The fluorescence intensity of membrane-bound N-phenyl-1-naphthylamine increases dramatically when T5 bacteriophage infect colicin Ib plasmid-containing hosts. This dramatic increase is not seen during normal infections or in infections wherein either the plasmid or the phage contain mutations which allow productive infection to occur. Two smaller increases in fluorescence intensity are seen, however, in all T5 infections in which the characteristic two-step injection of DNA can proceed.
