Introduction:
Diseases can be caused by various factors such as bacteria, viruses, fungi, and parasites. Each of these has different signs and symptoms and requires different treatments. In this question, we are asked to identify which disease is caused by bacteria.

Explanation:
Among the given options, Tuberculosis is the only disease that is caused by bacteria. Tuberculosis (TB) is a bacterial infection caused by Mycobacterium tuberculosis. It primarily affects the lungs but can also affect other parts of the body such as the kidneys, spine, and brain.

The bacteria spread through the air when an infected person coughs, sneezes, or talks. The symptoms of TB include coughing that lasts for more than three weeks, chest pain, coughing up blood, unintentional weight loss, fatigue, fever, and night sweats.

TB can be treated with antibiotics, but the treatment can last for several months. It is important to complete the full course of treatment to ensure that all the bacteria are eliminated from the body and to prevent the development of drug-resistant strains of TB.
