Bacteria and viruses share one similarity and one difference based on their reproduction. Bacteria are similar to viruses in that they both reproduce asexually. Binary fission is the asexual reproduction of bacteria to produce two identical cells whose DNA is identical to the DNA in the original bacteria. On the other hand, viruses reproduce by viral reproduction either in a lytic pathway or lysogenic pathway. In the lytic pathway, the virus enters and injects a host cell with DNA, forcing it to make viruses. The injected DNA can become inactive for some time until appropriate cellular events trigger its awakening.

They have no organelles as eukaryotes do. Coat proteins contain the virion and replication proteins in the virus while the bacteria has a membrane containing the organism as well as cell walls but neither subdivide internal functions. So both are asexual, single unit organisms that have protective coats.

They both adapt to extremes eukaryotes haven't.
Archaebacteria include the thermophiles & the halophiles. Even they have viral infections.

There are similar cellular responses to bacterial and viral invasion.http://www.pnas.org/cgi/content/full/101/3/695
Toll like Receptor (TLR) signaling is induced by both bacterial and viral ligands in infections.

Horizontal gene transference is common in both virii and bacteria. This is probably why cellular response overlaps against bacterial & viral infections.

Neither are, usually, capable of myristoylation, the N-terminal attachment of a myristoyl lipid anchor to a glycine residue applied by N-myristoyltransferase (NMT). Their proteins are consequently processed by NMTs of their eukaryotic hosts.

Both can cause disease and both offer benefits, although with fewer benefits from the virus because they are all based on very modern medical technology. Medical applications using virii: Vaccinations, gene therapy

Modern uses of bacteria include restriction enzymes in transgenics. So both can be useful in modern medicene.

Besides their reproduction, they are both microscopic and attack organs and tissues in your body. Some only attack specific areas such as the lungs or bowels. They both have the potential to mutate into more virulent forms. They both suck except there are certain bacteria that your body depends on for proper function, like digestive bacteria.

Small. Contain DNA and protein.
