Abstract
Chlorhexidine is a clinically important antiseptic, disinfectant and preservative. It is a potent membrane-active agent against bacteria and inhibits outgrowth, but not germination, of bacterial spores, although it is not sporicidal. It shows high activity against wild-type and outer membrane mutants ofEscherichia coli but some gram-negative bacteria are resistant to chlorhexidine by mechanisms not yet fully understood, although they appear to involve the outer, rather than the inner, membrane. Chlorhexidin hat als Antiseptikum, Desinfiziens und Konservierungsmittel große klinische Bedeutung. Chlorhexidin ist als membranaktive Substanz hochwirksam gegen Bakterien und hemmt die Vermehrung, aber nicht das Aussprossen von Bakteriensporen, obwohl es keine sporizide Substanz ist. Gegen den Wildtyp und andere Membranvarianten vonEscherichia coli ist Chlorhexidin hochwirksam; einige gramnegative Bakterien sind jedoch gegen Chlorhexidin resistent; die dafür verantwortlichen Mechanismen sind noch nicht voll aufgeklärt, doch scheint es, daß eher die äußere als die innere Membran betroffen ist.Keywords
