History

Since 1986, Dr. Lawrence Restaino has been a leader in the development of chromogenic media for the isolation and identification of food pathogens. In 1990, R & F Laboratories was started by Dr. Restaino who quickly realized that the standard plating media and enrichment broths for pathogen isolation was ineffective for operating an efficient laboratory. By 1995, Dr. Restaino started substituting the standard media with newly developed and tested chromogenic plating media which provided a simpler, more innovated approach to detect/enumerate pathogenic bacteria accurately allowing a more efficient and productive laboratory.

New Chromogenic Plating Medium!

R & F® Products, Inc. would like to introduce a new chromogenic plating agar – the R & F® Bacillus cereus Group (BCG) Chromogenic Plating Medium. This medium can easily enumerate and isolate 9 important species within the Bacillus cereus Group. Typical Bacillus cereus Group species produce dark turquoise colored colonies (color stays within the colony- no opacification halos as observed on competing agars), and range from 1-5 mm in diameter, with or without a thin clear ring after plate incubation at 35°C for 24-28 hours.


The BCG chromogenic agar utilizes a chromogenic substrate that targets the enzyme phosphatidylcholine-specific phospholipase C (PC-PLC), which is an important virulence factor specific to the B. cereus Group.


The plating medium is readily available upon request. To place an order or to find pricing and availability, please call us at (630)969-5300 or email at rf@rf-products.net. The catalog numbers for the R & F® Bacillus cereus Group (BCG) Chromogenic are as follows:
