[Detection of blood group P1 activity in F. hepatica and F. gigantica (author's transl)]. 1979

R Ben-Ismail, and B Carme, and M Gentilini

Four lyophilizated liver flüke antigens and one of hydatid fluid were examined for the presence of blood group like antigens P1, A, B, M and N by an hemagglutination inhibition test with hyperimmune and natural hemagglutinating sera. P1 or P1-like substance was found in the extracts of "Fasciola hepatica" and "F. gigantica" in a lower concentration than in echinoccocal fluid. This presence may explain the occurrence of anti-P1 antibodies in patients infected with liver flüke and belonging to the P2 blood group. However biochemical studies will be necessary to determine if the P1 activity is due to the blood group P1 substance of the red cell itself or due to a P1 like substance.

UI MeSH Term Description Entries
D010127 P Blood-Group System A blood group related to the ABO, Lewis and I systems. At least five different erythrocyte antigens are possible, some very rare, others almost universal. Multiple alleles are involved in this blood group. Blood-Group System, P,Blood-Group Systems, P,P Blood Group System,P Blood-Group Systems,System, P Blood-Group,Systems, P Blood-Group

D005209 Fasciola A genus of trematode liver flukes of the family Fasciolidae. Two species of this genus are F. hepatica and F. gigantica. The parasites are found in the liver and gallbladder and associated ducts in mammals and occasionally man. F. gigantica occurs rarely in man. Fasciolas
D005210 Fasciola hepatica A species of helminth commonly called the sheep liver fluke. It occurs in the biliary passages, liver, and gallbladder during various stages of development. Snails and aquatic vegetation are the intermediate hosts. Occasionally seen in man, it is most common in sheep and cattle.

D006385 Hemagglutination Inhibition Tests Serologic tests in which a known quantity of antigen is added to the serum prior to the addition of a red cell suspension. Reaction result is expressed as the smallest amount of antigen which causes complete inhibition of hemagglutination.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D000941 Antigens Substances that are recognized by the immune system and induce an immune reaction. Antigen
