What is the difference between a bacterial infection and a viral infection?

Different germ types: Bacteria are larger germs, and they can live in a broth or culture dish in a lab, or sometimes in soup, egg salad, etc... Treatment is with "antibiotics", but the exact term should be "antibacterials". Viruses are much smaller, and cannot reproduce on their own. Viruses have to invade other cells, such as our own cells, and use those cells to make new viruses. Anti-virals are used to stop viruses.

Different treatment: Bacterial infections usually responds to antibiotics however the viral infection does not. The presentations and the course are different.
