Textbook Question
Chapter 20, Problem 3AYKA
Mr. White has been diagnosed with febrile neutropenia, a condition characterized by the presence of a fever with an extremely low number of neutrophils in the blood. Blood work demonstrates the presence of bacteria in his blood. Explain why neutropenia might lead to a bacterial infection. Why is a bacterial infection particularly dangerous for Mr. White?

Neutrophils are best described as:
(a) Phagocytic, have bilobed nucleus and are small (2-5 microns)
(b) Respond to chemokines and are primary defense against bacteria
(c) Long-lived phagocytic cells.
