The model organism Caenorhabditis elegans classified under the phylum Nematoda is amongst the most studied invertebrate species in glycobiology. The literature clearly documents a repertoire of nematodal paucimannosidic glycans. Another model nematode, Pristionchus pacificus, was also documented to express common nematodal paucimannosidic glycans.
Parasitic nematodes such as Haemonchus contortus have been reported to carry paucimannosidic glycans conjugated to an intestinal microsomal aminopeptidase. In addition, there have been reports documenting the expression of paucimannosidic glycans by others parasitic nematodes such as Ascaris suum, Heligmosomoides polygyrus and Trichuris suis.
