Question

Pneumonia is caused by

• A. Streptococcus pneumonia
• B. Haemophilus influenzae
• C. Both (A) & (B)
• D. None

Answer 1

The Correct Option is C

Pneumonia is an infection that inflames the air sacs in one or both lungs. The air sacs may fill with fluid or pus (purulent material), causing cough with phlegm or pus, fever, chills, and difficulty breathing.

Pneumonia can be caused by a variety of organisms, including bacteria, viruses, and fungi.

Looking at the specific options provided: 

• Streptococcus pneumoniae: This bacterium, also known as pneumococcus, is one of the most common causes of community-acquired bacterial pneumonia in adults and children.
• Haemophilus influenzae: This bacterium (specifically type b, before widespread vaccination, and now more commonly non-typeable strains) is another significant cause of bacterial pneumonia, particularly in young children and adults with underlying health conditions like COPD.

Since both Streptococcus pneumoniae and Haemophilus influenzae are well-established bacterial causes of pneumonia, the correct answer encompasses both.

Therefore, pneumonia can be caused by Both (A) & (B).

Answer 2

Pneumonia can be caused by various bacteria, including:

• Streptococcus pneumoniae: This is a common bacterial pathogen responsible for causing pneumonia, especially in young children, elderly adults, and individuals with weakened immune systems.
• Haemophilus influenzae: This bacterium can also cause pneumonia, particularly in people with chronic lung conditions or weakened immune systems.

Since both Streptococcus pneumoniae and Haemophilus influenzae are known to cause pneumonia, the correct answer is:

The correct answer is (C) : Both (A) & (B).
