[Use of the restriction analysis in the quality control of the strain of Cuban biolarvicide BACTIVEC].

The genomic characterization of the strain used in manufacturing biolarvicide BACTIVET was shown in this paper. Digestion patterns of Bacillus thuringiensis reference strain 266 from the collection of Pushkin Institute located in former Leningrad and of two strains isolated from 2 batches of biolarvicide were compared. Chromosomal DNA digestion was performed by enzymes Hindlll and EcoRI. The same restriction pattern was observed in all cases, which is indicative of genetic stability of the active ingredient of biolarvicide BACTIVET.
