FIG. 2.

Antimicrobial susceptibility patterns generated by direct inoculation of a positive blood culture into the Bactometer. The growth curves were monitored by detecting changes in impedance during incubation. It was evident that the microorganism (E. coli 8892) in the blood culture was resistant to ampicillin (curve B) and ciprofloxacin (curve C) but susceptible to gentamicin (curve D). It is noteworthy that the DT for the positive control (no antibiotic in the inoculated well; curve A) was only 2.3 h.
