[Genetic properties of the nonflagellar Bacillus thuringiensis mutant]. / Geneticheskie svoistva bezzhgutikovogo mutanta Bacillus thuringiensis.

The nonflagellar mutant has been selected in Bacillus thuringiensis strain 33-69 var. galleriae. The absence of flagella in the mutant cells is confirmed by electron microscopy, by the specific "trench transit" test. The mutant preserved the biochemical characteristics of the parent strain, possesses the same phage sensitivity but lower sporulation ability. Fla+ phenotype is cotransduced with the His+ one in general transduction.
