Metagonimus Yokogawai


Presentation

  • According to the former report ( Seo et al., 1981 ), the egg positive rate was 28.5%, a figure very similar to the present study.[doi.org]
  • However, present results indicated that ducks, based on the findings of this study, are not suitable hosts for establishment of M. yokogawai infection because most flukes were expelled from duck's intestine within 14 days.[pubag.nal.usda.gov]
  • Forming part of the Food Microbiology series, Laboratory Models for Foodborne Infections presents a state-of-the-art review of laboratory models that have proven valuable in deciphering the life cycle, epidemiology, immunobiology, and other key aspects[books.google.es]
  • Evidence also suggest that this parasite was present during the Yi dynasty.[en.wikipedia.org]
Fishing
  • Metagonimus yokogawai A 3-mm trematode/intestinal fluke found in fish harvested from the Mediterranean rim and the Far East, which may be ingested with improperly cooked fish (e.g., sushi). Treatment Praziquantel.[medical-dictionary.thefreedictionary.com]
  • 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]
Inflammation
  • Metagonimus yokogawai has adult flukes that parasitize the small intestine and causes inflammation.[en.wikipedia.org]
  • The affected villi undergo severe destruction with hemorrhages and inflammation, and finally the mucosa completely loses its integrity [ 339 ].[doi.org]
Falling
  • 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]
Fatigue
  • In heavily infected patients the infection can cause severe gastrointestinal troubles and easy fatiguability.[doi.org]
Asymptomatic
  • 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]
Gastric Pain
  • In light infections, anemia, eosinophilia, headache, dizziness, gastric pain, and loose stools can occur [ 383 ].[doi.org]
Suggestibility
  • 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]
Agitation
  • 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]

Workup

Paragonimus Westermani
  • Clonorchis sinensis (A), Metagonimus yokogawai (B), Trichuris trichiura (C, D), Ascaris lumbricoides (E, F), Paragonimus westermani (G, H), and Fasciola hepatica (I). Bar 20 μm.[doi.org]
  • ., the lung fluke Paragonimus westermani found in crayfish and crabs, the intestinal flukes Heterophyes heterophyes and Metagonimus yokogawai and the liver fluke Opisthorchis sinensis in fish, and the intestinal fluke Fasciolopsis buski on plants.[britannica.com]

Treatment

  • Treatment with hexylresorcinol failed to eradicate the infection, but subsequent use of tetrachloroethylene was successful and facilitated recovery of adult parasites, leading to the specific diagnosis of metagonimiasis.[ncbi.nlm.nih.gov]
  • Has a currently accepted medical use in treatment in the United States or a currently accepted medical use with severe restrictions.[drugs.com]
  • Treatment Praziquantel. Metagonimus yokogawai A species of intestinal flukes common in the Middle and Far East that normally infests the intestines of dogs, cats, and other animals, but is also commonly found in humans.[medical-dictionary.thefreedictionary.com]
  • Although anti-microbial treatments have played a crucial part in the control of foodborne infections in the past, the emergence and spread of anti-microbial resistance render the existing treatments ineffective.[books.google.es]
  • Among the treated cases, 11 were cooperative in collection of diarrheic stools more than five consecutive times during 3-4 hr directly after the treatment.[doi.org]

Prognosis

  • (Outcomes/Resolutions) The prognosis of Metagonimiasis is often good with proper administration of medication in a timely manner.[dovemed.com]

Etiology

  • (Etiology) Metagonimiasis is caused by the infection of the intestine by the parasitic Metagonimus yokogawai flatworm.[dovemed.com]

Epidemiology

  • Around this area, two epidemiological surveys were performed on M. yokogawai infection previously ( Seo et al., 1981 ; Ahn, 1984 ).[doi.org]
  • Thus, a small-scale epidemiological survey was carried out on some residents along the Tamjin River basin in order to determine the current status of M. yokogawai infection.[ncbi.nlm.nih.gov]

  • He joined the Centers for Disease Control and Prevention (CDC) in 1993, first as a guest researcher and then as a senior staff fellow.[books.google.es]
  • How can Metagonimiasis be Prevented? Prevention of Metagonimiasis may be possible by considering the following measures: Ensuring that fish and marine food are thoroughly cooked to prevent or greatly reduce the risk of infection.[dovemed.com]
  • […] thought that all the original specimens of H. yokogawai [ 1 ] and its synonyms Loxotrema ovatum Kobayashi, 1912 [ 9 ] and Yokogawa yokogawai Leiper, 1913 [ 17 ] were lost, so that a neotype should be designated for H. yokogawai, or now M. yokogawai, to prevent[doi.org]
