Fluorescence micrograph of S. stercoralis L3i which have ingested FITC-containing culture medium. The pharyngi of the two worms, which are coiled about each other, fluoresce strongly, while their intestines also contain fluorescent material (non-feeding, control larvae show almost no structure under these conditions).
