Ascaris lumbricoides and Ascaris suum are widespread parasitic nematodes of humans and pigs respectively. Recent prevalence data suggests that approximately 1.2 billion people are infected. Adult worms exhibit an overdispersed frequency distribution in their hosts and individuals harbouring heavy burdens display associated morbidity. In this review, we describe the parasite, its distribution an...

This is a case presentation of a multiple trauma patient who was infested with Ascaris lumbricoides, a roundworm. The infestation was undiagnosed until after extubation. Intraoperative anesthesia was uneventful and the patient was discharged 7 days after admission.

The taxonomic status of Ascaris lumbricoides and A. suum is contentious: shall they be considered a single species? Yes, as argued by Leles et al. [1], and most recently debated through opposing views by Alves et al. [2] and Betson et al. [3]. Most taxonomic literature refers to two species, and results from investigations of the nuclear DNA of Ascaris isolates of human and pig origin suggest t...

Although it is the most prevalent helminth worldwide, Ascaris lumbricoides rarely invades the stomach. Ascaris infestation may produce gastrointestinal or biliary obstruction, liver abscess, pancreatitis, volvulus, intussusception, acute appendicitis, occult gastrointestinal bleeding, and anemia. We report here on a case of acute upper gastrointestinal bleeding in a patient with gastric ascaria...

Ascaris suum and Ascaris lumbricoides are two closely related geo-helminth parasites that ubiquitously infect pigs and humans, respectively. Ascaris suum infection in pigs is considered a good model for A. lumbricoides infection in humans because of a similar biology and tissue migration to the intestines. Ascaris lumbricoides infections in children are associated with malnutrition, growth and ...

BACKGROUND Ascaris lumbricoides infections are one of the commonnest intestinal nematode infections in the world, with a profound negative effect on nutritional status among underprivileged populations. In Sri Lanka, Ascaris infections and low nutritional status still persist in the plantation sector. However, research regarding the association between Ascaris infections and nutritional status ...
