Microbiology

Microbiology is a branch of biology dealing with the study of microscopic life. The study includes the study of virii, bacteria, fungi, and parasites to name a few. Some of these organisms can cause illnesses in humans, and some are necessary for life to continue, such as the bacteria in the colon which aid in digestion of food.

pathogenic microbes come in two different types. Opportunistic and non-opportunisitic. Opportunisitic ones are found naturally in the body and only become pathogenic when there are too many of them.

However, non-opportunisitic pathogenic microbes, simply cause disease.
