Allergen Details:

Allergen name: Asc l 13
Allergen source: Major taxonomic group: Animalia Nematoda
Order: Ascaridida
Species: Ascaris lumbricoides (Common roundworm)
NCBI Taxomony ID: 6252
Biochemical name:Glutathione S-transferase (GST)
Allergenicity:26 (90%) of 29 patients exposed to A. lumbricoides with positive CAP to A. lumbricoides showed IgE binding to purified natural Asc l 13 in ELISA. Of 12 patients tested by SPT with nAsc l 13, 5 (42%) reacted. The identity of the natural purified Asc l 13 was established by sequencing 73% of the protein by MS/MS.
Allergenicity reference:PubMed:24223794
Route of allergen exposure:Food

The glutathione transferase of Ascaris lumbricoides and Ascaris suum are nearly identical. Serum IgE from a number of subjects in Cartagena showed IgE binding to both in the published article in PLOS ONE.
