Table 15.1 shows some practical examples of adequate chronic antibiotic suppression for some specific microorganisms. Of course, the possibilities of potential infectious agents and treatments are very much wider.
Another controversial aspect of antibiotic suppression is the length of treatment. Some authors did not include patients treated with less than 6 months of antibiotic suppression [1, 4–6]. Therefore, we must ensure that antibiotic suppression for patients that are not able to undergo surgery will last as long as the life of patients [1–7].
