[Comparative action of solubilized crystals of H-14 and H-1 serotypes of Bacillus thuringiensis on cultures of Aedes aegypti cells].

Abstract

Crystals isolated from Bacillus thuringiensis serovar thuringiensis (H-1) and from serovar israelensis (H-14) were dissolved in sodium hydroxide, then tested in vitro on Aedes aegypti cell cultures. Toxic action was followed after morphological and metabolic alterations of the treated cells. Only the israelensis sodium extract was toxic and gave cellular swelling, inhibition of cell growth and inhibition of labelled precursor incorporation, i. e. of 3H-thymidine, 3H-uridine and 3H-leucine.
