LMP-027 Anti-Clostridium difficile activity, drug combination synergetic/additive effect, and tolerant mutant screening and characterization [PDF]

open access: yes, 2017
抗菌药物是对抗细菌感染的有力武器,自第一种抗生素青霉素被发现并应用于临床以来,人类已经开发出多种抗菌药物,然而由于抗菌药物的不合理使用,细菌耐药问题日益严峻,多重耐药菌不断出现,对人类健康构成严重威胁。这需要研发新型抗菌药物用于治疗多耐药细菌引起的感染;然而传统抗菌药物开发耗时长、成本高、风险大,医药公司对此并不热衷,新型抗菌药物上市越来越少。老药新用是抗菌药物开发的新思路,这些药物已经用于临床或正在进行临床试验,安全性评价资料齐全,这大大减少药物开发的成本和风险。过去几十年间 ...

圈养条件下不同年龄孟加拉白虎的肠道菌群研究

open access: yes野生动物学报, 2021
在圈养条件下,为了探知孟加拉白虎(Panthera tigris tigris)的肠道菌群结构以及不同年龄孟加拉白虎的肠道菌群差异,对亚成年和成年孟加拉白虎的粪便菌群进行高通量测序分析。结果表明:在2组白虎的肠道菌群中,放线菌门(Actinobacteria)和厚壁菌门(Firmicutes)最为优势,比例达80%以上;柯林斯菌属(Collinsella)比例最高,平均含量为438%,梭杆菌属(Fusobacterium)、布劳特氏菌属(Blautia)和瘤胃球菌类群(Ruminococcus ...

Molecular diversity of the intestinal bacterial flora in small abalone, Haliotis diversicolor [PDF]

open access: yes, 2010
杂色鲍是我国南方沿海海水养殖的重要经济贝类。肠道菌群在宿主生长发 育、新陈代谢等方面起到重要作用。通过开展杂色鲍肠道菌群多样性的研究,旨 在理解肠道菌群与杂色鲍之间相互关系,包括消化食物、病理发生等,对探讨微 生物与海洋无脊椎动物相互关系具有重要意义。 本文通过微生物分离培养鉴定与不依赖培养的微生物分子生态学方法对不 同养殖环境的杂色鲍肠道菌群的多样性进行研究。从两个养鲍场(江口、大嶝) 杂色鲍肠道内共分离到35株细菌,经16SrRNAgene分子鉴定分属于9个属, 分别为Vibrio ...

肠道菌群变化在2型糖尿病诊疗中的价值

open access: yesZhongguo shiyan zhenduanxue, 2017
1肠道菌群与2型糖尿病人体胃肠道中存在着大量的正常菌群,其肠道内微生物主要由厚壁菌门、拟杆菌门、放线菌门、变形菌门以及疣微球菌门组成,而厚壁菌门及拟杆菌门占优势,某些病毒及真核生物也同时存在于肠道内[3]。肠道菌群和肥胖症的发生有很大的关系,其与2型糖尿病的关系亦是如此,有学者发现,改变肠道菌群构成 ...

饲料和不同生活时期对人工饲养大壁虎肠道菌群的影响

open access: yes野生动物学报, 2022
为了优化人工饲养大壁虎(Gekko gecko)的膳食结构及养殖程序,研究了蝗虫(Locusta migratoria manilensis)、黄粉虫(Tenebrio molitor)、土鳖虫(Eupolyphaga sinensis)及大麦虫(Zophobas morio)4种昆虫饲料对大壁虎生长速度的影响,并通过16S rDNA高通量测序技术比对了大壁虎胃肠道微生物菌群差异及冬眠期与捕食期的大壁虎胃肠道微生物菌群差异。结果表明:饲喂不同昆虫饲料对大壁虎的增重效果不同。单一昆虫饲料组中 ...
