Living, single-celled organisms that can reproduce on their own cause bacterial infections. Only a few types of bacteria cause illness in people. An organism that’s not made up of cells causes viral infections. Viruses always need to infect humans or other living things to create more copies of itself. Antibiotics can treat most bacterial infection...

There are many bacterial infections that aren’t usually serious or can be treated easily with antibiotics. Impetigo and boils are examples. However, any bacterial infection that gets deep into your body, like in your blood, heart, lungs or brain, can be life-threatening.
Bacterial infections can spread through droplets or dust in the air, direct or indirect contact, a vector (like a tick or mosquito) or contaminated food or water (vehicular).
Anyone can get a bacterial disease, and most of us will at some point in our lives. You’re at higher risk for getting an infection if you have: 1. Diabetes. 2. A weakened immune system (due to HIV/AIDS, cancer, cancer treatments or immunosuppressive medications). 3. An open wound. 4. Had surgery recently.
Bacteria can hurt your body either when they reproduce or by releasing poisons (toxins) that damage your cells. Infections that only affect the surface of your skin or mucous membranes (like your throat or intestines) aren’t usually serious, but sometimes, bacteria can spread in your body and cause life-threatening illnesses. If bacteria gets into ...
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.
