leukocytosis

All inflammatory and suppurative diseases cause leukocytosis, except when slight or well walled off.

The infectious diseases in which leukocytosis is absent (p. 160) often cause a slight decrease of leukocytes.

Chemotaxis alone will not explain the continuance of leukocytosis for more than a short time.

A well-marked leukocytosis usually indicates good resistance.

Non-phagocytic leukocytosis is probably due more to stimulation of blood-making organs than to chemotaxis.
