A 25-year-old refugee from Myanmar had a stool specimen collected for routine ova-and-parasite examination as part of a post-arrival screening. Figures AD show what was found in moderate numbers on a fecal smear stained with Kinyoun’s modified acid-fast stain.  The objects measured 20 micrometers on average.  What is your diagnosis?  Based on what criteria?
