Knowra Ascariasis Ascariasis Ascariasis is an intestinal infection caused by Ascaris roundworms, especially Ascaris lumbricoides in humans. Its life cycle includes larval migration through the lungs before adult worms mature in the intestine.
Ascaris lumbricoides : A parasitic roundworm that commonly infects humans and causes ascariasis. This species causes most human cases and follows the characteristic migratory life cycle.
Ascariasis diagnosis : Identification of Ascaris infection through clinical assessment, stool testing, or imaging. Microscopic detection of eggs in stool commonly confirms intestinal infection.
Löffler syndrome : A transient pulmonary syndrome marked by migrating lung infiltrates and eosinophilia, often caused by helminth larvae. Ascaris larval passage through the lungs can produce this temporary respiratory illness.
Trichuriasis : An intestinal infection caused by the whipworm Trichuris trichiura. Like ascariasis, it is a soil-transmitted helminth infection, but it involves a different worm.
Ascaris life cycle : The sequence by which Ascaris eggs develop, infect a host, and produce adult worms. Ingested eggs hatch in the intestine; larvae travel through the lungs before returning to mature.
Stool ova and parasite examination : Microscopic examination of stool for parasite eggs, larvae, or organisms. It can reveal characteristic Ascaris eggs, though early infections may yield negative results.
Ascariasis symptoms : The manifestations of Ascaris infection, which vary with parasite burden and life-cycle stage. Many infections cause no symptoms, while larval migration or heavy intestinal burdens can cause illness.
Hookworm infection : An intestinal infection caused by hookworms that enter the body through skin or ingestion. Hookworms share soil-related transmission but commonly infect through skin penetration and feed on blood.
Fecal-oral transmission : Transmission of pathogens when infectious material from feces enters another person’s mouth. People acquire ascariasis by swallowing eggs contaminating food, water, hands, or soil.
Albendazole : An antiparasitic medicine used to treat infections caused by many intestinal worms. A short course is commonly used to clear uncomplicated ascariasis.
