The hepatitis B virus (HBV) infection represents
a global health problem; it can be transmitted through contact
with infected blood or other body fluids and it is dangerous
being highly contagious. Hepatitis B is preventable with effective
vaccine, as it is strongly recommended by the World
Health Organization; its protection is possibly life-long, at least
20 years. Mathematical modelling is a useful tool to study the
evolution of an epidemic spread and possibly to suggest suitable

In recent years, the multi-drug resistance of bacteria and fungi strains has become a worldwide problem. The incidence of fungal and bacterial infections is experiencing a serious growth and the microorganisms have developed several new mechanisms of antibiotic resistance. Antimicrobial peptides (AMPs) constitute one of the well-known barrier defense systems of plants. They have been isolated from roots, seeds, flowers, stems and leaves of a wide variety of species and have activities towards phytopathogens, as well as against human pathogens.
