The following were seen on stool agar culture from a patient treated with steroids for another condition. The patient presented with recurrent enterococcal meningitis and was being treated with antibacterial agents. (CLICK ON THE BOTTOM RIGHT OF THE MOVIE VIEWER TO ENLARGE)
A wet prep of the preserved stool specimen showed similar rhabdiform worms with a short buccal cavity.
Note: for those of you who aren't familiar with the stool agar culture, here is the general gist of the assay:
Stool is placed on a clear nutrient agar (standard sheep blood agar for bacterial culture also works but is harder to see through). The Petri dish is then taped shut and the plate is examined over a period of 4 or more days for any evidence of bacterial growth patterns consistent with migrating worms in the stool.
