Parasite Case of the Week 542
This week's case is a lovely gif image compiled by our excellent parasitology technical specialist, Heather Arguello. The following structures were seen on a non-nutrient agar culture that had been inoculated with corneal scrapings. The plate had been overlain with Escherichia coli to provide a food source for parasites that may be present in the specimen. The central structure is ~40 micrometers in maximum dimension, while the rounded structure to the left is ~15 micrometers in diameter. Identification?

Acanthamoeba species. Very cool video.
Would this be a stat report?

Ah! El patiente he usado agua sucia por lavar sus lentes de contacto. Caso típico de infección con Acanthamoeba.

Agree with my predecessors. Cyst(wrinkled double wall) and trophozoite of Acanthamoeba spp.

Estoy de acuerdo con mis predecesores. Buena idea la del gif animado por cierto.

Thanks for the responses! Why the Spanish? I feel like I'm missing something :)
To answer BW - yes, we consider this a critical result that gets called to the provider immediately.
Thanks for the wonderful imagery. i can now take " a microscopic view of Acathameoba" off my bucket list.
Nicely captured video of cyst and trophozoite of Acanthamoeba...
Very nice video of the trophozoite and cyst of Acanthamoeba. The video at times does suggest the "thorny" morphology. The shrinking away from the cell wall of the cyst is also diagnostic of the infection.
Definitely a stat call to the physician is necessary.
Wonder if the patient makes his own lens cleaner?
