“…After the parasite's egg is ingested by the intermediate hosts, the embryo, which is released from the egg, which is broken down by the effect of bile salts in the duodenum, passes through the jejunum and ileum wall to the portal vein, periduodenal and perigastric lymphatics and reaches the liver first. For this reason, it has been reported that the liver is affected first at a rate of 60-70%, and the lungs are the location of the agent at a rate of 20-25%, except for the liver , Tilkan et al, 2018, Wen et al, 2019.
