The influence of inactivated entomopathogenic bacterium <i>Bacillus thuringiensis</i> on the immune responses of the Colorado potato beetle.

ABSTRACT:

Background

Invasion of microorganisms into the gut of insects triggers a cascade of immune reactions accompanied by increased synthesis of effectors (such as antimicrobial peptides, cytokines, and amino acids), leading to changes in the physiological state of the host. We hypothesized that even an inactivated bacterium can induce an immune response in an insect. The aim of this study was to compare the roles of reactive oxygen species (ROS) formation and of the response of detoxification and antioxidant systems in a Colorado potato beetle (CPB) larval model in the first hours after invasion by either an inactivated or live bacterium.

Methods

The influence of per os inoculation with inactivated entomopathogenic bacterium Bacillus thuringiensis var. tenebrioni
