Abstract: Several peptides for selectively and specifically binding Bacillus anthracis spores are disclosed herein. It is contemplated that the isolated peptides will be incorporated into diagnostic probes. The diagnostic probes may include landscape page probes and antibody probes, as well as any other probes known in the art. Inventors contemplate that the probes could be further used in real-time continuous monitoring of the environment so that detection systems for monitoring the low concentrations of Bacillus anthracis spores may be developed.
