Oxyuridae infect a wide range of mammalian hosts and have a unique reproductive strategy that involves conventional horizontal transmission, as well as re-infection of an already infected host. We asked the question, do the unique aspects of pinworm life-history explain an exception to the widely observed patterns of aggregation of parasite populations?<jats:bold>Methods.<\/jats:bold>We empirically examined the differences among Oxyuridae (genus:<jats:italic>Syphacia<\/jats:italic>) compared with other helminth (genus:<jats:italic>Heligmosomoides<\/jats:italic>) parasite aggregations in 2 rodent hosts with similar ecology: the yellow-necked mouse (<jats:italic>Apodemus flavicollis<\/jats:italic>) from Trento, Italy and the white-footed mouse (<jats:italic>Peromyscus leucopus<\/jats:italic>) from Pennsylvania, USA. To investigate the effects of pinworm life-history characteristics on generating aggregation, we present a stochastic model that explores aggregation under a range of host-self-infection, parasite death, and transmission scenarios.<jats:bold>Results.<\/jats:bold>Oxyuridae parasites had consistently greater aggregation compared to other nematodes regardless of host or parasite species identity, and pinworm aggregation exceeded the range of macroparasite aggregation described previously.<jats:bold>Conclusions.<\/jats:bold>Our simulations demonstrate that host-self-infection, on its own, is sufficient to generate aggregation values greater than the predicted values.<\/jats:p>","DOI":"10.1017\/s0031182011000096","type":"journal-article","created":{"date-parts":[[2011,2,24]],"date-time":"2011-02-24T15:33:25Z","timestamp":1298561605000},"page":"619-627","source":"Crossref","is-referenced-by-count":16,"title":["The
