Case of the Week 716

 Happy May, everyone! As the first Monday of the month, it's time for our post from Idzi Potters and the Institute of Tropical Medicine, Antwerp. Idzi was recently featured in a great article by the Institute - you should check it out! 

This month's case are the following objects seen in 3 different stains from a patient with sudden onset of profuse watery diarrhea and abdominal cramping:

Concentrated wet preparation with Lugol's iodine

Heine stain


Modified acid fast stain

What is your diagnosis?

So timely for the summer. People get out and eat. Little do they know Cyclospora cayetanensis is just awaiting. This serves as a wake up call for all of us.

Oocyst for Cyclospora.

I think that because of the size it could be Ciclospora cayetanensis. Long time since I have put foot in a laboratory, so I hope my memory serves me right.
