Bacillus thuringiensis
Ba·cil·lus thu·rin·gi·en·sisa bacterial species that is an insect pathogen used for vector control that has been implicated in human and mammalian infections. In the laboratory it may be misdiagnosed as a strain of Bacillus cereus.Bacillus thuringiensis (Bt) an entomopathogenic BACILLUS species that produces a TOXIN called delta (8) endotoxin, which kills insect larvae. The organism is used as a microbial INSECTICIDE for the BIOLOGICAL CONTROL of various LEPIDOPTERA. Genes for the toxin have been transferred to plants by GENETIC ENGINEERING techniques to make them insect-tolerant. See also BIOPESTICIDE.AcronymsSeebad trip |
