Distribution And Disease Prevalence Of Feral Hogs In Missouri, R. Edwin Hartin, Mark R. Ryan, Tyler A. Campbell

United States Department of Agriculture Wildlife Services: Staff Publications

No attempts have been made to document the distribution of feral hogs (Sus scrofa) in Missouri. Also, antibody prevalence for pseudorabies virus and swine brucellosis have not been reported from Missouri. Our objectives were to characterize the current distribution of feral hogs in Missouri and to determine prevalence and distribution of feral hogs with antibodies against selected important diseases. We collected feral hog sighting data both from the public and Missouri Wildlife Services and Missouri Department of Conservation wildlife biologists. We determined prevalence of antibodies against pseudorabies virus, swine brucellosis, tularemia, and classical swine fever. From 2000 to …

The Temporal Program Of Peripheral Blood Gene Expression In The Response Of Nonhuman Primates To Ebola Hemorrhagic Fever, Kathleen H. Rubins, Lisa E. Hensley, Victoria Wahl-Jensen, Kathleen M. Daddario Dicaprio, Howard A. Young, Douglas S. Reed, Peter B. Jahrling, Patrick O Brown, David A. Relman, Thomas W. Geisbert

United States Department of Veterans Affairs: Publications

Background: Infection with Ebola virus (EBOV) causes a fulminant and often fatal hemorrhagic fever. In order to improve our understanding of EBOV pathogenesis and EBOV-host interactions, we examined the molecular features of EBOV infection in vivo.

Results: Using high-density cDNA microarrays, we analyzed genome-wide host expression patterns in sequential blood samples from nonhuman primates infected with EBOV. The temporal program of gene expression was strikingly similar between animals. Of particular interest were features of the data that reflect the interferon response, cytokine signaling, and apoptosis. Transcript levels for tumor necrosis factor-α converting enzyme (TACE)/α-disintegrin and metalloproteinase (ADAM)-17 …

Parasite Findings In Archeological Remains: Diagnosis And Interpretation, Adauto Arajuo, Karl J. Reinhard, Luiz Fernando Ferreira

School of Natural Resources: Faculty Publications

Paleoparasitology has contributed to resolving the debate about the peopling of the Americas and determining the antiquity of human parasite infection. Hookworm (Ancylostomidae) and whipworm (Trichuris trichiura) and other exclusive human intestinal parasites have been recorded in pre-Columbian America. These parasite species originated in pre-hominids and have accompanied humans across continents when people went out of Africa. However, for those human populations that crossed the Bering Land Bridge from Siberia to Alaska, cold climate conditions hampered parasite transmission. Alternative migration routes have been proposed to explain the presence of these parasites in pre-Columbian populations in the Americas. Other …

Spider Mite (Acari: Tetranychidae) Mitochondrial Coi Phylogeny Reviewed: Host Plant Relationships, Phylogeography, Reproductive Parasites And Barcoding, Vera I.D. Ros, Johannes A.J. Breeuwer

Harold W. Manter Laboratory of Parasitology: Library Materials

The past 15 years have witnessed a number of molecular studies that aimed to resolve issues of species delineation and phylogeny of mites in the family Tetranychidae. The central part of the mitochondrial COI region has frequently been used for investigating intra- and interspeciWc variation. All these studies combined yield an extensive database of sequence information of the family Tetranychidae. We assembled this information in a single alignment and performed an overall phylogenetic analysis. The resulting phylogeny shows that important patterns have been overlooked in previous studies, whereas others disappear. It also reveals that mistakes were made in submitting the …

Isotype-Specific Antibody Responses Against Escherichia Coli O157:H7 Locus Of Enterocyte Effacement Proteins In Adult Beef Cattle Following Experimental Infection, G. Bretschneider, E. M. Berberov, Rodney A. Moxley

School of Veterinary and Biomedical Sciences: Faculty Publications

Escherichia coli O157:H7 is an important food-borne pathogen and cause of hemorrhagic colitis and hemolytic uremic syndrome in humans. Cattle are an important reservoir of E. coli O157:H7, in which the organism colonizes the intestinal tract and is shed in the feces. Vaccination of cattle has significant potential as a pre-harvest intervention strategy for E. coli O157:H7; however, basic information about the bovine immune responses to important bacterial colonization factors resulting from infection has not been reported. The serum and fecal IgG and IgA antibody responses of adult cattle to E. coli O157:H7 intimin, translocated intimin receptor (Tir), E. coli …

