Abstract：
:This study investigated the various commercially available kits and 'in-house' methods to extract DNA from Gram-negative and Gram-positive bacteria, yeast and fungal agents in commonly employed blood culture material. The main methods investigated were as follows; Qiagen QIAmp Blood kit, Roche high PCR template preparation kit, Puregene DNA extraction kit, boiling, glass beads/sonication and wash/alkali/heat lysis. The results indicated that a simple wash/alkali/heat lysis method was the most sensitive, reproducible, simple and cost-effective extraction method. This was the only method which removed any PCR inhibitors and inherent DNA which existed in virgin BacT/Alert aerobic, anaerobic and paediatric blood culture material. Contaminating microbial DNA from Lactococcus lactis or Bacillus coagulans was identified in all batches of BacT/Alert FAN aerobic blood culture material examined.
