Answer: A. Streptococcus pneumoniae
-
Streptococcus pneumoniae (pneumococcus) is a Gram-positive bacterium that is responsible for the majority of community-acquired pneumonia
-
S. pneumoniae is alpha-hemolytic, meaning that it can break down red blood cells through the production of hydrogen peroxide (H2O2). The production of H2O2 by the bacterial infection can also cause damage to DNA, and kill cells within the lungs.
- Pneumococcal pneumonia causes fever and chills, coughs, difficulty breathing, and chest pain. If the infection spreads to the brain and spinal cord, it can cause pneumococcal meningitis,
