概括

孕产妇的B组链球菌 (GBS) 殖民与特定的病原体有关,而不是整体的阴道微生物组变化. 这些微生物可以作为不良妊娠结果的临床标志.

科学领域:

微生物学微生物学
产科产科产科产科产科
基因组学就是基因组学.

背景情况:

乙组链球菌 (GBS) 殖民和阴道微生物组 (VMB) 失调与不良周围生育结果有关.
GBS殖民对母体VMB的特定影响仍然在很大程度上没有特征.

研究的目的:

调查GBS殖民和母体VMB之间的关系.
为了确定与GBS殖民相关的额外病原体,以获得潜在的临床意义.

主要方法:

来自孕妇的阴道样本使用16S rRNA基因测序来分析GBS和VMB组成.
多样性分析和社区状态类型聚类比较了GBS阳性和负组.
ANCOM-BC确定了与GBS殖民相关的差异丰富的微生物 (DAMs).

主要成果:

在整体VMB多样性或社区状态类型中,在GBS阳性和负组之间没有观察到显著的差异.
四种DAMs (Actinomyces,Shigella,Fenollaria,Gemella) 与GBS殖民有显著的关联. 这四种DAMs (Actinomyces,Shigella,Fenollaria,Gemella) 与GBS殖民有显著的联系.
这些DAM与出生体重有负相关性,并显示出预测早产膜破裂的潜力.

结论:

母亲GBS殖民与特定的病原体有关,而不是广泛的VMB变化.
这些已识别的病原体可能起到微生物特征的作用,在怀孕期间具有临床效用.

Anatomy of the Intestines

Anatomy of the Intestines

Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

Surface Membrane Barriers

Surface Membrane Barriers

The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

Bacterial Phylum Verrucomicrobiota

Bacterial Phylum Verrucomicrobiota

The phylum Verrucomicrobiota comprises at least four characterized orders, with most species classified within the order Verrucomicrobiotales. Members of this phylum are either aerobic or facultatively aerobic, with the ability to ferment sugars. A notable exception is the genus Methylacidiphilum, which consists of aerobic methanotrophs. Additionally, some Verrucomicrobiota establish symbiotic relationships with protists. These bacteria are widely distributed across various environments,...
