Evolution of a deadly virus

Infections caused by the mosquito-borne eastern equine encephalitis virus (EEEV) are severe and have high mortality rates for horses—90 percent—and humans—33 percent, with significant brain damage in most human survivors.

Mutant protein sheds lights on viral propagation

Some genetic mutations can cause a virus to flourish. Others make the virus wither away, unable to function normally and reproduce. Yet other genetic mutations only show their hand under certain conditions.

Research shows some viruses can infect even after major mutations

Portland State University researchers have found that only about half the genes in a specific virus affecting single cell organisms is needed to infect a host. This means the virus can undergo major mutations without losing ...

Researchers crack the code of a deadly virus

Venezuelan equine encephalitis virus (VEEV) is an unforgiving killer of horses, donkeys and zebras, resulting in mortality as high as 80 percent of infected animals. It causes rapid, catastrophic swelling of the brain and ...
