Case of the Week 397

This week's case is a blood specimen from an elderly gentleman from Arkansas. He is asplenic and has received multiple blood transfusions for chronic anemia. Below are images from Wright-Giemsa stained thin films taken by our Clinical Microbiology fellow, Poornima.



Identification?
What is the likely species involved in this case?

    Babesia...Do you see much of that in the area, In Arkansas? Could also be transfusion related though...

    I have a question: Why does Babesia form the tetrad? is it the asexual reproduction of one ring to 4? It doesn't look like a multiple infection or other stage of development.

    Nice case of Babesia, most likely microstrip.

    Sorry for the mispelling, I meant Babesia microtti. The not always wonderful "Spelling Check" program simply threw me a curved ball.

    Babesia sp.- PCR for species identification would be helpful.Babesia duncani,microti,divergens, and the MO-1 strain should be considered.Missouri borders Arkansas.

    TTB - transfusion transmitted B. microti
