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 pyoderma consisting of three forms of skin lesions having either a thick, adherent, recurrent, dirty yellow crust with an erythematous margin (common or superficial impetigo) or lessions which are superficial, thin-walled, and bullous as found in bullous impetigo. The lesions in bullous (staphylococcal) impetigo, which are always caused by S aureus, are superficial, thin-walled, and bullous. (DO)
