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.

Bacterial infections are any illness or condition caused by bacterial growth or poisons (toxins). You can get sick from getting harmful bacteria in your skin, gut (GI tract), lungs, heart, brain, blood or anywhere else in your body. Harmful bacteria from the environment, an infected person or animal, a bug bite or something contaminated (like food,...
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...
Bacteria can cause many types of infections, depending on how you’re exposed and what part of your body it infects. Some common types of bacterial infections include: 1. Food poisoning (gastroenteritis). 2. Some skin,ear or sinus infections. 3. Some sexually transmitted infections (STIs). 4. Bacterial pneumonia. 5. Most urinary tract infections (UT...
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 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).

May 31, 2022 · 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.
The most common causes are viruses, bacteria, fungi and parasites. Infectious diseases usually spread from person to person, through contaminated food or water and through bug bites. Some infectious diseases are minor and some are very serious.
Health Library / Articles / Bacteria are tiny, single-celled living organisms. There are millions of different types of bacteria. Many can be found in and on your body and are beneficial to you. These bacteria make up your microbiome, which keeps your body healthy. Other bacteria can make you sick.
Nov 21, 2022 · Our findings show that more than half of all global bacterial deaths in 2019 were due to five bacterial pathogens: Staphylococcus aureus, Escherichia coli, Streptococcus pneumoniae, Klebsiella pneumoniae, and Pseudomonas aeruginosa.
