Zhongguo shiyan zhenduanxue, 2022 微生物组成差异较大,胃肠道的微生物数量约为1012-1014个,人体自身细胞的数量仅为其1/10。现阶段研究已发现从食管至直肠,微生物丰度和多样性呈现递增趋势。胃微生物区系与口腔、食管和十二指肠的微生物区系的构成极为相似,而与结肠却有很大差异。尽管胃中可培养细菌的丰度只有102-104个菌落形成单位(CFU)/ml,明显低于结肠中1010-1012 CFU/ml,但胃内微环境的稳态及微生物菌群的变化在胃部疾病中的作用至关重要。本文就近年来微生物菌群包括幽门螺杆菌及其他微生物感染与胃溃疡的关系 ...

野生动物学报, 2021 在青海高原，国家二级保护鸟种，高山兀鹫（Gyps himalayensis）以动物和人类的尸体为食，对维持生态系统平衡至关重要。然而，腐尸中存在诸多有害因素（如兽药残留，病原菌或病毒感染等），对高山兀鹫种群的生存和保护构成威胁。肠道微生物调控宿主的免疫、营养物质代谢及发育等诸多生理过程，因此，也成为野生动物保护领域的研究热点。为了解高山兀鹫肠道微生物的多样性及其耐药情况，本研究采集野生高山兀鹫的新鲜粪便在实验室进行细菌分离培养、16S rRNA基因PCR扩增和序列分析、生化鉴定以及细菌耐药性试验 ...

Advances in the Structure, Separation, Bioactivities and Applications of Probiotic Extracellular Vesicles [PDF]
Extracellular vesicles (EVs), emerging as a novel category of postbiotics, possess various bioactive functions. Probiotic-derived EVs are nanoscale lipid bilayer particles secreted by probiotics into the extracellular matrix, which cannot self-replicate.
