Abstract

A portion of a female hookworm identified as a species of Ancylostoma was recovered from the vitreous of a patient in Sri Lanka. The worm was dead with a cellular tissue reaction around the anterior part of the body. The internal structure of the worm, which was severed at the anterior end, was not clearly discernible but the characteristic mucron at the tip of the tail confirmed that it is an Ancylostoma sp. In the absence of the mouth end it is not possible to clearly identify it to the species, but it is believed to be A tubaeforme based on its width, short tail, thicker cuticle, and the space between transverse striations.

 

The probable mode of infection of the patient is discussed.

 

The patient had scanty hookworm ova in his stools but only a single female Necator americanus was recovered after treatment with anthelmintics.

 

An incidental observation of some significance was the finding of zoonotic Ancylostoma ova in the patient's son's stools, which needs further investigation.
