Variations in immunofluorescent antibody response against Trichobilharzia and Schistosoma antigens in compatible and incompatible hosts

“…At present, the infection is regarded as an emerging problem associated with swimming and other aquatic activities (Eklu-Natey et al 1985;Baird and Wear 1987;De Gentile et al 1996). In Europe, the most frequent causative agents of swimmer's itch are cercariae of the bird schistosome genus Trichobilharzia (Kola´rˇova´et al 1997) which mature in the viscera (Trichobilharzia ocellata, Trichobilharzia szidati and Trichobilharzia franki : Brumpt 1931;Neuhaus 1952;Mu¨ller and Kimmig 1994) or in the nasal cavities (T. regenti: Hora´k et al 1998a).…”

“…Reactions following the first contact of man with either human or animal schistosome cercariae are usually mild; however, re-exposure to the cercariae may stimulate the severity of the skin infection (Eklu-Natey et al 1985;Kola´rˇova´et al 1997). Contrary to the infections caused by Schistosoma cercariae, the invasion of schistosome cercariae with animal hosts results in a more severe response (Basch 1991).…”

Infection of snails with bird schistosomes and the threat of swimmer?s itch in selected Polish lakes

“…Dermatitis caused by cercariae of bird schistosomes has been described in nearly all continents (Cort 1936;Hunter et al 1949;Jarcho and van Burkalow 1952;Macy 1952;Hoeffler 1974;Suzuki and Kawanaka 1980;Leedom and Short 1981;Appleton 1984;Eklu-Natey et al 1985;Blankenspoor and Reimink 1988;Narain et al, 1994;Loken et al 1995;Lindblade 1998). In recent years there has been considerable interest in bird schistosomes among researchers in Europe, no doubt associated with the ever increasing number of reported cases of swimmerÕs itch in that part of the world (De Gentile et al 1996;Pilz et al 1995;Thors and Linder 2001;Dubois et al 2001;Canestri-Trotti et al 2001;Kolarova et al 1999;_ Zbikowska et al 2001).…”

Extension D’une Espèce Envahissante : Suivi De La Population D’écrevisses Signal (Pacifastacus Leniusculus Dana) Au Léman À L’ouest De Thonon-Les-Bains, Entre 2001 Et 2005 – Impact De La Pêche

“…C'est enfin un moyen indirect de contrôle de la dermatite du baigneur, dont l'impact touristique n'est pas négligeable en saison estivale. En effet les limnées véhiculent un Trématode, Trichobilharzia sp., qui parasite les canards (HORAK et al, 2002) et provoque chez le baigneur de fortes démangeaisons (EKLU-NATEY et al, 1985). Nous avons observé que les cas de dermatite étaient en forte diminution dans les zones colonisées par les écrevisses (DUBOIS et KNOCKAERT, 2004).…”
