Chicken lens spectrin is composed predominantly of equimolar amounts of two polypeptides with solubility properties similar, but not identical, to erythrocyte spectrin. The larger polypeptide, Mr 240,000 (lens alpha-spectrin), co-migrates with erythrocyte and brain alpha-spectrin on one- and two-dimensional SDS polyacrylamide gels and cross-reacts with antibodies specific for chicken erythrocyt...
Newcastle disease virus (NDV) is an economically important poultry pathogen with a worldwide distribution that may infect a wide range of domestic and wild avian species. The identification of different pathotypes of NDVs plays an important role in the diagnosis and development of vaccines to control and eradicate NDV infections. In our previous study, we showed that mono-specific antibodies ca...
Development and characterization of mouse monoclonal antibodies specific for chicken interleukin 18.
Four mouse monoclonal antibodies (mAbs) which are specific for chicken interleukin 18 (chIL18) were produced and characterized by enzyme-linked immunosorbent assay (ELISA), Western blotting, quantitative real-time PCR and neutralization assays. Using Western blot analysis, monoclonal antibodies specific for chIL18 identified a 23 kDa Pichia pastoris-expressed chIL18 and 66 kDa E. coli-derived M...
Vaccination programs to control Newcastle disease include use of low virulent live virus vaccines or inactivated vaccines to induce protective immunity. In order to further characterize the immune response elicited by live virus, we evaluated both cellular and humoral immune response to Newcastle disease virus (NDV) consequent to vaccine application by oculonasal and intranasal routes. Specific...
To detect antibody on pen-side is a rapid way to know the avian influenza (AI) infectious status in a chicken flock. The purpose of this study was to develop an immunochromatographic strip (ICS) assay to detect the antibody against the AI virus (AIV) for field applications. The ICS was constructed by fixing an AIV strain A/chicken/Taiwan/2838V/2000 (H6N1) onto a nitrocellulose membrane as the a...
background: the specific antibody response against newcastle disease virus (ndv) in the blood serum of chickens hatched from eggs exposed to low dose gamma-radiation was studied. materials and methods: two groups of eggs of commercial meat chicken lines were irradiated with the dose of 0.30 gy 60co gamma-rays before incubation and on the 19th day of incubation, respectively. the same number of ...
To generate monoclonal anti-idiotypic antibodies (mAb2) against avian influenza virus subtype H9 (H9 AIV), BALB/c mice were immunized with purified chicken anti-H9-AIV IgG and the splenocytes of immunized mice were fused with myeloma cells NS-1. Hybridoma cells were screened by indirect enzyme-linked immunosorbent assays with both chicken and rabbit anti-H9-AIV IgG as coating antigens. One hybr...
A human Hanganutziu-Deicher (HD) antibody and a chicken anti-N-glycolyneuroaminyllactosylceramide (HD3) antibody were compared in their reaction against HD antigen-active ganglioside (HD3) and a glycoprotein (GP) by radioimmunoassay (RIA). The human antibody had a 50 times higher reactivity with the glycoprotein, while the chicken antibody reacted equally with both antigens. Both antibodies had...
Riboflavin carrier protein (RCP) is a growth- and development-specific protein. Here, we characterized the expression of this protein in prostate cancer by polyclonal and monoclonal antibodies against chicken RCP. RCP was localized to both androgen-dependent and independent prostate cancer cell lines. Compared to controls, RCP was over-expressed in all 45 prostate adenocarcinomas, irrespective ...
AIM Chicken astroviruses (CAstV) are known to cause mild gastroenteritis, growth depression, and even mortality in poultry, especially in chickens, turkeys, and ducks. To the best our knowledge, there is no published information on CAstV in Grenada. This study was conducted to determine the prevalence of astrovirus in chickens in Grenada. MATERIALS AND METHODS Blood samples from 366 indigenou...
