Case 204:
A mother found objects that she thought were maggots in the diaper of her 10-month-old child.  She submitted the specimens to her state health department for identification and advice.  Figures A and B show the submitted specimens using a low power dissecting microscope.  The smaller white objects were released when one of the specimens was dissected, and two of the objects are shown in Figures C and D at 400× magnification using a compound microscope.  These objects measured 200-250 micrometers and contained individual structures measuring approximately 40 micrometers.  Digital images were captured and sent to DPDx for confirmation.  What is your diagnosis?  Based on what criteria?

A	B

C	D
