Ascariasis is a disease caused by the parasitic roundworm Ascaris lumbricoides. [1] Infections have no symptoms in more than 85% of cases, especially if the number of worms is small. [1] Symptoms increase with the number of worms present and may include shortness of breath and fever at the beginning of the disease. [1]
Ascaris lumbricoides is a large parasitic roundworm of the genus Ascaris. It is the most common parasitic worm in humans. [1] An estimated 807 million–1.2 billion people are infected with Ascaris lumbricoides worldwide. [2] People living in tropical and subtropical countries are at greater risk of infection.
One species, Ascaris lumbricoides, affects humans and causes the disease ascariasis. Another species, Ascaris suum, typically infects pigs. Other ascarid genera infect other animals, such as Parascaris equorum, the equine roundworm, and Toxocara and Toxascaris, which infect dogs and cats. Their eggs are deposited in feces and soil.
Female Ascaris lumbricoides. Ascariasis of STH is caused by the large roundworm A. lumbricoides. It is estimated to be the most widespread STH, affecting approximately 1 billion people. The victims constitute about half of the populations in tropical and subtropical areas. Most conditions are mild and often show little or no symptoms. Heavy ...
Ascaris suum, also known as the large roundworm of pig, is a parasitic nematode that causes ascariasis in pigs.While roundworms in pigs and humans are today considered as two species (A. suum and A. lumbricoides) with different hosts, cross-infection between humans and pigs is possible; some researchers have thus argued they are the same species.
