Rather than drying the skin with a towel. Or wading in infested water and then allowing water to evaporate off the skin Lakes in many parts of the world, including the Great Lakes region of NorthĪn individual may get the infection by swimming Swimmer's itch may be prevalent among bathers in Swimming or wading in shallow water and playing on the beach as the waterĮvaporates from the skin. All age groups and both sexesĬan be involved, but children are most often infected due to their habits of Infested water may experience this itchy rash. Only about one third of the people who come inĬontact with the parasite develop swimmer's itch. The parasite in man does not mature, reproduce or cause any These parasites remain in the skin and die but can cause an allergic reaction The water, and are capable of penetrating the skin of man. Life-cycle, these parasites are released from infected snails, migrate through Common grackles, red-winged blackbirds, ducks, geese, swans, muskratsĪnd moles have been found to carry the parasite.

Parasite (shistosomes) which ordinarily infect birds, semi-aquatic mammals, and Swimmer's itch is a skin rash caused by a If you are a leader of your lake association or organization, you should receive a second email from me this afternoon with spreadsheets of data we collected from your lake(s).įollowed by the NEW Swimmer's Itch Partnership (see details below)Įmail Sandra Michalik if you have a suspected case of swimmer's What is This might take us a little while, since I have several other high-priority papers to try to get out in the next year or two. Parasitology, at least once we have done some additional follow-up statistics to make sure we've covered all our bases. I think the key findings are likely publishable in a field-specific journal like J. Pleurocerids dominated the snail community at most sites. However, I later realized that this pattern was driven almost entirely by non-host snails (pleurocerids) and was therefore irrelevant to the swimmer's itch story.

We found support for our our hypothesized effect of water clarity on snail abundance.

This might be caused by vegetation blocking cercaria moving in from off-site, or the presence of beneficial plants like Bladderwort that can remove cercariae from the water.

There was a very strong negative association between submerged vegetation and cercaria levels, which seems to be a real biological pattern (i.e., not driven by statistical outliers or spurious correlations with other predictors).

Both patterns could plausibly be caused by a preference for colder water temperatures in this group of snails, which is mostly found at northern latitudes.

Stagnicola snails were associated with deeper lakes and sites with more deciduous (shade) trees).

Avian schistosome cercaria abundance was primarily driven by the abundance of Stagnicola (host) snails.In my opinion, the most interesting results were the following: Second, please find attached the revised (final) report about our work and findings. I am continually amazed and gratified by the amount of public interest and enthusiasm about this project. Raffel's summary is below.įirst, thanks to those of you who took time to attend my public presentations this past weekend, and who asked such insightful questions.
