Bacteria are intercellular organisms (i.e. they live in-between cells); whereas viruses are intracellular organisms (they infiltrate the host cell and live inside the cell). They change the host cell's genetic material from its normal function to producing the virus itself.
Bacteria, viruses and protists can be compared and contrasted according to their structure, reproduction and effects. Although both bacteria and viruses are similar in their small shape, bacteria consist of one cell, while viruses are not considered cells, and protists may be unicellular (one celled) or multicellular.Both bacteria and viruses reproduce asexually, protists both asexually and sexually.owever, bacteria reproduce by binary fission, whereas viruses reproduce by replication. While bacteria, viruses and protists are similar in that they both cause diseases, bacteria and protists can have some helpful effects.
