He did not respond to questions or blink to visual threat; however, brainstem reflexes were intact, and he withdrew both arms and both legs from painful stimuli. A lumbar puncture was performed and showed 2083 nucleated cells per cubic millimeter (91% neutrophils), as well as a glucose level of 87 mg per deciliter (reference range, 40 to 70), and a protein level of 477 mg per deciliter (reference range, 10 to 45). A Wright–Giemsa stain of the cerebrospinal fluid was performed. Which one of the following organisms caused this presentation?
