The differences between conventional Bacillus thuringiensis strains and transgenic insect resistant plants: Possible reasons for rapid resistance development and susceptibility of non-target organisms
Text: B. thuringiensis (Bt) was discovered by Ernst Berliner in 1911 when a consignment of flour moths sent in from Thuringia was found to be infected by some contagious pathogen. After some more properties of this Bacillus species had been identified, including its host specifity, it did not take long until first experiments were being carried …
Bacillus thuringiensis (BT): Insecticide fact sheet
Abstract: Bacillus thuringiensis (B.t.) is a live microorganism that kills certain insects and is used to kill unwanted insects in forests, agriculture, and urban areas. In a purified form, some of the proteins produced by B.t. are acutely toxic to mammals. However, in their natural form, acute toxicity of commonly-used B.t. varieties is limited to …
An overview of the safety and biological effects of Bacillus thuringiensis Cry toxins in mammals
Abstract: Crystal proteins (Cry) produced during the growth and sporulation phases of Bacillus thuringiensis (Bt) bacterium are known as delta endotoxins. These toxins are being used worldwide as bioinsecticides to control pests in agriculture, and some Cry toxins are used against mosquitoes to control vector transmission. This review summarizes the relevant information currently available regarding the …
