Case Presentation
Jason Hornbuckle is not a happy little boy. For the past 24 hours he has complained of pain when he swallows, has a headache, and has vomited twice.

A throat swab taken before starting antibiotics grows beta-hemolytic streptococci (Group A). After three days of treatment, Jason’s temperature has returned to normal and he has made an uneventful recovery.

3. Describe the results of the CBC. Describe the role neutrophils play in the resolution of a bacterial infection. In the course of...
