    Notes: Abstract The effect on the faecal aerobic and anaerobic flora of ciprofloxacin given in low doses for selective decontamination of the digestive tract was investigated in ten human volunteers. The volunteers received 50, 100 and 200 mg of ciprofloxacin every 12 h for five days at intervals of three and five weeks respectively. No significant differences in the numbers of aerobes or anaerobes were seen after the 2 × 50 mg regime. The colony counts of most anaerobes and the total aerobe count were significantly decreased after the 2 × 200 mg regime. Whereas the aerobe count was also significantly decreased after administration of 2 × 200 mg, the anaerobe count remained stable.Clostridium difficile was not detected during or after treatment. From these results it can be concluded that ciprofloxacin in a dose of 2 × 100 mg can be recommended for selective decontamination of the digestive tract.

    Description / Table of Contents: Zusammenfassung Der Einfluß von FCE 22891 auf die Fäkalflora wurde bei 11 Patienten mit akuter Exazerbation einer chronisch obstruktiven Lungenkrankheit im Vergleich zu gesunden freiwilligen Probanden untersucht. In frischen Stuhlproben, die vor, während und nach Gabe des Antibiotikums gewonnen wurden, wurden die Koloniebildnerzahlen der aeroben und anaeroben Keime und die Konzentrationen kurzkettiger Fettsäuren und organischer Säuren gemessen. Für die 142 Anaerobier-Isolate wurden die MHK-Werte von FCE 22891 bestimmt und mit den biologisch aktiven Konzentrationen der Substanz im Stuhl verglichen. Am Tag 9 waren die Koloniebildnerzahlen vonBacteroides bei den Patienten signifikant höher als am Tag 3, sie lagen jedoch signifikant unter den Werten bei gesunden Probanden vor, während und nach Gabe der Testsubstanz. Während und nach der Therapie kam es zu signifikanten Änderungen der Konzentration kurzkettiger Fettsäuren und organischer Säuren; die Unterschiede waren vor allem im Vergleich zu den gesunden Probanden sehr ausgeprägt. BeiClostridium-Spezies außerClostridium difficile war ein ausgeprägter Anstieg der MHK-Werte von FCE 22891 unter der Therapie festzustellen. FCE 22891 hatte nur mäßig ausgeprägten Einfluß auf die anaerobe Stuhlflora. Die Bakterienfermentation war jedoch vor allem vor und in den ersten Tagen der Behandlung gestört, möglicherweise bedingt durch die Krankheit.
    Notes: Summary The influence of FCE 22891 on the faecal flora was investigated in 11 patients with an acute exacerbation of chronic obstructive pulmonary disease (COPD). Colony counts of faecal (an)aerobes and concentrations of their short-chain fatty acids and organic acids were determined simultaneously in fresh faeces before, during and after administration of the drug, and compared to those of healthy human volunteers. The MIC of FCE 22891 for the 142 isolated anaerobes was determined, and compared to the biologically active concentration of the drug in faeces. TheBacteroides colony counts of the patients increased significantly by day 9 compared to day 3, but were significantly lower than those of the healthy controls before, during and after the study. Significant changes in short-chain fatty acids and organic acid concentrations occurred in faeces of the patients during and after treatment, and especially when compared to healthy controls. A strong increase in MICs during treatment was found inClostridium species, other thanClostridium difficile. FCE 22891 had only a moderate effect on the composition of the anaerobic faecal flora, but bacterial fermentation was mainly disturbed before and early on in treatment, which could have been caused by the disease.
