Effect of sub-lethal doses of Bacillus thuringiensis subsp. Aizawai and deltamethrin with regard to fertility and organ toxicity in pregnant albino rats.

Products with Bacillus thuringiensis (Bt) and synthetic insecticides have been widely used against important vectors of human diseases. However, few studies have addressed the application of these substances on the female reproduction apparatus during pregnancy at doses that do not cause clinical symptoms of intoxication. Seventy pregnant albino rats were analyzed with regard to fertility and histopathology of the kidneys, liver and lungs as well as the morphology of the neonates.
