1. Development of cercarial dermatitis on the dorsal (1) and ventral (2) parts of the left hand of a sensitized volunteer infected experimentally by Trichobilharzia szidati (the whole hand was immersed into a beaker containing water with cercariae).
Development of cercarial dermatitis on the dorsal (1) and ventral (2) parts of the left hand of a sensitized volunteer infected experimentally by Trichobilharzia szidati (the whole hand was immersed into a beaker containing water with cercariae). Images were taken at 1 (A), 2 (B), 3 (C), and 4 (D) days postexposure. Formation of macules (A) and papules with vesicles (B to D) can be seen. No penetration/reaction was recorded for the palm. Noticeable swelling of the hand is shown mainly in panel B1. (The figure was created by H. Kulíková and P. Horák.)‏
