The existing embryo adapted vaccines pose field problems in the form of contaminating avian pathogens and in bulk antigen production. Use of heterologous cell systems and a local strain will help to overcome these problems. The present study describes the adaptability of two velogenic isolates from desi chicken to BHK21 (Razi) cell line to evolve a suitable candida...

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 ...

Colostral and serum immunoglobulin G (IgG, a major immunoglobulin class present in bovine colostrums and neonatal serum) levels were estimated in postpartum cows (Jersey and crossbred) and new born calves, respectively, at first milking and 24-48 hours postpartum, using single radial immunodiffusion (SRID) assay. Mean IgG concentrations (mg/ml) at first milking wer...

Cryopreservation technique allows to store cells at very low temperature for future use. For preservation of cells for long term storage, the addition of cryoprotective agents like dimethyl sulphoxide (DMSO) or glycerol and selection of suitable freezing and thawing rates was tried by Lovelock and Bishop (1959), Porterfield and Smith (1962) and Nachimuthu et...