Low Molecular Weight Protein Tyrosine Phosphatase (Lmw-Ptp) And Its Possible Physiological Functions Of Redox Signaling In The Eye Lens, Kuiyi Xing, Ashraf Raza, Stefan Lofgren, M. Rohan Fernando, Ye-Shih Ho, Marjorie F. Lou

School of Veterinary and Biomedical Sciences: Faculty Publications

Low molecular weight protein tyrosine phosphatase (LMW-PTP) was cloned from human lens epithelial B3 cells (HLE B3) and the recombinant enzyme was purified to homogeneity. The pure enzyme reacted positively with anti-LMW-PTP antibody, displayed tyrosine-specific phosphatase activity and was extremely sensitive to H2O2. The inactivated LMW-PTP could be regenerated by thioltransferase (TTase)/GSH system as demonstrated by both activity assay and by mass spectrometry (MS). The MS study also showed that an intramolecular disulfide bond was formed between C13 and C18 at the active site, and was reduced by the TTase/GSH system. The putative role of LMW-PTP in regulating platelet derived …

Invasive Rats And Bubonic Plague In Northwest Uganda, Jeff N. Borchert, Jeff J. Mach, Timothy J. Linder, Asaph Ogen-Odoi [Deceased, In Memoriam], Santos Angualia

Managing Vertebrate Invasive Species

Major introductions of roof rats (Rattus rattus) likely occurred in the ports of East Africa during the Third Plague Pandemic in the late 1800’s. Transport via trains, boats, and trucking likely introduced this species to inland areas of East Africa, ultimately including Northwest Uganda. Historic plague outbreaks occurred during the early part of the 20th century and continue to cause a human disease burden in the West Nile region of NW Uganda via the bubonic, septicemic, and pneumonic forms. Four field sites in this area were trapped to determine the rodent species composition in commensal and peridomestic areas …

The Path To Eradication Of The Gambian Giant Pouched Rat In Florida, Richard Engeman, Gary W. Witmer, Jean B. Bourassa, John W. Woolard, Bernice Constantin, Parker T. Hall, Scott Hardin, Neil D. Perry

Managing Vertebrate Invasive Species

A thriving population of Gambian giant pouched rats became established on Grassy Key, a 550-ha island in Florida, following escape(s) from an exotic pet breeder. After existence of the population was verified, computer models indicated that Gambian giant pouched rats could successfully invade a large portion of North America if they reached the mainland. This largest of rat species is highly prolific, and its dispersal to the mainland could result in substantial negative impacts to agriculture, environment, and wildlife. Additionally, Gambian giant pouched rats are known vectors of a variety of diseases transmissible to humans and livestock. The first action …

The Failed Regulatory System For Animal Imports Into The United States – And How To Fix It, Peter Jenkins

Managing Vertebrate Invasive Species

This paper provides a synopsis of the Defenders of Wildlife report entitled Broken Screens: The Regulation of Live Animal Imports in the United States, released in August 2007. That report assessed the complex federal system for regulating live wild animal imports as applied to the 2,241 non-native species that were identified in United States Fish and Wildlife Service records as being imported between 2000 and 2004, inclusive. The report describes the “coarse risk screening” conducted for those species by searching the scientific literature and United States and international databases. If one or more reliable sources indicated a species was …

European Starlings: A Review Of An Invasive Species With Far-Reaching Impacts, George M. Linz, H. Jeffrey Homan, Shannon M. Gaulker, Linda B. Penry, William J. Bleier

Managing Vertebrate Invasive Species

The introduction of European starlings (Sturnus vulgaris) in New York City in 1890 and 1891 resulted in their permanent establishment in North America. The successful occupation of North America (and most other continents as well) has earned the starling a nomination in the Top 100 list of ‘Worlds Worst’ invaders. Pimentel et al. (2000) estimated that starling damage to agriculture crops in the United States was $800 million yearly, based on $5/ha damage. Starlings may spread infectious diseases that sicken humans and livestock, costing nearly $800 million in health treatment costs. Lastly, starlings perhaps have contributed to the …

Environmental And Economic Costs Of Vertebrate Species Invasions Into The United States, David Pimental

Managing Vertebrate Invasive Species

The more than 50,000 species of plants, animals, and microbes introduced into the United States (US) cause more extinction of native species than most any other threat and cause more than $120 billion in damages and control costs each year. In particular, invasive mammals and birds cause major environmental and economic losses totaling about $46 billion per year in damage and control costs per year. Feral cats, rats, and hogs are especially serious pests. Pigeons and starlings are a major concern in cities and US agriculture. Prevention and management strategies will be discussed.

