| 摘要 |
Compositions and methods for in situ detection of one or more target microorganisms on a surface and preferably on a hard surface. Compositions and methods of the invention are based on the specificity of certain bacteriophage for target microorganisms. Bacteriophage are modified to express detectable biomarkers in the presence of the target microorganism, the detectable markers being detectable on the surface being tested using a portable detection device. Only living microorganisms are detected using the methods and compositions of the invention.
