Mallard or chicken? Comparing the isolation of avian influenza A viruses in embryonated Mallard and chicken eggs
BACKGROUND To date, the most efficient and robust method for isolating avian influenza A viruses (IAVs) is using embryonated chicken eggs (ECEs). It is known that low-pathogenic avian IAVs undergo rapid genetic changes when introduced to poultry holdings, but the factors driving mutagenesis are not well understood. Despite this, there is limited data on the effects of the standard method of vir...
متن کاملThermal inactivation of avian influenza and Newcastle disease viruses in chicken meat.
Avian influenza viruses (AIV) and Newcastle disease viruses (NDV) of high pathogenicity cause severe systemic disease with high mortality in chickens and can be isolated from the meat of infected chickens. Although AIV and NDV strains of low pathogenicity are typically not present in chicken meat, virus particles in respiratory secretions or feces are possible sources of carcass contamination. ...
متن کاملEvidence of Infection with H4 and H11 Avian Influenza Viruses among Lebanese Chicken Growers
Human infections with H5, H7, and H9 avian influenza viruses are well documented. Exposure to poultry is the most important risk factor for humans becoming infected with these viruses. Data on human infection with other low pathogenicity avian influenza viruses is sparse but suggests that such infections may occur. Lebanon is a Mediterranean country lying under two major migratory birds flyways...
متن کاملIntracellular restriction on the growth of induced subgroup E avian type C viruses in chicken cells.
Subgroup E avian type C viruses produced by bromodeoxyuridine-treated 100 X 7, line 7, or line C chicken cells were restricted in their intracellular growth on K28 chicken cells but not on line 15 chicken cells. Cells from embryos of line 15 chickens bred with K28 chickens did not restrict the growth of the subgroup E induced leukosis viruses (ILVs). This result indicates that the phenotype for...
متن کاملMultiple group-specific antigen components of avian tumor viruses detected with chicken and hamster sera.
Multiple group-specific (gs) components of the avian leukosis-sarcoma viruses were detected by immunodiffusion (Ouchterlony) tests with sera from hamsters bearing tumors induced by sarcoma viruses and with sera from adult chickens immunized with avian sarcoma or leukosis viruses. Immune hamster sera detected up to four components, whereas chicken sera detected at least one. The hamster and chic...
