Popis: Dot immunoassay was developed to improve the quality of laboratory diagnosis of brucellosis. Particles of colloid gold were used as a marker of specific antibodies. The method was used for detecting Brucella antigens in artificially contaminated environmental objects (soil and water) and in biological material (milk, blood serum, and visceral homogenates of animals). The sensitivity of the test system was 19.5.10(3)-62.5.10(4) CFU/ml. Specificity of the assay was tested with 10 heterologous antigenically closely related bacterial species. The proposed test system is simple, economic, highly sensitive and specific, and requires no expensive equipment and reagents.
