New Records Of Bolivian Mammals, Jorge A. Salazar-Bravo, Mariel Campbell, Sydney Anderson, Scott Lyell Gardner, John L. Dunnum

Harold W. Manter Laboratory of Parasitology: Faculty Publications

We present new records of occurrence and distribution for two species of didelphid marsupials and one species of echimyid rodent. Specimens were obtained from May through August 1991 and June through August 1992 in a study of mammalian diversity of Bolivia, a joint project between the Colección Boliviana de Fauna in La Paz, the Museum of Southwestern Biology (University of New Mexico), the American Museum of Natural History (New York), the Museo “Noel Kempff Mercado” de Historia Natural in Santa Cruz de la Sierra, and the University of California at Davis. This project is an attempt to strength Bolivian collections …

Spiculopteragia Spiculoptera And S. Asymmetrica (Nematoda: Trichostrongyloidea) From Red Deer (Cervus Elaphus) In Texas, Lora G. Rickard, Eric P. Hoberg, Nancy M. Allen, Gary L. Zimmerman, Thomas M. Craig

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Specimens of Spiculopteragia spiculoptera and S. asymmetrica were recovered from the abomasa of five of ten naturally infected red deer (Cervus elaphus) in Texas (USA). Female specimens of Spiculopteragia were present in all five animals. Male specimens of S. spiculoptera and S. asymmetrica were present in one of five and three of five red deer, respectively. Spiculopteragia spiculoptera has not previously been recognized in the United States and the present report constitutes the first records of Spiculopteragia spp. in red deer from North America. It is likely that species of Spiculopteragia have been introduced to North America with …

Enteric Coccidia (Apicomplexa) In The Small Intestine Of The Northern Spotted Owl (Strix Occidentalis Caurina), Eric P. Hoberg, R. J. Cawthorn, O. R. Hedstrom

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Sporulated oocysts (mean dimensions = 13.0 x 10.8 μm) and sporocysts (11.3 x 5.5 μm) of a coccidian resembling Frenkelia sp. or Sarcocystis sp. were present in the lamina propria of the small intestine of a naturally-infected northern spotted owl (Strix occidentalis caurina) collected near Medford, Oregon, USA. Dimensions of these oocysts and sporocysts appear to be considerably smaller than those from other sarcocystid species with avian definitive hosts. Additionally, numerous developmental stages and unsporulated oocysts (mean dimensions 22.8 x 17.8 μm) of a possible species of Isospora also were observed in the intestinal epithelium. This constitutes the …

A New Species Of Linstowia (Cestoda: Anoplocephalidae) From Marsupials In Bolivia, Scott Lyell Gardner, Mariel L. Campbell

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A new species of cestode of the genus Linstowia (Cestoda: Anoplocephalidae) is described from marsupials of the genera Thylamys and Monodelphis. The new species (Linstowia schmidti) differs from L. iheringi Zschokke, 1904, in having a much smaller strobila and reduced number of proglottids, and in the distribution of the eggs in gravid proglottids. In Bolivia, cestodes of the genus Linstowia appear to have a restricted geographic distribution, occurring in marsupials only in southeastern Bolivia near the western margin of the Chaco. This host-parasite association may represent an ecological-historical relict.

Parasites Of The Extinct Shasta Ground Sloth, Nothrotheriops Shastensis, In Rampart Cave, Arizona, Gerald D. Schmidt, Donald W. Duszynski, Paul S. Martin

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Of 7 dissected dung balls of the extinct Shasta ground sloth (Edentata) from Rampart Cave, Arizona, 4 (57%) were found to contain nematode juveniles, helminth eggs, and/or coccidian oocysts. One dung ball was radiocarbon dated at 10,500 ± 180 yr, about the time of ground sloth extinction. It is supposed that the parasites also are extinct. Agamofilaria oxyura n. sp. is proposed for first-stage juveniles of an oxyurid. These juveniles measured 13-20 x 126-198 (16.8 x 159) μm. Strongyloides shastensis n. sp. is reported as first-stage juveniles, some of which clearly are molting. These juvenile worms were 23-27 …

Parasites As Probes For Biodiversity, Scott Lyell Gardner, Mariel L. Campbell

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Cestodes of the genus Linstowia, parasitic in marsupials, show patterns of coevolution and ancient historical-ecological connections. Correlated with the breakup of the austral landmasses (Gondwanaland) of the Neotropical and Australian regions from the Antarctic continent, the age of this host-parasite community is estimated to be between 60 and 70 million years old. Based on the data from the survey of parasites of mammals from throughout Bolivia and from the phylogenetic analysis of the cestodes, we urge the planners of biodiversity preserves in the neotropics to consider the Yungas of Bolivia as a region that supports an ancient ecological community …

Morphology Of The Synlophe And Genital Cone Of Parostertagia Heterospiculum (Trichostrongylidae) With Comments On The Subfamilial Placement Of The Genus, Eric P. Hoberg, J. Ralph Lichtenfels

