小鼠盲肠内容物中正常菌群的分离和定量 总被引:1,自引:0,他引:1
本文报道了采用厌氧培养技术,从小鼠盲肠内容物中分离到6株严格厌氧和兼性厌氧菌。鉴定为拟杆菌、乳酸杆菌、双歧杆菌、难辨梭菌、粪链球菌和大肠扦菌。它们在小鼠盲肠内容物的正常菌群中占优势,含菌量与国外文献中报告的相似。 相似文献

Three strains of B. thetaiotaomicron have been isolated from caeca of BALB/c-nu/+ mice of SPF. These Bacteroides are obligately anaerobic, Gram-negative, non-spore-forming and non-motil without flagella rods. A characteristic of staining is deep at ends and stainless at the medium of a rod. The isolation and identification of these strains has been reported in 1987. This paper introduced only the results of EM observations. Under the SEM, the unstained area of rods is always showing a concavity, which is just a nucleoid in sections under the TEM. Many lamellar corpuscles have been found in cell plasma. Some of them have been secreted out of the cells. The chemical properties and physiological functions of them are unknown. 相似文献

黑线姬鼠的人工繁殖与驯化 总被引:1,自引:0,他引:1
野生黑线姬鼠是一种良好的EHF病毒动物模型。国内外未见有人工饲养繁殖和驯化方面的报道。我们从1983年起,对野外捕获的6只黑线姬鼠(雌雄各半),在常规饲养室条件下进行人工饲养繁殖和驯化的研究,取得了初步结果。现报告如下。 相似文献
