Microbial pathogenesis is the intricate interaction between host and microorganism that significantly impacts the health of the host. This chapter explores the dual perspective of the pathological outcome of this interaction which is directly involved to the level of harm imposed on the host and emphasizing the complex interplay of microbial factors along with the host’s response. The pursuit of innovative strategies becomes imperative due to the constant threat of microbial pathogenesis remains to human health. Therefore, focus on the bioactive compounds and their pivotal role on microbes is a promising option to combat the microbial pathogenesis. The chapter unfolds the diverse array of natural compounds such as alkaloids, flavonoids, and terpenoids which are derived from nature, including plants, microorganisms, and marine life. The study extends to the application of these bioactive compounds as potent antimicrobial agents like antibacterial, antiviral, and antifungal activity. The chapter discoursed the mechanisms of action of bio active compounds, explores their way of interaction and possible combination therapies to enhance the efficacy, and addresses the drugs resistance issues. Challenges and future perspectives are also discussed in association with bioavailability, potential toxicity, and safety. The role of emerging technologies and global collaboration for enhancing the production, research, and development are also discussed. Ultimately, this chapter represents a comprehensive overview of the bioactive compounds in the battle against infectious diseases.
