Tapping Into Natural History Collections To Assess Latitudinal Gradients Of Parasite Diversity, Sebastian Botero-Cañola, Scott Lyell Gardner

Scott L. Gardner Publications

Parasites are key components of the biosphere not only due to their huge diversity, but also because they exert important influences on ecological processes. Nevertheless, we lack an understanding of the biogeographical patterns of parasite diversity. Here, we tap into the potential of biodiversity collections for understanding parasite biogeography. We assess species richness of supracommunities of helminth parasites infecting mammal assemblages in the Nearctic, and describe its relation to latitude, climate, host diversity, and land area. We compiled data from parasitology collections and assessed parasite diversity in Nearctic ecoregions for the entire parasite supracommunity of mammals in each ecoregion, as …

Molecular Identification Of Parasites In An Intestinal Coprolite From A Mummified Religious Dignitary Of The Piraino Mother Church Crypt, Sicily, Amanda Rollins, Krystiana Krupa, Georgia Millward, Dario Piombino-Mascali, Karl Reinhard, Frederika Kaestle

Karl Reinhard Publications

Intestinal contents were sampled from a spontaneously enhanced mummy from the Sepulcher of the Priests of the Piraino Mother Church in the Province of Messina, Sicily. This adult male mummy, Piraino 1, is an unidentified religious dignitary dating from the late-18th to mid-19th centuries. Immunological and molecular diagnostics were used to test for common and clinically significant parasites. A morphological diagnosis of Trichuris trichiura (whipworm) was confirmed genetically. A previously undetected Enterobius vermicularis (pinworm) infection was also identified genetically. These data indicate that the Piraino 1 individual was simultaneously infected with multiple intestinal parasite species indicative of poor hygiene. This …

Neonchocotyle Violantei N. Sp. (Monogenea, Hexabothriidae) From Pseudobatos Lentiginosus (Rhinopristiformes, Rhinobatidae) Of Yucatán, Gulf Of Mexico = Neonchocotyle Violantei N. Sp. (Monogenea, Hexabothriidae) Do Pseudobatos Lentiginosus (Rhinopristiformes, Rhinobatidae) De Yucatán, Golfo Do México, Guadalupe Quiterio-Rendon, Scott Monks, Griselda Pulido-Flores

Abstract

Neonchocotyle violantei n. sp. (Monogenea: Hexabothriidae) infects the gill of the Atlantic guitarfish, Pseudobatos lentiginosus (Rhinopristiformes, Rhinobatidae) from littoral waters of Celestún, Yucatán, Mexico. It is assigned to Neonchocotyle because it has, among other features, an asymmetrical haptor, a seminal receptacle, a smooth oötype, and an egg with two elongate filaments. It differs from Neonchocotyle pastinacae, the only congener, by having a small body (821 long by 315 wide, length to width = 2.6:1), two pairs of microhooks between the haptoral appendix suckers, extracaecal (submarginal) vaginal pores, and 5-9 testes. This is the first record of a species …

A New Species Of Acanthobothrium (Eucestoda: Onchobothriidae) In Aetobatus Cf. Narinari (Myliobatidae) From Campeche, México = Uma Nova Espécie De Acanthobothrium (Eucestoda: Onchobothriidae) Em Aetobatus Cf. Narinari (Myliobatidae) De Campeche, México, Erick Rodríguez-Ibarra, Griselda Pulido-Flores, Juan Violante-González, Scott Monks

Abstract

The helminthological examination of nine individuals of Aetobatus cf. narinari (spotted eagle ray; raya pinta; arraia pintada) revealed the presence of an undescribed species of cestode of the genus Acanthobothrium. The stingrays were collected from four locations in México: Laguna Términos, south of Isla del Carmen and the marine waters north of Isla del Carmen and Champotón, in the State of Campeche, and Isla Holbox, State of Quintana Roo. The new species, nominated Acanthobothrium marquesi, is a category 3 species (i.e, the strobila is long, has more than 50 proglottids, the numerous testicles greater than 80, and has …

