                                                          There are a lot of differences of bacteria and virus. Bacteria has a nucleus while virus has none. Not all bacteria causes disease while virus always causes disease. Bacteria can be eliminated by anti-biotic while virus can be eliminated by anti-viral medicines. And bacteria is much larger than the virus, in size.
