The Influence of Subinhibitory Concentrations of Antibiotics on the Bacterial Surface with Respect to Host Defense Mechanisms
It is well known that a successful treatment of bacterial infections depends on an effective host defense system. This observation presupposes either that the antibiotic treatment reduces the number of bacteria in a given infection and that the remaining bacteria are subsequently eliminated by the host-defense system, or that antibiotics render bacteria more susceptible to host defense mechanisms. In addition, it is well established that β-lactam antibiotics interfere with peptidoglycan synthesis and that this is combined with changes in the shape of bacteria. Several authors (2,3,12) have pointed out that there is a mutual influence between peptidoglycan and membrane synthesis, but the arrangement and composition of the outer membrane under the influence of (β-lactam antibiotics have so far not been investigated adequately.
