Description
Lymphocytosis refers to an increase in the number of circulating lymphocytes in the blood. The major causes of lymphocytosis are:
- Neoplasia
- Several types of tumour may result in increases in the number of blood lymphocytes, including:
- Stage V lymphoma
- Acute lymphoblastic and chronic lymphocytic leukaemia
- Bovine Leukosis caused by bovine leukaemia virus
- Several types of tumour may result in increases in the number of blood lymphocytes, including:
- Stress
- Following adrenaline release in fear, excitement and so on.
- Chronic infection
- In some cases of chronic infection.
- However, reactive hyperplasia in associated lymph nodes may not correlate with the numbers of circulating lymphocytes.
- In some cases of chronic infection.
- Physiological
- Commonly in growing swine.
- Possibly associated with aMycoplasma infection.
- Commonly in growing swine.
- Equine neonates
