  1. Columns represent particular methods used for estimations. Relative volumes are indicated as percent of total volume of cercarial body (excluding tail). Absolute volumes are expressed in μm3 ± standard deviation. TEM, sections under transmission electron microscope; CM, optical sections under confocal microscope; ND, not determined.
