For each patient described, select the microorganism most likely to have caused the illness.
165. A 7-year-old child has a high fever and a sore throat. There is pharyngeal redness, a swollen right tonsil with creamy
exudate, and painful right submandibular lymphadenopathy. Throat culture on blood agar yields numerous small ßhemolytic
colonies that are inhibited by bacitracin.
166. For the past week, an 18-year-old patient has had fever, sore throat, and malaise, with bilaterally enlarged tonsils,
tonsillar exudate, diffuse cervical lymphadenopathy, and splenomegaly. There is lymphocytosis with atypical lymphocytes.
The patient tests positive for heterophile antibodies.
167. A 21-year-old patient has mild fever, a sore throat, and pharyngeal erythema without tonsillar exudate. A throat culture
on Thayer-Martin agar yields colonies of gram-negative diplococci that are oxidase-positive and ferment glucose but not
maltose or sucrose.
