Which of the Following Does NOT Explain Why a Patient

Which of the following does NOT explain why a patient with Klebsiella pneumonia is more likely to die than one with pneumococcal pneumonia?

A) Treatment options for Klebsiella pneumonia are limited because the causative agent is resistant to many antibiotics. Pneumococcal pneumonia can be treated with antibiotics such as penicillin.
B) The causative agent of Klebsiella pneumonia is Gram-negative and may cause septic shock. Streptococcus pneumoniae is a Gram-positive bacterium so does not have endotoxin.
C) The most severe types of Pneumococcal pneumonia can be prevented with the PPSV23 vaccine. There is no vaccine that protects against Klebsiella pneumonia.
D) Klebsiella pneumoniae causes lung abscesses which may result in the death of the patient. Pneumococcal pneumonia does not result in permanent lung damage.
E) All of these statements explain why Klebsiella pneumonia is more frequently fatal than pneumococcal pneumonia.
