(D) The occurrence of the œcrisis in pneumococcal pneumonia generally corresponds to the time of maximum leukocytosis.

(E) Hypogammaglobulinemia is an important factor contributing to the unfavorable prognosis for pneumococcal
pneumonia in alcoholic persons.

The answer is A.
The incidence of pneumonococal bacteremia drops after 2 years of age but rises again in those over age 55.

All splenectomized patients, even those without underlying disease, should receive pneumococcal vaccine.

The œcrisis in pneumococcal pneumonia ordinarily corresponds to the appearance of type-specific antibodies, not maximum leukocytosis.

Alcoholic persons who develop pneumococcal pneumonia have a poor prognosis for several
reasons: their tendency to aspirate pharyngeal flora, poor functioning of bronchial clearance
mechanisms, and impaired leukocyte response (hypogammaglobulinemia generally is not
a contributing factor).

Pneumococcal pneumonia frequently precedes pneumococcal meningitis.

Pneumococci cause pharyngitis extremely rarely.
