Textbook Question
Chapter 46, Problem 1CA
A 45-year-old man was admitted to the hospital with chest and back pain. On examination, his chest was dull to percussion. A chest X-ray film showed lower-left-lung infiltrates. A sputum culture revealed alpha-hemolytic, gram-positive, catalase-negative cocci that were inhibited by optochin. The bacteria produced acid from lactose. Use Appendix H to identify the species of this bacterium.
