DOT ENZYME-LINKED IMIVIUNOSORBENT ASSAY (DOT-ELISA) AND PASSIVE HAEMAGGLUTINATION FOR THE DETECTION OF DUCK PLAGUE VIRAL ANTIBODIE

Abstract

Two hundred serum samples collected from ducks of different localities in Kerala were screened for the presence of antibodies to duck plague virus by dot ELISA and PHA. Of the 200 samples tested, 136 (68%} were positive by dot ELISA, the sensitivity and specificity being G7.64 and 43.75% respectively. The number of samples positive by PHA was 128 (64%). The sensitivity and specificity were 71.87 and 38.88%. The differences in the results obtained in these two tests were not statistically significant.
