Cryptosporidiosis: Symptoms, Causes, Prevention, and Treatment

WebJan 4, 2024 · Several research articles proved that Bt synthesizes Cry toxins terminating the growth of pathogenic insect larvae. Controlling crop and disease insects, Bt secretes parasporal crystal protein known as Cry toxins that have high toxicity towards specific orders of pathogenic insects. WebCry proteins associated with the spore surface allow B. thuringiensis spores to bind brush border membrane vesicles prepared from lepidopteran insects, and the binding has been proposed to be responsible for stimulation of alkali-activated germination . It should be noted however, that the spore surface – Cry protein association may simply ... earned income credit 2023 for seniors
