Bacterial Pneumonia & Respiratory Infection — NEET Biology
🔥 Predicted for NEET 2027Bacteria like Streptococcus pneumoniae and Haemophilus influenzae are responsible for the disease pneumonia in humans which infects the alveoli (air filled sacs) of the lungs. As a result of the infection, the alveoli get filled with fluid leading to severe problems in respiration. The symptoms of pneumonia include fever, chills, cough and headache. In severe cases, the lips and finger nails may turn gray to bluish in colour. A healthy person acquires the infection by inhaling the droplets/aerosols released by an infected person or even by sharing glasses and utensils with an infected person. Dysentery, plague, diphtheria, etc., are some of the other bacterial diseases in man.
Adjacent to a frequently-asked paragraph in the same chapter.
A patient shows recurrent high fever every 3–4 days due to rupture of RBCs, and later develops persistent cough with fluid-filled alveoli. Which combination of pathogens is most likely involved?
View solution & NCERT explanation
Correct answer: A — Plasmodium falciparum and Streptococcus pneumoniae
Plasmodium causes malarial fever due to haemozoin release every 3–4 days, while Streptococcus pneumoniae causes fluid-filled alveoli leading to pneumonia.
