InTray SMA (Sorbitol MacConkey Agar) is a selective and differential media for the detection of sorbitol-non-fermenting Escherichia coli serotype O157:H7 associated with hemorrhagic colitis. This medium is also referred to as “MacConkey Sorbitol Agar”.

Escherichia coli serotype O157: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 Escherichia coli. Field results show that the growth of Escherichia coli O157: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 Escherichia coli O157:H7 in stool cultures.

Specifications

Product Principle
  • Durable injection molded device
  • Highly selective media designed for growth, transport and result
  • Sealed environment with Tyvek® air filtration
  • Resealable media well reduces exposure and contamination
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

Storage

InTray SMA has a shelf life of 12 months from the date of manufacture.

Upon receipt, store InTray SMA (Sorbitol MacConkey Agar) under refrigeration (2-8°C). Medium can be kept for one day at ambient temperature. Avoid freezing or prolonged storage at temperatures above 40°C. Do not open until ready to use. Do not use if the medium shows signs of deterioration or contamination.

Features and Benefits

Shelf-life and durability

  • Designed for long shelf life, durability and stackable for incubation, or 12 month storage. 
  • No re-plate or wet mount 
  • Once InTray is inoculated, no other culture preparation is required... saving time and cost. 
  • Designed for specimen collection/inoculation at point-of-care, a fully enclosed system for transport, incubation, result and microscopic observation. 
  • The sealed prepared media device is selectively formulated for accurate detection and identification of pathogens and non-pathogens

Key Features

  • Fully enclosed cassette with air filtration system
  • Nutritive culture colony growth medium, formulated for selectivity and specificity 

You'll immediately experience a reduction in:

  • Time-to-result
  • Cost of laboratory materials 
  • Medical waste
  • Risk of exposure or contamination
