概括

室内真菌群落在挪威的家庭和托儿所之间有所不同. 托儿所显示出更多的酵母真菌,而家庭则有更多的模具,可能是由于居住者密度和年龄.

科学领域:

环境科学环境科学
微生物学微生物学
室内空气质量室内空气质量

背景情况:

人们在室内花费大量时间,室内真菌 (mycobiomes) 可以影响健康.
根据建筑物使用情况,了解室内真菌生物群的差异对于公共卫生至关重要.

研究的目的:

为了比较挪威儿童日托中心和私人家庭的室内真菌群体.
调查影响室内真菌生物组合的因素.

主要方法:

从尘埃样本中对真菌群落的DNA元编码.
挪威123个托儿所和214个家庭中的真菌生物组的比较.
与建筑物占用率和年龄分布的相关性分析.

主要成果:

菌类丰富程度相似,但社区组成在托儿所和家庭之间有显著差异.
日间托儿所的酵母真菌 (Saccharomycetales,Filobasidiales,Tremellales) 的相对丰度较高.
房屋显示有线性真菌的相对丰富性更高 (例如,阿斯伯吉勒斯,尼西,克拉多斯波里亚).
托儿所住户密度较高与真菌群体组成的变化相关.

结论:

建筑物的使用,特别是日托和家庭环境,导致不同的室内真菌生物群.
居住者密度和年龄分布是这些观察到的真菌差异的假设驱动因素.
调查结果强调了需要量身定制的策略来管理不同环境中的室内真菌暴露.

Yeast Signaling

Yeast Signaling

Yeasts are single-celled organisms, but unlike bacteria, they are eukaryotes (cells with a nucleus). Cell signaling in yeast is similar to signaling in other eukaryotic cells. A ligand, such as a protein or a small molecule released from a yeast cell, attaches to a receptor on the cell surface. The binding stimulates second-messenger kinases to activate or inactivate transcription factors that further regulate gene expression. Many of the yeast intracellular signaling cascades have similar...
