Abstract
Strains of Bacillus thuringiensis were isolated from various food item s (pasta, pitta bread and milk) and were found to belong to either H-s erotype kurstaki or neoleonensis. The strains were bioassayed against Pieris brassicae and insecticidal activity of strains was found to cor respond to the presence of the cryl A-gene. All strains, except-one, w ere found to express cytotoxic effects on Vero cells as; an indicator of enterotoxin activity. Further, the B. thuringiensis strains HD-1 (s erotype Kurstaki), NB-125 (serotype tenebrionis) and HD-567 (serotype israelensis) which are used commercially for insect pest management, w ere also found to have cytotoxic effects on Vero cells.
