It reviews detection methods including traditional culturing, PCR for rapid but contamination-sensitive results, and longer immunoassays. A new rapid biosensor, CANARY, is introduced, which uses genetically engineered B lymphocytes to detect antigens, emitting light when specific antigens are present. This method is noted for its high sensitivity, specificity, and speed.
