Measurement of the Concentration of Bacillus Anthracis Spores by DNA Content: Comparison to Plate and Microscope Counts and the Use of Inactivated Materials

May 13, 2008

Author(s)

Jamie L. Almeida, Bruce Harper, Kenneth D. Cole

Reliable measurements of the concentration of Bacillus anthracis (BA) spore suspensions are essential for the production of useful reference materials that can be used to test detection devices and laboratory instruments. In this study, we have compared

Long-Term Monitoring of Biofilm Growth and Disinfection Using a Quartz Crystal Microbalance and Reflectance Measurements

September 1, 2006

Author(s)

Vytautas Reipa, Jamie L. Almeida, Kenneth D. Cole

An biofilm reactor was constructed that allows for real-time monitoring of the growth and removal of biofilms by monitoring the response of a quartz crystal mircrobalance (QCM) and a novel method of measuring the reflectance of light off the surface of the

Requirements for the Development of Bacillus Anthracis Spore Reference Materials Used to Test Detection Systems

May 1, 2006

Author(s)

Jamie L. Almeida, Lili Wang, Jayne B. Morrow, Kenneth D. Cole

Bacillus anthracis spores have been used as biological weapons and the possibility of their further use requires surveillance systems that can accurately and reliably detect their presence in the environment. These systems must collect samples, process the
