Abstract
Streptomycin-resistant strains (StrR) of the entomopathogenic bacteria Bacillus thuringiensis ssp. galleriae (Btg) have been obtained. Assessment of growth rate of Btg 69-6 colonies revealed significant difference between the initial strain StrS sensitive to antibiotics and StrR. Decrease in susceptibility of instar IV larvae of Galleria mellonella to Btg 69-6 StrR by a factor of eight compared to Btg 69-6 StrS has also been recorded. In Btg 190 StrR, the insecticidal activity decreased by a factor of five. In StrR, the biochemical properties changed after acquisition of resistance compared to the initial strain.
