Evaluation of the antimicrobial activity of purified Spodoptera littoralis Phenol Oxidase in vitro

Abstract

Insect innate immune system comprises humoral and cellular defense mechanisms organized differently depending on the insect species and the type of microbial invasion. Humoral defenses against pathogens depend on pathogen receptors that activate the immune response, including the production of defense peptides as antimicrobial peptides (AMPs) and enzymes such as prophenoloxidases (PPOs) and lysozymes.
