Background Numerous studies have thus far characterized the temporal dynamics of the skin
microbiota of healthy individuals. However, there is no information regarding the dynamics …

We present a global atlas of 4,728 metagenomic samples from mass-transit systems in 60
cities over 3 years, representing the first systematic, worldwide catalog of the urban microbial …

Background Pathogenic and allergenic bacteria and fungi within the indoors can bring
detrimental health effects on the occupants. We previously studied the bacterial communities …

Background Polycyclic aromatic hydrocarbons (PAHs) are of environmental and public
health concerns and contribute to adverse skin attributes such as premature skin aging and …

Studies of the indoor airborne microbiome have mostly been confined to a single location
and time point. Here, we characterized, over the course of a year, the geographic variation, …

The importance of microorganisms to human skin health has led to a growing interest in the
temporal stability of skin microbiota. Here we investigated the dynamics and assembly of …

The dispersion of microorganisms through the atmosphere is a continual and essential
process that underpins biogeography and ecosystem development and function. Despite the …

Background The human skin microbiome has been recently investigated as a potential
forensic tool, as people leave traces of their potentially unique microbiomes on objects and …

Although studies have shown that urban environments and mass-transit systems have
distinct genetic profiles, there are no systematic worldwide studies of these dense, human …

Viruses in built environments (BEs) raise public health concerns, yet they are generally less
studied than bacteria. To better understand viral dynamics in BEs, this study assesses …
