Influence Of An Internal Parasite Control On Cattle Grazing Behavior And Production, Jace Stott
Influence Of An Internal Parasite Control On Cattle Grazing Behavior And Production, Jace Stott
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Six herds of 45 to 90 cow/calf pairs grazing on upland range were used to examine the efficacy of an injectable extended release eprinomectin parasite control on production traits, activity behavior, and efficacy against internal parasitism. In 2016, treatment cows were given a subcutaneous injection of LongRangetm. In 2017, all cows in the study were treated with a short acting Synanthictm treatment and only treatment cows were given an additional LongRangetm treatment. In both 2016 and 2017, fecal egg counts were significantly lower (P < 0.05) in eprinomectin treated cows compared to control cows. Calf gains were 4.8 kg and 8.7 kg greater (P < 0.1) for the calves of dams treated with eprinomectin compared to calves of control cows in 2016 and 2017, respectively. Activity characteristics of cattle were inconclusive, with treated cows having lower (P < 0.01) grazing and traveling times compared to control cows in 2016, and more (P < 0.01) grazing and traveling in 2017.
Differences in grazing behaviors based on time within pasture at different times …

Responding To Infertility: Lessons From A Growing Body Of Research And Suggested Guidelines For Practice, Karina M. Shreffler, Arthur L. Greil, Julia Mcquillan
Department of Sociology: Faculty Publications
Infertility is a common, yet often misunderstood, experience. Infertility is an important topic for family scientists because of its effects on families; its relevance to research in related areas, such as fertility trends and reproductive health; and its implications for practitioners who work with individuals and couples experiencing infertility. In this review, we focus on common misperceptions in knowledge and treatment of infertility and highlight insights from recent research that includes men, couples, and people with infertility who are not in treatment. The meaning of parenthood, childlessness, awareness of a fertility problem, and access to resources are particularly relevant for …
Cross-Reactive Immunity To Porcine Reproductive And Respiratory Syndrome Virus And Its Contribution To Protection, Ignacio Correas
Cross-Reactive Immunity To Porcine Reproductive And Respiratory Syndrome Virus And Its Contribution To Protection, Ignacio Correas
School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research
Due to the vast geographical distribution and significant economic losses generated, porcine reproductive and respiratory syndrome virus (PRRSV) can be considered the most important swine pathogen of contemporary times. Current control and eradication strategies against PRRSV have difficulty succeeding because of their complex nature and the absence of an effective vaccine. A major obstacle for PRRSV vaccine development is the broad heterogeneity of the virus, both at the genetic and antigenic level, its rapid evolution, and an incomplete knowledge of the immune responses responsible for clearing the virus from the host. Specifically, how known correlates of protection against PRRSV—neutralizing antibodies …
Induction And Suppression Of Antiviral Rna Silencing By Tomato Spotted Wilt Virus, Sergio M. Gabriel Peralta
Induction And Suppression Of Antiviral Rna Silencing By Tomato Spotted Wilt Virus, Sergio M. Gabriel Peralta
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Tomato spotted wilt virus (TSWV) is an emerging pathogen with wide host range and one of the most important viruses of plants. Information regarding processing of negative single stranded RNA viruses such as TSWV in the RNA silencing pathway remains limited. In nature TSWV is only transmitted by thrips as vectors and since infection occurs in both thrips and plants, an experimental system to transmit using thrips and the detection of TSWV were established. In order to understand the processing of TSWV in the RNA silencing pathway, Arabidopsis thaliana as a model plant was used in the genetic analysis against …
Honey Bee Gut Dysbiosis: A Novel Context Of Disease Ecology, Kirk E. Anderson, Vincent A. Ricigliano
Honey Bee Gut Dysbiosis: A Novel Context Of Disease Ecology, Kirk E. Anderson, Vincent A. Ricigliano
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
The honey bee microbiota has become a hot-spot of recent research. Highly co-evolved with its host, the hindgut microbiota of a worker honey bee consists of six bacterial species shown to occur reliably in particular proportions. Altered microbiota structure is associated with host deficiencies, and a variety of bacteria found throughout the hive environment can dominate the worker gut suppressing or displacing microbiota function. The synthesis presented here suggests environmental insults alter gut bacterial balance, leading to decreased host function and disease progression. Specific functional groups of native bacteria represent a model system to investigate dysbiosis and the evolution of …

