In subsequent episodes of PID, other aerobic and anaerobic organisms may be the causative agent to the pelvic infection (T. pyogenes, Bacteroides bivius, F. nucleatum, Actinomyces israelii ) One of the hallmarks of infection by anaerobic bacteria, including Bacteroides, is an exudate with a rather characteristic putrid odour, although the absence of such an odour does not preclude an anaerobic infection. 6, 48 The odour is primarily the result of metabolic end.

  1. Actinomycosis is a subacute or chronic infection due to Actinomyces israelii or one of several other Actinomyces species. The body's reaction tends to be granulomatous or suppurative. Hematogenous spread can occur to distant sites but lymphatic spread is uncommon. The 3 major anatomic types of actinomycosis are cervicofacial, thoracic, and.
  2. At present there are over two dozen genera of Gram-negative anaerobic bacilli. In most clinical infections, only the genera Bacteroides, Prevotella, and Fusobacterium need be considered. These genera are prevalent in the body as members of the normal flora (Fig.20-1), constituting one-third of the total anaerobic isolates from clinical specimens, and may become involved in infections.
