Wildlife-Cattle Interactions In Northern Michigan: Implications For The Transmission Of Bovine Tuberculosis, Jerry Alan Hill

Michigan Bovine Tuberculosis Bibliography and Database

Bovine tuberculosis (Mycobacterium bovis) was discovered in northern Michigan white-tailed deer (Odocoileus virginianus) in 1994, and has been known to exist in Michigan cattle herds since 1998. Despite efforts to eradicate the disease in cattle, infection and re-infection of farms continues to occur, suggesting transmission among cattle, deer, or other wildlife reservoirs. The goals of this study were to document wildlife activity on farms and evaluate the possible role wildlife play in the ecology of bovine tuberculosis (TB) in Michigan. Visual observations were conducted on farms in a 5-county area of northern Michigan to document direct …

The assignment of the task force was to extend work begun by the National Amphibian Leadership Group. This group, composed of senior USGS scientists, managers, and external authorities, met in Gainesville, Florida, in February 20001. The product of this meeting was a document outlining the framework for a national program to …

Plasmodium Vivax: Allele Variants Of The Mdr1 Gene Do Not Associate With Chloroquine Resistance Among Isolates From Brazil, Papua, And Monkey-Adapted Strains, Juliana Martha Sá, Takashi Nomura, Joana D'Arc Neves, J. Kevin Baird, Thomas E. Wellems, Hernando A. Del Portillo

United States Navy: Publications

We describe here the sequence of the Plasmodium vivax mdr1 gene from 10 different isolates differing in chloroquine sensitivity. The deduced amino acid sequence of PvMDR1 shares more than 70% similarity with other malarial MDR proteins and it displays consensus motifs of an ABC family transporter including two transmembrane domains and two ATP binding cassettes. Similarity and dendrogram analyses revealed that sequences could be grouped according to their geographical origin. Within each geographical group however, no correlation was found between chloroquine resistance and specific mutations.

Yellow Fever Vaccine: An Updated Assessment Of Advanced Age As A Risk Factor For Serious Adverse Events, Alena Y. Khromava, Rachel Barwick Eidex, Leisa H. Weld, Katrin S. Kohl, Robert D. Bradshaw, Robert T. Chen, Martin S. Cetron

Uniformed Services University of the Health Sciences

Since 1996, the scientific community has become aware of 14 reports of yellow fever vaccine (YEL)-associated viscerotropic disease (YEL-AVD) cases and four reports of YEL-associated neurotropic disease (YEL-AND) worldwide, changing our understanding of the risks of the vaccine. Based on 722 adverse event reports after YEL submitted to the U.S. Vaccine Adverse Event Reporting System in 1990–2002, we updated the estimates of the age-adjusted reporting rates of serious adverse events, YEL-AVD and YEL-AND.We found that the reporting rates of serious adverse events were significantly higher among vaccinees aged ≥60 years than among those 19–29 years of age (reporting rate ratio …

United States Army: Publications

The goal of the Malaria Vaccine Program at the Walter Reed Army Institute of Research (WRAIR) is to develop a licensed multi-antigen, multi-stage vaccine against Plasmodium falciparum able to prevent all symptomatic manifestations of malaria by preventing parasitemia. A secondary goal is to limit disease in vaccinees that do develop malaria. Malaria prevention will be achieved by inducing humoral and cellular immunity against the pre-erythrocytic circumsporozoite protein (CSP) and the liver stage antigen-1 (LSA-1). The strategy to limit disease will target immune responses against one or more blood stage antigens, merozoite surface protein-1 (MSP-1) and apical merozoite antigen-1 (AMA-1). The …

Epizootiology Of Sin Nombre And El Moro Canyon Hantaviruses, Southeastern Colorado, 1995–2000, Charles H. Calisher, J. Jeffrey Root, James N. Mills, Joan E. Rowe, Serena A. Reeder, Emily S. Jentes, Kent Wagoner, Barry J. Beaty

United States Department of Agriculture Wildlife Services: Staff Publications

Sin Nombre virus (SNV) is an etiologic agent of hantavirus pulmonary syndrome. To better understand the natural history of this virus we studied population dynamics and temporal pattern of infection of its rodent hosts in southeastern Colorado (USA) from 1995 to 2000. We present evidence for the presence of two hantaviruses, SNV in deer mice (Peromyscus maniculatus) and El Moro Canyon virus in western harvest mice (Reithrodontomys megalotis), at our study sites. Sin Nombre virus appeared only sporadically in deer mouse populations; overall prevalence of antibody to SNV was 2.6%. El Moro Canyon virus was enzootic: …

