What do Dohle bodies indicate?

The presence of Döhle bodies, nuclear immaturity, “toxic” cytoplasmic granulation, and giant platelets may indicate, at least in some measure, a general metabolic disturbance of the hematopoietic system.

What are Dohle bodies in dogs?

Döhle bodies: These are pale round to linear blue aggregates in the cytoplasm, caused by whorls of rough endoplasmic reticulum (see image to the right). This is often the earliest and first indication of toxic change.

What are Dohle bodies composed of?

Döhle bodies are small, round or oval, pale blue–grey structures usually found at the periphery of the neutrophil. They consist of ribosomes and endoplasmic reticulum.

What causes toxic neutrophils in dogs?

Disorders Related to Increased or Decreased White Blood Cells. Neutrophilia is an increase in the number of neutrophils in the bloodstream and is caused by inflammation. Structural changes in neutrophils may occur during severe inflammation and are referred to as toxic changes.

Can chemo cause toxic granulation?

Toxic granulation is often found in patients with bacterial infection and sepsis, although the finding is nonspecific. Patients being treated with chemotherapy or granulocyte colony stimulating factor, a cytokine drug, may also exhibit toxic granulation.

What are monocytes in dogs?

Mono is an abbreviation for monocytes. This white blood cell helps the neutrophils fight infections. High monocyte counts indicate infection. It is unlikely that there will be no monocytes and a differential with zero monocytes does not indicate any specific ailment.

What does toxic granulation look like?

Toxic granulation is manifested by the presence of large granules in the cytoplasm of segmented and band neutrophils in the peripheral blood. The color of these granules can range from dark purplish blue to an almost red appearance.

Can monocytes have toxic granulation?

AR bodies in neutrophils may resemble heavy toxic granulation, however, Reilly bodies can also be present in monocytes and lymphocytes, whereas toxic granulation occurs only in neutrophils.

What causes elevated monocytes in dogs?

Monocytes may be increased in pets with chronic infections. Eosinophils and basophils are increased in pets with allergic diseases, or parasitic infections (worms, fleas, etc.). Platelets are produced in the bone marrow and are involved in the process of making a blood clot.
