Case Presentation

Question Answered step-by-step Case PresentationJason Hornbuckle is not a happy little boy. For the past 12 hours, he has complained of pain when he swallows, has a headache, and has vomited twice. His mother decides to take the seven-year-old to his pediatrician. Upon examining Jason, the doctor finds that Jason’s pharynx, tonsils, and uvula are swollen and erythematous (red) and his tonsils are studded with white areas of exudate. He is febrile (temperature 40.3 degrees centigrade) with tender, bilateral, cervical lymphadenopathy (enlarged lymph nodes).A Complete Blood Count (CBC) performed on a sample of Jason’s blood reveals that he has a leukocytosis (increased number of WBC) due to a neutrophilia (increased number of neutrophils).Jason is diagnosed as having acute bacterial pharyngitis and treatedwith phenoxymethyl penicillin for five days. A throat swab taken beforestarting 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.   Questions1.

What role do neutrophils play in the resolution of a bacterial infection? In the course of your answer explain terms such as adhesion molecules, diapedesis, chemotaxsis, opsonization, and phagocytosis.
