Chromogenic differentiated results for surveillance and environmental testing.

Over recent years, the occurrence of hospital infections caused by methicillin resistant Staphylococcus aureus (MRSA) has been increasing steadily, representing around 20 to 55% of the isolates in Europe and in the USA. Leading cause of nosocomial infections, especially in intensive care units, the MRSA sources are either endogenous (the patient) or through cross contamination (environmental or by person to person contact). The major issue with this pathogen is its resistance to a large panel of antibiotics, among them beta-lactam antibiotics, limiting the therapeutic options for clinicians.

InTray COLOREX MRSA provides an easy-to-use, in-house, chromogenic result for surface testing and AMR surveillance.


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

Inhibit the growth of yeasts, mold, and fungi, resulting in 91.5% specificity for the growth of Oxacillin strains.
