  1. * Clinical isolates
  2. The antimicrobial activity of Ulmo honey in comparison to manuka honey against five MRSA strains, E. coli and Pseudomonas aeruginosa, assessed by agar well diffusion assay (n = 3). Where no value is given, no zone of inhibition was observed.
  3. Standard deviation values (±) are in brackets
