993; Priest, 1981; Carlson & Kolsto, 1993; Carlson et al., 1994.) B.t. is the most widely used biopesticide in the world today.

Bacillus thuringiensis andBacillus sphaericus biopesticides production
Journal of Basic Microbiology, 2006The long residual action and toxicity of the chemical insecticides have brought about serious environmental problems such as the emergence and spread of insecticide resistance in many species of vectors, mammalian toxicity, and accumulation of pesticide residues in the food chain.

Virulence of Bacillus thuringiensis
2000Bacillus thuringiensis and B. cereus are genetically and phenotypically indistinguishable, except for the plasmid encoded ability of B. thuringiensis to produce insecticidal parasporal inclusion bodies (Cry toxins). Some B. cereus are known to cause diarrhoeal and emetic symptoms in humans, but also somatic infections have been reported.
