Conteúdo: | Abstract : In a flock of 40 lambs grazing from April 1967 onwards on a pasture with a previous history of fascioliasis, clinical signs first became apparent in early October. Between then and March 1968 all of the lambs died or were killed in extremis, all but five before the end of December 1967. None of the lambs developed the acute fascioliasis syndrome (sudden or very rapid death not preceded by clinical signs, due to large numbers of migrating parasites). All those dying between October and December had severe subacute fascioliasis. Both migratory forms of the fluke were found in hepatic parenchyma and adults in bile ducts. The principal clinical signs were weight loss, dullness, pallor of visible mucous membranes and sensitivity to anterior abdominal palpation. Submandibular oedema and ascites were uncommon. The anaemia was macrocytic and hypo-chromic, and reticulocytosis was characteristic. Initially, there was an increase in serum globulin, with a subsequent progressive fall in both albumin and globulin levels. Clinical signs in the other five lambs were similar, but developed at a slower rate. Total fluke recoveries (all lambs) ranged from 110 to 1, 628. Immature stages represented 90% of the burden in October but in the lamb killed in March 1968 87% of flukes were adult.
