Aztreonam, temocillin, gentamicin and tobramycin were studied for their effect on the human faecal flora in vitro and for their usefulness for selective decontamination (SD) of the gastrointestinal tract. The sensitivities of the obligately anaerobic flora and the Gram-negative facultatively anaerobic bacteria were determined and the ratio was expressed as SD factor. The high SD factor of the flora from most subjects for aztreonam and tobramycin indicates that the drugs are useful for SD in contrast to temocillin and gentamicin. Binding to and subsequent release of tobramycin from faeces are presumed to facilitate the maintenance of adequate concentrations in the intestine despite the discontinuous intake.
研究了氨曲南、替莫西林、庆大霉素和妥布霉素对人体粪便菌群的体外作用及其在胃肠道选择性去污(SD)中的效用。测定了专性厌氧菌和革兰氏阴性兼性厌氧菌的敏感性,并将该比值表示为SD因子。大多数受试者粪便菌群对氨曲南和妥布霉素的高SD因子表明,与替莫西林和庆大霉素相比,这些药物对SD有用。据推测,妥布霉素与粪便的结合及随后从粪便中的释放有助于在不连续给药的情况下维持肠道中的足够浓度。
