Case of the Week 579

Here is our monthly case from Idzi Potters and the Institute of Tropical Medicine, Antwerp. The following were seen in a direct wet preparation of an unfixed stool specimen from a patient with bloody diarrhea and recent travel to sub-Saharan Africa. The objects in question measure approximately 20 micrometers long. Identification?

    This amoeba trophozoite is phagocytosing red cells, the identity should be E. histolytica. Beautiful case Idzi. Working only with fixed fecal samples deprives us of such dramatic findings.

    Agree with E. histolytica, magna form, with two red passengers.

    And indeed Florida Fan, also in our lab, more and more samples are being sent by mail (and therefore fixed), so these nice images become more and more exceptional...
