a
Suspensions of bacteria (106CFU/ml) were spread on Mueller-Hinton agar plates. Bismuth nitrate and BAL were used to impregnate paper disks on the agar surface. The plates were incubated overnight at 37°C, and the zones of inhibition were measured the following day. The data are expressed as the mean for all isolates within a group, along with the standard deviation.
