Q

Rouleaux formation

is normal in which species?

A

Horses

17
Q

Rouleaux formation is caused by an

increase in _______

due to antigenic stimulation

secondary to inflammation

A

globulin

18
Q

In a dog,

Rouleaux formation can be confused with

Agglutination. What is indicated by each?

A

Rouleaux formation = Ehrlichia

Agglutination = IMHA

19
Q

Giant platelets and RBCs with central pallor

are indicative of this disease

A

Iron-Deficiency Anemia

20
Q

What is aniscytosis?

What can it tell you?

A

A variation in RBC size

If RBCs are larger, Macrocytic= Regenerative anemia

If RBCs are smaller, Microcytic= Iron-Def anemia

21
Q

Basophilia, vacuolation of the cytoplasm, and

presence of Dohle bodies are indicative of

A

Neutrophil Toxic Change

which means INFLAMMATION

22
Q

What type of morphological change is seen

in neutrophils that are in circulation too long?

A

Hypersegmented Neutrophils

23
Q

Hypersegmented neutrophils are

caused by what 2 processes?

A

Cushing’s Disease (increased endogenous steroids)

Steroids (Prednisone) (exogenous steroids)

24
Q

A plasma cell that has spherical inclusions of

clumped immunoglobulins that

indicate either

Chronic Inflammation or B-Cell Lymphoma

A

Mott Cells

with Russel Bodies

25
Q

What is a ghost cell and what does it

indicate?

A

An empty RBC, indicates IMHA

26
Q

If you see metamyelocytes, you can be sure

that severe ______ is present

Metamyelocytes are very immature neutrophils

A

SEVERE inflammation

27
Q

If you see large-SIZED lymphocytes,

what is your probable diagnosis?

A

Lymphoid leukemia

28
Q

If you see large monocytes, what can be causing it?

A

Stress or Inflammation

29
Q

The presence of eosinophils

indicates these 3 conditions

A

Immune-complex reaction

Allergic inflammation

Parasites

30
Q

What type of change would be seen in

neutrophils if the host has abscesses or septicemia?

A

Neutrophil degeneration

31
Q

A red blood cell with hypochromasia

is indicative of

A

Iron-deficiency anemia

32
Q

RBC agglutination is indicative of IMHA,

where this antibody attaches to the RBCs

A

IgM

33
Q

What are Dohle bodies? What are their implications?

A

Dohle bodies are neutrophil intracellular inclusions

made of aggregated ribosomes (RER)

They indicated Toxic Change which means

INFLAMMATION is present
