Methods for Reducing Bacterial Contamination in the BacT/Alert Mycobacterial Culture Detection System

摘要

Two methods were compared for decreasing bacterial contamination in the BacT/Alert mycobacterial culture detection system. Two concentrations, 0.5 ml (standard amount) and 1.0 ml, of mycobacterial antibiotic supplement were evaluated. Contamination rates were 14% and 6% for the standard and the doubled concentrations, respectively. This difference was statistically significant (P < 0.005).
