Bacterial infections are diseases that can affect your skin, lungs, brain, blood and other parts of your body. You get them from single-celled organisms multiplying or releasing toxins in your body. Common bacterial diseases include UTIs, food poisoning, STIs and some skin, sinus and ear infections.
Bacteria are single-celled microorganisms that lack a nuclear membrane, are metabolically active and divide by binary fission. Medically they are a major cause of disease. Superficially, bacteria appear to be relatively simple forms of life; in fact, they are sophisticated and highly adaptable.

May 31, 2022 · A bacterial disease is an illness caused by a bacterial infection. Although most bacteria are harmless or even helpful to you, disease-causing bacteria can cause a variety of health problems. This article provides a brief overview of bacteria and bacterial diseases, their symptoms, how bacteria spread, and more.
Pathogens are microorganisms that can cause disease. They can reproduce quickly in your body and give off poisons (toxins) that can cause infection. Harmful bacteria examples include: Streptococcus: Bacteria that cause strep throat. Staphylococcus: Bacteria that cause staph infections. Escherichia coli: Bacteria that cause E. coli infections.
Bacteria cause disease by secreting or excreting toxins (as in botulism), by producing toxins internally, which are released when the bacteria disintegrate (as in typhoid), or by inducing sensitivity to their antigenic properties (as in tuberculosis).
