Ascariasis in people and pigs: New inferences from DNA analysis of worm populations

► Comparison of human and pig Ascaris by molecular phenotypic and genetic markers. ► Inference of transmission of Ascaris between and among humans and pigs. ► Inference of host affiliation and infection success. ► Inference of evolutionary history from genetic data. ► Use of genetic markers to study mating dynamics, diagnostics and paleoparasitology.
