Bovine Tuberculosis In Swedish Farmed Deer: Detection And Control Of The Disease, Helene Wahlström

Michigan Bovine Tuberculosis Bibliography and Database

Bovine tuberculosis (BTB) was introduced into Swedish farmed deer herds in 1987. Epidemiological investigations showed that 10 deer herds had become infected (July 1994) and a common source of infection, a consignment of 168 imported farmed fallow deer, was identified (I).

As trace-back of all imported and in-contact deer was not possible, a control program, based on tuberculin testing, was implemented in July 1994. As Sweden has been free from BTB since 1958, few practicing veterinarians had experience in tuberculin testing. In this test, result relies on the skill, experience and conscientiousness of the testing veterinarian. Deficiencies in performing the …

Wif-B Cells As A Model For Alcohol-Induced Hepatocyte Injury, Courtney S. Schaffert, Sandra L. Todero, Benita L. Mcvicker, Pamela L. Tuma, Michael F. Sorrell, Dean J. Tuma

United States Public Health Resources

A potential in vitro model for studying the mechanisms of alcohol-induced hepatocyte injury is the WIF-B cell line. It has many hepatocyte-like features, including a differentiated, polarized phenotype resulting in formation of bile canaliculi. The aim of this study was to examine the effects of ethanol treatment on this cell line. WIF-B cells were cultured up to 96 h in the absence or presence of 25 mM ethanol and subsequently were analyzed for ethanol-induced physiological and morphological changes. Initial studies revealed WIF-B cells exhibited alcohol dehydrogenase (ADH) activity, expressed cytochrome P4502E1 (CYP2E1), and efficiently metabolized ethanol in culture. This cell …

Natural And Technologic Hazardous Material Releases During And After Natural Disasters: A Review, Stacy Young, Lina Balluz, Josephine Malilay

United States Public Health Resources

Natural disasters may be powerful and prominent mechanisms of direct and indirect hazardous material (hazmat) releases. Hazardous materials that are released as the result of a technologic malfunction precipitated by a natural event are referred to as natural-technologic or na-tech events. Na-tech events pose unique environmental and human hazards. Disaster-associated hazardous material releases are of concern, given increases in population density and accelerating industrial development in areas subject to natural disasters. These trends increase the probability of catastrophic future disasters and the potential for mass human exposure to hazardous materials released during disasters. This systematic review summarizes direct and indirect …

Real-Time Fluorescence Pcr Assays For Detection And Characterization Of Heat-Labile I And Heat-Stable I Enterotoxin Genes From Enterotoxigenic Escherichia Coli, Udo Reischl, Mohammad T. Youssef, Hans Wolf, Eija Hyytia-Trees, Nancy A. Strockbine

United States Public Health Resources

To facilitate the diagnosis of enterotoxigenic Escherichia coli (ETEC) infections in humans, we developed and evaluated real-time fluorescence PCR assays for the Roche LightCycler (LC) against the enterotoxin genes commonly present in strains associated with human illness. Separate LC-PCR assays with identical cycling conditions were designed for the type I heat-labile enterotoxin (LT I) and the type I heat-stable enterotoxin (ST I) genes, using the LC hybridization probe format. A duplex assay for ST I with two sets of amplification primers and three hybridization probes was required to detect the major nucleotide sequence variants of ST I, ST Ia and …

West Nile Virus Blood Transfusion-Related Infection Despite Nucleic Acid Testing, Alexandre Macedo De Oliveira, Brady D. Beecham, Susan P. Montgomery, Robert S. Lanciotti, Jeffrey M. Linnen, Cristina Giachetti, Larry A. Pietrelli, Susan L. Stramer, Thomas J. Safranek

United States Public Health Resources

BACKGROUND: A case of West Nile virus (WNV) encephalitis associated with transfusion of blood that did not react when tested for WNV by minipool (MP) nucleic acid testing (NAT) is described. A Nebraska man developed clinical encephalitis 13 days after surgery and transfusion of 26 blood components. Antibody testing confirmed WNV infection. An investigation was initiated to determine the source of this infection.