Small bowel transplantation (SBT) can be a life-saving medical procedure. However, these recipients experience high risk of bloodstream infections caused by Candida. This research aims to characterize the SBT recipient gut microbiota over time following transplantation and investigate the epidemiology of candidemia in seven pediatric patients. Candida species from the recipients’ ileum and bloodstream were identified by internal transcribed spacer sequence and distinguished to strain by multilocus sequence typing and randomly amplified polymorphic DNA. Antifungal susceptibility of bloodstream isolates was determined against nine antifungals. Twenty-two ileostomy samples harbored at least one Candida species. Fungemia were caused by Candida parapsilosis …

Background: Eliciting doses (EDs) of allergenic foods can be defined by the distribution of threshold doses for subjects within a specific population. The ED05 is the dose that elicits a reaction in 5% of allergic subjects. The predicted ED05 for peanut is 1.5 mg of peanut protein (6 mg of whole peanut).
Objective: We sought to validate the predicted peanut ED05 (1.5 mg) with a novel single-dose challenge.
Methods: Consecutive eligible children with peanut allergy in 3 centers were prospectively invited to participate, irrespective of previous reaction severity. Predetermined criteria for objective reactions were used …
Regulation Of Alpha-Herpesvirus Reactivation From Latency By Stress, Insun Kook
Regulation Of Alpha-Herpesvirus Reactivation From Latency By Stress, Insun Kook
School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research
Bovine herpes virus 1 (BHV-1) and Herpes simplex virus 1 (HSV-1) are crucial etiological viral agent of clinical diseases. HSV-1 and BHV-1 establish latent infection in sensory neurons. Periodically, reactivation from latency occurs resulting in virus excretion and transmission. Stress increases corticosteroid levels and the incidence of HSV-1 and BHV-1 reactivation from latency. The synthetic corticosteroid, dexamethasone (DEX) mimics stress and induces BHV-1 and HSV-1 reactivation. However, molecular mechanisms by which corticosteroid mediates viral reactivation are not well understood. My dissertation has focused on elucidating events that induce BHV- 1 or HSV-1 reactivation during the early stages of stress-induced escape …
Loss Of Exogenous Androgen Dependence By Prostate Tumor Cells Is Associated With Elevated Glucuronidation Potential, Brenna M. Zimmer, Michelle E. Howell, Qin Wei, Linlin Ma, Trevor Romsdahl, Eileen G. Loughman, Jennifer E. Markham, Javier Seravalli, Joseph J. Barycki, Melanie A. Simpson
Loss Of Exogenous Androgen Dependence By Prostate Tumor Cells Is Associated With Elevated Glucuronidation Potential, Brenna M. Zimmer, Michelle E. Howell, Qin Wei, Linlin Ma, Trevor Romsdahl, Eileen G. Loughman, Jennifer E. Markham, Javier Seravalli, Joseph J. Barycki, Melanie A. Simpson
Department of Biochemistry: Faculty Publications
Prostate epithelial cells control the potency and availability of androgen hormones in part by inactivation and elimination. UDP-glucose dehydrogenase (UGDH) catalyzes the NAD+-dependent oxidation of UDP-glucose to UDP-glucuronate, an essential precursor for androgen inactivation by the prostate glucuronidation enzymes UGT2B15 and UGT2B17. UGDH expression is androgen stimulated, which increases the production of UDP-glucuronate, and fuels UGT-catalyzed glucuronidation. In this study, we compared the glucuronidation potential and its impact on androgen-mediated gene expression in an isogenic LNCaP model for androgen dependent versus castration resistant prostate cancer. Despite significantly lower androgen-glucuronide output, LNCaP 81 castration resistant tumor cells expressed higher …

