Chapter 1

Mycobacterium avium complex (MAC) has become one of the major problems in public health and livestock. Members of MAC, such as M. avium subsp paratuberculosis (MAP) and M. avium subsp hominissuis (MAH), are responsible for many opportunistic infections and the loss of livestock. MAP is economically significant to the beef and dairy industries because it is the etiologic agent of Johnes’s disease, a chronic and fatal enteritis in ruminants. Tracing the infection sources of MAC could be difficult since it infects many types of hosts in the natural environment. Furthermore, there is less information known about MAP pathogenicity …

Zika Virus Induces Apoptosis In Retinal Pigmented Epithelial Cells, Madison Kraus, Philma Glora Muthuraj, Sathish Kumar Natarajan

Zika virus is a single-stranded positive sense RNA virus that attracted international attention in 2015 when an epidemic broke out in Brazil. This vector borne virus is transmitted by mosquitos and is especially concerning for pregnant women because the virus can affect the development of the fetus. One known complication is the destruction of infected retinal epithelial cells. The transduction of light is interrupted due to cell death and results in blind spots. Previous research has demonstrated that palmitoleate can reduce the observed levels of apoptosis in ZIKAV infected JEG-3 cells. We have also seen the protection of retinal pigmented …

Assembly And Identification Of Novel Viruses In The Aquatic Invertebrate Daphnia Magna, Freddy L. Gonzalez, Reilly O. Cooper, Clayton E. Cressler

Microbiome studies have been critical to understanding host health and life history. Many studies primarily focus on understanding the impacts of bacteria on the host, while fewer examine the impacts of viruses on host fitness or the interaction between viruses and bacteria within a host. Here, we utilized shotgun sequencing to identify whether viruses were present in the model organism Daphnia magna. VIBRANT, a bioinformatic tool that utilizes hybrid machine learning and protein similarity to identify lytic genomes and other novel viruses, was used on sequencing data from four samples of adult and juvenile Daphnia. We found a …

Creation Of An Influenza B Epigraph Vaccine, Leigh Jahnke, Kristine Hoagstrom, Eric A. Weaver

The CDC struggles to predict the upcoming influenza viruses resulting in an ineffective influenza vaccine. The 2019 – 2020 influenza vaccine provides an example of vaccine mismatch where the vaccine poorly matches the circulating influenza strains. We have created Influenza B Epigraph hemagglutinin (HA) immunogens that are computationally designed to select the greatest coverage of B and T cell epitopes in the natural population. Our preliminary data shows Epigraph immunogens induce superior cross-reactive antibody responses, overall T cell immunity, breadth of T cell epitopes, and protection against influenza virus. The primary goal of this study is to clone the influenza …
