Acute caprine fasciolosis: a case with unusual migration to lung.
Fasciolosis is an important parasitic disease of domestic ruminants and occurs worldwide as a result of infection with liver fluke species. This report describes the macroscopic and microscopic characteristics of acute fasciolosis in a goat with unusual migration to lung. A 10-month-old goat was presented with history of weakness and acute recumbency from 12 h ago. The clinicians didn't report clinical evidence of systemic disease. Hematological analysis showed no significant changes in blood parameters except a mild reduction in lymphocyte population and about 6 % eosinophilia and also normocytic normochromic anemia. A noticeable increase in the level of serum ALP, AST and also GLDH were observed. Moreover, total protein and albumin showed a slight decrease in value comparing to reference intervals. In macroscopic examination numerous short vermiform cords were noted on the liver surface and the surface had an uneven appearance. A large number of immature, wandering flukes were seen on the cut surface. Histopathologically, a wide range of hepatic lesions was found. The most important lesions were moderate to severe perihepatitis and haemorrhagic tracts on the hepatic surface. These lesions corresponded to migratory tunnels filled with blood, fibrin and cellular debris. However histopathological findings of lung revealed chronic suppurative bronchopneumonia, but this lesion is not only associated with larval migration.
