The Birds Of St. Matthew Island, Bering Sea, Kevin Winker, Daniel D. Gibson, Arthur L. Sowls, Brian E. Lawhead, Philip D. Martin, Eric P. Hoberg, Douglas Causey

Harold W. Manter Laboratory of Parasitology: Faculty Publications

St. Matthew Island (608 249 N, 1728 429 W) and its small nearby satellites, Hall Island and Pinnacle Rock, are isolated in the north-central Bering Sea. This infrequently visited location occupies a geographic position with a deep Bering Land Bridge history and is in an area of interdigitation of the Old World, New World, and Beringian avifaunas. It is known for its three Beringian endemics, a bird (McKay’s Bunting, Plectrophenax hyperboreus), a small mammal, and a plant. This level of endemism is striking for a high-latitude island. The only previous summary of the avifauna of St. Matthew Island (Hanna …

Ashworthius Patriciapilittae N. Sp. (Trichostrongyloidea: Haemonchinae), An Abosomal Nematode In Odocoileus Virginianus From Costa Rica, And A New Record For The Species Of The Genus In The Western Hemisphere, Eric P. Hoberg, Arthur Abrams, Ramon A. Carreno, J. Ralph Lichtenfels

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A species of Ashworthius is reported for the first time in the Western Hemisphere, and A. patriciapilittae n. sp. is described on the basis of specimens in white-tailed deer Odocoileus virginianus from Costa Rica. Among 8 known species, A. patriciapilittae is morphologically similar to A. tuyenquangi in red muntjac Muntjacus muntjak from northern Vietnam. The synlophe in A. patriciapilittae is composed of 26 ridges in the cervical zone and is continuous to the caudal extremity in males and females. Males are characterized by a complex dorsal ray and narrow trifurcate spicules (351-356 mm long) lacking an ‘‘eyelet,’’ with dissimilar ventral …

Bioorganic Studies In Aids: Synthetic Antifungals Against Pneumocystis Carinii Based On The Multivalency Concept, Langu Peng, Cunxiang Chen, Christian R. Gonzalez, Valeria Balogh-Nair

Publications and Research

We report the syntheses of antifungals containing the novel pharmacophores: oxaziridines, sulfonyloxaziridines, nitrones and nitronyl nitroxides. We hypothesized that multiple copies of the pharmacophore per molecule might be a prerequisite to enhance efficacy against the opportunistic pathogen, Pneumocystis carinii. Therefore structural optimization of the leads was based on this new “multivalency” approach. All bisoxaziridines were inactive, but a trisoxaziridine caused ca. 50% reduction of the number of P. carinii tropozoites, compared to TMP-SMX, and a hexaoxaziridine at 1 µg/ml showed activity comparable to the currently used drug, TMP-SMX. Insertion of three units of the nitronyl nitroxide pharmacophore per molecule afforded …

Control Of Mediterranean Fruit Fly (Medfly) In Backyards, Sonya Broughton, Francis De Lima

Bulletins 4000 -

The Mediterranean fruit fly, Ceratitis capitata (Medfly) is thought to originate from tropical Africa. It is a pest in many areas of the world including Western Australia. It was first detected at Claremont in 1895 and is now found as far south as Esperance and as far north as Derby. The main area of infestation extends from Carnarvon to Bunbury.

Redescriptions Of Haemonchus Mitchelli And Haemonchus Okapiae (Nematoda: Trichostrongyloidea) And Description Of A Unique Synlophe For The Haemonchinae, J. Ralph Lichtenfels, Patricia A. Pilitt, Lynda M. Gibbons, Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty Publications

In the course of a revision of Haemonchus Cobb, 1898 (Nematoda), commonly referred to as large stomach worms, significant new morphological information was discovered that allows the recognition of two species believed for more than 50 years to be synonymous. Both species, Haemonchus mitchelli Le Roux, 1929, from the eland Taurotragus oryx and other African ruminants and H. okapiae van den Berghe, 1937, from the okapi Okapia johnstoni, have a synlophe of 42 ridges, but the synlophe of H. mitchelli is longer than that of H. okapiae. The distal tip of the left spicule of H. mitchelli bears …

Glutathione Levels And Bax Activation During Apoptosis Due To Oxidative Stress In Cells Expressing Wild-Type And Mutant Cystic Fibrosis Transmembrane Conductance Regulator, Thomas Jungas, Iris Motta, Francis Duffieux, Pascale Fanen, Veronique Stoven, David M. Ojcius

