Ecological factors in schistosome transmission, and an environmentally benign method for controlling snails in a recreational lake with a record of schistosome dermatitis.
However, these have not been fully applied for the detection of infections in snails under field conditions.
Each replicate line was maintained in large (51i31 cm) tanks containing 60 snails of matched compatibility selection status, with no intervention on mating strategy incorporated.
In most habitats, infections were recorded in both cattle and snails.
Overall, 51n04 % of snails were infected (range across 9 sites l 8n7-100 %) with 1 or more species.
Only 8.0% of the snails with shell length 15 mm were infected, in contrast to 98.0% of the snails with shell length > 26 mm.
