Herpes Simplex Virus Type 2 Induces Rapid Cell Death And Functional Impairment Of Murine Dendritic Cells In Vitro, Clinton J. Jones, M. Fernandez, K. Herc, L. Bosnjak, M. Miranda-Saksena, R. A. Boadle, A. Cunningham

School of Veterinary and Biomedical Sciences: Faculty Publications

Dendritic cells (DC) are critical for stimulation of naive T cells. Little is known about the effect of herpes simplex virus type 2 (HSV-2) infection on DC structure or function or if the observed effects of HSV-1 on human DC are reproduced in murine DC. Here, we demonstrate that by 12 h postinfection, wild-type (wt) HSV-2 (186) abortively infected murine bone marrow-derived DC and induced early cell death compared to UV-inactivated HSV-2 or mock-infected DC. HSV-2-induced loss of DC viability was more rapid than that induced by HSV-1 and was due, in part, to apoptosis, as shown by TEM, caspase-3 …

First Report Of A Species Of Folliculovarium Gu & Shen, 1983 (Bucephalidae: Prosorhynchinae) From European Marine Waters, With The Description Of F. Mediterraneum N. Sp., Pierre Bartoli, Robin M. Overstreet, David I. Gibson

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Folliculovarium mediterraneum n. sp. is described and figured in detail from the intestine of the Mediterranean moray eel Muraena helena (Muraenidae) in the Scandola Nature Reserve, off Corsica in the western Mediterranean. This new species closely resembles F. gymnothoracis Gu & Shen, 1983 and F. xishaense Gu & Shen, 1983 from marine fishes off China, but it may differ from both in not having specialized circum-rynchal spines. It differs from the former by having slightly larger eggs and a longer esophagus, and from F. xishaense by having tegumental spines, a longer esophagus, and a nonrelated host (an eel rather than …

Taxonomic Revision Of Rhinebothroides (Eucestoda: Tetraphyllidea: Phyllobothriidae), Parasites Of Neotropical Freshwater Stingrays (Rajiformes: Myliobatoidei: Potamotrygonidae), Fernando P.L. Marques, Daniel R. Brooks

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Extensive new collections of specimens of Rhinebothroides spp. from a wide range of Neotropical freshwater potamotrygonid stingrays in numerous localities permitted critical evaluation of the validity of the 7 nominal species in the genus. Some qualitative characters previously used in the taxonomy of this group are highly variable within and among populations, and most morphometric and meristic characters thought to have taxonomic value for this group overlapped among several previously defined nominal species. Characters that were consistent throughout populations and that clearly define morphotypes supported recognition of four species: R. freitasi (syn. R. circularisi and R. venezuelensis), R. glandularis …

Lessons From A Quiet Classic, Daniel R. Brooks

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Parasitology has a rich tradition of studies linking taxonomy, ecology, and life cycles and development. This tradition has produced an enormous amount of empirical evidence demonstrating that parasites form highly integrated reproductive-developmental-ecological systems that are highly persistent through space and time. As well, phylogenetic studies of parasites, especially of parasitic platyhelminths, represent 1 of the most progressive areas of systematic biology. Consequently, parasitologists should be at the forefront of research in evolutionary developmental biology (evo-devo) and integrative biology, and parasite systems should be model systems of choice for those research programs. Species of the digenean, Alloglossidium, provide a superb …

A New Species Of Syncuaria Gilbert, 1927 (Nematoda: Acuarioidea: Acuariidae) In The Wood Stork, Mycteria Americana L. (Aves: Ciconiiformes: Ciconiidae) From The Área De Conservación Guanacaste, Costa Rica, Luping Zhang, Daniel R. Brooks, Douglas Causey

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Syncuaria mycteriae n. sp. (Nematoda: Acuarioidea) was collected under the lining of the gizzard of a wood stork, Mycteria americana L., from the Área de Conservación Guanacaste, Costa Rica. The new species can be distinguished from all known species of Syncuaria by having irregular dotted ornamentations on the caudal alae of males, a complex distal end of the left spicule comprising three protuberances, and a spicule ratio of 1:9.3. Preliminary phylogenetic analysis of 11 Syncuaria spp. based on 9 morphological characters produced two equally parsimonious cladograms with a consistency index of 85%, differing only in the placement of S. hargilae …