STUDY DESIGN AND METHODS: The patient’s family members were interviewed to identify risk factors for WNV infection. Residual samples were retested for WNV RNA using transcription-mediated amplification (TMA) assay and two polymerase chain reaction (PCR) assays. …

Farm Fatalities To Youth 1995–2000: A Comparison By Age Groups, Michael Goldcamp, Kitty J. Hendricks, John R. Myers

United States Public Health Resources

Problem: Although a myriad of research illustrates the safety issues related to farm fatalities in youth populations, very little empirical evidence exists that includes work and non-work related farm fatalities to all youths under 20 years of age at the national level.
Methods: This research will use death certificate data for the six years from 1995 to 2000 that were collected by NIOSH from all 50 state vital statistics registries. Demographic data from the 1998 CAIS were used in rate calculations. In addition to providing annual fatality rates and descriptions of the general causes of death, this research will examine …

Agricultural Pesticide Use And Adenocarcinomas Of The Stomach And Oesophagus, W. J. Lee, W. Lijinsky, E. F. Heineman, R. S. Markin, D. D. Weisenburger, M. H. Ward

United States Public Health Resources

Aims: To evaluate the risk of the stomach and oesophageal adenocarcinomas associated with farming and agricultural pesticide use.
Methods: Population based case-control study in eastern Nebraska. Telephone interviews were conducted with men and women diagnosed with adenocarcinoma of the stomach (n = 170) or oesophagus (n = 137) between 1988 and 1993, and controls (n = 502) randomly selected from the same geographical area. Unconditional logistic regression was used to calculate adjusted odds ratios (ORs) for farming and for use of individual and chemical classes of insecticides and herbicides, including pesticides classified as nitrosatable (able to form N-nitroso compounds on …

Neurobehavioral Evaluation For A Community With Chronic Exposure To Hydrogen Sulfide Gas, Steven G. Inserra, Betty L. Phifer, W. Kent Anger, Michael Lewin, Roberta Hilsdon, Mary C. White

United States Public Health Resources

In May 2000, the Agency for Toxic Substances and Disease Registry of the US government conducted a health investigation in response to community concerns regarding ambient and indoor hydrogen sulfide (H₂S), odor, and health symptoms in Dakota City, Nebraska. The objective was to determine whether adult residents in an area with repeated exposure to H₂S showed poorer performance on neurobehavioral tests than unexposed residents. Study participants were required to meet age (≥16 years of age) and length of residency (2 years) eligibility requirements. A battery of computer-assisted standardized neurobehavioral tests was administered in English or Spanish. …

Outbreak Of Pruritic Rashes Associated With Mites — Kansas, 2004

United States Public Health Resources

In late August 2004, the Kansas Department of Health and Environment (KDHE) received reports from the Crawford County Health Department (CCHD) of approximately 300 residents of Pittsburg, Kansas (2000 population: 19,243), seeking care for a pruritic rash of unknown etiology. In early September, three neighboring counties in Kansas and two neighboring states (Missouri and Nebraska) also reported such cases. These events prompted KDHE to request assistance from CDC. Additional cases subsequently were reported in Oklahoma and Texas. This report describes the investigation in Crawford County, Kansas, by public health agencies and entomologists to identify the etiology of the pruritic rash …

Alcohol And Hiv Decrease Proteasome And Immunoproteasome Function In Macrophages: Implications For Impaired Immune Function During Disease, James Haorah, David Heilman, Casey Diekmann, Natalia Osna, Terrence M. Donohue Jr., Anuja Ghorpade, Yuri Persidsky

United States Public Health Resources

Proteasomes (proteinase complexes, PR) and immunoproteasomes (IPR) degrade damaged proteins and affect protein processing required for antigen presentation by mononuclear phagocytes. These critical immune processes are attenuated during progressive HIV-1 infection and are affected by alcohol abuse. To investigate the mechanisms underlying these functional changes, we measured PR and CYP2E1 activities [an ethanol (EtOH) metabolizing enzyme] and reactive oxygen species (ROS) in human monocyte-derived macrophages (MDM) following HIV-1 infection and EtOH treatment. We observed progressive declines of PR activity and PR/IPR contents in HIV-1-infected MDM. PR activity and IPR expression increased after IFN-γ stimulation but reduced after HIV-1 infection. EtOH …

Molecular Characterization Of Noroviruses Detected In Diarrheic Stools Of Michigan And Wisconsin Dairy Calves: Circulation Of Two Distinct Subgroups, Annabel G. Wise, Stephan S. Monroe, Lora E. Hanson, Daniel L. Grooms, Donald Sockett, Roger K. Maes

United States Public Health Resources

Noroviruses have emerged as the leading worldwide cause of acute non-bacterial gastroenteritis in humans. The presence of noroviruses in diarrheic stool samples from calves on Michigan and Wisconsin dairy farms was investigated by RT-PCR. Norovirus-positive samples were found on all eight farms studied in Michigan and on 2 out of 14 farms in Wisconsin. Phylogenetic analyses of partial polymerase and capsid sequences, derived for a subset of these bovine noroviruses, showed that these strains formed a group which is genetically distinct from the human noroviruses, but more closely related to genogroup I than to genogroup II human noroviruses. Examination of …

