Background: To determine the morphological specifications of the bird schistosomes cercaria from Lymnaea
gedrosiana and to detect the surface carbohydrates as receptors for host lectins in the host-parasite
relationship systems such as avian schistosomiasis and human cercarial dermatitis.
Methods: One hundred ninety two snails collected from Dezful areas in Khuzestan Province, in the south
west of Iran, during 2005-2006 were examined for cercariae using shedding and crushing methods. In
addition, surface carbohydrates on the cercariae were detected by lentil (Lens culinaris) lectins.
Results: From the total number of Lymnaea gedrosiana, which examined for bird schistosomes cercaria,
9(4%) snails were found to be infected with furcocercus cercaria of the bird schistosomes (probably
Gigantobilharzia sp.). Mannose monosaccharide CH2OH (CHOH)4CHO as surface carbohydrate was also
detected on the cercariae.
Conclusion: Mannose carbohydrate on these cercariae may be used as receptor by lectins.
