F. jacksoni recovered from infected liver and lungs were almost round, pear-shaped measuring 10-16 mm in length and 8.5-14 mm in width with ill-defined cephalic end between indistinct shoulders. The intestine was extensively branched. The yellowish tinged ova were oval with an operculum at one end and measured 0.112-0.160 (mean 0.13) mm in length and 0.054-0.096 (mean 0.07) mm in width. Infected liver showed haemorrhagic tracts, thickening of bile ductules, cirrhotic changes and pseudolobulations. In the lungs, the bronchial lumen contained desquamated cells admixed with fibrinohaemorrhagic exudate.