Transcriptional Regulation Of The Murine Elf3 Gene In Embryonal Carcinoma Cells And Their Differentiated Counterparts: Requirement For A Novel Upstream Regulatory Region, Jingwen Hou, Phillip J. Wilder, Cory T. Bernadt, Brian Boer, Richard M. Neve, Angie Rizzino

United States Public Health Resources

The transcription factor Elf3, which is one of over 25 Ets family members, is expressed in a wide variety of carcinomas and has been shown to promote the transcription of many genes implicated in cancer. To understand how the Elf3 gene is regulated at the transcriptional level, we probed its 5’-flanking region, and we report here the identification of both proximal and distal regions that regulate murine Elf3 promoter activity. In addition to mapping the transcription start site of the Elf3 gene, the work described in this study identifies four cisregulatory elements in the proximal promoter region of the gene. …

N-(Methylamino) Isobutyric Acid Inhibits Proliferation Of Cfsc-2c Hepatic Stellate Cells, T. L. Freeman, G.M. Thiele, L.W. Klassen, B.T. Klassen, M.E. Mailliard

United States Public Health Resources

Activation of hepatic stellate cells (HSCs) involves the induction of ECM protein synthesis and rapid cell proliferation. Thus, agents that interfere with either process could potentially mitigate the development of liver disease by reducing the synthesis of proteins associated with fibrosis or by reducing the number of activated HSC. Previously, we described that the non-metabolizable amino acid analog N-(methylamino)isobutyric acid (MeAIB) reduced hepatic collagen content of rats in a model of CCl₄-induced liver injury, and in vitro studies using CFSC-2G cells indicated that MeAIB directly reduced collagen synthesis. However, the MeAIB-mediated reduction of hepatic collagen, in vivo, …

Risk Of Disease From Wildlife Reservoirs: Badgers, Cattle, And Bovine Tuberculosis, M. Scantlebury, M. R. Hutchings, D. J. Allcroft, S. Harris

Michigan Bovine Tuberculosis Bibliography and Database

Livestock face complex foraging options associated with optimizing nutrient intake while being able to avoid areas posing risk of parasites or disease. Areas of tall nutrient-rich swards around fecal deposits may be attractive for grazing, but might incur fitness costs from parasites. We use the example of dairy cattle and the risks of tuberculosis transmission posed to them by pastures contaminated with badger excreta to examine this trade-off. A risk may be posed either by aerosolized inhalation through investigation or by ingestion via grazing contaminated swards. We quantified the levels of investigation and grazing of 150 dairy cows at badger …

Use Of Erythropoietin In Cancer Patients: Assessment Of Oncologists’ Practice Patterns In The United States And Other Countries, Jared R. Adams, Linda S. Elting, Gary H. Lyman, James N. George, Barry C. Lembersky, James O. Armitage, George D. Demetri, Charles L. Bennett

United States Public Health Resources

PURPOSE: To assess physician use of erythropoietin in cancer patients before publication of the American Society of Clinical Oncology/American Society of Hematology guidelines.
METHODS: Questionnaires about erythropoietin use in practice and 12 hypothetical clinical scenarios involving patients with cancer were mailed to 2000 oncologists/hematologists in the United States and 19 other countries. Response rates were 30% in the United States and 25% internationally. Data on erythropoietin use for ovarian cancer were obtained from one clinical trial. Multivariate regression models assessed predictors of erythropoietin prescription.
RESULTS: Most physicians selected a hemoglobin level ≤10 g/dL as an upper threshold for erythropoietin use …

Cognitive Constraints On Reciprocity And Tolerated Scrounging, Jeffrey R. Stevens, Fiery A. Cushman

Department of Psychology: Faculty Publications

Commentary on Gurven: "To give and to give not: The behavioral ecology of human food transfers"

Each of the food-sharing models that Gurven considers demands unique cognitive capacities. Reciprocal altruism, in particular, requires a suite of complex abilities not required by alternatives such as tolerated scrounging. Integrating cognitive constraints with comparative data from other species can illuminate the adaptive benefits of food sharing in humans.

