Outdoors, occupants, and the pan-microbiome: a review

Our group here at the City University of Hong Kong is interested in looking at microbial communities in built environments (BEs) of various sorts, including subways and residences.

Microbial Effects on Asthma

Two reviews came out recently by Mutius et al and Smits et al discussing the link between microbes and asthma. Sadly, they are not open access. Both reviews suggest that exposure to microbially rich environments helps build the immune response and inflammation systems. The Mutius et al paper drew from research conducted on urban environmental microbiology using DNA fingerprinting to characterize indoor …
