Knowra Ascaris lumbricoides Ascaris lumbricoides Ascaris lumbricoides is a large parasitic nematode that lives in the human small intestine. Its eggs pass in feces, and infection occurs when people ingest embryonated eggs.
Ascaris life cycle : The sequence in which Ascaris eggs develop in soil, hatch after ingestion, migrate through the lungs, and mature in the intestine. This cycle explains how intestinal adults arise from swallowed eggs.
Stool ova and parasite examination : Microscopic examination of stool for parasite eggs, larvae, or other diagnostic stages. Ascaris eggs in stool commonly confirm intestinal infection.
Nematode : A member of a diverse phylum of unsegmented, cylindrical worms with a complete digestive tract. Ascaris belongs to this animal phylum and shares its basic body plan.
Soil-transmitted helminth control : Public-health measures that reduce infection and transmission by worms whose infective stages develop in soil. Ascaris control combines treatment with sanitation and hygiene measures.
Ascariasis : An intestinal infection caused by Ascaris worms, sometimes complicated by worm migration or intestinal obstruction. This is the disease produced by the species and its life cycle.
Albendazole : A benzimidazole antiparasitic drug that disrupts microtubule formation in susceptible worms. It is commonly used to treat intestinal Ascaris infection.
Helminth : A parasitic worm, including species from several distinct animal groups. The term places Ascaris among the worms studied in parasitology.
Nutritional consequences of helminth infection : Effects of worm infections on nutrition, including impaired intake, absorption, or growth in some settings. Heavy Ascaris infections can contribute to nutritional and growth problems, especially in children.
Fecal–oral transmission : The spread of pathogens when fecal contamination reaches another person’s mouth, often through food, water, or hands. Ascaris eggs reach people through contaminated soil, food, or water.
Mebendazole : A benzimidazole drug used to treat infections caused by several intestinal worms. It is another standard treatment that acts against adult Ascaris.
