Alain Rambach, founder of CHROMagar™ – Alain Rambach has devoted his life to pioneering science with entrepreneurialism, education, and invention. Having studied at Ecole Polytechnique, Stanford University, the Pasteur Institute, and even with Nobel Prize winning geneticist, Professor Francois Jacob, Dr. Alain Rambach has almost 50 years of experience influencing the development of modern science.

Chromogenic Microbiology: A Brief History

Chromogenics was first introduced to the public with the invention and patent for detecting E. coli bacteria by method of “chromogenic differentiation” culture media. By 1989, the chromogenic system to detect the Salmonella pathogen, Rambach Agar, was patented. Four years later in 1993, Rambach founded and incorporated CHROmagar™ Microbiology and headed the CHROmagar™ research and development.

CHROMagar™ Technology: How it works

CHROMagar™ TechnologyThe invention of Rambach Agar and its inclusion into the modern science laboratory has opened the doors to quick efficiency with no need for subcultures. CHROMagar™ technology is based on soluble colorless molecules called chromogens. Chromogens consist of a substrate (used to target specific enzymatic activity) and a chromophore. The targeted organism’s enzyme will cleave, or split the colorless chromogenic conjugate, and in its unconjugated form, the chromophore will reveal a specific color. There is no more need for perfect lighting or uncertainty in the lab with CHROMagar™. The distinct colors make it easy to view results and continue on with testing.

Common Chromogenic Media: E.coli

  1. coli (Escherichia coli) can indicate the presence of faecal matter contamination in food and water. Many factors can lead toE.coli contamination making the monitoring of food and water processing essential to ensure safety of both the product and consumer. High contamination can suspend water supplies, recall food products, and cause illness if ingested. Faecal contamination can be indicated by the presence of E.coli that can lead to the potential presence of bacteria such as Vibrio cholerae, Salmonella, Pseudomonas, and many more dangerous pathogens. E.coli presence can also indicate the presence of potentially life-threatening viruses and intestinal parasites. There is no time to waste when testing for E.coli which is why DRG International, Inc. not only recommends its use but is proudly the authorized dealer of CHROMagar™.

Enumeration of E.coli Detection Made Easy

CHROMagar™ E.coli media contain 5% more agar than any other media available.

Enumeration of E.coli Detection Made EasyThis helps with the application and streaming of the sample onto the plate an easier process. Traditional non-CHROMagar™ methods of E.coli detection are time consuming and tedious, requiring the study of multiple colonies. With CHROMagar™, colonies of E.coli develop with an easy-to-identify blue color. CHROMagar™ eliminates the need for a specifically lit environment to read results and can help quickly and efficiently determine presences of the possible life-threatening E.coli. Typical samples are raw materials, processed food, water, environmental samples, and milk/ dairy products.

Salmonella:

The Detection and Isolation in Clinical Specimens & Food Samples

In addition to E.coli, some more common health threats to the world are the potential infections caused by the presence ofSalmonella, S. typhi, and S. paratyphi. In 2008, a CDC estimation found Salmonella to have an incidence rate of 16.2 cases per 100,000 in the US. According to a 2007  EFSA report, developing countries encounter Salmonella typhi and paratyphi at a rate of about 17 million cases per year.  These cases are most often due to food contamination, Salmonella most commonly induces enteric illness. Symptoms may include abdominal cramps, diarrhea, nausea, and vomiting. A recent WHO report found thatSalmonella infections are responsible for 2-million deaths per year from diarrhoea. Testing for the presence of Salmonella, S. paratyphi, and S. typhi needs to be as timely and efficient as possible to allow for the focus to remain on the contamination and not with the unnecessary steps of the testing procedure. Food samples can be tested for Salmonella and lactose positiveSalmonella with CHROMagar™ Salmonella Plus. Clinical specimens can be tested for Salmonella with CHROMagar™Salmonella .

Easy to Read: Color Contrast
Detects Salmonella in food samples including S. typhi, S paratyphi A, and lactose positive Salmonella in a muave color.
Coliforms will turn an easy-to-read blue color.

  1. coli will remain colorless.

Proteus will remain colorless or inhibited.

Easy to Read: Color Contrast
Detects Salmonella in clinical specimens including S. typhi in a muave color.Other bacteria will turn an easy-to-read blue, colorless, or inhibited.

CHROMagar™ Salmonella and  CHROMagar™ Salmonella save time by eliminating the unnecessary examination of multiple suspect colonies in a given sample. The easy-to-read coloured results make it easy to choose  CHROMagar™ products and why DRG International, Inc. is an authorized distributor.
