Killing of A. pleuropneumoniae biofilms by ampicillin. Biofilms were grown for 18 h in MHB and then for 4 additional h in MHB with 0, 10 or 100 μg/ml of ampicillin and 0 or 20 μg/ml of dispersin B. CFUs were determined by dilution plating. Values indicate the mean number of CFUs/tube. Error bars indicate range.
