A molecular approach was used to analyse a focus of cercarial dermatitis in northeastern France (Lake Der-Chantecoq), including both cercariae and snails,by sequencing the internal transcribed spacers (ITS1 for ocellate furcocercariae and ITS2 for snails). Lymnaea stagnalis were found infected with the furcocercariae of Trichobilharzia szidati, and T. franki furcocercariae were found in Radix auricularia. The record of these two visceral parasites of birds in northern France confirms strong host-parasite relationships. The use of these standardised markers will be of the highest significance for our understanding of the epidemiology of cercarial dermatitis in this recreational lake.

“…Outbreaks can lead to the closing of swimming areas and consequently to major financial losses for touristic operators. Several foci of HCD are well known in Europe, for example in Germany (Selbach et al 2015), France ( Jouet et al 2008), the Netherlands (Schets et al 2008), and Poland (Zbikowska 2004). It is worth mentioning that in Belgium, to the authors' knowledge, no cases were ever recorded in scientific literature.…”

Background: Cercarial dermatitis or swimmer's itch is a skin condition in humans due to the larval forms of bird schistosomes of some species of the genus Trichobilharzia. The life cycle of these schistosomes requires freshwater snails (intermediate host) and waterfowl (definitive host). Repeated exposures to cercariae can lead to skin sensitization with the induction of pruritic skin lesions. Methods: We describe, in this study, two outbreaks of human cercarial dermatitis at the Eau d'Heure Lakes, Belgium. In July and August 2012, a total of, respectively, 78 and 10 people reported a sudden skin rash accompanied by pruritus following recreational activities in the Plate Taille Lake. However, no ocellate furcocercariae were detected following light exposure of the snails collected between September 2012 and September 2013 (n = 402). No outbreaks were recorded in 2013 and 2014. In August 2015, about 30 new cases were recorded. Snails were collected (n = 270) in different locations around the lake. PCR was used to identify accurately the intermediate hosts and the parasite species involved. Results: After light exposure, seven Radix spp. (2.6%) shed ocellate furcocercariae. Molecular identification based on the rDNA internal transcribed spacer 2 sequence ascribed the infected snails to R. balthica ( = R. peregra = R. ovata) (6/7) and R. auricularia (1/7). Based on the amplification of the D2 domain of the 28S rDNA, the cercariae were shown to belong to two different haplotypes of Trichobilharzia franki. Conclusions: This is the first record in Belgium of T. franki and associated skin condition.

“…Cercariae then seek out their definitive host to complete their life cycle. The number of cercariae released each day can vary significantly between hundreds to tens of thousands of larval parasites and can be influenced by factors such as temperature, duration of infection, and immunogenetic determinants of snail-schistosome compatibility (Sluiters et al 1980; McCarthy 1999; Zbikowska 2004; Coady et al 2006; Gordy et al 2015; Soldánová et al 2016; Pila et al 2016). While the cercariae of some species of schistosome (those of the genus Schistosoma ) are known to infect humans, species of the genera Trichobilharzia, Gigantobilharzia, Dendritobilharzia, Anserobilharzia, and Schistosomatium cannot, but are able to penetrate human skin and lead to a condition known as swimmer’s itch (Cort 1928; Batten 1956; Kolářová et al 1999).…”

Swimmer’s itch (cercarial dermatitis) is a nuisance encountered by bathers and recreational water users worldwide. The condition is caused by the penetration of larval digenean trematodes (cercariae) of the family Schistosomatidae, into the skin, following their release into freshwater from pulmonate snails that serve as the intermediate hosts for these parasites. This study utilizes qPCR-based cercariometry to monitor and quantify cercariae from water samples collected at 5 lakes in northern Michigan. The resolution provided by qPCR facilitated assessment of the environmental and biological drivers of swimmer’s itch-causing cercariae concentrations, allowing us to demonstrate that cercarial abundance is greatest at the top of the water column, in locations with prevailing on- and alongshore winds.Electronic supplementary materialThe online version of this article (10.1007/s10393-018-1362-1) contains supplementary material, which is available to authorized users.
