Question 6 (What are the two primary types of bacteria?)
The two primary types of bacteria are typically non - pathogenic (harmless or beneficial) and pathogenic (harmful, cause disease). Another common classification is based on shape like Cocci (spherical), Bacilli (rod - shaped), but for primary types in terms of their effect on hosts, non - pathogenic and pathogenic are key.
Non - pathogenic bacteria do not cause disease. Some examples are bacteria in our gut that help with digestion. They can be beneficial or at least harmless.
Cocci bacteria have a spherical or round shape. They can exist as single cells, in pairs (diplococci), chains (streptococci), or clusters (staphylococci), but the basic shape is spherical.