Population Dynamics Of A Diverse Rodent Assemblage In Mixed Grass-Shrub Habitat, Southeastern Colorado, 1995–2000, Charles H. Calisher, James N. Mills, William P. Sweeney, J. Jeffrey Root, Serena A. Reeder, Emily S. Jentes, Kent Wagoner, Barry J. Beaty

United States Department of Agriculture Wildlife Services: Staff Publications

We followed seasonal and year-to-year population dynamics for a diverse rodent assemblage in a short-grass prairie ecosystem in southeastern Colorado (USA) for 6 yr. We captured 2,798 individual rodents (range, one to 812 individuals per species) belonging to 19 species. The two most common species, deer mice (Peromyscus maniculatus) and western harvest mice (Reithrodontomys megalotis), generally had population peaks in winter and nadirs in summer; several other murid species demonstrated autumn peaks and spring nadirs; heteromyids were infrequently captured in winter, and populations generally peaked in summer or autumn. Interannual trends indicated an interactive effect between …

Potential Consequences Of The Coqui Frog Invasion In Hawaii, Karen H. Beard, William C. Pitt

United States Department of Agriculture Wildlife Services: Staff Publications

The Puerto Rican frog, Eleutherodactylus coqui , has invaded Hawaii and has negatively impacted the state’s multimillion dollar floriculture, nursery and tourist industries; however, little is known about the ecological consequences of the invasion. Using data from Puerto Rico and Hawaii, the authors summarize the potential consequences of the invasion and describe future research needs. It could be predicted that the coqui would reduce the abundance of Hawaii’s endemic invertebrates. However, data suggest that coquis are mostly consuming non-native invertebrates, and not invertebrate pests, such as mosquitoes and termites. Endemic invertebrates are likely to represent a portion of the coqui …

Ctla-4 Signaling Regulates The Intensity Of Hypersensitivity Responses To Food Antigens, But Is Not Decisive In The Induction Of Sensitization, Femke Van Wijk, Sanne Hoeks, Stefan Nierkens, Stef J. Koppelman, Peter Van Kooten, Louis Boon, Leon M.J. Knippels, Raymond Pieters

Department of Food Science and Technology: Faculty Publications

Although food allergy has emerged as a major health problem, the mechanisms that are decisive in the development of sensitization to dietary Ag remain largely unknown. CTLA-4 signaling negatively regulates immune activation, and may play a crucial role in preventing induction and/or progression of sensitization to food Ag. To elucidate the role of CTLA-4 signaling in responses to food allergens, a murine model of peanut allergy was used. During oral exposure to peanut protein extract (PPE) together with the mucosal adjuvant cholera toxin (CT), which induces peanut allergy, CTLA-4 ligation was prevented using a CTLA-4 mAb. Additionally, the effect of …

Etiology Of Oral Disease In View Of Microbial Complexity, Anne C. R. Tanner, Jacques Izard

Department of Food Science and Technology: Faculty Publications

The number of different microorganisms recognized in the oral cavity using molecular methods has more than doubled compared with the number isolated using cultural techniques. This finding necessitates a reevaluation of which species may be pathogens in dental infections. Molecular methods used to determine microbial diversity include broad range target Polymerase Chain Reaction with ‘universal primers,’ and cloning amplicons or denaturing gradient gel electrophoresis to separate DNA fragments before sequencing. These molecular methods have clarified and expanded the taxonomy of oral microbial species. Discrepancies between comprehensive molecular and cultural methods suggest that neither method alone can adequately evaluate associations of …

Genetic variation of human immunodeficiency virus (HIV-1) represents a major obstacle for AIDS vaccine development. To decrease the genetic distances between candidate immunogens and field virus strains, we have designed and synthesized an artificial group M consensus env gene (CON6 gene) to be equidistant from contemporary HIV-1 subtypes and recombinants. This novel envelope gene expresses a glycoprotein that binds soluble CD4, utilizes CCR5 but not CXCR4 as a coreceptor, and mediates HIV-1 entry. Key linear, conformational, and glycan-dependent monoclonal antibody epitopes are preserved in CON6, and the glycoprotein is recognized equally well by sera from individuals infected with different HIV-1 …

The Impact Of Disease In The American White Pelican In North America, Tonie Rocke, Kathryn Converse, Carol Meteyer, Bob Mclean

United States Department of Agriculture Wildlife Services: Staff Publications

Records of reported die-offs of the American White Pelican ( Pelicanus erythrorhynchos ) held by the U.S. Geological Survey National Wildlife Health Center from 1978 through 2003 indicate that type C botulism (caused by Clostridium botulinum ) was the major cause of mortality. In 1996, over 15,000 birds, including 8,500 American White Pelicans, were estimated to have died from type C botulism at the Salton Sea in California. This was the largest documented die-off of any pelican species and was estimated to represent 15-20% of the western metapopulation. This event was also notable in that it was the first time …

