Abstract:
:To clarify the cause of the supersusceptibility of Branhamella catarrhalis to macrolide antibiotics, which are well-known to be inactive to most Gram-negative bacteria, we determined its cell surface hydrophobicity by the partition experiment between water and hydrocarbons. Its cell surface was found to be markedly more hydrophobic than that of Escherichia coli or Pseudomonas aeruginosa cells. This suggested that the outer membrane of B. catarrhalis plays no role as a diffusion barrier towards hydrophobic agents.
