Answer

Staphylococcus aureus remains the most common infectious agent in people who abuse intravenous drugs. However, a high rate of infections with gram-negative organisms, especially Pseudomonas aeruginosa and Serratia species, occurs in cases of septic arthritis. In addition, a higher rate of fungal and anaerobic infections occurs. Unusual locations, such as the sternoclavicular joint, are involved.
