摘要:背景:肠易激综合征(IBS)是影响患者生活方式的常见疾病。它与肠道微生物组组成的显着变化有关,但是潜在的微生物机制仍有待完全了解。我们研究了便秘的IBS(IBS-C)和混合型IBS(IBS-M)患者的粪便微生物组。方法:我们在离子Torrent PGM测序平台上对16S rRNA的V3区进行了测序,以研究微生物组。结果:与健康组相比,在IBS-C和IBS-M患者中,发现α多样性的增加,并且还指出了β多样性的差异。在门水平上,两种IBS亚型均显示出企业/杀菌素比的增加,并且肌动杆菌和verrucomicrobobiota的丰度增加。Changes in some types of bacteria were characteristic of only one of the IBS subtypes, while no statistically significant differences in the composition of the microbiome were detected between IBS-C and IBS- M. Conclusions: This study was the first to demonstrate the association of Turicibacter sanguinis , Mitsuokella jalaludinii , Erysipelotrichaceae UCG-003 ,塞内加马群岛厌氧菌,Corynebacterium jeikeium,Bacteroides Faecichinchillae,Leuconostoc carnosum和parabacteroides Merdae具有IBS亚型。