Population Ecology And Some Potential Impacts Of Emerging Populations Of Exotic Parrots, Douglas E. Runde, Will C. Pitt, J. T. Foster

Managing Vertebrate Invasive Species

Parrots have been transported around the world since the 1400s and about 44 species have established populations outside of their native ranges. At least 70% of these introduced species were identified as potential agricultural pests, compared to only 15% of all parrot species. At least 74 exotic psittacines have been reported in the wild in the United States, but only nine species were considered established. Since 1990, 24 psittacine species have been sighted in the wild in Hawai`i, about 21 species regularly occur on the main islands and at least five appear established. Past history of successful introduction, recent status …

Developing A Decision Support System For Improving Possum Control Planning, Bruce Warburton, Jim Coleman, Mark Fuglestad, James Dietrich

Managing Vertebrate Invasive Species

Brushtail possums are a major invasive pest in New Zealand. A decision support system (DSS) has been developed to enable those involved in operational planning or delivery of possum control to access available relevant knowledge when making operational decisions. The DSS comprises checklists that ensure users consider relevant constraints and issues, a database of best-practice information on possum control, and an “expert” system that recommends actions based on information provided by the user.

Species-Specific Visitation And Removal Of Baits For Delivery Of Pharmaceuticals To Feral Swine, Tyler A. Campbell, David B. Long

United States Department of Agriculture Wildlife Services: Staff Publications

Within the domestic swine industry there is growing trepidation about the role feral swine (Sus scrofa) play in the maintenance and transmission of important swine diseases. Innovative disease management tools for feral swine are needed. We used field trials conducted in southern Texas from February to March 2006 to compare species-specific visitation and removal rates of fish-flavored and vegetable-flavored baits with and without commercially available raccoon (Procyon lotor/) repellent (trial 1) and removal rates of baits deployed in a systematic and cluster arrangement (trial 2). During trial 1, 1) cumulative bait removal rates after four nights …

Analysis Of Risks Of Interbasin Biota Transfers Potentially Linked To System Failures In The Northwest Area Water Supply Project, Greg Linder

United States Geological Survey: Publications

Through the Garrison Diversion Unit Reformulation Act of 1986, the Municipal, Rural and Industrial Water Supply (MR&I) program was authorized by the US Congress on May 12, 1986. This act authorized the appropriation of $200 million of Federal funds for the planning and construction of water supply facilities throughout North Dakota. The Northwest Area Water Supply (NAWS) project was developed as a result of this authorization and was initiated in November 1987. NAWS is a bulk water distribution system that will service local communities and rural water systems in 10 counties in northwestern North Dakota, including the community of Minot …

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Information concerning mites found in the hair of wild mammals of North America north of Mexico is summarized for records accumulated since a similar paper was published by Whitaker and Wilson in 1974. Chiggers, ticks and species that burrow into or under the skin are generally excluded although follicle-inhabiting mites are included. Included are lists a) of the mites organized taxonomically, b) hosts from which each species has been reported, and c) states and provinces citing references for each separate record.

The Distribution Of Sexually-Transmitted Human Papillomaviruses In Hiv Positive And Negative Patients In Zambia, Africa, Christopher Ngandwe, John Lowe, Paula J. Richards, Lara Hause, Charles Wood, Peter C. Angeletti

Nebraska Center for Virology: Faculty Publications

Background: Human Papillomaviruses (HPV) are double-stranded DNA viruses, considered to be the primary etiological agents in cervical intraepithelial neoplasias and cancers. Approximately 15–20 of the 40 mucosal HPVs confer a high-risk of progression of lesions to invasive cancer. In this study, we investigated the prevalence of sexually transmitted HPVs in Human Immunodeficiency Virus (HIV) positive and negative patients in Zambia, Africa. The rate of high-risk HPV genotypes worldwide varies within each country. Thus, we sought to investigate the rates of HPV infection in sub-Saharan Africa and the potential role of HIV in affecting the HPV genotype distribution.

