Where are Ascaris lumbricoides?
Ascaris parasites live in the intestine. Ascaris eggs are passed in the feces (poop) of infected people. If an infected person defecates outside (for example, near bushes, in a garden, or in a field), or if the feces of an infected person is used as fertilizer, worm eggs are deposited on soil.
Is Ascaris lumbricoides a Pseudocoelomate?
Ans: The body cavity of Ascaris is not covered by mesoderm in all sides. It is covered externally by muscle (Mesoderm) but internally the lining of intestine (Enodderm). So it is regarded as pseudocoelom.
What species of mammal is infected by Ascaris lumbricoides?
The species Ascaris lumbricoides is probably the most familiar parasite in humans. More than 25 percent of the world's human population is infected with these worms, and about 20,000 people die of Ascaris infestation yearly. An almost identical worm, often called A. suum, occurs in pigs.
What is the morphology of Ascaris lumbricoides?
Ascaris lumbricoides is characterized by its great size. Males are 2–4 mm (0.08–0.2 in) in diameter and 15–31 cm (5.9–12 in) long. The male's posterior end is curved ventrally and has a bluntly pointed tail. Females are 3–6 mm (0.1–0.2 in) wide and 20–49 cm (7.9–19 in) long.
How is Ascaris lumbricoides transmitted?
How is ascariasis spread? Ascaris lives in the intestine and Ascaris eggs are passed in the feces of infected persons. If the infected person defecates outside (near bushes, in a garden, or field), or if the feces of an infected person are used as fertilizer, then eggs are deposited on the soil.
What is Ascaris lumbricoides ova?
Ascaris lumbricoides, along with whipworm and hookworm, is a type of parasite known as a soil-transmitted helminth (STH). The roundworm lays eggs, which then pass in the person's stool, or poop. It can spread when an infected person defecates near farmland or crops.
What is the infective form of Ascaris lumbricoides?
The infective egg contains a second stage larva, coiled within the eggshell. Infection occurs when the infective eggs are ingested with contaminated food and water. The eggs hatch into larvae in the jejunum a few hours after being swallowed.
What is the intermediate host of Ascaris lumbricoides?
Human is the definitive host. There is no intermediate host. Tramission is human - feces - human. Adult ascarids live in the small intestines.
What is the treatment of Ascaris lumbricoides?
Anthelmintic medications (drugs that remove parasitic worms from the body), such as albendazole and mebendazole, are the drugs of choice for treatment of Ascaris infections, regardless of the species of worm. Infections are generally treated for 1–3 days. The drugs are effective and appear to have few side effects.
