Disease caused by bacteria:
- Tuberculosis
- Diphtheria
- Pneumonia

Disease NOT caused by bacteria:
- Measles

Explanation:
Measles:
Measles is a highly contagious viral infection caused by the measles virus. It is not caused by bacteria but by the paramyxovirus family, specifically the measles virus. Measles is characterized by symptoms such as fever, cough, runny nose, red eyes, and a rash that spreads all over the body. It can lead to complications such as pneumonia, encephalitis (brain inflammation), and even death in severe cases.

Tuberculosis:
Tuberculosis (TB) is caused by the bacteria Mycobacterium tuberculosis. It primarily affects the lungs but can also affect other parts of the body. TB spreads through the air when an infected person coughs or sneezes, releasing bacteria-containing droplets. Symptoms of TB include coughing, chest pain, fatigue, weight loss, and fever.

Diphtheria:
Diphtheria is a bacterial infection caused by Corynebacterium diphtheriae. It spreads through respiratory droplets or direct contact with an infected person or contaminated objects. Diphtheria primarily affects the throat and can lead to severe breathing difficulties. Other symptoms include a thick grayish coating in the throat, fever, and swollen lymph nodes.

Pneumonia:
Pneumonia can be caused by various bacteria, including Streptococcus pneumoniae, Haemophilus influenzae, and Legionella pneumophila, among others. It is an infection that inflames the air sacs in one or both lungs, leading to symptoms such as cough, chest pain, fever, and difficulty breathing. Pneumonia can be acquired in community settings or in healthcare settings.

In conclusion, measles is the disease that is not caused by bacteria. It is a viral infection caused by the measles virus. The other three diseases listed (tuberculosis, diphtheria, and pneumonia) are caused by bacteria.
