Zusammenfassung

Vorratsmilben (VRM) sind wichtige Allergenquellen im Arbeitsbereich von Bauernhöfen in Deutschland. Die Untersuchung von 29 Staubproben aus zehn Hühnerställen zeigte eine hohe Abundanz und Stetigkeit von Hausstaubmilben (HSM). 92,1% aller nachgewiesenen Milben waren „domestic mites“ (DM = HSM + VRM), wobei 52,3% hiervon HSM repräsentierten. 13 DM-Arten (zehn VRM, drei HSM) wurden nachgewiesen. 24/29 Proben beinhalteten 2.452 HSM und 2.237 VRM (= 4.689 DM in 24 g Staub). Die kombinierte Bewertung nach Abundanz und Stetigkeit (Anteil Artindividuen an allen Milbenindividuen [%] + Anteil der artpositiven Proben an allen milbenpositiven Proben [%]: 2) zeigte die folgende Rangstufung: Lepidoglyphus destructor > Dermatophagoides farinae > Dermatophagoides pteronyssinus > Euroglyphus longior > Thyreophagus entomophagus > Glycyphagus domesticus > Acarus siro > Tyrophagus longior > Tyrophagus palmarum > Acarus immobilis > Glycyphagus geniculatus > Acarus farris > Gohieria fusca. Drei der fünf wichtigsten DM-Arten in den untersuchten zehn Hühnerställen waren sog. HSM.

Summary

Storage mites (SM) are important allergen sources in the working environment of German farms. Analyzing 29 samples of dust from ten henhouses, house dust mites (HDM) in both high abundance and steadiness were found. 92.1% of all mites found were domestic mites (DM = HDM + SM), whereby 52.3% of the DM found belonged to the HDM. 13 DM species (ten SM, three HDM) could be identified. 24/29 samples contained 2,452 HDM and 2,237 SM (= 4,689 DM in 24 g of dust). A combined evaluation summarizing abundance and steadiness (number of one species in total DM count [%] + occurrence of one species in all DM positive samples [%]: 2) showed the followings ranks: Lepidoglyphus destructor > Dermatophagoides farinae > Dermatophagoides pteronyssinus > Euroglyphus longior > Thyreophagus entomophagus > Glycyphagus domesticus > Acarus siro > Tyrophagus longior > Tyrophagus palmarum > Acarus immobilis > Glycyphagus geniculatus > Acarus farris > Gohieria fusca. Therefore, three of the most important five DM species found in the ten henhouses were so called HDM.
