abstract
The present study was carried out to evaluate the comparative study of Haemagglutination Inhibition test (HI) and competitive- ELISA (c-ELISA) in the PPR affected goats of Assam. A total of 456 serum samples were tested for detection of PPRV antibody by HI test and c-ELISA test. The test result indicated that, HI test was more sensitive and c-ELISA was more specific. The Chi-square analysis showed HI test was more significant than c-ELISA for detecting PPR viral antibody in the field conditions where sophisticated facilities and equipments are not available for diagnosis of PPR. Moreover, the HI test is also cheaper and less time consuming than c-ELISA.
