Abstract On the basis of cell-penetrating peptide’s character that it can penetrate cytomembrane and transfer macromolecular protein to cytoplasm so to play biological function, we took the experiments. The fuse penetrating peptide our experiment adoptted is HIV-TAT derived fragment-CTP512, with good transmember effect and distinct cytoplasm-position. In this chapter, the research of transmembrane character was processed first. According to the tests on trans- member protein with different concentrations, the best trans-member concentration is 3µM. Afterwards, we found that the location of trans-member antibody is overlapping with phosphoprotein using indirect immunofluorescence test analysis. According to MTT test, there is no significant difference between CTP fusion protein and control on cell proliferation and viability. TCID50 test was used to detect the protective effect of trans-member antibody on cell. Result showed that trans- member antibody has significant cell protection effect compared to the control in the order: ZL.103>ZL.17>Control. Fluorogenic quantitative PCR result showed that trans- member antibody can disturb the duplication and transcription of Newcastle disease virus. This results not only paved a good way to research the transport of disease related protein, but also provide a splendid tool on protein function research.

This research aimed to express and purify the recombinant Fusion (F) protein of Newcastle Disease Virus (NDV) from a local isolate in Galur, Kulon Progo, Indonesia (0663/04/2013) from recombinant vector plasmid pBT7-N-His F, and to study the antibody response in the broiler sera which were injected with pure recombinant F protein compared with treated broilers that were vaccinated with commercial inactive NDV vaccines and control broilers without vaccination. The results showed that the recombinant F protein of NDV was successfully expressed, purified and visualized by SDS-PAGE with Coomassie Brilliant Blue staining and Westernblotting methods as a specific recombinant F protein with a molecular weight of 28 kDa. The pure recombinant F protein then was injected into broilers to determine the antibody response in broiler serum. Indirect ELISA showed that the production of antibodies was high in F protein vaccinated groups in comparison with other treated and control groups. The recombinant F protein has potential to be developed as a recombinant vaccine candidate after truncating the 6x His-tag part to obtain higher antibody respond if compared with antibody production in broiler serum post vaccinated with some commercially available broiler vaccines.

Introduction: Anseriform species such as Muscovy ducks, Mallard ducks and geese are commonly known to be susceptible to some of Newcastle disease virus (NDV) strains, while resistant to others. This study was designed to determine and compare the effect of XIVb strain of NDV on the haematological parameters of Muscovy ducks in relation to the local chickens. Methods: Forty experimental birds consisting of twenty Muscovy ducklings and twenty local chicks at five weeks of age were divided into four groups of 10 subjects each, designated as infected chickens (IC), control chickens (CC), infected ducklings (ID) and control ducklings (CD) and were inoculated orally with 107.8/ 0.1ml /bird as the embryo lethal dose (ELD50/ml) of the strain obtained from the National Veterinary Research Institute, Vom. The means of haematological parameters were used to determine the response of the birds in each group and were compared to their controls (at days 0, 3, 7, 10, 14, 21, 28, and 35). Results: The result showed reduction in some of the haematological parameters, such as RBC and PCV, MCV, HB concentration, MCH and leukocyte count of both the IC and ID. RBC was (1.71±0.26×1012/l) and (2.77±0.20×1012/l) in the IC and ID against their control groups (3.69±0.31×1012/l) and (3.71±0.31×1012/l) on day 7PI, respectively. The IC also showed significant (p < 0.05) lymphopenia on days 7, 10 and 21 than the CC while the ID showed significant (p < 0.05) lymphocytosis on days 14, 21, 28 and 35 than the CD. Significance: The haematological parameters of the local chickens are more affected when infected with XIVb strain of NDV than that of the Muscovy ducks.

Newcastle disease virus strains are velogenic, mesogenic, and lentogenic. This study aims to design a scoring system for lesions induced by different strains of Newcastle disease virus in chicken. Three experiments were conducted. In experiments 1 and 2, chickens were divided into infected and control groups. Infected groups of experiments 1 and 2 consisted of 6 and 24 specific pathogen-free (SPF) chickens, respectively. Control groups in experiments 1 and 2 consisted of 6 and 15 SPF chickens, respectively. In infected groups, infection was induced by intranasal administration of 10550% EID50/0.1 mL of velogenic Newcastle disease virus strain (vNDV). Infected chickens in experiment 1 were euthanised by cervical dislocation on days 3, 6, and 7 postinoculation (pi). Infected chickens in experiment 2 were euthanised at hours (hrs) 2, 4, 6, 12 and days 1, 2, 4, and 6 pi. Chickens of the control group in experiment 1 were euthanised on days 3 and 7 pi, whereas control group chickens in experiment 2 were euthanised on days 0, 1, 2, 4, and 6 pi. Then in experiment 3, 15 SPF chickens were divided into three groups; in the first group, 5 SPF chickens were infected with vNDV, in the second group, 5 SPF chickens were infected with lentogenic NDV (lNDV) (103.0EID50/0.1 mL), and the third group was kept without infection as a control group. Chickens were euthanised on day 5 pi. In all previous experiments, tissues of brain, trachea, lung, caecal tonsil, liver, kidney, spleen, heart, proventriculus, intestine, and thymus were collected, fixed in 10% buffered formalin, embedded in paraffin, and sectioned. HS staining was applied. Tissues were examined under light microscope and changes were recorded. A scoring system was designed for lesions induced by different strains of NDV and, accordingly, lesions were scored. The scoring system was found helpful in the evaluation of disease severity.

A study was undertaken for testing the comparative efficacy of two live vaccines produced in Bangladesh to control Newcastle disease (ND) in chickens. One of these vaccines named ‘baby chicks Ranikhet disease vaccine (BCRDV), a government vaccine produced by the Livestock Research Institute, Mohakhali, Dhaka, and the other named ‘Bangla-BCRDV®', a commercial vaccine produced recently by a pharmaceutical company. Both the vaccines are prepared using the ‘F' strain of Newcastle disease virus (NDV). Three hundred Fayoumi chicks distributed in 3 groups were used in this study. The results of this study revealed that, at the age of 49 days the survival rates of chicks belonged to BCRDV, Bangla-BCRDV® and control groups were 69, 11 and 18%, respectively. The survival rate of Fayoumi chicks in the BCRDV group was significantly higher than that of the two other groups (p <0.05). Conversely, almost similar survival rates of chicks were recorded in the control and Bangla-BCRDV® groups (p >0.05). At day-1, the haemagglutination inhibition (HI) titre to NDV of the chicks was log2 5.8 ± 0.79 (SEM). At day 35 the same HI titre was observed in the chicks of the BCRDV group, which was, 1 and 1.5 log (base 2) higher than the chicks of the control and Bangla-BCRDV® group, respectively. At day-49, HI titres to NDV ≥ log212 were recorded in the chicks of all the three groups that survived having challenged with velogenic NDV. There were no significant differences in weekly mean body-weights of the chicks in all the three groups until the week 8 when the mean bodyweight of the chicks was higher in the BCRDV group compared with the two others. These results indicted that the efficacy of BCRDV in Fayoumi chicks against ND was better than the Bangla-BCRDV®.Keywords: Baby chick ranikhet disease vaccine, Bangla baby chick ranikhet disease vaccine, Newcastle disease (ND), Newcastle disease virus (NDV), Newcastle disease vaccine (NDC), Fayoumi chicksDOI: http://dx.doi.org/10.3329/bjm.v23i2.876 Bangladesh J Microbiol, Volume 23, Number 2, December 2006, pp 125-129
