The Clinical Measurement Ontology (CMO), Measurement Methods Ontology (MMO), and Experimental Condition Ontology (XCO) are currently being developed at the Rat Genome Database. For more information about these vocabularies please see Shimoyama et al. Three ontologies to define phenotype measurement data. Front Genet. 2012;3:87.

A measurement related to anti-parasite antibodies in blood, the fluid that circulates through the heart, arteries, capillaries and veins carrying nutrients and oxygen to the body tissues and metabolites away from them. An anti-parasite antibody is an immunoglobulin molecule possessing a specific amino acid sequence that binds to a specific antigen found on or in a parasite, an organism that grows, feeds, and is sheltered on or in a different organism while contributing nothing to the survival of its host and possibly causing damage to that host. An antigen is a substance introduced into an organism which initiates an immune response, including the production of the very antibodies which bind to it in an effort to destroy it.
