Action comparée des cristaux solubilisés des sérotypes H-14 et H-1 de Bacillus thuringiensis sur des cultures de cellules de Aedes aegypti

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.
