species-specific antigen

spe·cies-spe·cif·ic an·ti·gen

antigenic components in the tissues and fluids of members of a species of animal, by means of which various species may be immunologically distinguished; for example, serum albumin of horses is immunologically different from that of man, dogs, sheep, and so on.

Daniel and Anderson [7], were the first to report on the species-specific antigen 5 of Mycobacterium tuberculosis, which was later proved to be the same as the 38-kDa protein [8].
ICT is immunochromato-graphic capture assays with monoclonal anti-bodies to species-specific antigens (histidine-rich protein2 [PfHRP2]), aldolase of plasmodium falciparum and conserved plasmodium antigens (lactate dehydrogenase).
suis), it is possible that our approach could have missed some interesting species-specific antigens. Although we ranked the 177 surface-associated proteins using adhesion, which is a crucial biological property strongly associated with a significant number of experimentally verified protective antigens, we cannot exclude the possibility that some potential antigens are missed from our "high-potential" 34 antigens.
However, as previously stated, the relative difficulty in managing Leishmania (Viannia) braziliensis can be an obstacle for species-specific antigens production.
The immunoglobulins were prepared from the ascetic fluid purified and tested by ELISA against different trypanosome species-specific antigens, Anaplasma marginale antigen, Babesia bijemina antigen Theeileria parva antigen, to establish their specificity.
