RGD uses the Human Disease Ontology (DO, https://disease-ontology.org/) for disease curation across species. RGD automatically downloads each new release of the ontology on a monthly basis. Some additional terms which are required for RGD's curation purposes but are not currently covered in the official version of DO have been added. As corresponding terms are added to DO, these custom terms are retired and the DO terms substituted in existing annotations and subsequently used for curation.
A parasitic helminthiasis infectious disease that involves infection of the intestine with the nematode Ascaris lumbricoides. Larvae migrating through the lungs cause cough, wheezing and hemoptysis. Bowel or biliary obstruction causes cramping abdominal pain, nausea, and vomiting. Peritonitis, enlargement of the liver or spleen, toxicity and pneumonia are observed when larvae get into the portal circulation. (DO)
