Introduction

Since their discovery, antibiotics have helped millions of people overcome previously lethal bacterial infections, and these drugs are considered among the greatest of medical achievements. Both natural and synthetic antibiotics are used to treat or prevent bacterial infections in humans and domesticated animals.

Bacteria and fungi produce antibiotics to communicate with each other and to establish themselves in or to survive different ecological niches (Hibbing et al. 2010; Watve et al. 2001).

Antibiotics are small molecule compounds that vary widely in their structures (Fig. 1). The widespread use of these compounds has led to bacteria...
