    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.