Two Species Of Acuaria Bremser, 1811 (Nematoda: Acuarioidea: Acuariidae) In Passerine Birds From The Área De Conservación Guanacaste, Costa Rica, Luping Zhang, Daniel R. Brooks, Douglas Causey

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Two species of Acuaria were collected from passerine birds from the Área de Conservación Guanacaste, Costa Rica. Acuaria mayori Lent, Freitas and Proenca, 1945, was collected from Myiarchus nuttingi. Specimens from Costa Rica differ from the original description by having a spicule ratio of 1:1.5-1.7 versus 1:1.43-1.47, as well as shorter spicules and female tails. Acuaria wangi n. sp. in Hylophylax naevioides and Gymnopithys leucaspis resembles A. alii, A. crami, A. cyanocitta, A. minuta, A. pattoni, and A. cissae by having cordons extending posteriorly to the anterior portion of the glandular esophagus.

Shepherd, Walter Brandt, Philip K. Russell

Michael Meagher Publications

Hookworm infection is one of the most important parasitic infections of humans, possibly outranked only by malaria as a cause of misery and suffering. An estimated 1.2 billion people are infected with hookworm in areas of rural poverty in the tropics and subtropics. Epidemiological data collected in China, Southeast Asia, and Brazil indicate that, unlike other soil-transmitted helminth infections, the highest hookworm burdens typically occur in adult populations, including the elderly. Emerging data on the host cellular immune responses of chronically infected populations suggest that hookworms induce a state of host anergy and immune hyporesponsiveness. These features account for the …

Aspidoderid Nematodes From Bolivian Armadillos, With The Description Of A New Species Of Lauroia (Heterakoidea: Aspidoderidae), Scott Lyell Gardner, F. Agustin Jimenez-Ruiz

Harold W. Manter Laboratory of Parasitology: Faculty Publications

One nine-banded armadillo (Dasypus novemcinctus) and 1 yellow armadillo (Euphractus sexcinctus) were necropsied in the field during an expedition to collect parasites of mammals in Bolivia. A total of 205 Aspidodera binansata Railliet and Henry, 1913 (Heterakoidea: Aspidoderidae), and 40 specimens of Lauroia bolivari n. sp. (Heterakoidea: Aspidoderidae) were recovered from the cecum and large intestines of D. novemcinctus and E. sexcinctus. Aspidodera esperanzae Fujita et al., 1995, is proposed as a junior synonym of A. binansata based on the structure of the cordons on the hood. Lauroia bolivari n. sp. has an undercut cephalic …

Brooks, Douglas Causey

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A new species of digenean found in the intestines of the steely-vented hummingbird Amazilia saucerrottei and the yellow-olive flycatcher Tolmomyias sulphurescens from the Área de Conservación Guanacaste, Guanacaste, Costa Rica, resembles members of the Prosthogonimidae in having a highly lobate ovary; an elongate cirrus sac containing the cirrus, pars prostatica, and internal seminal vesicle; no external seminal vesicle; two fields of extracecal vitelline follicles restricted to the area between the intestinal bifurcation and testes; and uterine loops occupying all available space in the hind body. The new species differs from all other members of the family in having genital pores …

Bakkeius Moragai N. Gen. Et N. Sp. And Pojmanskia Riosae N. Gen. Et N. Sp. (Trematoda: Digenea: Brachylaimoidea) In Birds From The Área De Conservación Guanacaste, Costa Rica, David Zamparo, Daniel R. Brooks, Douglas Causey

Harold W. Manter Laboratory of Parasitology: Faculty Publications

We describe two new species of leucochloridiid-like brachylaimoid digeneans parasitizing a variety of birds in the Área de Conservación Guanacaste, Costa Rica, each of which we assign to a new genus. According to Pojmanska's (Pojmanska, T. 2002a. Superfamily Brachylaimoidea Joyeux & Foley, 1930. In Keys to the Trematoda, D. I. Gibson, A. Jones, and R. A. Bray [eds.]. CAB International and The Natural History Museum, London, U.K., p. 31-36.) key for the Brachylaimoidea, we are unable to place either species in any family. One species most closely resembles members of Leucochloridium by having well-developed suckers, lacking an esophagus, and …

