What is the difference between a bacteriophage and a virus?
Question
The other day, someone in class asked about the difference between a virus and a bacteriophage, and it really got me thinking. Both are technically viruses, but they target different organisms and operate in unique ways. I checked a virology book and found this clear explanation comparing their structure, life cycle, and significance in medicine and research.

Key Differences
In summary, while bacteriophages are indeed viruses, they represent a specialized category with unique characteristics adapted to infecting bacterial hosts. Their distinctive structures, infection mechanisms, and life cycles set them apart from viruses that infect eukaryotic cells, making the distinction between “bacteriophage” and “virus” useful in scientific and medical contexts, even though it’s technically a distinction between a subset and its larger category.
