Pilot study for the detection of pathogens causing cercarial dermatitis in Upper Austrian lakes by DNA barcoding
The pilot study aims to provide the basis for a genetic detection of pathogens causing cercarial dermatitis using the DNA barcoding approach. This includes
(1) establishing a reference database of DNA barcodes of potential pathogens (trematode larvae = cercariae) and their intermediate hosts (freshwater molluscs), and
(2) developing the basis for an eDNA approach to detect species of the genera Trichobilharzia and Bilharziella and its intermediate hosts.
For this purpose, water snails are collected and water samples are taken in selected Upper Austrian waters. The snails are used for cercarial release experiments to collect cercariae, from which the DNA barcodes are generated. Special attention is given to schistosomatid cercariae that cause dermatitis.

ABOL meeting 2019 – in retrospect17. December, 2019 - 16:19Dear ABOL community, this year, the ABOL meeting took place in Innsbruck for the first time. Gorgeous winter weather formed the framework for the 3-day event, which consisted of the first D-A-CH User Group Meeting (UGM) on the subject of DNA methods in environmental management and the 6th ABOL meeting. The first two days with […]
Elisabeth Haring spoke at the “Fridays For Future Vienna” strike on “Biodiversity and Climate Crisis”26. November, 2019 - 12:25Biodiversity is a term that is far from being firmly anchored in people’s minds. Global climate change can no longer be ignored as a fact, problem and danger, “Fridays for Future” is an expression of this situation. By contrast, the “Sixth Mass Extinction” is fully under way, yet many people are still unaware of the […]
