& Human Parasitic Infestations
There are 15,000 known species
of roundworms, also known as nematodes,
and another half a million roundworms waiting to be discovered and
studied. That would make roundworms the second most diverse group
of animals. The first would be arthropods. Certain species of roundworms
can lay more than 200,000 eggs in one day. Most species of roundworms
have separate sexes, but there are a few that have both male and
Once the eggs are ingested in the body, the roundworm larvae travels
through the liver, lungs, and other organs. In most cases, these
"wandering worms" cause no symptoms or apparent damage.
It is when the larvae moves into the nerves or lodge themselves
in the eye that they can cause permanent damage or even blindness.
This condition is called visceral
Roundworms not only affect human health, but also the economy. The
root-knot nematode (Meloiodogyne Incognita) attacks cotton and other
nematodes can cause ear cockle nematode, (Anguina Titici) which
causes diseases in wheat.
Practicing good hygiene is the best way to prevent
an infestation of Roundworms. Children are very susceptible
to roundworms 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
roundworm eggs by contaminated soil.
