Bacteria are different from viruses. Viruses are much smaller. Viruses are unique in that they have either DNA or RNA. Hence they are classified as DNA viruses and RNA viruses.
Bacteria can multiply on their own but viruses need a living host.
Bacteria can be killed by antibiotics, but viruses can't. If you isolate a sample of the "substance" and expose it to antibiotics and it dies then you have a bacteria, but if it lives you have a virus. Keep in mind that when isolating yoru sample you must keep it within a living host. If you don't and it is a virus it will die with or without antibiotics. It is not wise to expose your sample to too many tests at one time because you don't have certainty as to which gave you the result.
A pathogenic bacterium is alive while a virus is not.
Bacteria has both DNA and RNA where as Virus has either DNA or RNA
Bacteria are not dependent on a host. :)
It is not. HIV is a virus. It has a completely different make-up from a bacteria. The most important difference between a bacteria and a virus is that a virus does not have the ability to replicate on its own. It needs a host, another cell, to reproduce, unlike bacteria which can reproduce on their own.
Viruses are (debatably) not alive while bacteria are; meaning they are smaller and require a living host to survive. Bacteria are killed with antibiotics, but viruses are not.
The only difference between viral and bacterial encephalitis is what causes it. They are exactly the same condition except one is started via a virus and one is started by a bacteria.
A virus runs in a thread, as do all programs. The difference between a generic thread and a virus is that the thread may not be harmful, while the virus generally is.
Bacteria are living cells -- cell membrane and all that cell stuff. A virus doesn't own it's own cell; it invades a cell and takes over, using the host cell to make more viruses.
The difference between a common animal virus and a retrovirus is that a retrovirus only contains RNA while a common animal virus will have DNA or RNA.

Smallpox was a virus.
