Figure 5. B. cenocepacia infection of duckweed is alleviated by bacteriophage treatment up to 12 h but not after 18 h.

A. B. cenocepacia K56-2 was inoculated into plant-containing wells at 2x10⁶ cfu/ml, with 4x10⁸ pfu/ml of phage KS12 (i.e. MOI = 200) applied at 0, 6, 12, 18, and 24 h. Results shown are averages of 3 independent trials using 6 plants per trial +/- SE. “Untreated” refers to both phage-treated and mock-treated plants, as both showed 100% survival. B. Bacterial counts from media surrounding plants during the infections (not phage-treated). Results shown are averages of 3 independent trials performed in triplicate +/- SE. C. Bacterial counts from crushed surface-sterilized plants. Results shown are averages of 3 independent trials +/- SE, with four replicates of each sample per trial.
