Maior periculi factor propter Clostridium difficile infectionem (CDI) est usus antibioticorum propter distractionem aequilibrii exercitus ventris microbiota.Ad conservandum commodi bacteria insitum probioticae in curatione contagione, usus molecularum cum actione antibacterial selectiva efficaciam auget per C. difficilem selective tollendo.Una earum est planta alkaloidis 8-hydroxyquinolinea (8HQ), quae ostensa est clostridia selective inhibere sine reprimendo bifidobacteria.Actio antimicrobialis selectiva plerumque probatur per culturas technicas singularum modorum bacterialium.Praecipua tamen harum artium limitatio est non posse describere differentialem incrementi dynamicorum magis bacterialium modorum in co-cultura in eodem experimento.In praesenti studio, fluorescentes in situ hybridizationis et cytometriae fluunt, ad describendas mutationes cellularum activarum et non-activarum mixti culturae per opportunisticam pathogen C. diff icile CECT 531 formata et utile Bifidobacterium longum subsp.longum CCMDMND BL1 expositi 8HQ.Observatum est sine 8HQ, utriusque modos proportio fere aequalem esse, oscillantem inter 22,7 et 77,9% in tempore temporis 12 h, cum vero 8HQ proportio activae C. difficilem post 4 h diminutam, perstare tantum inter 8.8. et 17.5%.E contra incrementum bifidobacterial a 8HQ non turbatum est.Eventus huius studii ostendit effectum inhibitorium selectivum 8HQ in dynamicis clostridialibus et bifidobacterialibus incrementis et potentia huius compositi ad progressionem agentium selectivorum ad moderandum CDIs.
