Fun Fact Q6: Do NHP have a lot of Heinz bodies?

I had a call from a colleague this week saying...
 “ I’ve got this blood sample from a NHP (turns out it was a Goeldi’s monkey) and I don’t know what to make of it.  It seems to have a lot of Heinz bodies – is this normal?"

So this weeks questions are about blood samples with interesting features.

·      Give an example of an inherited disorder that results in this pathology

·      Apart from inherited disorders, what other conditions can result in this pathology in animals?

·      What stain is often used to highlight Heinz bodies?

·      Marmosets also often have Howell Jolly bodies in their blood. What is a Howell Jolly body?

·      The presence of a large proportion of Howell Jolly bodies usually indicates what pathology?
