摘要:
Disclosed herein are methods and systems for detection of a microorganism of interest using an amplification assay. The methods and systems utilize the specificity of binding agents, such as antibodies, to rapidly detect low levels of a specific microorganism present in a sample. In certain embodiments, antibodies are bound to a large number of the available binding sites on a microorganism.
摘要:
Disclosed herein are methods and systems for rapid detection of microorganisms in a sample, without culturing for enrichment of the microorganism. A modified bacteriophage is also disclosed which comprises a non-native indicator gene in the late gene region. The indicator product is not a fusion protein. The specificity of infectious agents allows a specific microorganism to be targeted, and an indicator signal may be amplified to optimize assay sensitivity.
摘要:
Disclosed are methods and systems for the isolation and detection of microbes from a sample. The use of binding agents for isolation of a microbe of interest from a sample are described. In certain embodiments, the methods use ribosome-based and/or bacteriophage-based amplification of the signal in detection of bacteria and other microorganisms. For example, embodiments of the present invention can achieve total amplification of at least 10,000 from a single infected cell.
