Answer

Factors in the microbiologic diagnosis and assessment of Enterobacter infection include the following:

  • The most important test to document Enterobacter infections is culture; when the patient presents with signs of systemic inflammation (eg, fever, tachycardia, tachypnea) with or without shock (eg, hypotension, decreased urinary output), blood cultures are mandatory

  • Direct Gram staining of the specimen is also useful, because it allows rapid diagnosis of an infection caused by gram-negative bacilli and helps in the selection of antibiotics with known activity against most of these bacteria

  • In the laboratory, growth of Enterobacter isolates is expected to be detectable in 24 hours or less; Enterobacter species grow rapidly on selective (ie, MacConkey) and nonselective (ie, sheep blood) agars
