Truncation of the NS1 protein converts a low pathogenic avian influenza virus into a strong interferon inducer in duck cells [PDF]
The NS1 protein of influenza A viruses is known as a nonessential virulence factor inhibiting type I interferon (IFN) production in mammals and in chicken cells. Whether NS1 inhibits the induction of type I IFNs in duck cells is currently unknown.

Construction and characterization of H5N1-recombinant fowlpox viruses co-expressing host cytokines [PDF]
Possessing a large double stranded DNA genome up to 300 kb, fowlpox virus (FWPV) has been developed to express avian influenza virus (AIV) antigens since the late 1980s. A more advanced approach would be to coexpress host cytokines from such recombinants.

The Transcriptional Landscape of Marek’s Disease Virus in Primary Chicken B Cells Reveals Novel Splice Variants and Genes [PDF]
Marek’s disease virus (MDV) is an oncogenic alphaherpesvirus that infects chickens and poses a serious threat to poultry health. In infected animals, MDV efficiently replicates in B cells in various lymphoid organs.

Avian Adenoviruses Infections with Special Attention to Inclusion Body Hepatitis/ Hydropericardium Syndrome and Egg Drop Syndrome [PDF]
The first avian adenovirus (AAV) associated with clinical disease was isolated from an outbreak of respiratory disease in quail in 1950 (Olson, 1950). Since that time, AAVs have been found in all types and breeds of chickens and from a variety of other ...

The cellular localization of avian influenza virus PB1-F2 protein alters the magnitude of IFN2 promoter and NFκB-dependent promoter antagonism in chicken cells. [PDF]
The accessory protein, PB1-F2, of influenza A virus (IAV) functions in a chicken host to prolong infectious virus shedding and thus the transmission window.

Isolation and analysis of a very virulent Marek’s disease virus strain in China [PDF]
BACKGROUND: A severe MD was broken out at a farm in Shandong, China, despite FC126 vaccination of the chickens at 1-day-old. The mortality of the flocks reached up to 38.3%.
