Symbiotic infections

---

- Discussion:
    - caused by non hemolytic Strep and hemolytic Staph aureus;
    - although staph alone may show up on culture, special attention may
          must be paid to isolating the microaerophilic Streptococceae;
    - necrotizing fascitis may occur, especially in diabetics;
    - any hand infection that does not respond to local drainage, wet
          dressings, and antibiotics should be suspected of having a
          symbiotic infection;
    - if special techniques are not used, the diagnosis of a symbiotic
          infection will be missed, and Staph aureus, Bacillus pyocyaneus,
          Proteus, and Enterococci will predominate on culture;
