infecting

Some have now been seen in viruses infecting people, but none of those appear to have transmitted onward.

In addition to diagnostics, the NanoGripper could have applications in preventive medicine by blocking viruses from entering and infecting cells, Wang said.

Microbiologists say a broad ban would be destructive, sweeping up much routine virology research and hindering efforts to understand whether the H5N1 virus infecting U.S. cows will jump to humans.

They screened existing AAVs to find what was suitable for amphibians and optimized the infecting strategy eventually developing a "how-to guide" for frogs and newts.

Since April, 55 H5N1 cases have been reported in humans, and all but three have occurred in farmworkers in close contact with dairy cows or poultry, which the virus is infecting in droves.
