Enzyme-Linked Phage Receptor Binding Protein Assays (ELPRA) Enable Identification of Colonies.

Bacteriophage receptor binding proteins (RBPs) are employed by viruses to recognize specific surface structures on bacterial host cells. Recombinant RBPs have been utilized for detection of several pathogens, typically as fusions with reporter enzymes or fluorescent proteins. Identification of , the etiological agent of anthrax, can be difficult because of the bacterium's close relationship with other species of the group.
