Hyperparasitic Spore-Forming Eukaryotes (Microsporidia, Haplosporidia, And Myxozoa) Parasitizing Trematodes (Platyhelminthes), Yuliya Ya. Sokolova, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Library Materials

ABSTRACT

Trematodes serve as outstanding hosts for a variety of parasites. This paper restricts those parasites to three groups of non-related taxa parasitizing trematodes and forming invasive spores similar in external morphology, which is why in the past these three groups of parasitic eukaryotes were united into the taxon “Sporozoa” (Kudo, 1924). (1) Trematode-infecting microsporidia (type Microsporidia Balbiani, 1882: Rozellomycota: Holomycota) are represented by more than 30 species. Among those, the species with sequenced barcode (SSU rDNA) are phylogenetically associated with either microsporidia from invertebrates, as the species of the genus Unikaryon (7 species), or fish microsporidia, as the species …

Background

Over the last decade, the rapid development of high-throughput sequencing platforms has accelerated species description and assisted morphological classification through DNA barcoding. However, the current highthroughput DNA barcoding methods cannot obtain full-length barcode sequences due to read length limitations (for example, a maximum read length of 300 bp for the Illumina’s MiSeq system), or are hindered by a relatively high cost or low sequencing output (e.g. a maximum number of eight million reads per cell for the PacBio’s SEQUEL II system).

Results

Pooled cytochrome c oxidase subunit I (COI) barcodes from individual specimens were sequenced on the …

Polyanhydride Nanoparticles Induce Low Inflammatory Dendritic Cell Activation Resulting In Cd8+ T Cell Memory And Delayed Tumor Progression, Ross Darling, Sujata Senapati, John Christiansen, Luman Liu, Amanda E. Ramer-Tati, Balaji Narasimhan, Michael Wannemuehler

Department of Food Science and Technology: Faculty Publications

Introduction: Adjuvants and immunotherapies designed to activate adaptive immunity to eliminate infectious disease and tumors have become an area of interest aimed at providing a safe and effective strategy to prevent or eliminate disease. Existing approaches would benefit from the development of immunization regimens capable of inducing efficacious cell- mediated immunity directed toward CD8+ T cell-specific antigens. This goal is critically dependent upon appropriate activation of antigen-presenting cells (APCs) most notably dendritic cells (DCs). In this regard, polyanhydride particles have been shown to be effectively internalized by APCs and induce activation.

Methods: Here, a prophylactic vaccine regimen designed as a …

Department of Food Science and Technology: Faculty Publications

The gastrointestinal microbiome plays an important role in limiting susceptibility to infection with Clostridioides difficile. To better understand the ecology of bacteria important for C. difficile colonization resistance, we developed an experimental platform to simplify complex communities of fecal bacteria through dilution and rapidly screen for their ability to resist C. difficile colonization after challenge, as measured by 􏰀100-fold reduction in levels of C. difficile in challenged communities. We screened 76 simplified communities diluted from cultures of six fecal donors and identified 24 simplified communities that inhibited C. difficile colonization in vitro. Sequencing revealed that simplified communities were composed of …

Expression Profiling Of Human Milk Derived Exosomal Micrornas And Their Targets In Hiv‐1 Infected Mothers, Muhammad Atif Zahoor, Mcmaster University, Hamilton, Bethany M. Henrick, Chris P. Verschoor, Alash’Le Abimiku, Sophia Osawe, Kenneth L. Rosenthal

Department of Food Science and Technology: Faculty Publications

Despite the use of antiretroviral therapy (ART) in HIV‐1 infected mothers approximately 5% of new HIV‐1 infections still occur in breastfed infants annually, which warrants for the development of novel strategies to prevent new HIV‐1 infections in infants. Human milk (HM) exosomes are highly enriched in microRNAs (miRNAs), which play an important role in neonatal immunity. Furthermore, HM exosomes from healthy donors are known to inhibit HIV‐1 infection and transmission; however, the effect of HIV‐1 on HM exosomal miRNA signatures remains unknown. In this study, we used nCounter NanoString technology and investigated miRNAs expression profiles in first week postpartum HM …

Hiv-1 Subtypes And Drug Resistance Mutations Among Female Sex Workers Varied In Different Cities And Regions Of The Democratic Republic Of Congo, Eun Hee Kwon, Godefroid M. A. Musema, Jessica Boelter, Sydney Townsend, Desire Tshala-Katumbay, Patrick K. Kayembe, John T. West, Charles Wood

Nebraska Center for Virology: Faculty Publications

Background Complex mosaic structures of HIV-1 were found in the Democratic Republic of Congo (DRC). Currently, there is limited information on the circulating HIV-1 strains, the distribution of these strains and antiretroviral (ART) resistant viruses in different regions of the country, and the HIV-1 strains harbored by the high-risk groups like female sex workers (FSW) reported to be the source of recombinant and ART resistant viruses.

