@StephenTristram @ARUPLabs I took the images from the routine O&P that was sent to us. I do not have any clinical information except that the patient was from "Appalachia" and was REALLY sick. No PMH or underlying diagnosis provided. Just very sick was all we were provided with.

This was a fun. The worm was barely recognizable as a worm. It vaguely looked like a proglottid, but the specimen was badly degraded. Clearing the tissue with some lactophenol exposed the genus-level ID. Taenia eggs in utero. Hooklets visible even! #Parasitology @ParasiteGal

Super excited for this new work our team published (Dr. Angela Ma now at Public Health Ontario & Blaine Mathison at ARUP!). UV autofluorescence microscopy is a great tool that I share pictures of here often πŸ’‘πŸ”¬πŸͺ© #parasitology @ParasiteGal @ARUPLabs

@SBtotheDub Completely inaccurate and difficult to control, manual, human, subjective method. But yeah, A.I. is a problem... πŸ€¦πŸ»β€β™‚οΈ

Friday, Funday. This is what we consider...a whole lot of Dientamoeba fragilis! Mostly binucleate forms with variably fragmented karyosomes. #parasitology @ARUPLabs @ParasiteGal

@ARUPLabs @ParasiteGal These are larvae of Ixodes sp. One might assume I. scapularis based on geography, but the necessary features to key out larvae to species are difficult to discern.

@girlneedsanap @ARUPLabs @ParasiteGal Ixodes larvae is correct! Well done. Likely I. scapularis, but hard to key out to species with just larvae.

@SBtotheDub @LAGenHospMed @USCPathology Cool! Is this your own assay or a sendout? What is the specificity like for Histo/Blasto?

@leon_metlay @ParasiteGal @ARUPLabs It was a 10% formalin tube...but it was likely inoculated with too much stool, thus diluting the fixative too much. This was a reference lab submission...so I have no information on the nature of the collection unfortunately.

@StephenTristram @ARUPLabs @ParasiteGal No problem at all. Please just credit the image to me (inconspicuous is totally fine) since I do not watermark my images.
