Fig 6. Growth of S. maltophilia BurA1 and BurA1ΔebyCAB expressed in number of copies of bacterial smeD gene per mL, in co-culture with amoeba and confocal microscopy.

(a) co-culture with A. castellanii L6a; (b) co-culture with W. magna C2c. Means +/- standard deviations from three independent experiments in duplicate are presented; (c) Fluorescent confocal microscopy images of A. castellanii in co-culture with S. maltophilia BurA1ΔebyCAB after 48 hours; (d) Fluorescent confocal microscopy images of W. magna in co-culture with S. maltophilia BurA1ΔebyCAB after 48 hours.
