Question

Zara is suffering from cough and has bluish lips. Her mucus is mixed with blood. What is the biological name of the causative organism responsible for Zara’s condition?

Hint:

Always associate "bluish lips/finger nails" with Pneumonia rather than common cold in your exams.

Answer 1

Step 1: Understanding the Concept:
The clinical symptoms described—cough, bloody mucus, and cyanosis (bluish lips)—are severe indicators of Bacterial Pneumonia.

Step 2: Detailed Explanation:
In pneumonia, the alveoli (air sacs) of the lungs get filled with fluid, leading to severe problems in respiration.
The bluish color of the lips and finger nails is due to the lack of oxygen in the blood, a condition occurring in severe cases.
The most common pathogens causing this in humans are Streptococcus pneumoniae and Haemophilus influenzae.

Step 3: Final Answer:
The causative organism is Streptococcus pneumoniae.
