Pneumonia is an infection that primarily affects the ____A______. The leading cause of pneumonia is a specific type of bacteria referred to as ____B____and ___C_____.

What is the most suitable combination of options to fill the blanks in the statement about pneumonia?

A–lungs, B–Streptococcus pneumoniae, C–Haemophilus influenzae

The correct answer is Option (2)- A–lungs, B–Streptococcus pneumoniae, C–Haemophilus influenzae.

Bacteria such as Streptococcus pneumoniae and Haemophilus influenzae are responsible for causing pneumonia, a disease that affects the air-filled sacs called alveoli in the lungs. When these bacteria infect the lungs, the alveoli become filled with fluid, leading to difficulties in breathing. Common symptoms of pneumonia include fever, chills, cough, and headache. In more severe cases, the lips and fingernails may appear bluish in color. Pneumonia can be transmitted to a healthy individual through inhalation of droplets or aerosols released by an infected person, as well as by sharing glasses and utensils.

Pneumonia is an infection of the lungs (A). The most common cause of pneumonia is a type of bacteria known as Streptococcus pneumoniae (B), also called pneumococcus. Another common bacterium that can cause pneumonia is Haemophilus influenzae (C).

These bacteria can infect the lungs and lead to inflammation, fluid accumulation, and respiratory symptoms associated with pneumonia. Streptococcus pneumoniae and Haemophilus influenzae are among the most common bacterial pathogens responsible for community-acquired pneumonia.
