This week's case was generously donated by Dr. Piryanka Uprety and the excellent Clinical Microbiology and Hematology Laboratories at the University of Pennsylvania. The following structures were initially observed by a hematology fellow in a wet mount (40X) from a BAL specimen. Photographs and videos are courtesy of Joyce Richardson, Vivian Whitener, and Darrin Jengehino from the Hematology Laboratory.
Wet preparation of the BAL fluid with iodine showed the following:
A return to the brush cells of the respiratory tract, the hairs move in conjunction to expel the particles trapped by secretions of the goblet cells. Certainly the movement of the brush hairs have created some excitement to many. These "pseudo-parasites" would not fool most experienced parasitologists. Florida Fan
Indeed! Ciliated respiratory epithelial cells! In pictures 1 and 3, the typical (more intensely staining) border is clearly visible (on the side of the cilia).
Every week I will post a new Case, along with the answer to the previous case. Please feel free to write in with your answers, comments, and questions. Also check out my image archive website at http://parasitewonders.com. Enjoy!

Not a parasite. Ciliated respiratory epithelial cells.
Agreed. Ciliated respiratory epithelial cells. Exciting to witness, but certainly not a parasite.
Movement seen in video may make us think about some parasite but iodine stained pics show clear resp celiated cells...

how do I submit a case?
Hi Anon! I gladly take cases from other professionals in the field. I do not accept cases from patients, however, and do not provide medical opinions
