Adenoviral-Vectored Centralized Consensus Hemagglutinin Vaccine Provides Broad Protection Against H2 Influenza A Virus, Erika M. Petro-Turnquist, Brianna L. Bullard, Matthew J. Pekarek, Eric A. Weaver

Nebraska Center for Virology: Faculty Publications

Several influenza pandemics have occurred in the past century, one of which emerged in 1957 from a zoonotic transmission of H2N2 from an avian reservoir into humans. This pandemic caused 2–4 million deaths and circulated until 1968. Since the disappearance of H2N2 from human populations, there has been waning immunity against H2, and this subtype is not currently incorporated into seasonal vaccines. However, H2 influenza remains a pandemic threat due to consistent circulation in avian reservoirs. Here, we describe a method of pandemic preparedness by creating an adenoviral-vectored centralized consensus vaccine design against human H2 influenza. We also assessed the …

Effectiveness Of Stricter Vaccine Mandates In Public Schools And Childcare Centers, Anna Ferentinos

Emerging Writers

Vaccines have been a controversial and frequently discussed topic the last two years due to the COVID-19 pandemic. The amount of readily available information on the internet - accurate or not – has led to many theories and opinions on whether to vaccinate and why, or why not. This article discusses these theories, as well as the benefits and consequences of vaccine mandates, with the help of examples from other countries. The author argues that a federal vaccine mandate should be implemented in the United States of America so as to encourage parents to protect children through scheduled immunizations.

Decoding The Mystery Of Antibiotic Persistence, Tahmina Hossain

Electronic Theses and Dissertations

This work combines microbiology, molecular biology, Next-Generation Sequencing and system biology approaches to explore the mechanism of antibiotic persistence: a multi-drug tolerant, non-dividing, and metabolically altered state present in a subpopulation of cells due to phenotypic diversity rather than genetic variation (i.e. mutations). Persister can survive lethal antibiotic state and resuscitate after the treatment period is over. They are considered as the major contributing factor behind recurring infections. They also have a high mutation rate, which increases the chances of bacteria gaining antibiotic resistance. The formation of this phenotypic variant (persister) threatens the therapeutic effectiveness of antibiotics and understanding how …

Expanding Mouse-Adapted Yamagata-Like Influenza B Viruses In Eggs Enhances In Vivo Lethality In Balb/C Mice, Matthew J. Pekarek, Erika M. Petro-Turnquist, Adam Rubrum, Richard J. Webby, Eric A. Weaver

Nebraska Center for Virology: Faculty Publications

Despite the yearly global impact of influenza B viruses (IBVs), limited host range has been a hurdle to developing a readily accessible small animal disease model for vaccine studies. Mouseadapting IBV can produce highly pathogenic viruses through serial lung passaging in mice. Previous studies have highlighted amino acid changes throughout the viral genome correlating with increased pathogenicity, but no consensus mutations have been determined. We aimed to show that growth system can play a role in mouse-adapted IBV lethality. Two Yamagata-lineage IBVs were serially passaged 10 times in mouse lungs before expansion in embryonated eggs or Madin–Darby canine kidney cells …

Dissecting The Cellular Landscape And Transcriptome Network In Viral Myocarditis By Single-Cell Rna Sequencing, Ninaad Lasrado, Nicholas Borcherding, Rajkumar Arumugam, Timothy K. Starr, Jay Reddy

School of Veterinary and Biomedical Sciences: Faculty Publications

Coxsackievirus B3 (CVB3)-induced myocarditis is commonly employed to study viral pathogenesis in mice.Chronically affected micemaydevelop dilated cardiomyopathy, which may involve the mediation of immune and nonimmune cells. To dissect this complexity, we performed single-cell RNA sequencing on heart cells from healthy and myocarditic mice, leading us to note significant proportions of myeloid cells, T cells, and fibroblasts. Although the transcriptomes of myeloid cells were mainly of M2 phenotype, the Th17 cells, CTLs, and Treg cells had signatures critical for cytotoxic functions. Fibroblasts were heterogeneous expressing genes important in fibrosis and regulation of inflammation and immune responses. The intercellular communication networks …

Creation Of A Global Vaccine Risk Index, Tasmiah Nuzhath, Peter J Hotez, Ashish Damania, P Shuling Liu, Brian Colwell

Center for Medical Ethics and Health Policy Staff Publications

The World Health Organization has identified vaccine hesitancy as one of its top ten global health threats for 2019. Efforts are underway to define the factors responsible for reductions in vaccine confidence. However, as global measles cases accelerated beginning in 2018, it became evident that additional factors were promoting measles re-emergence, including war, political and socio-economic collapse, shifting poverty, and vulnerability to weather events and climate change. Accordingly, we propose a Global Vaccine Risk Index (VRI) to consider these variables as a more comprehensive means to identify vulnerable nations where we might expect measles and other vaccine-preventable diseases to emerge …

Diagnosis And Interpretation Of Testing For Cat Scratch Disease, Nasim Khalfe, Doris Lin

Faculty, Staff and Students Publications

Cat scratch disease (CSD) is an infectious disease caused by Bartonella henselae that presents as regional lymphadenopathy which can appear within weeks after a cat scratch. There is no gold standard for diagnosis. Rather, clinicians rely on an amalgam of criteria to make a definitive diagnosis. We describe a case of a 44-year-old woman with six cats who presented with a painful left inguinal mass, had splenic lesions on imaging, and had positive serology but a negative polymerase chain reaction test for B. henselae.

