A Kirby-Bauer disk sensitivity plate was prepared and zones of inhibition formed around 4 of the disks.  These zones were subcultured onto a new plate by using a needle to touch along a line from the edge of the disk to the edge of the zone.  The results are shown on in the image below.  (The first inoculation from the edge of the disk is on the right side.)  Which antibiotic(s) had some bacteriocidal effect on the organism?
