Answer

Because colonization is the rule and infection is the exception, colonized patients have no associated physical findings.

Patients with Acinetobacter infection have signs and symptoms related to the organ system involved, ie, wound infection, episodic outbreaks of nosocomial pneumonia, CAPD-associated peritonitis, nosocomial meningitis, or catheter-associated bacteruria.

The following is summarized from an article by Go and Cunha (1999): [4]

  • Acinetobacter commonly colonizes skin, oropharynx secretions, respiratory secretions, and urine.

  • Acinetobacter uncommonly colonizes the gastrointestinal tract and is associated with nosocomial pneumonias (which usually occur as outbreaks), bacteremias, and wound infections.

  • Acinetobacter infection is rarely associated with meningitis, endocarditis (native valve infective endocarditis and prosthetic valve endocarditis), peritonitis, urinary tract infections, community-acquired pneumonia, and cholangitis.
