E. coli O157:H7

InTray® SMA - Prepared Plated Culture Media for E. coli O157:H7

Sorbitol MacConkey Agar (SMA) is a selective and differential media for the detection of sorbitol-non-fermenting Escherichia coli serotype 0157:H7 associated with hemorrhagic colitis. This medium is also referred to as "MacConkey Sorbitol Agar."

E. coli serotype 0157:H7 is a human pathogen associated with hemorrhagic colitis that results from the action of a shiga-like toxin. On standard MacConkey Agar containing lactose, this strain is indistinguishable from other lactose-fermenting E. coli. Field results show that the growth of E. coli 0157:H7 on SMA is heavy and occurs in almost pure culture-- as colorless sorbitol-non-fermenting colonies. Most organisms of the fecal flora ferment sorbitol and appear pink on this medium. SMA, therefore, permits ready recognition of E. coli 0157:H7 in stool cultures.

Specifications

Product Principal

Combine collection, culture, result and microscopic observation in one IVD device.
Highly selective prepared media in a device designed for in-vitro specimen transport and incubation.
Rapid presumptive-positive diagnosis without re-plating. Intray can be placed directly on microscope stage
Fully enclosed cassette with Tyvek® air filtration prevents contamination and exposure, post-collection.

Simple Convenience

The InTray is designed for specimen collection/ inoculation at point-of-care
Saves time, material cost and waste, reducing exposure to collected sample
Place directly on the microscope tray for observation through the cassette’s clear anti-fog window
Selectively produces distinctive colony growth with typical identifiable morphology