Current research in virology is changing public conceptions about vaccines and infectious disease. The University of Nebraska State Museum collaborated with research virologists, science writers, artists and learning researchers to create public outreach materials about viruses and infectious disease. The project, funded by the National Institute of Health’s SEPA program, developed comics, a book with Carl Zimmer, and other materials and programs. The project launched three kinds of learning research: 1) a survey of Nebraska adults on their opinions about vaccines and infectious disease; 2) a study comparing the mental models of viruses, vaccines and infection from virologists, teachers, and …
Stabilization Of Gp120 Outer Domain For Hiv-1-1 Vaccine Immunogen Design, Duoyi Hu
Stabilization Of Gp120 Outer Domain For Hiv-1-1 Vaccine Immunogen Design, Duoyi Hu
School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research
The sole envelope glycoprotein spike on the surface of Human Immunodeficiency Virus (HIV-1) is composed of two subunits: gp120 and gp41. The gp120 consists of three domains: the inner domain, outer domain and bridging sheet, to which the viral primary receptor CD4 binds and induces a conformational change in gp120 to expose the co-receptor binding site. Previous studies have found that the outer domain of gp120 is relatively more stable than the inner domain and bridging sheet. When superimposed, the co-crystal structures of CD4-gp120 complex and VRC01-gp120 complex revealed that the CD4-binding site (CD4-BS) antibody VRC01 actually mainly bound to …
Diffusion Modeling And Device Development For Peritoneal Membrane Oxygenation, Liana Hatoum
Diffusion Modeling And Device Development For Peritoneal Membrane Oxygenation, Liana Hatoum
Department of Mechanical and Materials Engineering: Dissertations, Theses, and Student Research
Acute respiratory distress syndrome (ARDS) is a pulmonary disease that causes hypoxemia and respiratory failure. The mortality rate for ARDS ranges between 27% and 45%. Current treatments including mechanical ventilation and extracorporeal membrane oxygenation (ECMO) are often associated with high risk complications including barotrauma, infection, thrombosis, and hemorrhage. Alternative pulmonary support techniques are needed to improve the survival rate of patients suffering from ARDS. Previous studies introducing pure O2 gas, perfluorocarbons and red blood cells into the intraperitoneal (IP) cavity have reported no effect or only a mild increase in oxygenation. Here we report peritoneal membrane oxygenation (PMO) using …

Examining Maternal Obesity Effects On Oogenesis, Follicular Development, And Embryonic Myogenesis, Chris Lindeman, Jennifer Wood
UCARE: Research Products
The CDC estimates that more than one-third of U.S. adults (approximately 78.6 million) are obese. Despite national efforts to combat this with diet and exercise, the number of obese adults and children continues to climb. It is critical to emphasize that obesity can lead to lifelong, chronic complications and health risks including hypertension, heart disease, and diabetes.
Diet and obesity also have important impacts on the reproductive health of female including the ability to become pregnant (fertility) and risk for complications during pregnancy. Furthermore, for women who do become pregnant, obesity can affect the development of the embryo and fetus, …

Echinococcus Multilocularis In Foxes And Raccoon Dogs: An Increasing Concern For Baltic Countries, Guna Bagrade, Gunita Deksne, Zanda Ozoliņa, Samantha Jane Howlett, Maria Interisano, Adriano Casulli, Edoardo Pozio
Harold W. Manter Laboratory of Parasitology: Library Materials
Background
In Europe, the life cycle of Echinococcus multilocularis is predominantly sylvatic, involving red foxes (Vulpes vulpes) as the main definitive hosts and rodents such as muskrats and arvicolids as intermediate hosts. The parasite is the etiological agent of human alveolar echinococcosis, a malignant zoonotic disease caused by the accidental ingestion of eggs shed by definitive hosts in their feces. The aims of this study were to investigate the prevalence of E. multilocularis in red foxes and raccoon dogs (Nyctereutes procyonoides) and to study the environmental factors favoring the perpetuation of the parasite in Latvia. …

