Diagnostic Value Of Antigen B In Hydatid Cyst By Dot-Blot Technique In The East Azerbaijan Province

Hydatidosis has been recognized as one of the most important zoonotic diseases in different parts of the world, including Iran. Serological methods that can detect hydatidosis with high sensitivity and specificity are have high value. In this study, the antigen B fluid of hydatid cysts was isolated and Dot-Blot technique performed on serum samples from human and sheep with hydatid cysts and healthy samples to evaluate their accuracy, sensitivity and specificity. After completing all stages of the dot blot test on 200 samples, it was found that the accuracy of the test in human cases is equivalent to 96% and in sheep cases it is equivalent to 92%. The sensitivity of this test is 92% in human cases and 84% in sheep. The test specificity is also 100% in both cases calculated. The evaluation of all of these cases indicates that B antigens have a high value in the diagnosis in hydatidiosis, and the dot blot technique using this antigen can be valuable as a diagnostic method and also as a method initial screening should be used.
