| Description |
English: Cercarial dermatitis ("swimmer's itch") on a human shank and ankle, four days after infestation. The bloodshot, puriginous skin vesicles (diameter ~5 mm) are caused by a — in this case harmless — infection with parasitic larvae (cercaria) of distinct Trematode species (probably Trichobilharzia ocellata / Trichobilharzia sp.). The most itching period is between the 2nd and 4th day after infection.
Deutsch: Badedermatitis am Unterschenkel und Knöchel einer bereits sensibilisierten Person, vier Tage nach dem (Fehl-)Befall. Die blutunterlaufenen, juckenden Quaddeln bzw. Ausschläge von ca. 5 mm Durchmesser wurden von parasitierenden Larven (= Zerkarien) bestimmter Saugwurmarten (Trichobilharzia sp.) in einem Weiher hervorgerufen. Eigentlich hatten sie eine Ente als Wirt nutzen wollen. Der Juckreiz war in diesem Fall etwa am fünften Tag verflogen; die roten Flecken wurden von da an sukzessive blasser und waren am zehnten Tag kaum mehr sichtbar (ohne Therapie). |
