This weeks case features the following small, oval-shaped, red-staining objects seen in a bronchoalveolar specimen from an immunocompromised patient. The objects measure approximately 2 micrometers long. The stain is a strong trichrome (chromatrope 2R method). Identification? What is the significance of this finding? (CLICK ON IMAGES TO ENLARGE)
Not a parasite LOL Get those buggers off this page and send them to the Mycology lab. :)
ReplyDeleteHa! A wise guy ;)
ReplyDeleteFollowing Dr. Couturier’s lead, we may have a “ball”.
ReplyDeleteYet I need more clues before banging my head against the wall.
They often say “no pain no gain”,
For me one more week of itch and pain.

First instinct is one of the Microsporidia sp especially given the stain and the patient being immunocompromised.
ReplyDeleteMicrosporidia.
ReplyDeleteIs that round structure a Cryptosporidium?
I would like to know the protocol for the stain used if possible.

ReplyDeleteAh, now I see, size wise more likely Microsporidia.