Rnai-Mediated Control Of Aflatoxins In Peanut: Method To Analyze Mycotoxin Production And Transgene Expression In The Peanut/Aspergillus Pathosystem, Renee S. Arias, Phat M. Dang, Victor S. Sobolev
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
The Food and Agriculture Organization of the United Nations estimates that 25% of the food crops in the world are contaminated with aflatoxins. That represents 100 million tons of food being destroyed or diverted to non-human consumption each year. Aflatoxins are powerful carcinogens normally accumulated by the fungi Aspergillus flavus and A. parasiticus in cereals, nuts, root crops and other agricultural products. Silencing of five aflatoxin-synthesis genes by RNA interference (RNAi) in peanut plants was used to control aflatoxin accumulation following inoculation with A. flavus. Previously, no method existed to analyze the effectiveness of RNAi in individual peanut transgenic events, …
Mechanisms By Which Dietary Ellagic Acid Attenuates Obesity And Obesity-Mediated Metabolic Complications, Inhae Kang
Mechanisms By Which Dietary Ellagic Acid Attenuates Obesity And Obesity-Mediated Metabolic Complications, Inhae Kang
College of Education and Human Sciences: Dissertations, Theses, and Student Research
Ellagic acid (EA) is a polyphenol found in various fruits and plants, such as berries, pomegranates, muscadine grapes, nuts and bark of oak tree. EA has been known to exhibit anti-inflammatory and anti-proliferative effects in various types of cancer. However, little is known about the effects of EA on obesity. Herein, 1) the lipid-lowering role of EA was identified in primary human adipose stem cells (hASCs) and human hepatoma Huh7 cells; 2) the molecular mechanisms by which EA attenuates adipogenesis by epigenetic modification were identified; 3) the effects of EA on high fat and high sucrose-mediated obesity was …
Detection Methods And Intestinal Adherence Of Non-O157 Shiga Toxin-Producing Escherichia Coli, Zachary R. Stromberg
Detection Methods And Intestinal Adherence Of Non-O157 Shiga Toxin-Producing Escherichia Coli, Zachary R. Stromberg
School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research
Shiga toxin-producing Escherichia coli (STEC) are enteric pathogens of humans. Cattle serve as a reservoir and harbor STEC in their intestines. Intimin-positive STEC are referred to as enterohemorrhagic E.coli (EHEC). Seven serogroups (O26, O45, O103, O111, O121, O145, and O157) account for the majority of illness due to STEC and are hereafter referred to as STEC/EHEC-7. To improve detection, enrichment broths were compared for supporting growth of STEC-7 and STEC O104:H4 (STEC-8). In pure culture, STEC enriched in trypticase soy broth (TSB) had significantly greater growth compared to TSB containing antimicrobials. In fecal samples, E. coli broth enrichment yielded …

Whole-Genome Sequencing Of Kshv From Zambian Kaposi’S Sarcoma Biopsies Reveals Unique Viral Diversity, Landon N. Olp, Adrien Jeanniard, Clemence Marimo, John T. West, Charles Wood
Nebraska Center for Virology: Faculty Publications
Kaposi’s sarcoma-associated herpesvirus (KSHV) is the etiological agent for Kaposi’s sarcoma (KS). Both KSHV and KS are endemic in sub-Saharan Africa where approximately 84% of global KS cases occur. Nevertheless, whole-genome sequencing of KSHV has only been completed using isolates from Western countries—where KS is not endemic. The lack of whole-genome KSHV sequence data from the most clinically important geographical region, sub-Saharan Africa, represents an important gap as it remains unclear whether genomic diversity has a role on KSHV pathogenesis. We hypothesized that distinct KSHV genotypes might be present in sub-Saharan Africa compared to Western countries. Using a KSHV-targeted enrichment …

Nebraska Center for Virology: Faculty Publications
Background: The risk of Kaposi’s sarcoma–associated herpesvirus (KSHV) acquisition among children is increased by HIV infection. Antiretroviral therapy (ART) was recently made widely available to HIV-infected children in Zambia. However, the impact of early ART on KSHV transmission to HIV-infected children is unknown.
Methods: We enrolled and followed a cohort of 287 HIV-exposed, KSHV-negative children under 12 months of age from Lusaka, Zambia, to identify KSHV seroconversion events. Potential factors associated with KSHV infection—with an emphasis on HIV, ART, and immunological measures—were assessed through structured questionnaires and blood analyses. Incidence rate, Kaplan- Meier, and multivariable Cox regression models were used …

Secretion Of Heat-Labile Enterotoxin By Porcine-Origin Enterotoxigenic Escherichia Coli And Relation To Virulence, Prageeth Rukshan Wijemanne
School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research
Heat-labile enterotoxin (LT) is an important virulence factor secreted by some strains of porcine-origin enterotoxigenic Escherichia coli (pETEC). The prototypic human-origin strain H10407 secretes LT via a type II secretion system (T2SS), but its presence or importance in pETEC has not been established. Exposure of pETEC to glucose has been shown to result in different secretion levels of LT. Furthermore, the relationship between the level of LT secreted and the virulence potential of the respective pETEC strain has not been established. To determine the relationship between the capacity to secrete LT and virulence in wild-type (WT) pETEC, 16 strains isolated …
Should People Be More Educated On Type 1 Diabetes?, Adrianna Braggs
Should People Be More Educated On Type 1 Diabetes?, Adrianna Braggs
Nebraska College Preparatory Academy: Senior Capstone Projects
Many people know about so many diseases that are happening in the world today yet Type 1 Diabetes remains a mystery. Type I Diabetes (TD1) is an autoimmune disease in which a person’s pancreas stops producing insulin, a hormone that enables people to get enough energy from food. Research on this topic is important because many children and young adults are diagnosed with the disease yet the education is lacking.

