Activity against various species was assayed in Tryptone Soya Sloppy Agar (TSSB) or Yeast Extract Peptone Sloppy Agar for Candida albicans, produced using the same method as described above (Mann andMarkham,1998). Broth dilutions were executed in 96-well plates using tetracycline as the positive control for bacterial species and nystatin for Candida albicans.
