Serodiagnosis of Sudanese visceral and mucosal leishmaniasis: comparison of ELISA--immunofluorescence and indirect haemagglutination. 1986

E R el Amin, and E P Wright, and A M Abdel Rahman, and A Kolk, and J J Laarman, and K W Pondman

Two established immunodiagnostic techniques, immunofluorescence and indirect haemagglutination, were compared with ELISA (enzyme-linked immunosorbent assay) using intact promastigotes as antigen for the detection of specific antibodies against Leishmania in the serum of patients with visceral or mucosal leishmaniasis from the Sudan. The ELISA was found to be more sensitive and more specific than either of the other two tests.

UI MeSH Term Description Entries
D007897 Leishmaniasis, Mucocutaneous A disease characterized by the chronic, progressive spread of lesions from New World cutaneous leishmaniasis caused by species of the L. braziliensis complex to the nasal, pharyngeal, and buccal mucosa some time after the appearance of the initial cutaneous lesion. Nasal obstruction and epistaxis are frequent presenting symptoms. Leishmaniases, Mucocutaneous,Mucocutaneous Leishmaniases,Mucocutaneous Leishmaniasis
D007898 Leishmaniasis, Visceral A chronic disease caused by LEISHMANIA DONOVANI and transmitted by the bite of several sandflies of the genera Phlebotomus and Lutzomyia. It is commonly characterized by fever, chills, vomiting, anemia, hepatosplenomegaly, leukopenia, hypergammaglobulinemia, emaciation, and an earth-gray color of the skin. The disease is classified into three main types according to geographic distribution: Indian, Mediterranean (or infantile), and African.

D003429 Cross Reactions Serological reactions in which an antiserum against one antigen reacts with a non-identical but closely related antigen. Cross Reaction,Reaction, Cross,Reactions, Cross
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.

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.

D014353 Trypanosomiasis, African A disease endemic among people and animals in Central Africa. It is caused by various species of trypanosomes, particularly T. gambiense and T. rhodesiense. Its second host is the TSETSE FLY. Involvement of the central nervous system produces "African sleeping sickness." Nagana is a rapidly fatal trypanosomiasis of horses and other animals.
