RESUMO

Analysis of 45 sera was performed employing five techniques which are currently in use in three laboratories to measure anti-Pasteurella haemolytica antibodies. The enzyme linked immunosorbent assay, passive hemagglutination, complement fixation and direct and indirect bacterial agglutination assays were employed and a relationship between tests in the measurement of anti-P. haemolytica antibodies was demonstrated. Regression analysis together with prediction and confidence intervals were tabulated also. The conclusion drawn from statistical analysis was that all five tests are similar in their ability to detect immune responses (antibody and antigen(s) interactions) to Pasteurella haemolytica.
