Case of the Week 467
This week's post is the second in my new collaboration with the Institute of Tropical Medicine Antwerp and Idzi Potters. The following objects were seen in a urine specimen from a 73 year old man. They measure approximately 150 micrometers in length. The specimen was delayed in getting to the laboratory, and the patient indicated that it was mixed with toilet water.

They're adorable. My guess is a non-pathogenic Paramecium, possibly caudatum.
miracidium of Schistosoma haematobium
Interesting case! They look like Schistosoma miracidia. Probably of S. haematobium, as it is a urine sample; I even thought I saw red blood cells, which would indicate hematuria that is compatible with genitourinary schistosomiasis.
That's really cool! I browsed youtube for miracidia videos (miracidios?) and the motility of this one looks most like S. haematobium.

My bet will be miracidium of S. haematobium with its pointed front end, Paramecias do not have this morphological aspect. The presence of red cells also is indicative of the infection.

Idzi,
Merci beaucoup pour un cas très intéressant. Votre œuvre photographique est incroyablement superbe. Notre connaissance des parasites sera meilleure grâce à votre contribution.

This is Schistosoma spp miracidium!
Merci pour ces compliments, Florida!
C'est toujours agréable d'entendre que mon travail est bien apprécié!
Et ça me rend heureux quand les gens trouvent mon travail intéressant!
Encore une fois merci!!!

From my basic biology this looks like a euglena or shistosoma. Paramecium have cilia throughout the body with a curvature and nucleus. The monentum is not that of an amoeba.
Aw, this was an incredibly good post. Taking a few minutes and actual effort to generate a very good article… but what can I say… I put things off a lot and don't manage to
get anything done.
But is there any terminal spine?
I have a similar video like this. How can I post it here???
