Lymphopenia in Animals Lymphopenia is a common leukogram abnormality most commonly associated with stress (endogenous) or corticosteroid administration (exogenous). The most likely cause is steroid-induced apoptosis of lymphocytes.

Lymphoma is a related cancer of certain white blood cells that begins in a lymph node or other lymphoid tissue ( see Malignant Lymphoma in Dogs). Leukemia should be considered a potential cause when there is an increase in the number of white blood cells in the bloodstream.
3 paź 2022 · A dog with lymphocytopenia has severely reduced lymphocytes in their blood. Dogs with weak immune systems may not be able to fight off viruses, bacteria, or fungi. Read on to learn more.
10 wrz 2016 · Lymphopenia is the most common alteration in the leukogram of dogs and cats and reflects chronic stress or long-term corticosteroid treatment. The acute glucocorticoid effect is classically a mature neutrophilia, lymphopenia, eosinopenia, and in dogs a monocytosis peaking at 4 to 12 hours post-treatment.
Lymphocytes are white blood cells that recognize "non-self" antigens, such as infectious organisms, foreign tissue, and cancer cells. Lymphocyte production in mammals begins in the bone marrow. Lymphocytes then become T cells, B cells, or natural killer cells.
The typical acute inflammatory leukogram is characterized by neutrophilia with a left shift, lymphopenia and variable monocytosis. The neutrophilia reflects the relatively large bone marrow storage pool in the dog and cat, and the movement of more neutrophils from marrow into blood than from blood into tissue.
24 lip 2016 · Lymphocytes consist of T cells, B cells, and natural killer cells. These cells are an integral part of the humoral and cell-mediated immune response. Morphologically, these cells are small and round with a scant rim of basophilic cytoplasm with a round nucleus and a condensed chromatin pattern.
