Pathogenic Streptococcus pneumoniae produce a polysaccharide capsule that helps them evade phagocytosis by host phagocytes, allowing them to multiply, resulting in pneumonia. S. pneumoniae that lack the capsule do not cause disease as they are readily destroyed by host phagocytes. When a mixture of living nonencapsulated and heat-killed encapsulated S. pneumoniae are injected into a mouse, the mouse dies, and living capsulated bacteria can subsequently be isolated from the mouse. Which of the following best explains this result?
