Background

Microbiology

  • Non-motile, aerobic, oxidase negative, non-fermentative, Gram-negative coccobacillus
  • Member of the genus Acinetobacter with low pathogenicity

Epidemiology

  • Rare cause of disease in humans
  • Mostly affects immunocompromised patients or critically ill patients
  • Possible association with malignancy

Clinical Manifestations

Management

  • Often susceptible, but should still treat broadly (e.g. meropenem) and narrow based on susceptibilities
