Staphylococcus aureus : Pathogenesis, Drug Resistance, and Therapeutics

This book presents a comprehensive overview of intricate mechanisms of virulence, antimicrobial resistance, immune evasion, and biofilm formation of Staphylococcus aureus. It provides insights into mechanisms by which S. aureus acquires and sustains drug resistance, including gene mutation, efflux pumps, and horizontal gene transfer. The book examines the latest advancements in pathogen detection, application of artificial intelligence, and systems biology approaches in S. aureus research. In addition, the book examines host immune responses to persistent S. aureus infections, focusing on immune modulation, chronic inflammation, and evasion mechanisms. Further, the chapters review novel therapeutic interventions, including quorum-sensing inhibitors, plant-derived antimicrobials, and innovative vaccine development. By integrating genomic research, computational biology, and emerging drug discovery techniques, this book outlines the next generation of treatment options for S. aureus-related infections.

Key Features:

• ·Explores the molecular and genetic mechanisms underlying S. aureus virulence, drug resistance, and host adaptation
