Question: What are the symptoms of the disease caused by the Nematode? Passage 1:He made his American stage debut as the romantic lead opposite Gladys George in Lady in Waiting. Though his film career had begun in Britain in the 1930s, he had very little success before the cameras until he joined the British expatriate community in Hollywood in 1941. There he spent time with such people as James Whale, a fellow ex-Oxford Player. He appeared in such films as Random Harvest (1942), Cat People (1942), and The Uninvited (1944). In The Song of Bernadette (1943), he played the ethically questionable psychiatrist who is hired to declare Bernadette mentally ill. He also played the vicious Earl of Warwick in Joan of Arc (1948). He performed in two Shakespearean films: the Orson Welles Macbeth (1948), in which he played a priest that Welles added to the story, who spoke lines originally uttered by other characters, and MGM's Julius Caesar (1953), as Cicero. He appeared as Mr. Rutland in the Hitchcock movie Marnie (1964).
 Passage 2:Founded in 1991 as the pro-free market wing of the Civic Forum by Václav Klaus and modelled on the British Conservative Party, the ODS won the 1992 legislative election, and has remained in government for most of the Czech Republic's independence. In every legislative (except for the 2013 election) it emerged as one of the two strongest parties. Václav Klaus served as the first Prime Minister of the Czech Republic after the partition of Czechoslovakia, from 1993 to 1997. Mirek Topolánek, who succeeded him as leader of the party in December 2002, served as Prime Minister from 2006 to 2009. In the 2010 election, the party lost 28 seats, finishing second, but as the largest party right of the centre, it formed a centre-right government with Petr Nečas as Prime Minister. In the 2013 legislative election, the party was marginalized by only securing 16 seats in the Chamber of Deputies, relegating the party to the opposition since July 2013. In the 2017 legislative election, it has partly recovered and secured 25 seats in the Chamber of Deputies, making it the second strongest party in chamber. The party is currently being led by Petr Fiala, who has been leader since the 2014 party convention.
 Passage 3:In humans C. hepatica causes Hepatic capillariasis, a serious liver disorder. The Nematode wanders through the host liver causing loss of liver cells and thereby loss of function. However, as the adult C. hepatica begin to die in the liver tissue, their decomposition accelerates the immune response of the host. This response leads to chronic inflammation and Encapsulation of the dead worms in collagen fibers, and eventually to septal fibrosis (abnormal connective tissue growth) and cirrhosis of the liver. This leaves the eggs behind and they can become encased by Granulomatous tissue, with large sections of the Parenchyma becoming replaced by these egg masses. Capillaria hepatica can also cause Hepatomegaly. Infections of C. hepatica can present with several clinical symptoms including, abdominal pain in the liver area, weight loss, decreased appetite, fever and chills, hepatitis (liver inflammation), ascites (excess fluid in the peritoneal cavity) and hepatolithiasis (gallstones in the bile ducts).
