Infection of poultry with chicken anemia virus (CAV) is implicated in several field problems in broiler flocks due to the immunosuppression generated and, consequently, the increased susceptibility to secondary infections. Recently, we have reported an increased occurrence of clinical cases caused by CAV strains distantly related to those commonly used for vaccination. In order to understand th...

Avian influenza virus A/chicken/Jiangsu/1001/2013(H5N2) was identified from a healthy chicken in an eastern China poultry market. Whole-genome analysis demonstrated that the H5N2 virus originated from a reassortance between a previous A/chicken/Hebei/1102/2010(H5N2) virus and an endemic H5N1 virus. The results indicated that continuing reassortance of H5N2 has been occurring in domestic poultry...

BACKGROUND Chicken Mx belongs to the Mx family of interferon-induced dynamin-like GTPases, which in some species possess potent antiviral properties. Conflicting data exist for the antiviral capability of chicken Mx. Reports of anti-influenza activity of alleles encoding an Asn631 polymorphism have not been supported by subsequent studies. The normal cytoplasmic localisation of chicken Mx may i...

  Egg drop syndrome (EDS) is caused by a hemagglutinating adenovirus which has become a major cause of lost egg production and sever economic losses in breeder and layer chicken flocks throughout the world. A PCR assay was optimized for detection of EDS virus in inoculated allantoic fluids (AFs) of duck and chicken emberyonated eggs. Two strains of EDS viruses were propagated in allantoic cavit...

INTRODUCTION Anemia affects around 38.2% and 22% of pregnant women at a global and national level respectively. In developing countries, women start pregnancy with already depleted body stores of iron and other vitamins with significant variation of anemia within and between regions. OBJECTIVE To identify the determinants of anemia among pregnant mothers attending antenatal care in Dessie tow...

chicken infectious anaemia is a viral disease in young chickens which characterized by aplastic anaemia and immunosuppression. between january 2004 and july 2005, an unusual hemorrhage in subcutaneous and intramuscular tissues of broiler chickens at slaughter houses of mashhad, isfahan and tehran provinces were occurred. postmortem examination revealed severe hemorrhages in the wings and muscle...

Background: Non-ionic surfactant, Tween-80 (TW80) is commonly used for drug delivery due to its effect on the cell membrane permeation. The change in permeability can also increase viral infectivity in cells. This study was undertaken to improve upon Newcastle disease virus (NDV) titer cultivated with embryonic chicken eggs. Methods: The toxicity of TW80 was investigated against chicken embryo...
