Inhibition of λcI72 vegetative growth on dnaB-grpD55 host.

Host strains	EOP on host cells incubated at temperature a
	30	37	39	42 ˚C
594	1.0	ndb	nd	0.94
594 grpD55	0.0147	4.4 × 10-7	4.4 × 10-7	4.6 × 10-7

^a: Efficiency of plating (EOP) of λcI72 was determined by dividing the average phage titer on 594 dnaB-grpD55 host cells by the titer on 594 host at 30 ˚C (= 6.8 × 10⁹ pfu/ml).

^b: nd = not determined.
