Two New Species Of Litomosoides (Nemata: Onchocercidae) From Ctenomys Opimus (Rodentia: Ctenomyidae) On The Altiplano Of Bolivia, Sara V. Brant, Scott Lyell Gardner

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Two filarioid nematodes, Litomosoides andersoni n. sp. and Litomosoides ctenomyos n. sp. (Nemata: Onchocercidae), are described from the mesenteries of the subterranean rodent Ctenomys opimus (Rodentia: Hystrichognathi) collected on the altiplano of Bolivia. Specimens collected near Rancho Huancaroma (Oruro Dept.) in 1984 and 1986 can be recognized as undescribed by the structures of the spicules and stoma and the shape of the ovijector. This record represents the first time members of the genus Litomosoides have been recovered from rodents of the family Ctenomyidae; this also represents the first published report of these nematodes from mammals in Bolivia.

Cultural, Historical, And Subcultural Contexts Of Adolescence: Implications For Health And Development, Lisa J. Crockett

Department of Psychology: Faculty Publications

Although clearly influenced by biological and psychological growth, adolescent development is also molded by the social and cultural context in which it occurs. As the transition from childhood to adulthood, adolescence is closely tied to the structure of adult society, and the expectations for youth during this period reflect, in important ways, the skills and qualities deemed important for success in adult roles (Benedict, 1937; Havighurst, 194811972). Furthermore, prevailing demographic, economic, and political conditions determine the adult occupational and social roles to which young people can aspire, as well as the access to and competition for those roles (Elder, 1975). …

Gregarina Triboliorum (Eugregarinida: Gregarinidae) N. Sp. From Tribolium Confusum And Resolution Of The Confused Taxonomic History Of Gregarina Minuta Ishii, 1914, Stephanie Watwood, John J. Janovy Jr., Erica Peterson, Mary Ann Addison

John J. Janovy, Jr. Publications

The septate gregarine parasites of flour beetles (Tribolium spp.) include Gregarina minuta Ishii, 1914, a relatively small species in which both primite and satellite possess an obvious protomerite, and a larger species that lacks the satellite protomerite. The latter species has been placed in the genera Didymophyes and Hirmocystis by various authors, but studies reported here demonstrate that this species, herein described as Gregarina triboliorum, exhibits early pairing and produces oocyst chains, both characteristics of the genus Gregarina. The oocysts of this new species are described for the first time. In addition, experimental infections using oocysts from …

Eimeria From Bats Of The World: Two New Species From Myotis Spp. (Chiroptera: Vespertilionidae), Damien T. Scott, Donald W. Duszynski

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Between 1986 and 1995, 548 fecal samples were collected from 41 species of bats (Molossidae, Mormoopidae, Phyllostomidae, Thyropteridae, and Vespertilionidae) from New Mexico, California, Baja California Sur (Mexico), and Bolivia. Of these, the feces of 28 (5%) bats, including Antrozous pallidus, Myotis ciliolabrum, Myotis lucifugus, and Myotis yumanensis (Vespertilionidae), contained oocysts representing at least 3 species of Eimeria. A new species of eimerian from M. lucifugus (3/27, 11%) and M. yumanensis (8/70, 11%) is described. Sporulated oocysts are ellipsoidal, 22.3 × 14.8 (18-25 × 13-16) μm with micropyle (~2 μm) and polar granules (1-4), but an …

Eimeria (Protozoa: Eimeriidae) From North American Sciurids, Glaucomys Sabrinus And Tamias Townsendii: With A Description Of A New Species, Claire A. Fuller, Donald W. Duszynski

Harold W. Manter Laboratory of Parasitology: Faculty Publications

From 1990 to 1991, 11 northern flying squirrels, Glaucomys sabrinus, and 30 Townsend's chipmunks, Tamias townsendii, were live-trapped, marked, and released in MacDonald Forest, Benton Co., Oregon and their feces at each capture examined for the presence of coccidian parasites. Two eimerians were found in G. sabrinus: Eimeria doreyi and a second species we describe here as new. One species, Eimeria vilasi, was identified from T. townsendii. Sporulated oocysts of the new eimerian are strongly ellipsoidal, pointed at 1 end, and are 47.2 × 25.0 (41-52 × 22-31) μm with ovoidal sporocysts, 19.0 × 10.5 …

The Canadian Cooperative Wildlife Health Centre And Surveillance Of Wild Animal Diseases In Canada, Volume 38, May 1997, Frederick A. Leighton, Gary A. Wobeser, Ian K. Barker, Pierre-Yves Daoust, Daniel Martineau

