* Lymphocytosis is an increase in numbers of lymphocytes in the blood.
* Occurs:
** In tumours in which there is a substantial increase in their number.
*** Some of the lymphocytes are immature - lymphoblasts.
*** For example, Bovine Leukosis.
** Following adrenaline release in fear, excitement and so on.
** In some cases of chronic infection.
*** However, reactive hyperplasia in associated lymph nodes may not correlate with the numbers of circulating lymphocytes.
** Commonly in growing swine.
*** Possibly associated with aMycoplasma infection.