Pritchardia Boliviensis N. Gen., N. Sp. (Anoplocephalidae: Linstowinae), A Tapeworm From Opossums (Didelphidae) In The Yungas And Lowlands Of Bolivia And Atlantic Forest Of Paraguay, Scott Lyell Gardner, F. Agustín Jiménez Ruiz, Mariel L. Campbell

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Pritchardia boliviensis n. gen. n. sp. (Anoplocephalidae: Linstowiinae) is described from marsupials (Marmosops noctivagus, Metachirus nudicaudatus, Gracilinanus sp.) collected in Bolivia and Paraguay. These cestodes have a very small strobila with only three segments, regularly alternating genital pores, genital ducts crossing excretory canals ventrally, ovoid to pyriform cirrus sac, three to five testes, external seminal vesicle present and separated from cirrus sac by long seminal duct surrounded by glandular material, uterus ephemeral, eggs forming rapidly in gravid segments, and seminal receptacle present. Pritchardia boliviensis n. sp. includes a single species that occurs in small marsupials in the family …

Return To Beringia: Parasites Reveal Cryptic Biogeographic History Of North American Pikas, Kurt E. Galbreath, Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Traditional concepts of the Bering Land Bridge as a zone of predominantly eastward expansion from Eurasia and a staging area for subsequent colonization of lower latitudes in North America led to early inferences regarding biogeographic histories of North American faunas, many of which remain untested. Here we apply a host–parasite comparative phylogeographical (HPCP) approach to evaluate one such history, by testing competing biogeographic hypotheses for five lineages of host-specific parasites shared by the collared pika (Ochotona collaris) and American pika (Ochotona princeps) of North America. We determine whether the southern host species (O. princeps) …

Helminths Of Small Mammals (Erinaceomorpha, Soricomorpha, Chiroptera, Rodentia, And Lagomorpha) Of Mongolia, David S. Tinnin, Sumiya Ganzorig, Scott Lyell Gardner

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Ninety-eight species of small mammal, excluding carnivores and ungulates, are currently recognized in the fauna of Mongolia. A list of species of helminths known to infect these species, both within Mongolia and across their range, is presented in an effort to aid in their study. A detailed bibliography of pertinent survey and related publications is provided.

The publication is the result of the Mongolian Vertebrate Parasite Project, made possible by NSF grants DEB-0717214, DBI-0646356, DBI-9631295, and DBI-9411976.

Helminths Of Squirrels (Sciuridae) From Mongolia, David S. Tinnin, Sumiya Ganzorig, Scott Lyell Gardner

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Two species of ground squirrels, Urocitellus undulatus and Spermophilus alashanicus, were collected and examined for parasites from two localities in Mongolia in 1999. A total of 24 individuals of U. undulatus were examined resulting in a total of six taxa of helminths found, including: Ascaris tarbagan, Physaloptera massino, Streptopharagus kutassi, Anoplocephaloides transversaria, Hymenolepis suslica, and Moniliformis sp. This represents four new species records and an additional host record for the country. Two individuals of S. alashanicus were examined and found to be uninfected.

Helminths Of Small Mammals (Chiroptera, Insectivora, Lagomorpha) From Mongolia With A Description Of A New Species Of Schizorchis (Cestoda: Anoplocephalidae), David S. Tinnin, Scott Lyell Gardner, Sumiya Ganzorig

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Fifty-eight individuals belonging to 10 species of bats, insectivores, and pikas were examined for helminths from 4 collection sites in Mongolia in 1999. Two species of bats (Vespertilio murinus and Eptesicus gobiensis) were infected with a single species of trematode (Plagiorchis vespertilionis), which represents a new record for the country. One individual of E. gobiensis also harbored 1 unidentified filaroid nematode. The acanthocephalan Moniliformis moniliformis was found in the hedgehog Hemiechinus auritus. Cestodes in the genus Catenotaenia and the herein described Schizorchis mongoliensis n. sp. were recovered from pikas belonging to the species Ochotona alpina …
