Question

Why are viruses always pathogens but not all bacteria?

Answer 1

Pathogens:

1. Pathogens are the microorganisms that live inside the cell of other organisms or use their machinery to sustain their life.
2. These pathogens can cause infection in the host cell.
3. Viruses cannot live independently, They need the host machinery to survive and thus are considered pathogens.
4. But bacteria can live independently on their own and gather resources for their survival.
5. Therefore, only some bacteria are considered pathogens whereas all viruses are considered pathogens.
