Lab final- Hematopoetic Flashcards
(34 cards)
Calf
normal- since it’s a calf
Haemopotetically active bone marrow
The bone marrow has a uniform consistency and its red to dark red. These responses are characteristic of hemapoteically ACTIVE BONE MARROW
- icetrus- yellowish discoloration
- Spleenmegaly
The mareked yellow discoloration, most strikely visible in the SQ fat is from high concentration of serum bilirubin produced as a result of the hemolytic anemia

Cause- canine parvovirus 2
associated lesion- lymphoid depletion; bone marrow depletion
cat- panleukopenia virus
