These strains occur because of the phenomenon known as antigenic shift, in which humans are infected with avian influenza viruses or viruses that contain a combination of genes from human and ...

A new strain of bird flu has been detected on a duck farm in California. The World Organisation for Animal Health reported ...

The California duck farm's strain of H5N9 is different from those earlier cases because this time it is closely related to a ...

In 1999, the AFIP reported that after completely analyzing a critical gene from the 1918 influenza virus their researchers had determined that the 1918 virus apparently evolved in mammals ...

Experts say our cities have a valuable tool that can help us keep better tabs on the virus: sewage. While wastewater already ...

In the near future, gene silencing against influenza viruses may also be successfully applied in antiviral therapeutics. There are several bottlenecks in the successful application of gene ...

Public health officials have warned that new mutations of bird flu with human flu could have dangerous consequences.

The team found that animals that had the virus inoculated directly into their lungs became severely ill, whereas animals that ...

Is there a connection between bird flu and microRNA, the tiny bits of RNA which have different tasks in regulating genes and producing the body's building blocks? "MicroRNA is quite stable ...

"The Chinese poultry lineage may have experienced more vaccine-driven selection compared to other lineages," the researchers ...

In theory, if infected with avian and mammalian flu at the same time, flu genes could reassort inside the pig and create a highly pathogenic strain adapted for mammalian transmission. Additionally ...
