Epidemiology-driven approaches to surveillance in HPAI-vaccinated poultry flocks aiming to demonstrate freedom from circulating HPAIV
Incursion pressure of high pathogenicity avian influenza viruses (HPAIV) by secondary spread among poultry holdings and/or from infected migratory wild bird populations increases worldwide. Vaccination as an additional layer of protection of poultry holdings using appropriately matched vaccines...
The rise of fowl adenovirus-associated diseases in Asia
Fowl adenovirus type 1-associated disease such as inclusion body hepatitis (IBH) and hepatitis-hydropericardium syndrome (HHS) were initially described in the 1960s in the United States and since then FAdV has been found widely distributed throughout the world. FAdVs are grouped...
Molecular and Pathotypic Characterization of Fowl Adenovirus Associated with Inclusion Body Hepatitis in...
Inclusion body hepatitis (IBH) is a disease of chickens characterized by acute mortality with severe anemia caused by fowl adenoviruses (FAdV). IBH is one of the most important re-emerging diseases world-wide. In India earlier IBH/ Hydropericardium Syndrome (HPS)...
Nomenclature updates resulting from the evolution of avian influenza A(H5) virus clades 2.1.3.2a, 2.2.1, and...
The divergence of the hemagglutinin gene of A/goose/Guangdong/1/1996-lineage H5N1 viruses during 2011 and 2012 (807 new sequences collected through December 31, 2012) was analyzed by phylogenic and p-distance methods to define new clades using the...
Antibody Titer Has Positive Predictive Value for Vaccine Protection against Challenge with Natural Antigenic-Drift Variants...
Vaccines are used in integrated control strategies to protect poultry against H5N1 high-pathogenicity avian influenza (HPAI). H5N1 HPAI was first reported in Indonesia in 2003, and vaccination was initiated in 2004, but reports of vaccine failures began to...
