The most common organism causing wound infections is:

• A. Candida
• B. Staph
• C. Neisseria
• D. HBV

Answer: (B)

Staphylococcus aureus is the most common cause of wound infections because it is a frequent inhabitant of the skin and nasal passages, making it easy for it to contaminate and invade a wound once the skin barrier is breached. Its ability to adhere to tissue, form protective biofilms, and resist immune defenses helps it establish infection readily, so it remains the leading pathogen in many wound cases. Candida can cause wound issues, especially in chronic or immunocompromised situations or after extensive antibiotic use, but it is not as prevalent as bacterial pathogens in typical wound infections. Neisseria mainly affects mucosal sites and systemic infections rather than standard wound infections. HBV is a hepatitis virus and does not cause wound infections.
