Helminthiasis caused by the parasitism of the fluke belonging to the 住胞吸虫科 Paragonimus genus with the lung distomiasis (はいきゅうちゅうしょう British: paragonimiasis).

Commentary
It is caused by Wes terman Paragonimus westermani (P. westermanii), Ohira Paragonimus westermani (P. ohirai), Miyazaki Paragonimus westermani (P. miyazakii), small Ohira Paragonimus westermani (P. iloktsuenesis), five kinds of the Sado Paragonimus westermani (P. sadoensis) in Japan. But I may treat triploid population of the Wes terman Paragonimus westermani as ベルツ Paragonimus westermani (P. pulmonalis) of the another kind by the habits and an infectious difference, and, in that case, as for the Paragonimus westermani from Japan, it is six kinds. In addition, the opinion to consider two kinds to be synonym of the Ohira Paragonimus westermani of the small Ohira Paragonimus westermani and Sado Paragonimus westermani is proposed. Of these, it is infected with Homo sapiens, and it is three kinds, the lung of the Homo sapiens of Wes terman Paragonimus westermani, ベルツ Paragonimus westermani, the Miyazaki Paragonimus westermani to be able to arrive at, and it grows to an imago to the lungs, and it is one kind of ベルツ Paragonimus westermani that can complete life cycles commonly. 28 kinds are considered to be an independence class in the world, and at least 11 kinds of human body parasitism is reported.
The ovum of parasites of the Paragonimus westermani is exhausted with discharge or expectoration with feces after the trachea, digestion. The ovum of parasites becomes ミラシジウム after growth in the water, and ミラシジウム invades it from the surface of a body of the shellfish which is the first intermediate host and grows to スポロシスト, a redia, a cercaria in the body. Because the cercaria which escaped from the body of the first intermediate host invades it from a surface of a body of the joint region of the crab (e.g., it is Eriocheir japonicus, Wes terman Paragonimus westermani in ベルツ Paragonimus westermani Sawa queen crab) which is the second intermediate host, I shift to the body and grow to a meta cercaria from a cercaria. It was said that I shifted to the body because a crab ate the first intermediate host, but was denied experimentally once. I shift to the small intestine of 終宿主 by 終宿主 taking in brachyuran and it bores it and moves the abdominal wall to the lungs through thoracic cavity and I form a pair and make an insect sac with the small intestine a de-bag.
Symptom
The symptom is wound-related hepatitis, peritonitis, hydrothorax retention, pneumothorax, fever, 発咳, bloody phlegm, and the blood views show the increase of the white blood-cell count with the number of the acidophile increase. When I invade brain, I show a headache, vomiting, an epileptiform attack, visual disorder and may die from the human body parasitism example. When it becomes the imago in the lungs, I can diagnose feces and expectoration by detecting an ovum of parasites through the deposition ova of parasites method such as the MGL method or the AMSIII method as materials.
Treatment
Praziquantel and bithionol are effective for treatment.
