Insect antimicrobial peptides: isolation, separation and antimicrobial activity

In modern conditions of intensification of agriculture the industrial animal breeding involves the use of antibacterial drugs aimed at the prevention of infectious diseases. However, uncontrolled use of antibiotics leads to the selection of antibiotic-resistant strains, it should be noted that the t...
