Abstract
Newcastle disease virus (NDV) strains isolated from outbreacks in and around Namakkal were characterized. The virus characterization in terms of mean death time (MDT), intraccrebral pathogenicity index (IVPI) were conducted as prescribed by Allan et al. (1978). Tests like stability of haemagglutinings at 56°C, agglutination of mammalian erythrocytes, adsorption of haemagglutinins by chicken brain cells and infectivity at pH 3.0 (Hanson et al. 1967) were carried out as per standard methods.
