Answer

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. After growth in blood or on agar plates has been confirmed, the bacterial colonies are identified through various, usually automated, methods. When identification of a particular isolate is difficult, newer molecular (rRNA or PCR) methods can be used in certain laboratories
