  1. Looks like a dust mite, not clinically significant.

    Free-living mite, looks like Glycophagus or related. That it is still alive probably means it contaminated the specimen during slide preparation (e.g. wasn't in the stool during passage nor processing)

  3. Just a mite that contaminate the sample , without any clinical significance

  4. For sure it is a mite, not an itch mite. I don’t think it comes from a succulent morsel of Mimolette as it is still very alive in the video. As such, Blaine’s comments are very much plausible.

  5. Ditto Blaine's response with one difference I'd like to think it was a cheese mite which escaped from someones wonderful Italian cheese lunch.

  6. As already said, it is one of the storage mites, I go for Tyrophagus, which has no clinical significance. If it is not an external contamination during collection and examination of the fecal material, it should be assumed that it was ingested with the food and now appears in the feces. In this case I am surprised that it is still alive.

  7. I mite have to say this is a contamination of the preparation and not coming from stool.

  8. This might be a mighty mite :). Contamination for certain. I'm not sure about the species.

  9. I think it a cheese mite. The action of the living mites on the surface of cheeses contributes to the flavor. Mite cheese is produced using Tyrophagus casei, Mimolette cheese uses Acarus siro (flour mites). Mimolette cheese have live cheese mites in its rind which is thought to contribute to the cheese's distinct rind texture.
