phAE87Δ17mt3 is viable but has shorter tails that its parent phage. Electron micrographs of representative particles of phAE87 (A) and phAE87Δ17mt3 (B). The average tail length is 200 ± 10 nm for phAE87 and 180 ± 6 for phAE87Δ17mt3. The tail lengths of 30 individual phage particles for each phage were measured.
