Question:
Why is it important that we think of these categories of infectious agents?
Answer:
Members of each one of these groups – viruses, bacteria, and so on – have many biological characteristics in common. these categories are important factors in deciding what kind of treatment to use. It implies many important life processes are similar in the bacteria group but are not shared with the virus group. As a result, drugs that block one of these life processes in one member of the group is likely to be effective against many other members of the group. But the same drug will not work against a microbe belonging to a different group.
