Antibiotic Action of Protein Parasporal Crystals of Bacillus Thuringiensis on Opportunistic Pathogenic Bacteria of the Large Intestine Microbiota of Animals
The protein solution of parasporal crystals (δ -endotoxin) B. thuringiensis subsp. kurstaki Z-52 has an antimicrobic effect on some bacteria isolated from the large intestine microbiota of white mice. Bactericidal and bacteriostatic effect of δ -endotoxin B. thuringiensis against Enterobacteriaceae Esherichia coli, Salmonella spp., and Staphylococcus – Staphylococcus aureus and Staphylococcus epidermidis – was determined.
