*Staphylococcus aureus* is a coccus, gram-positive, non-spore forming, and non-motile bacterium. Its commensal and opportunistic capabilities make it able to colonize different sites of animals and humans. Resistance to antibiotics has resulted in development of new strains and new types within strains. Types of methicillinresistant *S. aureus* (MRSA) include hospital-acquired MRSA (HA-MRSA), communityacquired MRSA (CA-MRSA), and livestock-acquired MRSA (LA-MRSA). There are also new strains like vancomycin-resistant *S. aureus* (VRSA) and vancomycinintermediate *S. aureus* (VISA). Expansion in resistance is expected to give rise to newer strains resistant to antibiotics such as macrolide (*erm* gene), tetracycline (*tet* genes), mupirocin (*mupR*), and fusidic acid (*fusD*). Alternative approaches like nanoparticles, bacteriophages, phytochemicals, and more are required to tackle this pathogen. This book contains information on epidemiology, resistance mechanisms, and alternative ways to curtail *S. aureus* infection, as well as future research opportunities*.*
