InTray® COLOREX™ Salmonella

Colorex™ Salmonella allows for simultaneous growth, detection and chromogenic differentiation of Salmonella pathogens, including S. typhi and S. paratyphi, traditionally taken from clinical stool specimens. Additionally, Colorex Salmonella inhibits the growth of yeasts, mold and fungi – resulting in 100% sensitivity and 89% specificity for Salmonella compared to 78% with traditional Hektoen Agar.

Specifications

Product Principle

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
Visual chromogenic differentiation

Accurate Detection

Provides 89% specificity for Salmonella

Test Strain	ATCC #	Colony Appearance

Time to Result

24 - 48 hours, incubate at 37ºC

Storage

Extended 6 months shelf life (2-8°C) from the date of manufacture
Can tolerate extended periods at controlled room temp (≤ 25˚C), with no loss in performance.

Specimen

Skin
Sputum
Urine
Genito-urethral swabs

For research use only.

For in vitro diagnostic use. Some Pseudomonas may have similar mauve colony aspect and can be eliminated by an oxidase test. Many S. typhi can be detected after 24-48h incubation as mauve variable size colonies. Final identification must be done by biochemistry and serology.

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
Visual chromogenic differentiation and/or selective production of distinctive colony growth with typical identifiable morphology

Key Features

Fully enclosed cassette with air filtration system
Nutritive culture colony growth medium, formulated for selectivity and specificity
Anaerobic or aerobic system available
