PATHOGENS
- Staphylococci account for >50% of total prosthetic joint infections (PJI). Gram negatives may account for 15%. Approximately 20% may be polymicrobial.
- Culture-negative infections represent ~7-11% of infections; some may be due to prior abx therapy.
- Bacterial:
- Staphylococcus (coagulase-negative)
- Staphylococcus aureus
- Viridans streptococci
- Cutibacterium acnes (especially shoulder implant infections, formerly Propionibacterium)
- Enterococcal species
- Gram-negative enteric bacteria
- Pseudomonas aeruginosa
- Anaerobes
- Brucella spp (rare)
- Mycobacterial:
- Non-tubercular mycobacteria (rare)
- M. tuberculosis (very rare)
- Fungal:
- Candida species
- Typical pathogens by the time of onset following prosthesis placement:
- Early infection (0-3 months post-op): predominantly S. aureus, β-hemolytic streptococci, Gram-negative bacilli, polymicrobial infection, anaerobic
- Delayed (3 mos-2 yrs): usual pathogens include coagulase-negative Staphylococci,S. aureus,C. acnes, Enterococcus spp.
- Late (>2 yrs): S. aureus, coagulase-negative Staphylococci, viridans Streptococci, Enterococci, C. acnes
- Less common: Gram-negatives
