Orthopaedic Jobs

Anaerobic Joint Infections:

- Discussion:
     - see bacterial menu
     - Peptostreptococcus magnus, Bacteroides fragilis, Fusobacterium, Porphyromonas, Actinobacillus, Eikenella and proprionobacter acnes;
     - uncommon cause of septic arthritis (in over 80% of cases, the infection occurr after surgery or trauma, and in patients receiving steroids)

     - Gram-negative anaerobes: 
              - Bacteroides (the most commonly found anaerobes in cultures; intra-abdominal infections, rectal abscesses, soft tissue infections, liver infection)
              - Fusobacterium (abscesses, wound infections, pulmonary and intracranial infections) 
              - Porphyromonas (aspiration pneumonia, periodontitis) 
              - Prevotella (intra-abdominal infections, soft tissue infections)
                    - Septic arthritis of the knee due to Prevotella loescheii following tooth extraction

      - Gram-positive anaerobes: 
              - Actinomyces (head, neck, pelvic infections; aspiration pneumonia) 
              - Bifidobacterium (ear infections, abdominal infections) 
                    - Antibiotic Susceptibility of Lactobacillus and Bifidobacterium Species from the Human Gastrointestinal Tract
                    - Antimicrobial susceptibility of bifidobacteria 
              - Clostridium (gas, gangrene, food poisoning, tetanus, pseudomembranous colitis) (see difficile)
              - Peptostreptococcus (oral, respiratory, and intra-abdominal infections) 
                    - Destructive Knee Joint Infection Caused by Peptostreptococcus micros: Importance of Early Microbiological Diagnosis
              - Propionibacterium (shunt infections)
              - reference:
                    - Gram-Positive Anaerobic Cocci
       
MIC values (mg/L) for GPAC species or groups against 10 antimicrobial agents
