Abstract

Aims: The purpose of this study was to evaluate the performance of the INDIRECT ELISA (I-ELISA) and COMPETITIVE ELISA (C-ELISA) for diagnosis of human BRUCELLOSIS in comparison to routine serological methods.Methods: Brucella abortus S99 used for LPS preparation. LPS extracted by hot phenol method with enzymatic digestion. Microtitre plates coated with LPS. For I-ELISA, binding antibodies to LPS revealed by peroxidase conjugated anti-human IgG1 and for C-ELISA, antibodies revealed by peroxidase conjugated mouse monoclonal antibody M84.Results: The cut off values (obtained by testing negative serum samples) were set at 17.92-21.63% positivity (P%) for I-ELISA and 53.29-56.91% inhibition (I%) for C-ELISA. The specificity for I-ELISA and C -ELISA were 95.5% and 99.5%, respectively. The sensitivity for I-ELISA and C-ELISA were 100% and 96.94%, respectively. The positive predictive value for I-ELISA and C-ELISA were 93.33% and 98.96%, respectively. The negative predictive value for I-ELISA and C-ELISA were 100% and 98.51% and overall agreement were 96.98% and 98.66%, respectively.Conclusion: The results indicate the potential of I-ELISA and C-ELISA as sensitive, specific, rapid and simple methods for diagnosis of human BRUCELLOSIS.
