Invasion and multiplication of pathogenic microorganisms in the body is called an infection. When we are infected by pathogens we become sick, which means that our bodies stop functioning properly. Infectious agents, such as bacteria, a virus, fungi or protozoa cause communicable diseases.
SInce this term contains the root word pathogen, this means that it is associated with a virus of some sort. Microbe is a word used to refer to a microorganism that boosts decay or damage to a tissue. This means that a pathogenic microbe is a virus - causing bacteria. If you look at the link I have posted below, you can see that the word 'microbe' is included in the list.
