Table 4 No. of CoNS isolates showing reductiona or enhancement when biofilms/adherent cells exposed to antibiotics.

From: Antibiotic susceptibility of coagulase-negative staphylococci isolated from very low birth weight babies: comprehensive comparisons of bacteria at different stages of biofilm formation

Effect Number (%) of isolates affected by
  Gentamicin (GEN) Oxacillin (OXA) Vancomycin (VAN) GEN, OXA, VAN
Reduction 2 (8) 7 (29) 14 (64) 14 (64)
Enhancement 0 (0) 2 (8) 0 (0) 0 (0)
None 22 (92) 15 (63) 10 (36) 10 (36)
  1. a After overnight antibiotic exposure, the difference in OD600 values between test biofilms and antibiotic-free wells, if greater than intra-microplate variability, were defined as significant; a decrease was considered a reduction and an increase was considered an enhancement.