Cutting Edge: Cd4+Cd25+ Regulatory T Cells Contribute To Gender Differences In Susceptibility To Experimental Autoimmune Encephalomyelitis, Jay Reddy, Hanspeter Waldner, Xingmin Zhang, Zsolt Illes, Kai W. Wucherpfennig, Raymond A. Sobel, Vijay K. Kuchroo

Jay Reddy Publications

Female B10.S mice are highly resistant to proteolipid protein (PLP) 139–151-induced experimental autoimmune encephalomyelitis (EAE) and depletion of PLP 139–151- reactive CD4+CD25+regulatory T (Treg) cells can slightly increase their EAE susceptibility. Although male B10.S mice are moderately susceptible to EAE, we report that depletion of Treg cells in male B10.S mice before immunization with PLP 139–151 renders them highly susceptible to severe EAE with more CNS neutrophil infiltrates than nondepleted controls. Increased susceptibility is associated with an enhanced PLP 139–151-specific T cell response and greater production of IFN-γ, IL-6, and IL-17. Male CD4+CD25+ effector cells depleted of Treg cells proliferate …

Serologic Survey Of Select Infectious Diseases In Coyotes And Raccoons In Nebraska, Richard Bischof, Douglas G. Rogers

School of Veterinary and Biomedical Sciences: Faculty Publications

To obtain data about select zoonotic and other infectious diseases in free-ranging predators in five ecoregions in Nebraska, sera were collected from 67 coyotes (Canis latrans) and 63 raccoons (Procyon lotor)) from November 2002 through January 2003. For coyotes, antibodies were detected against canine distemper virus (CDV, 61%), Francisella tularensis) (32%), Rickettsia rickettsi) (13%), and flaviviruses (48%). None of the coyote sera had antibodies to Borrelia burgdorferi, Brucella canis), or six serovars of Leptospira interrogans). Because serologic cross-reactivity exists among flaviviruses, 14 sera from flavivirus-positive coyotes were also tested for St. Louis …

Climate Change And Amphibians, P.S. Corn

United States Geological Survey: Staff Publications

Amphibian life histories are exceedingly sensitive to temperature and precipitation, and there is good evidence that recent climate change has already resulted in a shift to breeding earlier in the year for some species. There are also suggestions that the recent increase in the occurrence of El Niño events has caused declines of anurans in Central America and is linked to elevated mortality of amphibian embryos in the northwestern United States. However, evidence linking amphibian declines in Central America to climate relies solely on correlations, and the mechanisms underlying the declines are not understood. Connections between embryo mortality and declines …

Faunal Survey Of Streblid Flies (Diptera: Streblidae) Associated With Bats In Paraguay, Carl W. Dick, Donald Gettinger

Harold W. Manter Laboratory of Parasitology: Faculty Publications

An extensive survey of the ectoparasites infesting bats in Paraguay provides information regarding the taxonomy and host distribution of streblid bat flies at a geographic interface between subtropical and temperate habitats. Five families of bats representing 45 species, including Molossidae (5 genera and 15 species), Natalidae (1 genus and 1 species), Phyllostomidae (11 genera and 15 species), Noctilionidae (1 genus and 2 species), and Vespertilionidae (4 genera and 12 species) were collected from 24 localities across Paraguay and sampled for ectoparasites. In total, 2,467 bat flies were collected, representing 11 genera and 31 nominal species of Streblidae, of which 6 …

Hesperoctenes Fumarius (Hemiptera: Polyctenidae) Infesting Molossus Rufus (Chiroptera: Molossidae) In Southeastern Brazil, Carlos E. L. Esbérard, Andrea C. Jesus, Adarene G. Motta, Helena G. Bergallo, Donald Gettinger

Harold W. Manter Laboratory of Parasitology: Faculty Publications

We analyzed the prevalence. intensity. and medium density of parasitism of Hesperoctenes fumarius infesting Molossus rufus in natural (hollow trees) and anthropogenic roosts (attics) in southeastern Brazil. The prevalence and intensity of infestations were higher in the hollow trees than in the attic roosts. We also noted a relationship between the amount of space available within the roost and the infestation levels of H. fumarius. One advantage of roosting in larger. often manmade. refuges may be the reduction in ectoparasite infestations.

