Bacteria are single-celled microorganisms that can cause a variety of diseases. Here are 10 examples:
-
Tuberculosis (TB): Caused by Mycobacterium tuberculosis, TB most often affects the lungs but can spread to other organs. WHO Fact Sheet on Tuberculosis provides more information.
-
Pneumonia: This lung infection can be caused by various bacteria, including Streptococcus pneumoniae. Symptoms include cough, fever, and shortness of breath.
-
Meningitis: Several bacteria can cause meningitis, a serious infection of the membranes surrounding the brain and spinal cord. Neisseria meningitidis is a common cause. The CDC's information on Meningococcal Disease details this further.
-
Urinary Tract Infections (UTIs): Escherichia coli (E. coli) is a frequent culprit in UTIs, which can cause pain, burning during urination, and frequent urges to urinate.
-
Strep Throat: This painful throat infection is caused by Streptococcus pyogenes.
-
Wound Infections: Many bacteria can infect wounds, leading to swelling, redness, pain, and pus.
-
Tetanus: Caused by Clostridium tetani, tetanus is a serious illness characterized by muscle spasms and stiffness.
-
Salmonella: This bacterium often causes food poisoning, leading to diarrhea, vomiting, and abdominal cramps.
-
Legionnaires' disease: This severe form of pneumonia is caused by Legionella pneumophila, often found in water systems.
-
Whooping cough (Pertussis): This highly contagious respiratory illness is caused by Bordetella pertussis.
This list is not exhaustive, as many other diseases are caused by bacteria. It's important to note that prompt medical attention is crucial for effective treatment of bacterial infections. Many bacterial infections are treatable with antibiotics.
