Abstract
Adult distome flukes belonging to the genus Fasciola usually inhabit the liver, bile
ducts and gall bladder of their ruminant natural hosts. However, in unnatural hosts like
humans, and cases of peracute fasciolosis in natural hosts, F. gigantica can erratically
migrate to extra-hepatic sites and cause pathogenesis. This paper documents cases of
peracute fasciolosis among sheep in a private farm, with lesions in extra-hepatic organs
like lungs, heart and kidney. All examined cases were found to exhibit pulmonary
involvement characterized by circular, haemorrhagic lesions extending into the lung
parenchyma. Two cases of cardiac fasciolosis were documented in sheep for the first
time, with cardiac tamponade resulting from accumulation of blood in the pericardial
sac leading to death in one case. Haemorrhagic nephritis in sheep due to aberrant
migration of a single immature F. gigantica into the subcapsular spaces of kidney was
also recorded.