Taxonomy And Molecular Epidemiology Of Echinococcus Granulosus Sensu Lato, Thomas Romig, Dennis Ebi, Marion Wassermann
Harold W. Manter Laboratory of Parasitology: Library Materials
Echinococcus granulosus, formerly regarded as a single species with a high genotypic and phenotypic diversity, is now recognized as an assemblage of cryptic species, which differ considerably in morphology, development, host specificity (including infectivity/pathogenicity for humans) and other aspects. This diversity is reflected in the mitochondrial and nuclear genomes and has led to the construction of phylogenetic trees and hypotheses on the origin and geographic dispersal of various taxa. Based on phenotypic characters and gene sequences, E. granulosus (sensu lato) has by now been subdivided into E. granulosus sensu stricto (including the formerly identified genotypic variants G1-3), …
Evolution Of Hematophagous Habit In Triatominae (Heteroptera: Reduviidae), Fernando Otálora-Luna, Antonio J. Pérez-Sánchez, Claudia Sandoval, Elis Aldana
Evolution Of Hematophagous Habit In Triatominae (Heteroptera: Reduviidae), Fernando Otálora-Luna, Antonio J. Pérez-Sánchez, Claudia Sandoval, Elis Aldana
Harold W. Manter Laboratory of Parasitology: Library Materials
All members of Triatominae subfamily (Heteroptera: Reduviidae), potential vectors of Trypanosoma cruzi, etiologic agent of the Chagas disease, feed on blood. Through evolution, these bugs have fixed special morphological, physiological, and behavioral aptations (adaptations and exaptations) adequate to feed on blood. Phylogeny suggests that triatomines evolved from predator reduvids which in turn descended from phytophagous hemipterans. Some pleisiomorphic traits developed by the reduvid ancestors of the triatomines facilitated and modeled hematophagy in these insects. Among them, mouthparts, saliva composition, enzymes, and digestive symbionts are the most noticeable. However, the decisive step that allowed the shift from predation to hematophagy …

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Multiple genetically and antigenically distinct hemagglutinin genes of the H1 and H3 influenza A virus (IAV) subtypes co-circulate in North American swine. This diversity has evolved by repeated transmission of IAVs from humans to swine and subsequent antigenic drift in swine. To understand the evolutionary dynamics of these diverse HA lineages in North American swine, we undertook a phylogenetic analysis of 1576 H1 and 607 H3 HA gene segments, as well as 834 N1 and 1293 N2 NA gene segments, and 2126 M gene segments. These data revealed yearly co-circulation of H1N1, H1N2, and H3N2 viruses, with three HA clades …

An intricate history of human dispersal and geographic colonization has strongly affected the distribution of human pathogens. The pig tapeworm Taenia solium occurs throughout the world as the causative agent of cysticercosis, one of the most serious neglected tropical diseases. Discrete genetic lineages of T. solium in Asia and Africa/Latin America are geographically disjunct; only in Madagascar are they sympatric. Linguistic, archaeological and genetic evidence has indicated that the people in Madagascar have mixed ancestry from Island Southeast Asia and East Africa. Hence, anthropogenic introduction of the tapeworm from Southeast Asia and Africa had been postulated. This study shows that …

Type I IFNs play an important role in innate and adaptive immunity against viral infections. A novel type I IFN, namely IFN-ε, which can protect against vaginal transmission of HSV2 and Chlamydia muridarum bacterial infection, has been described in mice and humans. Nevertheless, the principle cell type and the expression pattern of IFN-ε in tissues remain uncertain. In addition, the expression of IFN-ε in Indian rhesus macaques (Macaca mulatta) has not been reported. Here, we analyzed IFN-ε expression in multiple mucosal sites of uninfected or SIV-infected Indian rhesus macaques using IHCS. We report for the first time the …
