Acute caprine fasciolosis: a case with unusual migration to lung

Abstract

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.

“…• Postmortem examination: post-mortem examination revealed pale mucous membranes and pale subcutaneous tissues, hemothorax due to rupture of the lung, similar observations were noticed by some workers [7], hemoperitoneum due to rupture of the liver, both the cavities were filled with blood clots and free fluid containing blood. Various sizes of hematomas in liver parenchyma were noticed.…”

Detección de Fasciola hepatica por medio de ELISA indirecto en ovinos y caprinos de Boavita, Colombia

“…Clínicamente, la fasciolosis se considera una enfermedad debilitante crónica; sin embargo, en el ovino es más frecuente la enfermedad aguda o subaguda (Hayward et al, 2021), debido a una menor resistencia a este parásito, lo cual posibilita una mayor infestación y daño hepático, causando muerte súbita en estos animales (Munita et al, 2019). Por otro lado, la infección en el caprino generalmente evoluciona como una enfermedad crónica, aunque pueden ocurrir casos de fasciolosis subaguda y aguda con altas tasas de mortalidad (Hashemnia et al, 2015;Radostis et al, 2017). En general, la función hepática comprometida conduce a trastornos del metabolismo de carbohidratos, proteínas y grasas, lo que afecta la salud, el bienestar y la productividad de las ovejas y cabras infectadas (Sargison y Scott, 2011;Rokni, 2014).…”
