Studies have also indicated that pigs are the main source of human Ascaris
infections in areas considered to have no or low Ascaris
and hookworm eggs become infective as they mature in soil.
A roundworm specific to humans, Ascaris
lumbricoides, is rarely seen in developed countries.
To date, four cecropins, namely cecropin P1-P4, had been reported in Ascaris
suum which is a parasite found in gut of pig (Pillai et al.
lumbricoides is a parasitic nematode worm that primarily infects children in impoverished conditions throughout the tropics.
The samples revealed 118 'lemon-shaped' Trichuris trichiura eggs -- a type of roundworm commonly called the whipworm -- as well as 1,179 Ascaris
lumbricoides, or giant roundworm, eggs.
Gastrointestinal (GI) tract infestation with Ascaris
lumbricoides is a worldwide phenomenon with up to 25% of the world's population, mostly in the third world countries, infested with the worm .
London, Oct 29 (ANI): An international team of researchers has sequenced the draft genome of Ascaris
suum, a parasitic roundworm of pig, paving the way for the development of new and urgently needed interventions (drugs, vaccines and diagnostic tests) against ascariasis and other nematodiases.
The parasites found were: Ascaris
1637) evaluated the impact of a sanitation program implemented throughout the city of Salvador in Bahia State, Brazil, on infection with Ascaris
lumbricoides, Trichuris trichuria, and Giardia duodenalis in two cross-sectional studies of children aged 1-4 years.
Various genera of Protozoa (including Entamoeba, Endolimax, Iodamoeba, Balantidium, Giardia and Blastocystis), nematodes (such as Strongyloides, Trichuris, Ascaris
, Enterobius, Trichostrongylus and hookworms) and one trematode (a dicrocoeliid) were identified.
, Strongyloides and hookworm on the other hand have a larval stage that, after penetration of skin or mucous membranes, travels through the bloodstream to the lungs and migrates up the tracheobronchial tree, where they are swallowed and take up residence as adult worms in the gastrointestinal tract.
