Roundworm
Diseases - This is commonly caused by Ascaris lumbricoides, the largest of intestinal nematodes. Tropical and subtropical areas are the common foci of this disease. The nematode is like an earthworm. The female is over a foot long and the male somewhat smaller with a curled tail. Heavy infection may cause intestinal obstruction due to presence of tightly compacted masses of the parasite.
The
female
is
a
prolific
egg
producer,
sometimes
producing
200,000
per
day.
After
fertilisation
the
eggs
are
excreted
to
soil
where
they
hatch
to
larvae.
These
attach

Water
pollution
from

soil
and
contact

fingers
are
other
ways
of
transmission.
Roundworms
larvae
may

They
may
be
passed
to

causing