Methods Dried Blood Spots (DBS), collected from 325 infected FSWs in ten cities from 2012 DRC HIV/STI Integrated Biological and Behavioral Surveillance Survey, were tested for HIV-1 genotypes and antiretroviral resistance mutations. Regional segregation …

How The Cervical Microbiota Contributes To Cervical Cancer Risk In Sub-Saharan Africa, Cameron Klein, Crispin Kahesa, Julius Mwalselage, John T. West, Charles Wood, Peter C. Angeletti

Nebraska Center for Virology: Faculty Publications

Despite ongoing efforts, sub-Saharan Africa faces a higher cervical cancer burden than anywhere else in the world. Besides HPV infection, definitive factors of cervical cancer are still unclear. Particular states of the cervicovaginal microbiota and viral infections are associated with increased cervical cancer risk. Notably, HIV infection, which is prevalent in sub-Saharan Africa, greatly increases risk of cervicovaginal dysbiosis and cervical cancer. To better understand and address cervical cancer in sub-Saharan Africa, a better knowledge of the regional cervicovaginal microbiome is required This review establishes current knowledge of HPV, HIV, cervicovaginal infections, and the cervicovaginal microbiota in sub-Saharan Africa. Because …

The Kaposi’S Sarcoma-Associated Herpesvirus (Kshv) Gh/Gl Complex Is The Predominant Neutralizing Antigenic Determinant In Kshv-Infected Individuals, Yasaman Mortazavi, Salum J. Lidenge, Tara Tran, John T. West, Charles Wood, For Yue Tso

Nebraska Center for Virology: Faculty Publications

Kaposi’s sarcoma-associated herpesvirus (KSHV) is the etiological agent of Kaposi’s sarcoma (KS), one of the most prevalent cancers of people living with HIV/AIDS in sub-Saharan Africa. The seroprevalence for KSHV is high in the region, and no prophylactic vaccine against the virus is available. In this study, we characterized the antigenic targets of KSHV-specific neutralizing antibodies (nAbs) in asymptomatic KSHV-infected individuals and KS patients with high nAbs titers. We quantified the extent to which various KSHV envelope glycoproteins (gB, ORF28, ORF68, gH, gL, gM, gN and gpK8.1) adsorbed/removed KSHV-specific nAbs from the plasma of infected individuals. Our study revealed that …

Mycoplasma Co-Infection Is Associated With Cervical Cancer Risk, Cameron Klein, Kandali Samwel, Crispin Kahesa, Julius Mwaiselage, John T. West, Charles Wood, Peter C. Angeletti

Nebraska Center for Virology: Faculty Publications

Tanzania faces one of the highest cervical cancer burdens in the world. Recent work has suggested that the bacterial family Mycoplasmataceae is associated with higher levels of human papillomavirus (HPV), human immunodeficiency virus (HIV), and pre-cancerous cervical lesions. Mycoplasmataceae infection in Tanzania is not well understood, especially when considering the differences between sexually transmitted species of Mycoplasmataceae. To establish the prevalence of common Mycoplasmataceae cervical infections and evaluate their relationship with risk factors for cervical cancer, 1160 Tanzanian women responded to an epidemiological questionnaire and were tested for HIV, HPV, cervical lesions, Mycoplasma genitalium, Mycoplasma hominis, Ureaplasma spp., and Lactobacillus …

Epstein Barr Virus-Immortalizedｂlymphocytes Exacerbate Experimental Autoimmune Encephalomyelitis In Xenograft Mice, Pascal Polepole, Alison Bartenslager, Yutong Liu, Thomas M. Petro, Samodha C. Fernando, Luwen Zhang

Nebraska Center for Virology: Faculty Publications

Multiple sclerosis (MS) is the most common autoimmune disorder affecting the central nervous system. Epstein-Barr virus (EBV) is a causative agent for infectious mononucleosis (IM) that is associated with MS pathogenesis. However, the exact mechanism by which EBV, specifically in IM, increases the risk for MS remains unknown. EBV immortalizes primary B lymphocytes in vitro and causes excessive B lymphocyte proliferation in IM in vivo. In asymptomatic carriers, EBV-infected B lymphocytes still proliferate to certain degrees, the process of which is tightly controlled by the host immune systems. Experimental autoimmune encephalomyelitis (EAE) mimics key features of MS in humans and …

A Decade In Review: A Systematic Review Of Universal Influenza Vaccines In Clinical Trials During The 2010 Decade, Brigette N. Corder, Brianna L. Bullard, Gregory Poland, Eric A. Weaver

Nebraska Center for Virology: Faculty Publications

On average, there are 3–5 million severe cases of influenza virus infections globally each year. Seasonal influenza vaccines provide limited protection against divergent influenza strains. Therefore, the development of a universal influenza vaccine is a top priority for the NIH. Here, we report a comprehensive summary of all universal influenza vaccines that were tested in clinical trials during the 2010–2019 decade. Of the 1597 studies found, 69 eligible clinical trials, which investigated 27 vaccines, were included in this review. Information from each trial was compiled for vaccine target, vaccine platform, adjuvant inclusion, clinical trial phase, and results. As we look …