All Dugoni School of Dentistry Faculty Articles

Cystic fibrosis is characterized by chronic inflammation and an imbalance in the concentrations of alveolar and lung oxidants and antioxidants, which result in cell damage. Modifications in lung glutathione concentrations are recognized as a salient feature of inflammatory lung diseases such as cystic fibrosis, and glutathione plays a major role in protection against oxidative stress and is important in modulation of apoptosis. The cystic fibrosis transmembrane conductance regulator (CFTR) is permeable to Cl−, larger organic ions, and reduced and oxidized forms of glutathione, and the ΔF508 CFTR mutation found in cystic fibrosis patients has been correlated with impaired glutathione transport …

Human Exposure To Herpesvirus B–Seropositive Macaques, Bali, Indonesia, Gregory A. Engel, Lisa Jones-Engel, Michael A. Schillaci, Komang Gde Suaryana, Artha Putra, Agustin Fuentes, Richard Henkel

All Faculty Scholarship for the College of the Sciences

Herpesvirus B (Cercopithecine herpesvirus 1) has been implicated as the cause of approximately 40 cases of meningoencephalitis affecting persons in direct or indirect contact with laboratory macaques. However, the threat of herpesvirus B in nonlaboratory settings worldwide remains to be addressed. We investigated the potential for exposure to herpesvirus B in workers at a “monkey forest” (a temple that has become a tourist attraction because of its monkeys) in Bali, Indonesia. In July 2000, 105 workers at the Sangeh Monkey Forest in Central Bali were surveyed about contact with macaques (Macaca fascicularis). Nearly half of those interviewed had …

New And Known Species Of Litomosoides (Nematoda: Filarioidea): Important Adult And Larval Characters And Taxonomic Changes, Ricardo Guerrero, Coralie Martin, Scott Lyell Gardner, Odile Bain

Harold W. Manter Laboratory of Parasitology: Faculty Publications

During field surveys in Venezuela, Peru, and French Guiana, species of Litomosoides were recovered from bats and from a didelphid marsupial. Their morphology was studied, giving particular attention to the head and caudal papillae, the spicules (used to distinguish the carinii and sigmodontis groups of Litomosoides), and the microfilariae. Litomosoides wilsoni sp. n. from the short-tailed opossum Monodelphis emiliae is described from Peru; Litomosoides brasiliensis, Litomosoides chandleri, and Litomosoides guiterasi from bats are redescribed, and new hosts are recorded. For the first time, larval stages were recovered from bats (one male and one female fourth-stage larvae of …

Morphometric Analysis Of Nonadult Characters Of Common Species Of American Gordiids (Nematomorpha: Gordioidea), Ben Hanelt, John J. Janovy Jr.

John J. Janovy, Jr. Publications

The nonadult stages, egg strings, eggs, larvae, and cysts of Gordius robustus, Paragordius varius, and Chordodes morgani are described morphometrically. The goal was to document the differences between species and to evaluate the usefulness of morphometrics in species identification. In concert, multivariate analysis of variance (MANOVA) and univariate analysis of variance (ANOVA, a posteriori contrasts) statistical tests demonstrated that each species is morphometrically distinguishable from all others. Additionally, discriminant function analysis indicated that postseptum length, pseudointestine length, and stylet width were the most important variables in the discrimination of species based on larval characters. Finally, differences in oviposition behaviors …

Bolbophorus Damnificus N. Sp. (Digenea: Bolbophoridae) From The Channel Catfish Ictalurus Punctatus And American White Pelican Pelecanus Erythrorhynchos In The Usa Based On Life-Cycle And Molecular Data, Robin M. Overstreet, Stephen S. Curran, Linda M. Pote, D. Tommy King, Charles K. Blend, Walter D. Grater

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The common pathogenic prodiplostomulum metacercaria in the flesh, mostly near the skin, of pond-produced channel catfish Ictalurus punctatus has been demonstrated to be Bolbophorus damnificus Overstreet & Curran n. sp. The catfish acquires the infection from the snail Planorbella trivolvis, the only known first intermediate host, and the species is perpetuated through the American white pelican Pelecanus erythrorhynchos, as confirmed by experimental infections with nestling and dewormed adult pelican specimens in conjunction with molecular data. It differs from the cryptic species Bolbophorus sp., also found concurrently in the American white pelican, by having eggs 123–129 μm rather …

Inhibition Of Apoptosis By Gamma Interferon In Cells And Mice Infected With Chlamydia Muridarum (The Mouse Pneumonitis Strain Of Chlamydia Trachomatis), Jean-Luc Perfettini, Toni Darville, Alice Dautry-Varsat, Roger G. Rank, David M. Ojcius

