Clin path 2 RBC test latest /65 questions and
answers-All correct.
Rouleaux - -Cells stacked like coins
Increased protein levels
Increased inflammation
Normal in cat and horse
-Agglutination - -Cells clumped like grapes
Immunoglobulins attached to the surface
Autoimmune reactions
Transfusion reactions
-Hypochromic - -Decrease in red staining cytoplasm
Decreased intracellular [Hgb]
Iron deficiency
Increase in central pallor
Thinning of the cell
Can be normal in cats, horses, and pigs.
-Anisocytosis - -Cells of varying sizes.
Common in cows.
Normal in goats.
-Babesia spp. - -Intracellular oval to tear-drop or pear shaped trophozoite (protozoan).
Pale blue with reddish eccentric nucleus. Inside RBC.
Causes hemolytic anemia.
Transmitted by Boophilus spp. ticks in large animals.
Reportable in cattle.
-Anaplasma spp. - -A. marginale: Found on the margin of the erythrocyte.
A. centrale: Found within the erytrocyte.
Round to oval dark staining basophilic parasites.
Hemolytic anemia.
-Cytauxzoon felis - -Resembles signet ring.
Transmitted by ticks.
Causes anemia in cats- usually fatal.
-Eperythrozoon spp. - -Small basophilic rings upon or between erythrocytes.
Cause hemolytic anemia.
Host specific, Pigs-severe.
-Bartonella spp. - -Small rod shaped, gram negative bacteria found inside RBC.
Bartonella henselae; Cause of "Cat scratch fever", Zoonotic.
Normally not seen in the blood, but can be cultured.
-Trypanosoma in cattle, sheep, goats. - -Sleeping sickness.
, Fever, anemia and weight loss.
T. congolense , T. vivax , and T. brucei.
From Tsetse flies and Tabanid flies.
Dark staining sqiggles outside of RBC's in cytoplasm.
-Trypanosoma in humans, dogs, cats - -T. brucei brucei.
Tsetse flies and other biting flies.
Dark staining sqiggles outside of RBC's in cytoplasm.
-Trypanosoma cruzi - -Dark staining sqiggles outside of RBC's in cytoplasm.
Affects dogs, cats and humans; Chagas Disease.
Causes myocarditis
-Dirofilaria immitis - -Heartworms. Nematode parasite.
Normally found in right side of the heart.
Tapered end. Coils and uncoils on slide.
-Dipetalonema reconditum - -Transmitted by fleas. Parasite of SQ tissues.
Hooked end. Glides across slide.
-Defintion/occurance of anemia? - -Decreased hemoglobin
Decreased hematocrit
Decreased RBC concentration
-Is the reduced capacity to carry oxygen to tissues.
-Signs of anemia - -Decreased exercise tolerance
Weakeness
Depression
Increased respiration
Physical findings
Pale mucous membranes
Systolic heart murmur
-How to classify anemia - -Marrow response
Morphologic
Pathophysiologic
-Morphologic classification of anemia - -Normocytic: normal maturation.
Microcytic: Increased mitosis during maturation.
Macrocytic: Young RBC's.
Normochromic: Hbg synthesis complete.
Hypochromic: incomplete Hbg synthesis.
-RBC abnormalities that support reticulocytosis - -Anisocytosis
Howell-Jolly bodies
Codocytes
Basophilic stippling
-Marrow response anemia - -Regenerative or nonregenerative
