Fig. 1From: Design and engineering of a transmissible antiviral defenseProtection against T5 infection provided by the phagemid-encoded Targetron. Cells were infected by the ampicillin-resistant phagemid (vaccine) at an MOI of 1.0 (phagemid stock also contained a low concentration of helper phage at MOI 0.01) and grown for the time indicated. They were plated separately on ampicillin and on a high density of T5. The log10 proportion of ampicillin-resistant cells that are T5-resistant is shown. Resistance levels are never more than 1 % and often not more than 0.1 %, even after 8 h. Colors indicate replicates; only one sample was assayed at 8 hBack to article page
