Reproducibility of allergen, endotoxin and fungi measurements in the indoor environment
TLDR
It is concluded that repeated measurements of mite and cat allergens and endotoxin in settled house dust improve the estimate for annual mean concentrations, and even a single observation of these biocontaminants may be a good proxy for a 1-year exposure since repeated measures were highly correlated. Expand
Predictors of high endotoxin concentrations in the settled dust of German homes.
TLDR
Results indicate that high endotoxin concentration in settled dust is an indicator of poor hygienic conditions in homes and associated with longer occupancy in the apartment. Expand
House dust endotoxin and allergic sensitization in children.
TLDR
Exposure to higher levels of house dust endotoxin is associated with lower prevalence of allergic sensitization in children, and the protective effect was strengthened with increasing degree of sensitization. Expand
Beta(1-->3)-glucan in house dust of German homes: housing characteristics, occupant behavior, and relations with endotoxins, allergens, and molds.
TLDR
The amount of dust sampled can be used as a proxy for hygiene and that beta(1-->3)-glucan concentrations per square meter are related to the amount of Dust sampled are concluded. Expand
Pets and vermin are associated with high endotoxin levels in house dust
TLDR
This work has shown that the risk for allergic sensitization is lower in children who grew up on farms and in young adults who were exposed to dogs in early childhood, and a higher microbial exposure in general and in particular to endotoxin in early Childhood might contribute to this lower risk of atopy.

Respiratory symptoms in relation to indoor exposure to mite and cat allergens and endotoxins. Indoor Factors and Genetics in Asthma (INGA) Study Group.
TLDR
Indoor exposure to Dermatophagoides farinae antigen 1 and cat antigen d1 is a risk factor for respiratory symptoms in adults, and forCat antigen d 1 even in nonsensitized subjects, and the risk is increased if subjects are exposed to a mixture of allergens or if they are sensitized in addition to high exposure.

Beta(1-->3)-glucan in house dust of German homes: housing characteristics, occupant behavior, and relations with endotoxins, allergens, and molds.
TLDR
The amount of dust sampled can be used as a proxy for hygiene and that beta(1-->3)-glucan concentrations per square meter are related to the amount of Dust sampled are concluded. Expand
Repeated measurements of allergens and endotoxin in settled house dust over a time period of 6 years
TLDR
This data indicates that exposure to indoor allergens and endotoxin during a time period of several years is related to adverse respiratory outcomes such as asthma, wheeze or others. Expand
Exposure to endotoxin decreases the risk of atopic eczema in infancy: a cohort study.
TLDR
The hygiene hypothesis that exposure to high concentrations of endotoxin very early in life might protect against the development of atopic eczema within the first 6 months of life, along with an increased prevalence of nonspecific respiratory diseases is supported. Expand
Allergens in house‐dust samples in Germany: results of an East–West German comparison
TLDR
The results indicate that the differences between the concentrations of mite and cat allergens found in Hamburg and Erfurt are explicable mainly, but not completely, by different building characteristics which affected the indoor climate, as well as by differences in other individual living habits.
