ascariasis /as·ca·ri·a·sis/ (as″kah-ri´ah-sis) infection with the roundworm Ascaris lumbricoides. After ingestion, the larvae migrate first to the lungs then to the intestine.

ascariasis

[as′kərī′əsis]

Etymology: Gk, askaris, intestinal worm, osis, condition

the most common parasitic infection in the world, caused by a parasitic worm, Ascaris lumbricoides, that migrates through the lungs in its larval stage. The eggs are passed in human feces, contaminating the soil and allowing transmission to the mouths of others through hands, water, or food. After hatching in the small intestine, the larvae travel through the wall of the intestine and are carried by the lymphatics and blood to the lungs. Early respiratory symptoms of coughing, wheezing, hemoptysis, and fever are caused by the passage through the respiratory tract. The larvae are swallowed; they mature in the jejunum, where they release eggs; and the cycle is repeated. Intestinal infection may result in abdominal cramps and obstruction. In children infection may cause stunted growth; migration of the adult worms into a child's liver, gallbladder, or peritoneal cavity may cause death. The infective eggs are readily identified in the feces. Piperazine citrate, pyrantel pamoate, mebendazole, and albendazole are effective treatments. The disease can be prevented by educating people, especially children, about good hygiene such as handwashing.

ascariasis

infection with Ascaris spp. The disease affects pigs, principally the young. Signs include poor growth, poor coat and diarrhea due to enteritis. Migration by the larvae results in the development of hepatitis and pneumonia. Other less common sequelae include biliary duct obstruction and a severe interstitial pneumonia when atypical larvae, e.g. Ascaris suis, infect cattle.

Infectious disease Infection by a nematode, Ascaris lumbricoides Epidemiology Infection occurs after ingesting eggs in contaminated food or more commonly, carried to mouth by hands after contact with contaminated soil; after an early pulmonary phase–larval migration, worms stay in the intestine Clinical Asymptomatic; pneumonitis at time of transpulmonary migration; diarrhea, abdominal colic Management Mebendazole, pyrantel pamoate
