Khatarta ugu weyn ee caabuqa Clostridium difficile (CDI) waa isticmaalka antibiyootiga taas oo ay ugu wacan tahay carqaladaynta dheellitirka microbiota xiidmaha martida loo yahay.Si loo ilaaliyo bakteeriyada deegaanka ee faa'iido u leh inta lagu jiro daawaynta caabuqa, isticmaalka molecules oo leh firfircoonida bakteeriyada xulashada waxay kor u qaadaysaa waxtarka iyada oo si xushmad leh looga saarayo C. difficile.Mid ka mid ah iyaga ka mid ah waa alkaloid geedka 8-hydroxyquinoline (8HQ), kaas oo la muujiyay in ay si xushmad leh u joojiso clostridia iyada oo aan la cadaadin bifidobacteria.Dhaqdhaqaaqa antimicrobial ee xulashada ah waxaa guud ahaan lagu tijaabiyaa farsamooyinka dhaqameed ee noocyada bakteeriyada gaarka ah.Si kastaba ha ahaatee, xaddidaadda ugu weyn ee farsamooyinkan ayaa ah awood la'aanta in lagu qeexo dhaqdhaqaaqa koritaanka kala duwan ee noocyada bakteeriyada badan ee dhaqanka isla tijaabada isku mid ah.Daraasadda hadda jirta, waxaan isku darnay fluorescent in situ hybridization iyo qulqulka cytometry si aan u sharaxno isbeddelada unugyada firfircoon iyo kuwa aan firfircoonayn ee dhaqanka isku dhafan ee ay sameeyeen pathogen-ka fursada C. diff iile CECT 531 iyo faa'iidada Bifidobacterium longum subsp.longum CCMDMND BL1 ka dib soo-gaadhista 8HQ.Waxaa la arkay in 8HQ la'aanteed, saamiga labada noocba ay ahaayeen kuwo siman, oo u dhexeeya 22.7 iyo 77.9 % inta lagu jiro wakhtiga 12 h, halka 8HQ saamiga firfircoon ee C. difficile uu hoos u dhacay 4 saacadood ka dib, wuxuuna socday oo kaliya inta u dhaxaysa 8.8 iyo 17.5 %.Taas bedelkeeda, korriinka bifidobacteria laguma dhibin 8HQ.Natiijooyinka daraasaddan ayaa muujisay saameynta xakamaynta xulashada ee 8HQ ee dhaqdhaqaaqa koritaanka clostridial iyo bifidobacterial, iyo awoodda xaruntan ee horumarinta wakiilada xulashada si loo xakameeyo CDI.
