细菌群体

In two NIH-funded studies published this week in the journal Nature, the scientists report that the relative abundance or ratio of two of the most common groups of gut bacteria is altered in both obese humans and mice.

在两个全国卫生研究所资助的研究报告发表在本周的Nature杂志上，科学家报告说，相对丰度或比例的两种最常见的群体的肠道细菌是变造的，在双方肥胖人类和老鼠。

The biological analysis results showed: Population Doubling Time of cells was approximately 24 h;Diploid account for 76%～88% in cell's chromosome;By Isozyme analysis of Lactic Dehydrogenase,Malic Dehydrogenase,cross contamination had not taken place;The test results of ...

结果表明：细胞群体倍增时间约为24 h；细胞染色体中二倍体(2n=60)占主体，镜检细胞的百分比为98.2%；乳酸脱氢酶、苹果酸脱氢酶同工酶分析，没有其他物种污染；细菌、真菌、病毒、支原体检测阴性。

Few creatures—even bacteria—do without sex entirely, but bdelloid rotifers are among that minority.

很少有生物是完全的无性繁殖，连细菌也不是，但蛭形轮虫却属于这个少数群体。

In this work, we isolated 47 strains of actinomycetes from the mud sample of Jiaozhou Bay. Quorum sensing inhibitory activity was monitored by Chromobacterium violaceum CV026. As a result, the culture broth extract of actinomycetes WA-7 was found to have significant quorum sensing inhibitory activity. This strain was assigned to the genus Streptomyces based on its 16S rDNA sequence.

我们从胶州湾海泥中分离得到放线菌47株，其发酵提取物经紫色杆菌CV026模型筛选后，发现放线菌WA-7提取物具有群体感应抑制活性，且在有效浓度时对细菌的生长没有影响。16S rDNA分析表明WA-7应属于Streptomyces属。

Quorum sensing is an environmental-signal-sensing system in bacteria. It is relies upon the interaction of a diffusible signal molecule with cell population density.

群体感应是细菌检测自身群体密度大小的环境信号感受系统，在细菌细胞间信息交流中具有极其重要的作用。

Many pathogens of animal and plant, such as Erwinia cawtovora pv.carotovora and Pseudomonas aeruginosa, producing some kinds of virulence factors before attacking the host, and most of those virulence factors was modulated by the quorum-sensing system which relys on the secret of some small quorum sensing signals.

很多动植物的病原细菌，包括胡萝卜软腐欧文氏菌和铜绿假单胞菌等在侵染动植物有机体的过程中，首先利用细菌的群体感应机制诱导致病因子的表达，在致病因子的作用下侵染宿主。

Objective: To observe the self-regulation of wave growth of Proteus mirabilis (P. mirabilis) and to explore the role of the regulative factors of bacterial biowaves in self-arrangement of a group of cells.

目的：探讨群体细菌波动生长的自组织特征，认识生物波调控因子在群体细胞的自组织过程中的作用。

Such techniques can yield complex community profiles and can also provide useful phylogenetic information.

这种技术也可以很快的报告这些群体的分布也可以提供这些细菌群体的形态上的信息。

And each of us harbors a microbial mix that's a bit different from our neighbors'.

而我们每个人身上的细菌群体都与其它人不同。

The quorum sensing commonly exists in procaryote kingdom, regulating various biologic functions.

群体感应现象在细菌中普遍存在，参与细菌多种生理功能的调控。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