Faculty, Staff and Students Publications

OBJECTIVES: We characterized antibiotic prescribing patterns and management practices among recurrent urinary tract infection (rUTI) patients, and we identified factors associated with lack of guideline adherence to antibiotic choice, duration of treatment, and urine cultures obtained. We hypothesized that prior resistance to nitrofurantoin or trimethoprim-sulfamethoxazole (TMP-SMX), shorter intervals between rUTIs, and more frequent rUTIs would be associated with fluoroquinolone or β-lactam prescribing, or longer duration of therapy.

METHODS: This study was a retrospective database study of adult women with

RESULTS: Among 214 patients with 566 visits, 61.5% of prescriptions comprised first-line agents of nitrofurantoin (39.7%) and TMP-SMX (21.5%), followed by …

Rotavirus-Induced Lipid Droplet Biogenesis Is Critical For Virus Replication, Jeanette M Criglar, Mary K Estes, Sue E Crawford

Faculty, Staff and Students Publications

A variety of pathogens, including viruses, bacteria and parasites, target cellular lipid droplets for their replication. Rotaviruses (RVs) infect the villous epithelium of the small intestine and are a major cause of acute gastroenteritis in infants and young children worldwide. RVs induce and require lipid droplets for the formation of viroplasms, sites of virus genome replication, and nascent particle assembly. Here we review the role of lipid droplets in RV replication. Inhibitors of fatty acid synthesis or chemicals that interfere with lipid droplet homeostasis decrease the number and size of viroplasms and the yield of infectious virus. We used a …

Classification Of Bacteria And Fungi In Peritoneal Dialysis Fluids Of Patients With Chronic Kidney Disease Based On Metagenomic Analysis, Suthida Visedthorn

Chulalongkorn University Theses and Dissertations (Chula ETD)

Chronic kidney disease (CKD) is a long-term condition where sustained damage of the renal parenchyma leads to the chronic deterioration of renal function that may gradually progress to end-stage kidney disease (ESKD). Peritoneal dialysis (PD) is a type of ESKD treatment that is beneficial to improve a patient's quality of life. However, PD-associated peritonitis is a major complication that contributes cause of death, and the detection of the pathogen provided a high culture-negative rate. This study aims to apply metagenomic approaches for identifying the bacteria and fungi in peritoneal dialysis effluent (PDE) of CKD patients based on the full-length 16S …

Identification Of Subclinical Iron Deficiency Using New Erythrocytes, Leukocytes, And Reticulocytes Parameters During Nonsevere Acute Infection In Pediatric Outpatients, Nazmi̇ Mutlu Karakaş, Serap Ki̇rki̇z Kayali, Zühre Kaya

Turkish Journal of Medical Sciences

Background/aim: This study aims to investigate the diagnostic utility of new erythrocytes, leukocytes, and reticulocytes parameters for the identification of subclinical iron deficiency (ID) in children under 6 years with nonsevere acute infection in pediatric outpatients. Materials and methods: The study included 102 children with acute infections and 31 true ID. Traditional and new hematology parameters were measured in a Sysmex-XN® , along with C-reactive protein level, and iron parameters. Participants? ID were categorized as: the ferritin < 100 ng/mL, transferrin saturation < 20% was defined as ?subclinical or functional ID (FID) in Group 1?; ferritin < 30 ng/mL, transferrin saturation < 20%, as ?absolute-ID (AID)? in Group 2; ferritin < 12 ng/mL without anemia and infection, as ?true ID? in Group 3. Results: The frequencies of FID and AID among the 102 children with acute infection were 24% and 76%, respectively. Compared with the Group 2 patients, Group 1 had a significantly higher mean percentage of hypochromic erythrocytes (Hypo-He), and significantly lower levels of hemoglobin (Hb) and Hb content of reticulocytes (RET-He) (p < 0.05 for all). Compared with Group 2 and Group 3 patients, Group 1 had a significantly higher mean percentage of immature reticulocyte fraction (IRF) and immature granulocyte (IG) values (p < 0.05 for all). The RET-He, IRF%, Hypo-He%, and IG% cut-off values for predicting FID during infection were 27.0 pg, 10.6%, 2.5%, and 0.35% respectively. Conclusion: The RET-He, Hypo-He, IRF, and IG may be useful parameters for identifying subclinical ID in small children with nonsevere acute infection in pediatric outpatients.
