Bacteria and viruses - we hear about them almost constantly on TV, on the radio and in the news. But what is the difference between the two dreaded pathogens? We cannot see either pathogen with the naked eye. But the differences are fundamental. We explain the differences in non-medical terms. If in doubt, please consult your doctor.
What are the differences between bacteria and viruses?
The only thing most people know is that they make you sick. But that's about it. But how else are they different? Which is more dangerous and how are they treated? The most important aspects for distinguishing between bacteria and viruses are listed below.
The difference in size
The size of bacteria and viruses is the most important factor when it comes to distinguishing between the two. Bacteria are much larger. Up to 100 times. For this reason, bacteria can be identified using a light microscope. They have a diameter of about half a micrometer to one micrometer. Viruses can only be seen and identified using an electron microscope.
The structure
Viruses have a much simpler structure. While bacteria are structured with a cell wall, ribosomes and cytoplasm, as well as a cell nucleus, viruses only have a protein wall in which a DNA, i.e. a certain genetic material, can be found.
The proliferation
Compared to bacteria, viruses need a host. "Quick question: What is the difference between viruses and bacteria?" read more