Canadian Cooperative Wildlife Health Centre: Newsletters and Publications

The Canadian Cooperative Wildlife Health Centre (CCWHC) was established in 1992 as an organization among Canada's 4 veterinary colleges, with a mandate to apply veterinary medicine to wildlife management and conservation in Canada. A major function of the CCWHC is nation-wide surveillance of wild animal diseases. Disease surveillance is conceived as consisting of 4 different activities: detection, diagnosis, information management, and use of information. In the CCWHC surveillance program, detection of disease is carried out by a wide range of professional and avocational field personnel, and much effort is expended to stimulate and support this activity. Diagnosis is done by …

A Guideline For The Preparation Of Species Descriptions In The Eimeriidae, Donald Duszynski, Patricia G. Wilber

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Members of the suborder Eimeriina (phylum Apicomplexa: class Sporozoea: order Eucoccidiorida) have complex 1 or 2 host life cycles that involve endogenous development in the tissues of vertebrates or invertebrates and exogenous development in an oocyst, usually outside the host(s). Because tissue stages are logistically difficult or even impossible to obtain in natural (wild) host-parasite systems, the vast majority (> 98%) of species in this parasite complex are known only from the structure of their sporulated oocyst. Unfortunately, the quality of these species descriptions is uneven because no guidelines are available for workers in the field to follow. Here we …

A New Coccidian From Acomys Cahirinus Desmarest, 1819, From Evolution Canyon, Lower Nahal Oren, Mount Carmel, Israel, Lee Couch, Leon Blaustein, Donald W. Duszynski, Georgy Shenbrot, Eviatar Nevo

Harold W. Manter Laboratory of Parasitology: Faculty Publications

In 1994, fresh fecal samples were collected and examined for coccidian parasites from 43 spiny mice (Acomys cahirinus) and from 60 wood mice (Apodemus mystacinus). The 2 genera of rodents inhabit an area in Lower Nahal Oren, Mount Carmel, Israel, known as Evolution Canyon, which consists of opposite-facing slopes that are geologically identical, but micro-climatically very different. Acomys cahirinus is found primarily on the warmer and drier south-facing slope (SFS), whereas A. mystacinus primarily inhabits the cooler and wetter north-facing slope (NFS). None of the samples from the A. mystacinus contained coccidia, but 6 of 43 …

Susceptibility To Taura Syndrome Virus Of Some Penaeid Shrimp Species Native To The Gulf Of Mexico And The Southeastern United States, Robin M. Overstreet, Donald V. Lightner, Ken W. Hasson, Stacey Mcilwain, Jeffrey M. Lotz

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Experimental studies demonstrated that Penaeus setiferus, but not Penaeus aztecus or Penaeus duorarum, could be killed by Taura syndrome virus (TSV). However, specimens of P. setiferus that survived infection and both P. aztecus and P. duorarum at least 79 days postexposure that did not demonstrate gross signs of infection were shown to harbor virus by bioassay using Penaeus vannamei, a highly susceptible target host. Consequently, all three of those penaeids native to the southeast United States can serve as carriers or reservoir hosts of TSV without necessarily exhibiting disease. Infections in P. setiferus took longer to cause …

Phylogenetic Analysis Of Nematodes Of The Genus Pratylenchus Using Nuclear 26s Rdna, Luma Al-Banna, Valerie M. Williamson, Scott Lyell Gardner

Harold W. Manter Laboratory of Parasitology: Faculty Publications

We used nucleotide sequences of the large subunit ribosomal genes (26S rDNA) to examine evolutionary relationships among species of the genus Pratylenchus (Order: Tylenchida, Family: Pratylenchidae), commonly known as root-lesion nematodes. Ten species of Pratylenchus were studied including, P. penetrans, P. crenatus, P. minyus, P. vulnus, P. thornei, P. musicale, P. coffeae, P. bexincisus, P. scribneri, and P. brachyurus. The species Hirschmanniella belli, Meloidogyne javanica, Heterorhabditis bacteriophora, Nacobbus eberruns, Radopholus similis, and Xiphinema index were used as outgroups. Based on parsimony analyses of approximately 307 …

Myxobolus Mississippiensis N. Sp. (Myxosporea) From Gills Of Lepomis Macrochirus In Mississippi, David K. Cone, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Myxobolus mississippiensis n. sp. is described from gill lamellae of the bluegill (Lepomis macrochirus) inhabiting the Pascagoula River System, Mississippi. Fresh spores measure 16.4-18.7 μm long, 3.9-6.2 μm wide, and 4.7-6.2 μm thick. Spore width to length ratio is 1:3.2. Polar capsules are 5.5-7.8 μm long and 1.5-2.3 μm wide, with 9-10 filament coils that when extruded measure 42.1 ± 4.2 μm. This parasite is unique among known species of Myxobolus,/i> in having spores that are lenticular in frontal view.