Methods: This retrospective …

Wildlife Disease Management: An Insurmountable Challenge?, Scott E. Henke, Alan M. Fedynich, Tyler A. Campbell

United States Department of Agriculture Wildlife Services: Staff Publications

Wildlife biologists are increasingly being thrust onto the frontlines of wildlife disease management and surveillance in the United States. For example, biologists now routinely engage in oral vaccination of wildlife [e-g., Oral Rabies Vaccination Programs (QRVPs)] and collect specimens for both diagnostic purposes and disease surveillance or monitoring (e.g., avian influenza in migratory bids). For many, these responsibilities are novel compared to the more traditional roles of population estimation. habitat manipulation, and formulation of harvest recommendations. Wildlife disease investigation and management, in reality, we in their infancy compared with disciplines of human and domestic animal disease management. The recent focus …

A New Species Of Dipetalonema (Filarioidea: Onchocercidae) From Ateles Chamek From The Beni Of Bolivia, Juliana Notarnicola, F. Agustin Jimenez-Ruiz, Scott Lyell Gardner

Harold W. Manter Laboratory of Parasitology: Faculty Publications

We describe a new species of Dipetalonema occurring in the body cavity of Ateles chamek (Humboldt, 1812) from north-central Bolivia. Morphologic characters serving to separate Dipetalonema yatesi n. sp. from known forms include a vagina vera with a simple tube and thin walls and a left spicule, which possesses a handle shorter than the lamina (ratio 2.7); the latter displays an anterior membranous alae similar in length to the terminal flagellum, a distal extremity of the left spicule within a simple hook and a membrane, phasmids at the basis of the lappets, and heterogeneous muscles occupying the whole cavity. Dipetalonema …

Coyotes As Sentinels For Monitoring Bovine Tuberculosis Prevalence In White-Tailed Deer, Todd C. Atwood, Kurt C. Vercauteren, Thomas J. Deliberto, Holly J. Smith, Justin S. Stevenson

United States Department of Agriculture Wildlife Services: Staff Publications

Mycobacterium bovis, the causative agent of bovine tuberculosis (bTB), is endemic in free-ranging white-tailed deer (Odocoileus virginianus) in 5 counties (Alcona, Alpena, Montmorency, Oscoda, and Presque Isle) in the northeastern Lower Peninsula of Michigan, USA. The presence of a wildlife reservoir of tuberculosis in Michigan and the incidence of bTB in cattle (Bos taurus) resulted in Michigan losing its bTB accredited-free status. Subsequent wildlife surveillance programs identified relatively high disease prevalence in coyotes (Canis latrans), generating interest in their potential to serve as a sentinel species to detect bTB prevalence in white-tailed deer. …

Fence-Line Contact Between Wild And Farmed White-Tailed Deer In Michigan: Potential For Disease Transmission, Kurt C. Vercauteren, Michael J. Lavelle, Nathan W. Seward, Justin W. Fischer, Gregory E. Phillips

United States Department of Agriculture Wildlife Services: Staff Publications

Interactions between wild and farmed white-tailed deer (Odocoileus virginianus) along perimeter fences may play a role in the transmission of diseases like bovine tuberculosis and chronic wasting disease. However, no study has evaluated direct contact between wild and farmed deer through fences. We used animal-activated cameras to estimate rates of interaction between wild and farmed deer at 6 high-fenced commercial white-tailed deer farms in Michigan, USA, during October 2003 to January 2005. We recorded only 2 direct, naso-oral contacts between wild and farmed deer during >77,000 hours of camera monitoring. We documented little direct contact between wild and …

Fence-Line Contact Between Wild And Farmed Cervids In Colorado: Potential For Disease Transmission, Kurt C. Vercauteren, Michael J. Lavelle, Nathan W. Seward, Justin W. Fischer, Gregory E. Phillips

United States Department of Agriculture Wildlife Services: Staff Publications

Direct and indirect contact between wild and farmed cervids along perimeter fences may play a role in transmission of diseases like chronic wasting disease (CWD), but no studies have quantified such interactions. At 9 high-fenced commercial elk (Cervus elaphus) farms in Colorado, USA, during October 2003 to January 2005, we used animal-activated video to estimate rates of fence-line use by wild cervids, rates of direct contact between farmed and wild cervids, and probability of direct contact when wild cervids were present. We recorded 8-foldmore wild elk per unit time than mule deer (Odocoileus hemionus) at fence …