Species D Adenoviruses As Oncolytic Viral Vectors, Brianna L. Bullard, Brigette N. Corder, Eric A. Weaver

Nebraska Center for Virology: Faculty Publications

Oncolytic adenoviruses (Ad) have shown promising results in the therapeutic treatment of cancer. Ad type 5 (Ad5) is the most extensively utilized Ad type. However, several limitations exist to using Ad5 as an oncolytic virus, including high levels of anti-Ad5 neutralizing antibodies in the population, binding of the Ad5 hexon to blood coagulation factor X leading to liver sequestration and toxicity, and reduced expression of the primary receptor CAR on many tumors. Here, we use in vitro methods to explore the oncolytic potential of four alternative Ad types (Ad26, 28, 45, and 48) belonging to the species D Ad subgroup …

Recommendations For Measuring Hiv Reservoir Size In Cure- Directed Clinical Trials., Luis J. Montaner, Qingsheng Li

Nebraska Center for Virology: Faculty Publications

Therapeutic strategies are being clinically tested either to eradicate the latent HIV reservoir or to achieve virologic control in the absence of antiretroviral therapy (ART). Attaining this goal will require a consensus on how best to measure the levels of persistently-infected cells with the potential to cause viral rebound upon ART cessation to assess the results of cure-directed strategies in vivo. Current measurements assess different aspects of the HIV provirus and its functionality, and produce divergent results. Here, we provide the collective insight and position from the BEAT-HIV Martin Delaney Collaboratory on which viral measurements to prioritize in HIV cure-directed …

Variation Profile Of The Orthotospovirus Genome, Deepti Nigam, Hernan Garcia Ruiz

Department of Plant Pathology: Faculty Publications

Orthotospoviruses are plant-infecting members of the family Tospoviridae (order Bunyavirales), have a broad host range and are vectored by polyphagous thrips in a circulative- propagative manner. Because diverse hosts and vectors impose heterogeneous selection constraints on viral genomes, the evolutionary arms races between hosts and their pathogens might be manifested as selection for rapid changes in key genes. These observations suggest that orthotospoviruses contain key genetic components that rapidly mutate to mediate host adaptation and vector transmission. Using complete genome sequences, we profiled genomic variation in orthotospoviruses. Results show that the three genomic segments contain hypervariable areas at homologous locations …

Uterine Torsion Dystocia Complicated By Perosomus Elumbis In An Angus Calf Associated With A Consanguineous Mating, Alyssa B. Helms, Riley E. Thompson, Sam Lawton, Jessica L. Petersen, Allison Watson, Mee-Ja Sula, David J. Steffen, Brian K. Whitlock

School of Veterinary and Biomedical Sciences: Faculty Publications

A six-year-old multiparous Angus cow was presented for dystocia. Vaginal and rectal examinations revealed an approximately 360° counterclockwise uterine torsion. The torsion was corrected by rolling the cow counterclockwise (three episodes) with the aid of a plank coupled with manual detorsion via the vagina. The placement of obstetric chains followed by manual traction ultimately delivered a stillborn male calf with evidence of vertebral aplasia, arthrogryposis, and abdominal organ herniation. Patient history and subsequent parentage verification revealed that the calf was the result of a consanguineous (mother to son) mating. Tissue samples from the affected calf and blood samples from the …

Identification Of Immunogenic Epitopes That Permit The Detection Of Antigen-Specific T Cell Responses In Multiple Serotypes Of Group B Coxsackievirus Infections, Ninaad Lasrado, Arunakumar Gangaplara, Rajkumar Arumugam, Chandirasegara Massilamany, Sayli Pokal, Yuzhen Zhou, Shi-Hua Xiang, David Steffen, Jay Reddy

School of Veterinary and Biomedical Sciences: Faculty Publications

Coxsackievirus group B (CVB) contains six serotypes that can affect various organs. Some of these organ-specific diseases such as myocarditis and pancreatitis can be caused by more than one serotype. Thus, development of immunological tools common to multiple serotypes is desired. This is especially critical for analyzing antigen-specific T cell responses at a single cell level. To this end, we made efforts to identify the immunogenic epitopes of CVB3 leading us to localize three T cell epitopes within the viral protein 1 (VP1) namely, VP1 681–700, VP1 721–740 and VP1 771–790. First, we confirmed their immunogenicity in the immunization settings. …

School of Veterinary and Biomedical Sciences: Faculty Publications

Reported cases of Lyme disease in Nebraska have been assumed to be imported from other endemic areas. Previous surveillance efforts provided no evidence of established populations as only individual specimens of Ixodes scapularis (Say) had been collected. In the winter of 2018, adult I. scapularis were found on a dog at Two Rivers State Recreation Area, Douglas County, prompting tick collection at the site and nearby natural areas. In May 2019, all life stages of host-seeking I. scapularis were collected using dragging and flagging techniques in sites located near the Platte River in Douglas, Sarpy, and Saunders counties. This is …
