Paragonimus westermani eggs range from 80-120 µm long by 45-70 µm wide. They are yellow-brown, ovoid or elongate, with a thick shell, and often asymmetrical with one end slightly flattened. At the large end, the operculum is clearly visible. The opposite (abopercular) end is thickened.

Paragonimus westermani (Japanese lung fluke or oriental lung fluke) is the most common species of lung fluke that infects humans, causing paragonimiasis. [2] Human infections are most common in eastern Asia and in South America.

Paragonimiasis (pronounced “pare-uh-gone-uh-MY-uh-sis”) is a parasitic infection with any of several species of Paragonimus flukes, a type of flatworm. You get it from eating raw, undercooked or pickled crab or crayfish.

2024年9月9日 · Several species of Paragonimus cause most infections; the most important is P. westermani, which occurs primarily in Asia including China, the Philippines, Japan, Vietnam, South Korea, Taiwan, and Thailand. P. africanus causes infection in Africa, and P. mexicanus in Central and South America.

2020年7月28日 · Paragonimiasis, or lung fluke disease, is caused by infection with a number of species of trematodes belonging to the genus Paragonimus.

2023年2月24日 · Paragonimus westermani is the etiological agent of pulmonary paragonimiasis or hemoptysis in humans. It is a lung fluke which is most common in eastern Asia and in South America. The infective form of the parasite is the metacercaria.

Paragonimus westermani is the lung fluke endemic to Southeast Asia. The usual clinical presentation is that of pleuropulmonary disease. The most common extra-pulmonary manifestation is cerebral paragonimiasis, including meningitis. Patients can present with acute-onset fever, headache, and vomiting.

Paragonimiasis is infection with the lung fluke Paragonimus westermani. Flukes are parasitic flatworms that infect various parts of the body (eg, blood vessels, gastrointestinal tract, lungs, liver) depending on the species.

Paragonimus westermani is a common parasite of humans, and it has been used for research purposes to help better understand trematode infections. Positive Impacts; research and education; Economic Importance for Humans: Negative. Paragonimiasis is a parasitic infection caused by Paragonimus westermani.

The name ‘Paragonimus westermani’ has been applied to sequences from most members of that complex for convenience. The tree includes five sequences not previously available in public databases (indicated with an asterisk), all obtained from metacercariae identified to nominal species on morphological grounds.