All Dugoni School of Dentistry Faculty Articles

The effect of gamma interferon (IFN-γ) on apoptosis due to infection by Chlamydia muridarum (the mouse pneumonitis strain of Chlamydia trachomatis) was studied in epithelial cells in culture and in the genital tracts of mice. IFN-γ concentrations that induce the formation of aberrant, persistent chlamydiae inhibit apoptosis due to C. muridarum infection. In cells treated with an IFN-γ concentration that leads to the development of a heterogenous population of normal and aberrant Chlamydia vacuoles, apoptosis was inhibited preferentially in cells that contained the aberrant vacuoles. The inhibitory effect of IFN-γ appears to be due in part to expression of host …

Phylogenetic Analysis Based On 18s Ribosomal Rna Gene Sequences Supports The Existence Of Class Polyacanthocephala (Acanthocephala), Martin Garcia-Varela, Michael P. Cummings, Gerardo Perez-Ponce De Leon, Scott Lyell Gardner, Juan P. Laclette

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Members of phylum Acanthocephala are parasites of vertebrates and arthropods and are distributed worldwide. The phylum has traditionally been divided into three classes, Archiacanthocephala, Palaeacanthocephala, and Eoacanthocephala; a fourth class, Polyacanthocephala, has been recently proposed. However, erection of this new class, based on morphological characters, has been controversial. We sequenced the near complete 18S rRNA gene of Polyacanthorhynchus caballeroi (Polyacanthocephala) and Rhadinorhynchus sp. (Palaeacanthocephala); these sequences were aligned with another 21 sequences of acanthocephalans representing the three widely recognized classes of the phylum and with 16 sequences from outgroup taxa. Phylogenetic relationships inferred by maximum-likelihood and maximum-parsimony analyses showed Archiacanthocephala …

Taking Evoultionary Transitions Seriously, Daniel R. Brooks

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The distinction between reversible and irreversible phenomena in biological information systems provides a basis for distinguishing microevolution from macroevolution. Biological transitions encompass the entire class of irreversible changes in biological systems, including physiological and developmental phenomena. Evolutionary transitions are the subset of biological transitions that have an impact on the quality and quantity of biological information transmitted to future generations. Evolutionary transitions are manifested empirically as macroevolutionary changes, i.e. evolutionary changes that can be detected only through phylogenetic analysis among groups of species sharing a unique common ancestry.

The Development Of A Bluetongue Virus Diagnostic Assay Using Peptides Derived From The Structural Protein Vp7 And Nonstructural Protein Ns2, Yi Lu

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Several peptides derived from viral proteins, VP7 and NS2 of bluetongue virus (BTV), were synthesized for an immunologic detection assay: distinguishing between bluetongue virus infected, vaccinated, and noninfected animals (ruminants) with dot blot analysis. The School of Veterinary Medicine, University of California, Davis, supplied the serum samples from 24 bovine, 18 caprine, 23 ovine. Another 205 bison serum samples were obtained in Utah. The serum samples of BTV-infected animals revealed detectable antibodies to both VP7 and NS2 peptides, whereas vaccinated animals only exhibited antibodies against VP7. Noninfected animals did not display antibody against either viral peptide. These data confirmed the …

Osmosensitive Release Of Neurotransmitter Amino Acids: Relevance And Mechanisms, Herminia Pasantes-Morales, Rodrigo Franco, Lenin Ochoa, Benito Ordaz

School of Veterinary and Biomedical Sciences: Faculty Publications

Hyposmolarity activates amino acid efflux as part of the corrective volume process in a variety of cells. This review discusses the mechanism of amino acid release in brain cells preparations. Results present evidence of substantial differences between the efflux of taurine and that of GABA and glu-tamate, which besides a possible role as osmolytes, have a main function as synaptic transmitters. The differences found concern the efflux time course, the sensitivity to Cl^– channel blockers, the modulation by tyrosine kinases, the influence of PKC and the effect of cytoskeleton disruptive agents. While taurine efflux features fit well with the …

Wallinia Chavarriae N. Sp. (Trematoda: Macroderoididae) In Astyanax Aeneus (Günther, 1860) And Bryconamericus Scleroparius (Regan, 1908) (Osteichthyes: Characidae) From The Área De Conservación Guanacaste, Costa Rica, Anindo Choudhury, Rita Hartvigsen Daverdin, Daniel R. Brooks

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Wallinia chavarriae n. sp. is described from the small-bodied characids Astyanax aeneus and Bryconamericus scleroparius in the Área de Conservación Guanacaste, northwestern Costa Rica. The species differs from W. valenciae in possessing an acetabulum that is smaller than the oral sucker and vitelline follicles that are ovoid or rounded rather than elongate and tubular. Detailed comparison between these two species is handicapped by the less than satisfactory condition of the type and only museum specimen of W. valenciae. Wallinia chavarriae and W. valenciae belong to a subfamily of trematodes, Walliniinae, that arguably includes Creptotrematina spp., Magnivitellum simplex, and …
