J. Clin. Microbiol. 45, 3316-3322. Evaluation the Invader Assay with the BACTEC MGIT 960 System for prompt isolation and identification of Mycobacteria from clinical specimens. 2007

Ichimura, S., Nagano, M., Ito, N., Shimojima, M., Egashira, T., Miyamoto, C., Ohkusu, K., and Ezaki, T.

Notes: These authors compared standard culture conditions, DNA isolation and analysis (e.g, sequencing) with a liquid culture, DNA isolation and a homogeneous fluorescent detection system for identifying mycobacterial species. The standard DNA extraction began with a loopful (3–mm3 sphere) of bacterial colony grown on Ogawa slants that used glass beads to mechanically disrupt the cells. The resulting lysate was extracted using phenol/chloroform, and DNA purified from the aqueous phase using a robotic liquid handler AGE-96 (Biotec) and the MagneSil® Blood Genomic, Max Yield System. The DNA extractions were used in PCR and sequencing reactions. (3700)

J. Assoc. Lab. Automation 8(6), 113-120. Robotic nucleic acid isolation using a magnetic bead resin and an automated liquid handler for biological agent simulants. 2003

Bailey, A.M., Pajak, L., Fruchey, I.R., Cowan, C.A. and Emanuel, P.A.

Notes: This study describes the development of a system that can rapidly and accurately detect traces of biological agents from environmental samples. Using Erwinia herbicola and Bacillus subtilis var. niger as models for potential biological warfare agents, a method for DNA extraction using the Wizard® Magnetic DNA Purification System for Food, MagneSil® Blood Genomic, Max Yield System and a combination of the two was automated on a Beckman Coulter Biomek® FX robotic liquid handling system. The isolated DNA was used in a Taqman® real-time PCR assay that specifically amplified and identified DNA species. The ability of the MagneSil®-based DNA purification technology to eliminate PCR inhibitors was also evaluated. Various soil samples, surface swabs and air samples were mixed with bacterial cultures to see if any contaminants present in the samples inhibited PCR. It was found that the modified MagneSil® method described here eliminated many PCR inhibitors. (3094)
