An infection with an intestinal worm, the Ascaris Lumbricoides.
A disease of the intestine and sometimes the lungs, caused by infestation with Ascaris lumbricoides.
Infection with ascaris worms, acquired through feces-contaminated water or food. Symptoms may involve cough, wheezing, and fever or gastrointestinal complaints. Treatment is by piperazine and other drugs.
An infection caused by a parasitic roundworm. Ascariasis occurs when food or drink contaminated with roundworm eggs is ingested. When the eggs hatch, the roundworm’s larvae are released into the intestine. These larvae migrate through the intestinal wall into the bloodstream to the lungs, where they travel up the respiratory system and are swallowed. This returns the larvae to the intestines where they mature into adult roundworms. The mature round- worms live in the intestine and lay eggs that are expelled with the stool.
A disease caused by an infestation with the parasitic worm Ascaris Iiunbricoides. Adult worms in the intestine can cause abdominal pain, vomiting, constipation, diarrhea, appendicitis, and peritonitis; in large numbers they may cause obstruction of the intestine. The presence of the migrating larvae in the lungs can provoke pneumonia. Ascariasis occurs principally in areas of poor sanitation; it is treated with piperazine.
A disease produced by infestation with the roundworm Ascaris lumbricoides. Superficially it resembles a large earthworm and is most prevalent where sanitation and cleanliness are lacking, particularly in the tropics and subtropics. Consumption of food contaminated by the ova (eggs), especially salad vegetables, is the commonest cause of infection. After a complicated life-cycle in the body the adult worms end up in the intestines, whence they may be passed in the stools. A light infection may cause no symptoms, but a heavy infection may lead to colic, or even obstruction of the gut. Occasionally a worm may wander into the stomach and be vomited up.
Infestation by Ascaris lumbricoides, an intestinal parasite.
Infestation with the roundworm Ascaris lumbricoides, which lives in the small intestine of its human host. Ascariasis is common worldwide, especially in the tropics. One or several worms may be present, but symptoms usually only occur with heavy infestation.
The causative parasite of ascariasis is a pale, cylindrical, and tapered roundworm that can grow to a length of 15 to 35 cm in its adult stage.
Ascariasis is transmitted through the ingestion of worm eggs, typically from consuming food that has been cultivated in soil contaminated with human feces. Additionally, in arid and windy climates, airborne eggs may be inadvertently swallowed after being carried into the mouth by gusts of wind.
A mild infestation of ascariasis may not exhibit any noticeable symptoms, although individuals may experience slight nausea, abdominal pain, and irregular bowel movements. It is possible for an adult worm to be passed through the rectum or expelled by vomiting. In cases of a substantial worm burden, the parasites can compete with the host for nutrition, leading to malnutrition and anemia. In children, this can result in impaired growth and development.
Infestations of the worm are effectively treated with anthelmintic medications, such as levamisole, which typically result in complete recovery. After the administration of the drug, the worms are expelled from the body through the rectum several days later.