Laelapine Mites (Acari: Laelapidae) Associated With Small Mammals From Amazonas, Brazil, Including A New Species From Marsupials, Donald Gettinger, Fernanda Martins-Hetano, Marcela Lareschi, Jay R. Malcolm

Harold W. Manter Laboratory of Parasitology: Faculty Publications

An intensive survey of ectoparasitic arthropods associated with small mammals in upland forests near Manaus, Brazil, provides information on the taxonomy and host distribution of laelapine mites in the Amazonian Region. We identified 5 genera and 21 species of these mites by comparisonw ith representativem useum specimens, the taxonomic literature, and, when possible, the original type specimens. These mites are host specific, with associations ranging from strict monoxeny (18 species) to oligoxeny (1 species) and pleioxeny (2 species). Marsupials were infested with species of Androlaelaps, echimyid rodents with Tur, and sigmodontine rodents with Gigantolaelaps, Laelaps, and Mysolaelaps. Androlaelaps bergalloi …

A New Species Of Skrjabingylus Petrov, 1927 (Nematoda: Metastrongyloidea) From The Frontal Sinuses Of The Hooded Skunk, Mephitis Macroura (Mustelidae), Ramon A. Carreno, Kathryn E. Reif, Steven A. Nadler

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Skrjabingylus santaceciliae n. sp. is described based on specimens from the frontal sinuses of a hooded skunk, Mephitis macroura, collected from the Area de Conservación Guanacaste, Costa Rica. Skrjabingylus santaceciliae n. sp. differs from the other 5 species in the genus in having pointed spicule tips that lack a rounded or lobed formation and by lacking a prominent distal projection at the tail tip. Morphometric comparisons show that S. santaceciliae n. sp. is much smaller than the only other valid species from Mephitis, Skrjabingylus chitwoodorum Hill, 1939. Likewise, morphometric comparisons also distinguish S. santaceciliae n. sp. from other described Skrjabingylus …

Coevolution And Biogeography Among Nematodirinae (Nematoda: Trichostrongylina) Lagomorpha And Artiodactyla (Mammalia): Exploring Determinants Of History And Structure For The Northern Fauna Across The Holarctic, Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Nematodes of the subfamily Nematodirinae are characteristic components of a Holarctic fauna. the topology of a generic-level phylogenetic hypothesis, patterns of diversity, and geographic distributions for respective nematode taxa in conjunction with data for host occurrence are consistent with primary distributions determined across Beringia for species of Murielus, Rauschia, Nematodirus, and Nematodirella. Ancestral ghosts are represented by Lagomorpha, with evidence for a minimum of 1 host-switching-event and subsequent radiation in the Artiodactyla. Diversification may reflect vicariance of respective faunas along with episodic or cyclical range expansion and isolation across Beringia during the late Tertiary and Quaternary. Secondarily, species …

Possible Recent Range Expansion Of Alcataenia Longicervica (Eucestoda: Dilepididae) Parasitic In Murres Uria Spp. (Alcidae) Into The North Atlantic [Short Communications], Sabir B. Muzaffar, Eric P. Hoberg, Ian L. Jones

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A wide range of helminths has been recorded from murres Uria spp. (Threlfall 1971, reviewed by Hoberg 1984a, Muzaffar & Jones 2004). Of the cyclophyllidean cestodes that parasitize murres, the genus Alcataenia Spasskaya 1971 (Dilepididae) is represented by ten species, eight of which are restricted and specific to the auks; the other two species occur in gulls (Laridae). The intermediate hosts of Alcataenia are euphausiid crustaceans such as species of Thysanoessa (Shimazu 1975), which also form an important dietary component of breeding and wintering murres, particularly Thick-billed Murres Uria lomvia (Gaston & Noble 1985, Birkhead & Nettleship 1987, Elliot et …

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Beringia is the region spanning eastern Asia and northwestern North America that remained ice-free during the full glacial events of the Pleistocene. Numerous questions persist regarding the importance of this region in the evolution of northern faunas. Beringia has been implicated as both a high latitude refugium and as the crossroads (Bering Land Bridge) of the northern continents for boreal mammals. The Beringian Coevolution Project (BCP) is an international collaboration that has provided material to assess the pattern and timing of faunal exchange across the crossroads of the northern continents and the potential impact of past climatic events on differentiation. …

Systematics Of Mesocestoides (Cestoda: Mesocestoididae): Evaluation Of Molecular And Morphological Variation Among Isolates, Kerry A. Padgett, Steven A. Nadler, Linda Munson, Ben Sacks, Walter M. Boyce

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A hypothesis-based framework was used to test if 3 genetic strains of Mesocestoides (clades A, B, and C) are distinct evolutionary lineages, thereby supporting their delimitation as species. For comparative purposes, 3 established cestode species, Taenia pisiformis, Taenia serialis, and Taenia crassiceps were assessed using the same methods. Sequence data from mitochondrial rDNA (12S) and the second internal transcribed spacer of nuclear rDNA (ITS-2) revealed derived (autapomorphic) characters for lineages representing clade A (n = 6 autapomorphies), clade B (n = 4), and clade C (n = 9) as well as T. pisiformis (n = 15) and T. serialis …
