Bacillus thuringiensis (Bt) ke baktheria ea gram-positive.Ke baahi ba mefuta e fapaneng.Ho ea ka phapang ea antigen ea eona ea flagella, Bt e ka thōko e ka aroloa ka 71 serotypes le 83 subspecies.Litšobotsi tsa mefuta e fapaneng li ka fapana haholo.
Bt e ka hlahisa mefuta e sa tšoaneng ea likaroloana tsa intracellular kapa extracellular bioactive, tse kang liprotheine, nucleosides, amino polyols, joalo-joalo Bt haholo-holo e na le ts'ebetso ea likokoana-hloko khahlanong le lepidoptera, diptera le coleoptera, ho phaella ho mefuta e fetang 600 e kotsi ho arthropods, platyphyla, nematoda le protozoa, le mefuta e meng e na le ts'ebetso e bolaeang likokoanyana khahlano le lisele tsa mofetše.E boetse e hlahisa lintho tse sebetsang tsa proto-bacterial tse hanyetsanang le mafu.Leha ho le joalo, ho feta halofo ea li-subspecies tsohle tsa Bt, ha ho mosebetsi o fumanoeng.
