One key difference between bacteria and viruses is their structure and composition. Bacteria are single-celled organisms that have a cell wall and can live independently, while viruses are not considered living organisms and consist of genetic material wrapped in a protein coat. Additionally, bacteria can reproduce on their own through binary fission, while viruses require a host cell to replicate and spread. Another difference is that antibiotics are effective in treating bacterial infections, but they are not effective against viral infections.