Phosphorylation Of Vesicular Stomatitis Virus Phosphoprotein P Is Indispensable For Virus Growth†, Subash C. Das, Asit K. Pattnaik

School of Veterinary and Biomedical Sciences: Faculty Publications

The phosphoprotein (P) of vesicular stomatitis virus (VSV) is an essential subunit of the viral RNAdependent RNA polymerase (RdRp) complex. It is phosphorylated at two different domains. Using defective interfering (DI) RNA or minigenomic RNA templates, we previously demonstrated that phosphorylation within the amino-terminal domain I is essential for transcription, whereas phosphorylation within the carboxyterminal domain II is necessary for replication. For the present study, we examined the role of the phosphorylation of residues in these domains in the life cycle of VSV. Various mutant P coding sequences were inserted into a full-length cDNA clone of VSV, and the virus …

Glycosyltransferases Encoded By Viruses, Nicolas Markine-Goriaynoff, Laurent Gillet, James L. Van Etten, Haralambos Korres, Naresh Verma, Alain Vanderplasschen

James Van Etten Publications

Studies of cellular biology in recent decades have highlighted the crucial roles of glycans in numerous important biological processes, raising the concept of glycomics that is now considered as important as genomics, transcriptomics and proteomics. For millions of years, viruses have been co-evolving with their hosts. Consequently, during this co-evolution process, viruses have acquired mechanisms to mimic, hijack or sabotage host processes that favour their replication, including mechanisms to modify the glycome. The importance of the glycome in the regulation of host–virus interactions has recently led to a new concept called ‘glycovirology’. One fascinating aspect of glycovirology is the study …

Patterns Of Variations In Escherichia Coli Strains That Produce Cytolethal Distending Toxin, Carol L. Pickett, Robert B. Lee, Aysegul Eyigor, Ben Elitzur, Emily M. Fox, Nancy A. Strockbine

United States Public Health Resources

A collection of 20 Escherichia coli strains that produce cytolethal distending toxin (CDT) were analyzed for their virulence-associated genes. All of these strains were serotyped, and multiplex PCR analysis was used to ascertain the presence of genes encoding other virulence factors, including Shiga toxin, intimin, enterohemolysin, cytotoxic necrotizing factor type 1 (CNF1) and CNF2, heat-stable toxin, and heat-labile toxin. These CDT-producing strains possessed various combinations of known virulence genes, some of which have not been noted before. Partial cdtB sequences were obtained from 10 of these strains, and their predicted CdtB sequences were compared to known E. coli CdtB sequences; …

Michigan Bovine Tuberculosis Bibliography and Database

Mycobacterium bovis infection in wildlife and feral species is a potential source of infection for livestock and a threat to protected and endangered species. The aim of this study was to identify Spanish wild animal species infected with M. bovis through bacteriological culture and spacer oligonucleotide typing (spoligotyping) of isolates for epidemiological purposes. This study included samples from red deer (Cervus elaphus), fallow deer (Dama dama), wild boar (Sus scrofa), Iberian lynx (Lynx pardina), hare (Lepus europaeus), and cattle (Bos taurus). They were collected in several geographical areas …

Shared Feed As A Means Of Deer-To-Deer Transmission Of Mycobacterium Bovis, Mitchell V. Palmer, W. Ray Waters, Diana L. Whipple

Michigan Bovine Tuberculosis Bibliography and Database

To determine the ability of experimentally inoculated white-tailed deer (Odocoileus virginianus) to transmit Mycobacterium bovis to naive deer through the sharing of feed, four deer were intratonsillarly inoculated with 4x10⁵ colony-forming units of M. bovis. On a daily basis, feed not consumed by inoculated deer after approximately 8 hr was offered to four naıve deer maintained in a separate pen, where direct contact, aerosol transmission, or transmission through personnel were prevented. After 150 days, naıve deer were euthanized and examined. All naıve deer had lesions consistent with tuberculosis and M. bovis was isolated from various tissues. …

Evaluation Of An In Vitro Blood-Based Assay To Detect Production Of Interferon-Γ By Mycobacterium Bovis–Infected White-Tailed Deer (Odocoileus Virginianus), Mitchell V. Palmer, W. Ray Waters, Diana L. Whipple, Ralph E. Slaughter, Stephen L. Jones

Michigan Bovine Tuberculosis Bibliography and Database

Tuberculosis due to Mycobacterium bovis in captive Cervidae was identified as an important disease in the United States in 1990 and prompted the addition of captive Cervidae to the USDA Uniform Methods and Rules for eradication of bovine tuberculosis. As well, M. bovis infection was identified in free-ranging white-tailed deer in northeast Michigan in 1995. Tuberculosis in both captive and free-ranging Cervidae represents a serious challenge to the eradication of M. bovis infection from the United States. Currently, the only approved antemortem tests for tuberculosis in Cervidae are the intradermal tuberculin skin test and the blood tuberculosis test (BTB). At …

