Nematodes
(Phyla of Pseudocoelomates) Information & Prevention
Phylum Nematodes (roundworms),
phyla of Pseudocoelomates, have been characterized as a "tube
within a tube," describing the fluid-filled cavity between
the outer body wall and the digestive tube. Nematodes are very small,
their size ranges from 400 micrometers to 5 mm. The majority of
Nematodes feed on bacteria, fungi, and other soil organisms; the
Nematodes that cause harm to humans, animals, and crops are parasitic
in nature living off of its host.
Nematodes are free-living, colorless, unsegmented, lack appendages,
and live almost everywhere on the face of the Earth. They have the
ability to cryptobiosis, or suspend their life processes completely
when conditions become bleak. It is no wonder that they have been
around since before mankind.
Well known parasitic Nematodes are: Hookworms,
Pinworms, Guinea
Worms, and Intestinal Roundworms. Practicing good hygiene is
the best way to prevent
an infestation of Nematodes. Children are very susceptible to
Nematodes since they like to handle pets and play in the dirt. "Dogs
and cats infected with these worms contaminate their surroundings
by passing eggs or larvae in their feces (waste). Because pets will
pass feces anywhere, they may contaminate a large area quickly.
These eggs and larvae are resilient and can survive in areas such
as parks, playgrounds, and yards. Even inside homes." CDC (Center
for Disease Control) A human can ingest the parasitic Nematode eggs
by contaminated soil.
