Eyona nto iphambili esemngciphekweni wosulelo lweClostridium difficile (CDI) kukusetyenziswa kwamayeza okubulala iintsholongwane ngenxa yokuphazamiseka kokulingana kwe-host gut microbiota.Ukugcina iibhaktheriya ezixhamlayo zokuhlala ngexesha lokunyanga ukusuleleka, ukusetyenziswa kweeamolekyu ezinomsebenzi okhethiweyo we-antibacterial kuphucula ukusebenza ngokukhetha ngokususa i-C. difficile.Enye yazo isityalo i-alkaloid 8-hydroxyquinoline (8HQ), eye yaboniswa ukuba inqande i-clostridia ngaphandle kokucinezela i-bifidobacteria.Umsebenzi okhethiweyo we-antimicrobial uvavanywa ngokubanzi ngobuchule benkcubeko yohlobo lwebhaktiriya nganye.Nangona kunjalo, owona mda uphambili wobu buchule kukungakwazi ukuchaza amandla okukhula okwahlukileyo kwiintlobo ezininzi zebhaktheriya kwinkcubeko edibeneyo ngaphakathi kovavanyo olufanayo.Kuphononongo lwangoku, sidibanise i-fluorescent in situ hybridization kunye ne-cytometry yokuhamba ukuchaza utshintsho kwiiseli ezisebenzayo kunye nezingasebenziyo zenkcubeko edibeneyo eyenziwa yi-opportunistic pathogen C. diff icile CECT 531 kunye ne-Bifidobacterium longum subsp enenzuzo.longum CCMDMND BL1 emva kokuba sesichengeni 8HQ.Kwaphawulwa ukuba ngaphandle kwe-8HQ, umlinganiselo weentlobo zombini wawuphantse ulingane, u-oscillating phakathi kwe-22.7 kunye ne-77.9% ngexesha lokuhamba kwexesha le-12 h, kanti nge-8HQ inxalenye ye-C. difficile esebenzayo yehla emva kwe-4 h, kwaye iqhubekile phakathi kwe-8.8 kuphela. kunye ne-17.5%.Ngokwahlukileyo, ukukhula kwe-bifidobacteria akuzange kuphazanyiswe yi-8HQ.Iziphumo zolu pho nonongo zibonise umphumo okhethiweyo we-inhibitory we-8HQ kwi-clostridial kunye ne-bifidobacterial ukukhula kwe-dynamics, kunye nokukwazi kwesi sixhobo sokuphuhliswa kwee-agent ezikhethiweyo zokulawula ii-CDIs.
