The serological response of naturally and experimentally infected lambs to orf virus infection was analysed using an enzyme-linked immunosorbent assay (ELISA) together with the Western blotting technique. The combination of these two methods permitted a qualitative and quantitative assessment of the response, which revealed considerable variation between animals. Despite this, all post-exposure sera reacted with a polypeptide (molecular weight 40 kilodaltons) which appears to be a component of the surface tubules that are characteristic of the virus.

UI MeSH Term Description Entries
D007118 Immunoassay A technique using antibodies for identifying or quantifying a substance. Usually the substance being studied serves as antigen both in antibody production and in measurement of antibody by the test substance. Immunochromatographic Assay,Assay, Immunochromatographic,Assays, Immunochromatographic,Immunoassays,Immunochromatographic Assays
D007700 Kinetics The rate dynamics in chemical or physical systems.
D009923 Orf virus The type species of PARAPOXVIRUS which causes a skin infection in natural hosts, usually young sheep. Humans may contract local skin lesions by contact. The virus apparently persists in soil. Contagious Ecthyma Virus of Sheep,Contagious Pustular Dermatitis Virus of Sheep,Ecthyma contagiosum Virus,Contagious ecthyma virus,Contagious pustular dermatitis virus,Sheep Contagious Ecthyma Virus,Sheep Contagious Pustular Dermatitis Virus,Contagious ecthyma viruses,Ecthyma contagiosum Viruses,Orf viruses,Virus, Ecthyma contagiosum,Viruses, Ecthyma contagiosum,ecthyma viruses, Contagious,virus, Contagious ecthyma,viruses, Contagious ecthyma,viruses, Orf
D011212 Poxviridae A family of double-stranded DNA viruses infecting mammals (including humans), birds and insects. There are two subfamilies: CHORDOPOXVIRINAE, poxviruses of vertebrates, and ENTOMOPOXVIRINAE, poxviruses of insects. Poxviruses
D004474 Ecthyma, Contagious An infectious dermatitis of sheep and goats, affecting primarily the muzzle and lips. It is caused by a poxvirus and may be transmitted to man. Contagious Pustular Dermatitis,Dermatitis, Contagious Pustular,Orf Virus Infection,Contagious Ecthyma,Contagious Pustular Dermatitides,Dermatitides, Contagious Pustular,Infection, Orf Virus,Infections, Orf Virus,Orf Virus Infections,Pustular Dermatitides, Contagious,Pustular Dermatitis, Contagious,Virus Infection, Orf,Virus Infections, Orf
D004797 Enzyme-Linked Immunosorbent Assay An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed. ELISA,Assay, Enzyme-Linked Immunosorbent,Assays, Enzyme-Linked Immunosorbent,Enzyme Linked Immunosorbent Assay,Enzyme-Linked Immunosorbent Assays,Immunosorbent Assay, Enzyme-Linked,Immunosorbent Assays, Enzyme-Linked
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
D000914 Antibodies, Viral Immunoglobulins produced in response to VIRAL ANTIGENS. Viral Antibodies
D000939 Epitopes Sites on an antigen that interact with specific antibodies. Antigenic Determinant,Antigenic Determinants,Antigenic Specificity,Epitope,Determinant, Antigenic,Determinants, Antigenic,Specificity, Antigenic
D000956 Antigens, Viral Substances elaborated by viruses that have antigenic activity. Viral Antigen,Viral Antigens,Antigen, Viral
