Sample records for oxyuroidea

  1. WHY MUSEUMS MATTER: A TALE OF PINWORMS (OXYUROIDEA: HETEROXYNEMATIDAE) AMONG PIKAS (OCHOTONA PRINCEPS AND O. COLLARIS) IN THE AMERICAN WEST.

    Permanent and well supported museum collections provide a solid foundation for the process of systematics research through creation of an empirical record which validates our understanding of the biosphere. We explore the role of museums in ongoing studies of the complex helminth fauna characterist...

    Spauligodon papuensis sp. nov. from the large intestines of Cyrtodactylus epiroticus (Gekkonidae) from Papua New Guinea is described and illustrated. Spauligodon papuensis sp. nov. represents the 54th species assigned to the genus and the second species from the Oceanic Region. The new species is separated from congeners by the unique combination of aspinose filamentous tail and no spicule in the male; and spinose filamentous tail, fusiform, flanged eggs, and postbulbar vulva in the female. Four additional species of nematodes were also found in C. epiroticus: mature specimens of Cosmocerca zugi, Falcaustra papuensis, Physalopteroides milnensis and larvae of Abbreviata sp.

    Pharyngodonid nematodes (Oxyuroidea) belonging to the genus Alaeuris Thapar, 1925, were collected from the posterior gut of Gallotia stehlini (Lacertidae) from Grand Canary Island. Two species Alaeuris stehlini n. sp. and Alaeuris numidica canariensis n. ssp. were identified. The new species is described in which the long thin males are characterized by narrow caudal alae, a rounded first pair of adanal papillae non pedunculate, the second pair attached and elongate, the three pair teated; a short narrow V plate and a relatively long caudal appendage. The females are also long and thin with a slightly salient vulva, a conical pointed caudal appendage, oesophageal length approximately one third of body, excretory pore below the oesophageal bulb. The new subspecies most closely resembles Alaeuris numidica numidica. (Seurat, 1918) Petter, 1966 and Alaeuris numidica madagascariensis Petter, 1966.

    Full Text Available Abstract Background Analyses of coprolites have contributed to the knowledge of diet as well as infectious diseases in ancient populations. Results of paleoparasitological studies showed that prehistoric groups were exposed to spurious and zoonotic parasites, especially food-related. Here we report the findings of a paleoparasitological study carried out in remote regions of Brazil’s Northeast. Findings Eggs of Pharyngodonidae (Nematoda, Oxyuroidea, a family of parasites of lizards and amphibians, were found in four human coprolites collected from three archaeological sites. In one of these, lizard scales were also found. Conclusions Through the finding of eggs of Pharyngodonidae in human coprolites and reptile scales in one of these, we have provided evidence that humans have consumed reptiles at least 10,000 years ago. This food habit persists to modern times in remote regions of Brazil’s Northeast. Although Pharyngodonidae species are not known to infect humans, the consumption of raw or undercooked meat from lizards and other reptiles may have led to transmission of a wide range of zoonotic agents to humans in the past.
