TL;DR: Both early-life microbial exposure levels and exposure determinants differ across cohorts derived from diverse European countries, adding evidence of variability in the levels of indoor endotoxin, extracellular polysaccharide, and β(1-3)-glucans across four geographically spread European regions.

TL;DR: A potential protective effect of Gram-positive bacteria in mattress dust is supported among adults across Europe and it is pointed out that this may be more pronounced in areas where microbial exposure levels are generally lower.
Indoor bacteria and asthma in adults: a multicentre case-control study within ECRHS II.

TL;DR: In a large international study, the level of Clostridium cluster XI was independently associated with a lower risk of prevalent asthma as mentioned in this paper, but no significant associations were observed for the three other qPCR assays used.

TL;DR: DNA fingerprinting proved useful in identifying bacterial signals that were associated with atopy in particular, and some of these bacterial groups may link to microbial exposure patterns that protect against development of atopic diseases.
