SWIMMERS ITCH HIGGINS LAKE 2020 SKIN

The highest bird schistosome prevalence was observed for Bilharziella sp.

The overall digenean infection was 35.33%. In total, 317 specimens of pulmonate snails were collected and examined. The aim of the present study was to investigate the prevalence of the genus Bilharziella in comparison to other bird schistosome species from Lake Drawsko − one of the largest recreational lakes in Poland, struggling with the huge problem of swimmer's itch.

* Corresponding author: schistosomes are commonly established as the causative agent of swimmer's itch − a hyper-sensitive skin reaction to the penetration of their infective larvae.

We suggest other factors may also have influenced success, such as harassing and killing of mergansers (as opposed to just trapping and relocating), the distance of Higgins Lake from a costal waterfowl flyway, and lack of itch-causing parasite diversity. Our data suggests that a dramatic decrease in lake-wide snail density from 2016 to 2020, along with Stagnicola emarginata dominating the snail host community, help explain why merganser management has been successful on Higgins Lake and not on other lakes we have studied. Additionally, the magnitude of swimmer’s itch risk was assessed through qPCR analysis of swimmer’s itch-causing cercariae in water samples. Included in the survey were biodiversity assessments of the invertebrate smail hosts and the parasites. Patrick Hanington (University of Alberta), conducted a comprehensive survey of the schistosomes that are causative agents for swimmer’s itch on Higgins Lake in 2020. In general, we hoped to discover why several years of summer resident common merganser removal appeared to be effective on Higgins Lake, while similar remediation efforts on other lakes in NW Michigan were not.įreshwater Solutions (FWS), in collaboration with Dr. We proposed to the Higgins Lake Foundation that a repeat assessment of parasites and hosts responsible for causing swimmer’s itch on Higgins Lake would help answer some important questions, information that would advance the science of these itch-causing parasites and be beneficial to lake associations in Michigan and beyond.
