Abstract
This invention provides safe, non-infectious chimeras that include the nucleic acid signature of most bacterial and viral biological threat agents. These chimeras mimic properties of threat agents and are useful as simulants to develop, evaluate, test, and train on nucleic acid-based biodetectors and diagnostic products of interest in biodefense, without the need for accessing or producing virulent agents.
Claims3
A method of detecting a biological threat agent, comprising the steps of:
- (a) providing one or more samples suspected of containing one or more biological threat agents;
- (b) performing a nucleic-acid based detection method to detect said one or more biological threat agents in said one or more samples;
- (c) providing an additional sample containing a chimera comprising a plurality of segments, wherein each segment uniquely corresponds to a portion of the genome of a biological threat agent whose genome is DNA, and wherein said plurality of segments comprises a nucleic acid sequence comprising SEQ ID NO:
- 12;
- and
- (d) performing said nucleic-acid based detection method to detect said chimera in said additional sample as a positive control.