Tinamutrema Canoae N. Gen. Et N. Sp. (Trematoda: Digenea: Strigeiformes: Brachylaimidae) In Crypturellus Cinnamomeus (Aves: Passeriformes: Tinamidae) From The Área De Conservación Guanacaste, Costa Rica, David Zamparo, Daniel R. Brooks, Douglas Causey

Harold W. Manter Laboratory of Parasitology: Faculty Publications

We propose Tinamutrema as a new genus for Brachylaima centrodes (Braun, 1901) Dollfus, 1935 and for T. canoae, as a new species inhabiting tinamus in the Área de Conservación Guanacaste, Costa Rica. Specimens from Costa Rica resemble B. centrodes in having an elongate body, pretesticular genital pore and terminal genitalia, intercecal uterine loops occupying all available space between the anterior testis and the intestinal bifurcation, an oral sucker width:pharynx width ratio of approximately 1:0.55, an oral sucker:ventral sucker width ratio of approximately 1:1, and vitelline follicles extending into the forebody closer to the pharynx than to the anterior margin …

Neohaematotrephus Arayae N. Sp. (Digenea: Echinostomiformes: Cyclocoelidae) In Jacana Spinosa (Aves: Charadriiformes: Jacanidae) From The Área De Conservación Guanacaste, Costa Rica, David Zamparo, Daniel R. Brooks, Douglas Causey, Beatriz Rodriguez

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Specimens of a species of cyclocoelid digenean inhabiting Jacana spinosa from the Área de Conservación Guanacaste, Costa Rica, most closely resemble ,i>Haematotrephus facioi (Brenes and Arroyo, 1962) Yamaguti, 1971, in the same host from Aranjuez, Puntarenas Province, Costa Rica, in having confluent vitelline follicles posteriorly, diagnostic of Neohaematotrophus, and in pharynx length, ovary width, and cirrus sac on the sinistral side. The new species is also highly similar in appearance to H. gendrei Dubois, 1959, also inhabiting a jacanid (from West Africa), which has vitelline follicles confluent posteriorly, and extending anteriorly to the intestinal bifurcation and genital pore …

The Economics Of Managing Wildlife Disease, Richard D. Horan, Christopher A. Wolf

Michigan Bovine Tuberculosis Bibliography and Database

The spread of infectious disease among and between wild and domesticated animals has become a major problem worldwide. Upon analyzing the dynamics of wildlife growth and infection when the diseased animals cannot be identified separately from healthy wildlife prior to the kill, we find that harvest-based strategies alone have no impact on disease transmission. Other controls that directly influence disease transmission and/or mortality are required. Next, we analyze the socially optimal management of infectious wildlife. The model is applied to the problem of bovine tuberculosis among Michigan white-tailed deer, with non-selective harvests and supplemental feeding being the control variables. Using …

Ascaris Suum: Cdna Microarray Analysis Of 4th Stage Larvae (L4) During Self-Cure From The Intestine, Motoko Morimoto, Dante Zarlenga, Hunter Beard, Nadim Alkharouf, Benjamin F. Matthews, Joseph F. Urban Jr.

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

There is spontaneous cure of a large portion of Ascaris suum 4th-stage larvae (L4) from the jejunum of infected pigs between 14 and 21 days after inoculation (DAI). Those L4 that remain in the jejunum continue to develop while those that have moved to the ileum are eventually expelled from the intestines. Although increases in intestinal mucosal mast cells and changes in localhost immunity are coincidental with spontaneous cure, the population of L4 that continue to develop in the jejunum may counteract host protective mechanisms by the differential production of factors related to parasitism. To this end, a cDNA library …

Anxiety, Stress, And Health In Northern Plains Native Americans, Tami J. De Coteau, Debra A. Hope, Jessiline Anderson

Department of Psychology: Faculty Publications

In the present study, the Beck Anxiety Inventory (Beck, Epstein, Brown, & Steer, 1988), Anxiety Sensitivity Inventory (Peterson & Reiss, 1992), the Holmes-Rahe Social Readjustment Rating Scale (Holmes & Rahe, 1967), Northern Plains Bicultural Inventory (Allen & French, 1994), and a health questionnaire were administered to investigate the relationship between anxiety, stressful events, health, and cultural participation among 147 Native American adults from a Midwestern reservation community. The results of these self-report measures indicated that, as has been found in the majority culture, stressful life events predicted physical health problems and self-reported anxiety. The hypothesis that participation in and identification …

