Question

What is a bacterial disease?

Answer 1

Bacterial diseases include any type of illness or disease caused by bacteria, a type of microbe. Microbes are tiny organisms that cannot be seen without a microscope and include viruses, fungi, and some parasites as well as bacteria. The vast majority of bacteria do not cause disease, and many bacteria are actually helpful and even necessary to good health. Millions of bacteria normally live on the skin and in the intestines and can also be found on the genitalia. Bacterial diseases result when the harmful bacteria get into an area of the body that is normally sterile, such as the bladder, or when they crowd out the helpful bacteria in places such as the intestines.
