The antibody response to Trypanosoma evansi antigens in rabbits experimentally infected with T. evansi was monitored by SDS-PAGE and "Western" blotting. As defined by the number of antigenic components recognised and the intensity with which they were labelled, responses were predominantly IgG, followed by IgM and IgA. During infection and subsequent drug treatment seven major antigenic components (94, 85, 75.5, 67, 60.5, 43, and 28.6 kDa) were identified by IgG. Antibodies to a 32.4 kDa and three other components (30, 28.6 and 12.5 kDa) appeared during infection and after chemotherapy respectively. Three components (94, 67 and 60.5 kDa) recognised by IgG were also detected by IgM and IgA. Furthermore, two bands (30 and 12.5 kDa) were identified by IgM and one (12.5 kDa) by IgA only after drug treatment, while a 28.6 kDa component was recognised by IgM and IgA during the same period. These findings constitute a basis for the exploration of class-specific antibody responses to T. evansi antigens with relevance to diagnosis, protection and pathology.

UI MeSH Term Description Entries
D007070 Immunoglobulin A Represents 15-20% of the human serum immunoglobulins, mostly as the 4-chain polymer in humans or dimer in other mammals. Secretory IgA (IMMUNOGLOBULIN A, SECRETORY) is the main immunoglobulin in secretions. IgA,IgA Antibody,IgA1,IgA2,Antibody, IgA
D007074 Immunoglobulin G The major immunoglobulin isotype class in normal human serum. There are several isotype subclasses of IgG, for example, IgG1, IgG2A, and IgG2B. Gamma Globulin, 7S,IgG,IgG Antibody,Allerglobuline,IgG(T),IgG1,IgG2,IgG2A,IgG2B,IgG3,IgG4,Immunoglobulin GT,Polyglobin,7S Gamma Globulin,Antibody, IgG,GT, Immunoglobulin
D007075 Immunoglobulin M A class of immunoglobulin bearing mu chains (IMMUNOGLOBULIN MU-CHAINS). IgM can fix COMPLEMENT. The name comes from its high molecular weight and originally was called a macroglobulin. Gamma Globulin, 19S,IgM,IgM Antibody,IgM1,IgM2,19S Gamma Globulin,Antibody, IgM
D007136 Immunoglobulins Multi-subunit proteins which function in IMMUNITY. They are produced by B LYMPHOCYTES from the IMMUNOGLOBULIN GENES. They are comprised of two heavy (IMMUNOGLOBULIN HEAVY CHAINS) and two light chains (IMMUNOGLOBULIN LIGHT CHAINS) with additional ancillary polypeptide chains depending on their isoforms. The variety of isoforms include monomeric or polymeric forms, and transmembrane forms (B-CELL ANTIGEN RECEPTORS) or secreted forms (ANTIBODIES). They are divided by the amino acid sequence of their heavy chains into five classes (IMMUNOGLOBULIN A; IMMUNOGLOBULIN D; IMMUNOGLOBULIN E; IMMUNOGLOBULIN G; IMMUNOGLOBULIN M) and various subclasses. Globulins, Immune,Immune Globulin,Immune Globulins,Immunoglobulin,Globulin, Immune
D011817 Rabbits A burrowing plant-eating mammal with hind limbs that are longer than its fore limbs. It belongs to the family Leporidae of the order Lagomorpha, and in contrast to hares, possesses 22 instead of 24 pairs of chromosomes.

D005260 Female Females
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. Animal,Metazoa,Animalia
D000913 Antibodies, Protozoan Immunoglobulins produced in a response to PROTOZOAN ANTIGENS. Protozoan Antibodies
D000953 Antigens, Protozoan Any part or derivative of any protozoan that elicits immunity; malaria (Plasmodium) and trypanosome antigens are presently the most frequently encountered. Protozoan Antigens
D014345 Trypanosoma A genus of flagellate protozoans found in the BLOOD and LYMPH of vertebrates and invertebrates, both hosts being required to complete the life cycle. Nannomonas,Trypanosomes,Nannomona,Trypanosome
