Case 151:
A 39-year-old female had a descending colon biopsy to determine the
cause of symptoms that included chronic abdominal pain and discomfort. No pertinent travel
history was known. Worm-like objects were detected during the
biopsy, and some were recovered. The specimens were sent to the
South Carolina state health department laboratory for identification. Lab personnel
at the state took digital images (Figures A-C) and sent them to DPDx
at CDC for assistance in making an identification via telediagnosis. What is your
diagnosis? Based on what criteria?

Case 152:
A 25-year-old male went to a local hospital complaining of a two-week
history of worsening irritation of his left eye. He resides in a
semi-rural area, where sheep and horses are raised, and recently returned
from Samoa four weeks previous to his hospital visit. While at the
hospital, he mentioned that he saw an object crawling on his
conjunctiva and removed it. He could not remember any specific
event that initiated these symptoms. Upon examination by slit lamp, three larvae were seen and it
was noted that they moved away from the light. The larvae (Figures
A-C),
measuring approximately .75mm in length, were removed and sent to the
laboratory for identification. What is your
diagnosis? Based on what criteria?
