The mean number of metacercariae in a fish was in the range from 0 to 29,604 and the mean number of the metacercariae in a fish was 640.3. 2. It was observed that the mean infection rate showed 46.4% in Gangweon-Do ( Province). [eurekamag.com]

The infection rate and density of metacercariae in the fish were higher in eastern and western regions than in central region of the prefecture. [unboundmedicine.com]

The cercariae then penetrate the skin or go under the scale of a fresh or brackish water fish and encyst as metacercariae in the tissue. The type of fish that serves as secondary host varies based on location. [en.wikipedia.org]

This species was discovered by Fujiro Katsurada with egg samples from Japan and Taiwan With this discovery, he was able to make a new genus of trematodes that this new parasite would fall under "test" / The size of these eggs are about 29 μm. [en.wikipedia.org]

In heavily infected patients the infection can cause severe gastrointestinal troubles and easy fatiguability. [doi.org]

Patients repeatedly infected may complain of milder symptoms than primary infected patients, because most of the solidiers infected during survival trainings were asymptomatic [ 233, 234 ]. [doi.org]

In light infections, anemia, eosinophilia, headache, dizziness, gastric pain, and loose stools can occur [ 383 ]. [doi.org]

It is suggested that the endemicity of M. yokogawai infection along the Tamjin River has been reduced. To confirm this suggestion, the status of infection in snail and fish intermediate hosts should be investigated. [ncbi.nlm.nih.gov]

On examination of adult worms in the hamster's intestine, M. yokogawai was mainly located towards the anterior part of the intestine, unlike M. miyatai, suggesting that in mammalian host too, the parasites have site preference. [unboundmedicine.com]

Evidence also suggest that this parasite was present during the Yi dynasty. [en.wikipedia.org]

However, bile salts were not responsible for the excystation. 4) Agitation effect on the excystation was tested as a mechanical stimulus and it was found that the shaking stimulus accelerated the excysting mechanism, compared with the metacercariae on [parasitol.kr]
