Advanced LAMDAC™ technology recovers higher levels of pathogens than traditional methods

BLUFFDALE, Utah, January 3, 2007 — Microbial-Vac Systems®, Inc., the leading innovator in pathogen surface sampling, has released for purchase the latest technology in pathogen collection.  The Microbial-Vac (M-Vac™) wet-vacuum collection system utilizes LAMDAC™ principles (Liquid and Air-assisted Microbial Detachment and Capture) to collect laboratory or field samples—typically from one-to-two square feet of surface area per sample in 100-150 ml liquid.  The M-Vac is designed to sample this larger area while recovering higher levels of pathogens in each sample than traditional methods.

Validation tests have demonstrated the pathogen recovery rate of the M-Vac to be up to 90 percent higher than traditional sampling methods.  Because the M-Vac reduces materials required for sampling, lab processing and detection, it has also proven to be a cost- and resource-effective method.  Studies from major universities and research centers have shown the M-Vac to return a statistically significant increase in recovery of low-inocula bacteria from cantaloupe rinds, carpet, meat carcasses and a variety of other common surfaces. These studies demonstrate the M-Vac to be notably higher in accuracy than sponge and swab techniques, and statistically equal to or higher than the “Gold Standard” of excision.

The development of the M-Vac began in response to the E. coli O157:H7 outbreaks in the 1990s when Dr. Bruce J. Bradley first began developing the M-Vac in his privately owned microbiology testing laboratory, Rocky Mountain Resource Labs, Inc., in Jerome, ID.  Raised on a beef cattle ranch and having spent many hours working in a university meat-processing lab, Dr. Bradley suspected a major component of false negative lab results could be traced to the sampling process.  From that idea, he developed the first generation non-destructive surface sampling device, which could collect bacterial pathogens at levels similar to the excision method.  In 2002, Dr. Bradley moved his research operation into a new, separate R&D corporation.  His team at Microbial-Vac Systems, Inc. continues to work on future generations of the system.
