The following objects were seen in a fresh stool specimen collected at a field station in Uganda. The objects are approximately 280 µm long and no longer motile upon examination. What is your identification?
My general feeling is that this is a free-living rhabditoid imposter, but I wish the esophagus was better shown before committing to that absolutely. The stringy tail and “non-motile” observation (spurious passage?) point me that way too…
These larvae do not resemble those of human infections. Following previous comments, I wonder whether Dr. Pritt introduce to us some exotic larvae, possibly of murine origin?
Hookworm rhabditiform larva. The larva doesn't seem to have the bulbous oesophagus you would expect from Strongyloides. It's likely hatched from eggs in a faeces specimen that has been left at room temperature (i.e. delay in processing).
It is a larva of Strongyloides stercoralis
