Greek: strongylos = rounded; oides = similar. Latin: papillosus = with papillae; sus = pig; rattus = rat; aves = birds; stercoralis = within feces; procyon = racoon; robustus = strong.  Fuelleborn: German parasitologist.

Geographic Distribution/Epidemiology

Worldwide, mostly in countries with warmer climates.

Morphology/Life Cycle

The life cycle of the different species runs as is diagrammatically depicted in Fig. 1. All species which are mostly very tiny with diameters of 0.1 mm or less live in the intestines of their hosts (parthenogenic females)) and outside of the body (free living male and female stages). The free living females reach a length of 0.9 mm, the males 0.7 mm, and thus are considerably shorter than the parthenogenic females in the intestines of their hosts (see Table 1). Eggs are depicted in Fig. 2, parthenogenic females in Fig. 3.
