Abstract
Disclosed are compositions, methods and systems for detecting MRSA, for example MRSA nasal colonization. In certain embodiments, the methods use bacteriophage-based amplification of the signal in detection of bacteria and other microorganisms to detect MRSA. The methods for detecting MRSA may include preparing an assay comprising a selective agent and a cocktail comprising at least two different types of recombinant bacteriophages, incubating the sample in the assay, capturing an indicator protein product, and detecting an indicator protein product produced by the recombinant bacteriophage, wherein positive detection of the indicator protein product indicates that MRSA is present in the sample.
