Figure 1 Strongyloides stercoralis infection occurs when filariform larvae from the soil penetrate the skin, pass through the circulation to the lungs, enter the airways, and are then swallowed. In the small-intestinal mucosa, the larvae mature into adults (Panel A, long arrow) and deposit eggs that release first-stage rhabdoid larvae (Panel A, short arrow; hematoxylin and eosin, ×105). These larvae are the usual diagnostic feature in the stool specimen (Panel B; iodine stain, ×505) and are identified by their short buccal cavity (long arrow) and prominent genital primordium (short arrow).
