Description

The importance of screening as part of an effective infection control programme to limit the spread of MRSA is well recognized. Speed and accuracy of results are critical aspects of this. Colonized patients must be targeted for isolation and appropriate treatment as early as possible. While negative patients need to be given the all clear to ensuring that valuable infection control resource is not wasted on patients who are not colonized.

Over recent years, the performance of media for MRSA screening has improved dramatically. As part of continuous improvement policy, the work of our team of research and development scientist has led resulted in the development of Brilliance MRSA 2 Agar, which reliably recovers MRSA strains in just 18 hr. The enhanced formulation has greater accuracy than previous formulations1, giving more reliable results. It produces large MRSA colonies than previous formulations, making it easier to work with1. A new chromogenic provides more consistent colony colour, with better differential, so aiding interpretation2.

Brilliance MRSA 2 Agar can be inoculated from a screening swab taken from hospital patient or staff, from an isolated colony or from a liquid suspension. MRSA grows as blue colonies which are very easy to read against the light coloured, opaque background. Plates are incubated at 37ºC, and provide high sensitivity and specificity, with results available in just 18 hours. This allows a rapid response, so enabling the patient to receive the most appropriate treatment as early as possible reducing the risk of onward transmission of infection. Accuracy minimizes costs, by helping to ensure that only those in need receive what can be costly treatment.

Technique

Brilliance MRSA 2 Agar can be inoculated from screening swabs taken from hospital patients or staff, an isolated colony or from liquid suspension, according to local guidelines. The medium should be allowed to warm to room temperature before inoculation. Incubate for 18–24 hr. at 37ºC. There is no need to incubate beyond 24 hr. Denim blue colonies are presumptive positive for MRSA. Identifications as S. aureus can be confirmed with Staphytect Plus (DR0850) or Dryspot Staphytect Plus (DR0100), and PBP2′ (DR0900) can be used to confirm MRSA.
