Rapid'E. coli O157:H7 Agar

Direct presumptive identification of Escherichia coli O157:H7

Intended Use: RAPID’E.coli O157:H7 agar is a selective chromogenic medium for the detection, isolation, and presumptive identification of Escherichia coli O157:H7 in human food products and in environmental samples.

Simple Protocol: The RAPID’E.coli O157:H7 method provides laboratories with a rapid and economical solution for E.coli O157:H7 detection, with 1 plate required per sample. Easy confirmation using latex is also validated from isolated colonies on RAPID’E.coli O157:H7 agar.

Other Protocols: RAPID’E.coli O157:H7 agar can also be used as a second selective medium in different standardized protocols (for example, ISO 16654 reference method)
To confirm positive results of iQ-Check™ E.coli O157:H7 PCR tests

Easy to Read: RAPID’E.coli O157:H7 medium permits detection of Escherichia coli O157 serotype H7 using specific chromogenic substrates and biochemical activities.Typical Escherichia coli O157:H7 (sorbitol and ß-glucuronidase) present characteristic convex 1–2 mm diameter dark blue to black colonies. It is possible to detect atypical ß-glucuronidase + Escherichia coli O157:H7. These strains have characteristic dark blue to black colonies.
Atypical sorbitol + Escherichia coli O157:H7 are also detected.These colonies are blue to turquoise blue.
The selectivity of the medium is improved by adding selective reagents: novobiocin and potassium tellurite.
RAPID’E.coli O157:H7 medium is very specific. Most other bacteria and yeasts are inhibited or present a different color.
