Natural immunity in cats to feline leukemia viral antigens. 1976

S K Ruscetti, and W P Parks

An isotopic antiglobulin assay was developed to measure antibodies in "normal" cats to FOCMA, a cell surface antigen associated with immunity to FeLV-induced tumors. The assay was shown to be specific for detecting FOCMA antibody by several criteria including a correlation with cell membrane immunofluorescence and absorption tests. Antibody to FOCMA developed following FeLV infection and was expressed in heterologous species. In combination with an assay for antibody to FeLV p30, the major virion structural protein, 200 cats sera from three different geographic areas were examined for evidences of FeLV-type-C-virus infection. Approximately 17% of all sera examined contained antibody to FOCMA. Antibodies directed to the FeLV p30 were detected in 8 of the sera and only in cats with FOCMA antibody. The correlation in cat sera between antibody to FOCMA and FeLV p30 antigen suggests that both are associated with the same process, infection with FeLV type-C-virus. The relationship of the observed pattern of antibody response is discussed in relation to other horizontally transmitted RNA-containing viruses.

D002143	Callitrichinae	A subfamily in the family CEBIDAE that consists of four genera: CALLITHRIX (marmosets), CALLIMICO (Goeldi's monkey), LEONTOPITHECUS (lion tamarins), and SAGUINUS (long-tusked tamarins). The members of this family inhabit the tropical forests of South and Central America.	Cebuella,Genus Mico,Leontocebus,Mico Genus,Callithricidae,Callitrichidae,Cebuellas,Genus, Mico,Mico, Genus
D002415	Cats	The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago.

D003298	Coombs Test	A test to detect non-agglutinating ANTIBODIES against ERYTHROCYTES by use of anti-antibodies (the Coombs' reagent.) The direct test is applied to freshly drawn blood to detect antibody bound to circulating red cells. The indirect test is applied to serum to detect the presence of antibodies that can bind to red blood cells.

D005455	Fluorescent Antibody Technique	Test for tissue antigen using either a direct method, by conjugation of antibody with fluorescent dye (FLUORESCENT ANTIBODY TECHNIQUE, DIRECT) or an indirect method, by formation of antigen-antibody complex which is then labeled with fluorescein-conjugated anti-immunoglobulin antibody (FLUORESCENT ANTIBODY TECHNIQUE, INDIRECT). The tissue is then examined by fluorescence microscopy.

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.
