Case 241
A small, cream-colored worm-like object was discovered in the diaper of
a 15-month-old child. The suspect worm was collected by the
child’s parents and sent to the State Health Department for
identification. A laboratorian at the State Laboratory identified
the worm but requested confirmation. The specimen was sent to the
Reference Laboratory at CDC for diagnostic assistance. Figures
A and B show the gross morphology of the specimen.
Figures C and D show smaller structures that were observed
in the transport medium (10% formalin). These smaller structures
were approximately 85 micrometers in length. What is your
diagnosis? Based on what criteria?

Case 242
A nine-year-old boy from Central America, who had recently immigrated to
the United States with his family, was taken to a local health facility
with complaints of intestinal cramping and intermittent diarrhea.
A stool specimen was obtained for ova and parasite (O&P) testing. A
formalin-ethyl acetate (FEA) concentration was performed. The
following figures show what was observed on a wet mount prepared from
the concentrate. Figure A was taken at 100x magnification;
Figures B-D at 400x magnification (Figures B and
C are of the same field but in different planes of focus). The
large objects of interest measured approximately 52 micrometers in
length by 22 micrometers in width. What is your diagnosis?
Based on what criteria?
