Determination of the seroprevalence of Newcastle disease virus (Avian paramyxovirus type 1) in Zambian backyard chicken flocks
… objectives of this study were to determine the Newcastle disease virus (NDV) antibody titres from the chicken sera collected from various districts and provinces of Zambia and to determine the seroprevalence of ND in Zambian backyard chickens. Results showed that 73.9 % of the birds sampled …

Alloantigen systems and resistance to Eimeria tenella and Newcastle-B1 in chickens selected for response to sheep erythrocytes
… involved in resistance to Eimeria tenella and Newcastle disease virus (NDV). Routes of administration were intravenous for SRBC antigen and intranasal for NDV. Chicks were exposed to E. tenella either through a natural challenge via the litter or a controlled oral administration. Differences …

Virus-Based Nanoparticles for Tumor Selective Targeting and Oncolysis
… targeting of a broad spectrum of malignancies. Newcastle disease virus (NDV), an avian paramyxovirus, is naturally tumor-selective and inherently oncolytic. Our approach is to develop NDV-based nanoparticles (VBNP) for oncolytic virotherapy. VBNPs are non-infectious and non-replicating and are …

Evaluation of the potential functions of Avian paramyxovirus Accessory proteins
Avian paramyxoviruses (APMVs) consist of twelve distinct serotypes (APMV-1 to -12) isolated from a wide variety of domestic and wild birds. APMV-1/Newcastle disease virus (NDV) is the most characterized and globally important avian pathogen, because of the huge economic loss associated with the …

Incubation temperature and post-hatch stress effects on immune parameters, immune system development, and performance in commercial broilers
… were administered vaccinations for Marek's disease virus (MDV) at embryonic day (ED) 18, Newcastle disease virus (NDV) at hatch, the combination of MDV+NDV, or no vaccine (control). There were 16 resulting experimental groups: LH-Control, LH-MDV, LH-NDV, LH-MDV+NDV, LS-Control, LS-MDV, …

Antiviral potential of hadjod (Cissus quadrangularis) extract against newcastle disease virus.
Newcastle Disease (ND) is a highly contagious viral disease that has a devastating global impact on the poultry industry. Ethanol (EtOH) crude extract from the stem of Cissus quadrangularis (CQL) was prepared and tested against Newcastle Disease Virus (NDV) replication using an in- ovo assay in …

Production of plant-expressed virus-like particle vaccines against infectious bronchitis coronavirus and vaccine efficacy in chickens
Infectious Bronchitis Virus (or IBV) is the root cause of extremely infectious respiratory disease that occurs in chickens. It has a high mutation rate that causes the emergence of multiple variants that are difficult to control, leading to major worldwide economic losses to the poultry industry. …

Untersuchung der Typ I Interferon-Signaltransduktion in HPV-Onkogen immortalisierten Keratinozyten
Humanes Papillomvirus (HPV)16 gehört zu der Gruppe der �high risk� Viren, die mit der Entstehung der Zervixkarzinome assoziiert werden. Im Verlauf der HPV-vermittelten Tumorigenese wird die Kommunikation infizierter Zellen mit dem Immunsystem verändert. In der vorliegenden Arbeit wird zum ersten …

Targeted Oncolytic Virotherapy Using Newcastle Disease Virus Against Prostate Cancer
… including stem cells are imperative. Oncolytic virus (OV) therapy is a novel approach that overcomes the limitations posed by radiation and chemotherapy. Oncolytic virotherapy of cancer is based on the use of replication competent, tumor selective viruses with limited toxicity. Newcastle Disease …

DEVELOPMENT OF AVIAN PARAMYXOVIRUS VECTORED VACCINES
Avian Avulaviruses (formerly Avian Paramyxoviruses, APMV) are important pathogens of avian species and have been used as viral vectors for more than two decades. Among all APMVs, Newcastle disease virus (NDV or APMV-1) has been most extensively used as a vaccine vector for protection against avian …

Sterility and immunogenicity of gamma-irradiated respiratory viruses
… sterilising doses that is highly applicable to viruses and bacteria. Our research group has developed a whole-inactivated influenza A virus (IAV) vaccine using γ-radiation (γ-Flu). IAV presents a constant pandemic threat due to the mutagenic nature of the virus and the inadequacy of current …

Challenge studies in chickens to evaluate the efficacy of commercial Newcastle disease vaccines against the strains of Newcastle disease virus prevalent in South Africa since 2002
… poultry industry has experienced outbreaks of Newcastle disease (ND) caused by a newly introduced virus (NDV) strain belonging to lineage 5d/VIId (“goose paramyxovirus” - GPMV). Control of the disease has proved difficult with commercially available vaccines appearing ineffective. In the first …
