Abstract
The intestinal flora was studied in 12 volunteers after the administration of 400 mg ciprofloxacin b.i.d. over seven days. Stool samples were taken prior to and several times after the initiation of therapy, and qualitative and quantitative analyses of microorganisms were performed.Escherichia coli was eliminated in all volunteers after two days of treatment. A selection of resistant enterobacteria could not be observed. A higher incidence ofStreptococcus faecium was seen, mainly after the end of drug application. The number of cfu ofBacteroides andBifidus species remained unchanged during the trial. There was no selection ofClostridium difficile. Based on this pattern of activity on the stool flora we suggest that ciprofloxacin could represent an appropriate drug for the therapy of bacterial intestinal infections as well as for selective decontamination in immunosuppressed patients. Bei 12 Probanden wurden die Veränderungen der Darmflora unter einer siebentägigen Gabe von 2 × 400 mg Ciprofloxacin oral geprüft. Stuhlproben wurden vor und mehrfach nach Therapiebeginn auf Darmbakterien qualitativ und quantitativ untersucht.Escherichia coli war bei allen Probanden nach zwei Tagen eliminiert. Eine Selektion resistenter Enterobakterien wurde nicht beobachtet. Eine höhere Inzidenz vonStreptococcus faecium wurde insbesondere nach Abschluß der Ciprofloxacin-Gabe festgestellt. Die Keimzahlen derBacteroides-undBifidus-Gruppe blieben unter der Therapie unverändert.Clostridium difficile wurde nicht selektiert. Aufgrund des Aktivitätsmusters auf die Darmflora erscheint uns Ciprofloxacin sowohl für die Therapie bakterieller Darminfektionen als auch für die selektive Darmdekontamination immunsupprimierter Patienten geeignet.Keywords
