Study Notes

Fecal Sedimentation

  • This is a method used to identify parasitic flukes in fecal matter.
  • The method is known to be effective in identifying the biggest flukes.

Endemic to North America

  • The parasite in this instance is endemic to North America

Human Parasite

  • The parasite is a human parasite.

Infectious Metacercaria

  • The parasitic metacercaria is found on plants.
  • The parasite's infection occurs when humans or pigs eat these contaminated plants.

Diagnostic Eggs

  • Diagnostic eggs of the parasite can be observed in fecal matter using a fecal sedimentation method.

Metacercaria Inhibits Development

  • Metacercaria inhibits the development of legs in the host.

Increased Viskness

  • The parasite infection in the host often leads to increased viscosity of the host.
  • The host may display multiple legs as an effect of being infected with the organism.
