Thus, the virus cannot grow or spread to other cells.

These viruses grow best at temperatures of about 91 degrees, that perfect body temperature right inside the human nose.

As the virus grows inside a cell, crystalloids, or bricks, appear at the center.

In a way," he continued, "it's a good thing that the virus grows so quickly.

If the virus grows in the culture, it will cause changes in the cells that can be seen under a microscope.

Developing a vaccine has been difficult because the virus will not grow in cell culture and until recently it was not known why.

This method however is relatively slow and not all viruses will grow on cell sheets.

Bacteria or viruses can grow in this fluid and form an ear infection.

The virus grows slowly and without symptoms for twenty or more years after entering the system.

The virus grew in only a few established cell lines, indicating a restricted host range.