To The Editor: Reply To Sarmati, Brad P. Brayfield, John T. West, Charles D. Mitchell, Charles Wood

Nebraska Center for Virology: Faculty Publications

The letter by Sarmati et al. [1] presents data indicating that they were unable to find a significant correlation between human herpesvirus (HHV)–8 seropositivity and a history of spontaneous abortion in a group of 245 human immunodeficiency virus (HIV) type 1–seronegative women but that they did observe a correlation between high HHV-8 antibody titers (≥1:1280) and spontaneous abortion. Although it is possible that an increased risk of spontaneous abortion may be associated with active infection with HHV-8, at this point there is not enough evidence to support such an association. Given that several human herpes viruses are well-known agents of …

Review Of Molecular Infection Biology: Interactions Between Mircoorganisms And Cells By Jörg Hacker And Jürgen Heesemann, Jeffrey D. Cirillo

School of Veterinary and Biomedical Sciences: Faculty Publications

Pathogenesis is one potential outcome of the constant struggle between host defenses and the desire of microorganisms to acquire a privileged niche. This mutually competitive evolutionary process has resulted in interactions among complex and often elegant systems throughout the course of infections. The complexity of these interactions and the large number of infectious agents that exist makes the introduction of students to infectious diseases, as well as a comprehensive review of the field, an extremely daunting task. This book provides just such a comprehensive and timely description of the field in a manner that is easily understandable and enjoyable to …

Association Of Borrelia Garinii And B. Valaisiana With Songbirds In Slovakia, Klara Hanincova, Veronika Taragelova, Juraj Koci, Stefanie M. Schafer, Rosie Hails, Amy J. Ullmann, Joseph Piesman, Milan Labuda, Klaus Kurtenbach

United States Public Health Resources

In Europe, 6 of the 11 genospecies of Borrelia burgdorferi sensu lato are prevalent in questing Ixodes ricinus ticks. In most parts of Central Europe, B. afzelii, B. garinii, and B. valaisiana are the most frequent species, whereas B. burgdorferi sensu stricto, B. bissettii, and B. lusitaniae are rare. Previously, it has been shown that B. afzelii is associated with European rodents. Therefore, the aim of this study was to identify reservoir hosts of B. garinii and B. valaisiana in Slovakia. Songbirds were captured in a woodland near Bratislava and investigated for engorged ticks. Questing I. ricinus ticks …

Phyllodistomum Funduli N. Sp. (Trematoda: Gorgoderidae) From Fundulus Sciadicus Cope From Cedar Creek In Western Nebraska, Jaclyn Helt, John J. Janvoy Jr., John Ubelaker

John J. Janovy, Jr. Publications

Phyllodistomum funduli n. sp. is described from the urinary bladder and ureters of the Plains topminnow, Fundulus sciadicus, from Cedar Creek in Keith County, Nebraska (41°11.18'N, 101°21.77'W). Phyllodistomum funduli differs from most other Phyllodistomum species reported in possessing an oral sucker that is larger than the acetabulum. Currently, 7 other species of Phyllodistomum have been reported to possess this trait. A comparison of P. funduli with these 7 other species indicates that P. funduli is a distinct species, lacking notches, posterior body folds, caudal projections, or cephalic glands found in some congeners. There is no published report on parasites …

Survey For Coccidia And Haemosporidia In The Lesser Prairie Chicken (Typanuchus Pallidicinctus) From New Mexico With The Description Of A New Eimeria Species, B. H. Smith, Donald Duszynski, K. Johnson

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Blood films and fecal samples of the lesser prairie-chicken (Tympanuchus pallidicinctus) were examined for parasites when we surveyed specimens captured during a radio-tracking study conducted in Chaves County, New Mexico (USA). All birds were captured on the Caprock Wildlife Habitat Management Area, administered by the Bureau of Land Management. Samples were collected in late March, April, and early May 1998-2000. Oocysts were detected in five of 64 (8%) birds sampled and, upon sporulation, were determined to be an Eimeria species. This is the first eimerian reported from the lesser prairie-chicken and is described here as a new species. …