Copolymer 1 [Cop1, glatiramer acetate, Copaxone, poly(Y,E,A,K)n] is widely used in the treatment of relapsing/remitting multiple sclerosis in which it reduces the frequency of relapses by ≈30%. In the present study, copolymers with modified amino acid compositions (based on the binding motif of myelin basic protein 85–99 to HLA-DR2) have been developed with the aim of suppressing multiple sclerosis more effectively. The enhanced efficacy of these copolymers in experimental autoimmune encephalomyelitis (EAE) induced in SJL/J mice with proteolipid protein 139–151 was demonstrated by using three protocols: (i) simultaneous administration of autoantigen and copolymer (termed prevention), (ii) …

The Mind In The Mind Of The Beholder: Elucidating Relational Influences On Early Social Understanding, Ross Thompson, H. Abigail Raikes

Department of Psychology: Faculty Publications

Relational experiences shape emergent social understanding and two influences deserve particular attention. First, parent-child conversation about shared experiences incorporates both implicit and explicit information about mental states that catalyzes the social construction of understanding, especially in juxtaposition with the child’s direct experience. Second, emotion infuses the contexts and cognitions about social experiences that provoke the child’s constructivist efforts.

Motivation, Drug Abuse, And 50 Years Of Theoretical And Empirical Inquiry, Rick A. Bevins, Michael Bardo

Department of Psychology: Faculty Publications

In reviewing the 25-year history of the Nebraska Symposium on Motivation, Benjamin and Jones (1979) noted that the Symposium was "the longest-lived topical series in American psychology, with 'I national and international reputation" (p. ix). On March 28 and 29 of 2002, with a packed auditorium on the campus of the University of Nebraska-Lincoln, this record was doubled in life. As the reader will quickly see from the list of contributors, the reputation of the Symposium was also maintained on its 50th Anniversary. Before continuing, we would like to reiterate the thanks in the Preface for all those who supported …

Histamine As An Aid To Biopsy Of Third Eyelid Lymphoid Tissue In Sheep, S. Bender, J. Alverson, L. M. Herrmann, Katherine I. O'Rourke

Zoonotics and Wildlife Disease: Publications

TRANSMISSIBLE spongiform encephalopathies, of which ovine scrapie is a prototype, are neurodegenerative disorders characterised by the accumulation of an abnormal isoform (PrP-scrapie or PrP^Sc) of a normal cellular protein (PrP^C) (Prusiner 1982). Characteristics of the disease include long incubation periods, and a progressive and chronic clinical course resulting in death (Fraser 1976). PrP^sc is detectable during the preclinical stages of scrapie in peripheral lymph nodes (Ikegami and others 1991, Muramatsu and others 1993), in lymphoid follicles of the tonsils (Schreuder and others 1996) and in lymphoid follicles of the nictitating membrane or third eyelid (O'Rourke …

Cd46-Mediated Transduction Of A Species D Adenovirus Vaccine Improves Mucosal Vaccine Efficacy, Zenaido T. Camacho, Mallory A. Turner, Michael A. Barry, Eric A. Weaver

Nebraska Center for Virology: Faculty Publications

The high levels of preexisting immunity against Adenovirus type 5 (Ad5) have deemed Ad5 unusable for translation as a human vaccine vector. Low seroprevalent alternative viral vectors may be less impacted by preexisting immunity, but they may also have significantly different phenotypes from that of Ad5. In this study we compare species D Ads (26, 28, and 48) to the species C Ad5. In vitro transduction studies show striking differences between the species C and D viruses. Most notably, Ad26 transduced human dendritic cells much more effectively than Ad5. In vivo imaging studies showed strikingly different transgene expression profiles. The …

Phylogenetic Analyses Of Texas Isolates Indicate An Evolving Subtype Of The Clade B Feline Immunodeficiency Viruses, Eric A. Weaver, Ellen W. Collisson, Margaret Slater, Guan Zhu

Nebraska Center for Virology: Faculty Publications

Rigorous phylogenetic analyses were used to compare the nucleotide sequences of feline immunodeficiency virus strains isolated from Texas and throughout the world. The envelope V3-V4 sequences and capsid gene of the Texas isolates formed a cluster between subtypes B and E. Statistical comparisons with other published sequences confirmed that the Texas group is a unique cluster, possibly a new subtype, arising from subtype B.
