  1. a Average results of densitometric analysis of three independent fluorograms.
  2. b Values were normalized to the band intensity of PBP2 from L. monocytogenes pAKB, which was assigned the value of 1.
  3. c Indicates band with intensity significantly different (P < 0.05; acc. to Student's t-test) from the corresponding band of the control strain.