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The genus Parostertagia is referred to the Cooperiinae with reference to a suite of shared characters of the synlophe and genital cone postulated as derived homologies for the subfamily. The genus has traditionally been relegated to the Graphidiinae or Ostertagiinae, but unique structural attributes of the synlophe and genital cone indicate close affinities with the Cooperiinae. The synlophe of Parostertagia heterospiculum is characterized by a relatively low number of ridges in the cervical zone (16-20 at the excretory pore), a frontal axis of orientation, sequential increase in ridges posteriorly, lateral addition of ridges, minuscule lateral-most ridges and hypertrophy of specific …

Phylogeny, Historical Biogeography, And Ecology Of Anophryocephalus Spp. (Eucestoda: Tetrabothriidae) Among Pinnipeds Of The Holarctic During The Late Tertiary And Pleistocene, Eric P. Hoberg, Ann M. Adams

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Phylogenetic systematic analyses of Anophryocephalus spp. resulted in a single most-parsimonious cladogram (consistency index: 80%). Cladograms for pinniped hosts (phocids and otariids) and Anophryocephalus spp. were highly incongruent, corroborating a hypothesis for colonization as a dominant determinant of parasite diversification. Phoca (Pusa) spp. in the Atlantic basin are postulated as the initial hosts; range expansion for hosts and parasites into the Pacific basin through the Arctic (ca. 3.0-2.5 million years ago) was followed by radiation of Anophryocephalus spp. among Phoca spp. and subsequent colonization of otariids (Eumetopias jubatus as typical hosts; ca. 2.0 million years ago). Host …

Phyletic Coevolution Between Subterranean Rodents Of The Genus Ctenomys (Rodentia: Hystricognathi) And Nematodes Of The Genus Paraspidodera (Heterakoidea: Aspidoderidae) In The Neotropics: Temporal And Evolutionary Implications, Scott Lyell Gardner

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Coevolution was studied in six species of rodents of the genus Ctenomys and their parasitic nematodes of the genus Paraspidodera, collected in Bolivia. Representatives of the families Octodontidae and Caviidae were used as outgroups for the mammals, and nematodes from caviids were used as outgroups of the nematodes from ctenomyids. For the nematodes, quantitative and qualitative morphological characteristics of both males and females and electrophoretic characters of both sexes were used to generate phylogenetic hypotheses of evolutionary relationships of the OTUs occurring in hosts of different species. Concordance estimates of cladograms generated from biochemical-genetic and morphological data of the …

Lists Of Larval Worms From Marine Invertebrates Of The Pacific Coast Of North America, Hilda Lei Ching

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Immature stages of seventy-three digenetic trematodes are listed by their families, marine invertebrate hosts, and localities and then cross listed according to their molluscan hosts. The list contains many new host records, and larval stages of fifteen digenetic trematodes were newly recorded from gastropods from British Columbia and California. A list of immature stages of fourteen cestodes, acanthocephaIans, and nematodes is also included.

Redescription Of Eimeria Escomeli (Rastegaieff, 1930) From Myrmecophaga Tridactyla, And A First Report From Bolivia, Scott Lyell Gardner, Steve Upton, C. R. Lambert, O. C. Jordán

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Eimeria escomeli (Rastegaieff, 1930) Levine and Becker, 1933, is redescribed from the giant anteater, Myrmecophaga tridactyla (L.), from the departamento de La Paz, Bolivia. This is the first report of parasites from M. tridactyla from Bolivia and only the third time that coccidians have been recorded from this host.

Polymorphism Of Eimerian Oocysts Can Be A Problem In Naturally Infected Hosts: An Example From Subterranean Rodents In Bolivia, Scott Lyell Gardner, Donald W. Duszynski

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Since 1986, 364 tuco-tucos (Ctenomys spp.) representing 7 species were collected from 16 major collecting areas representing at least 4 distinct ecological habitats in Bolivia, South America. All were examined for coccidia, and 125 (34%) had oocysts in their feces including 84 of 236 (36%) Ctenomys boliviensis from tropical palm/savanna habitats; 1 of 3 (33%) C. conoveri from a chaco thorn forest; 3 of 7 (33%) C. frater from medium altitude grass habitats; and 6 of 8 (75%) C. lewisi and 31 of 35 (88%) C. opimus from high altitude/puna habitats. None of 3 C. …

Coccidia (Apicomplexa) From Heteromyid Rodents In The Southwestern United States, Baja California, And Northern Mexico With Three New Species From Chaetodipus Hispidus, Paulette L. Ford, Donald W. Duszynski, Chris T. Mcallister

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Fecal samples from 223 heteromyid rodents of 4 genera and 13 species were collected from California, New Mexico, and Texas and from Baja California Norte and Sonora, Mexico. Of these, 84 (38%) were infected with coccidian oocysts; 72 of 84 (86%) infected animals had only 1 species of coccidian. Eleven species of coccidia were identified including 1 cyclosporan and 10 eimerians; the cyclosporan and 2 of the eimerians are described as new species. Sporulated oocysts of Cyclospora angimurinensis n. sp. were subspheroidal, 21.9 x 19.3 (19-24 x 16-22) μm, with sporocysts lemon-shaped, 11.9 x 9.5 (9-15 x 8-11) μm; it …
