Identifying Non-Traditional Slippery Sequences Associated With Translational Frameshifts, Aaron J. Gin, Kari Lynn Clase

Graduate Industrial Research Symposium

Genetic frameshifts are a mutation in which
a nucleotide skip leads to a shift in the
reading frame. In viruses, these frameshifts
can be programmed using a slippery
sequence to bypass the stop codon
associated with the initial protein. This
allows for variable control of protein
expression. In bacteriophages, translational
frameshifts have been identified but only a
few have been proven experimentally. Using
experimental data and comparative
genomics, non-traditional slippery
sequences can be identified as assisting in
controlling the protein coding throughout
viruses. Novel slippery sequences can aid in
the understanding of protein expression in
biological environments and further the …

Fish Farming Wastewater Treatment Using Algae-Cyanobacterial Inocula, Yolanys Aranda

Graduate Industrial Research Symposium

Fish is one of the most important nutrient sources of the human diet, and its low-cost aquaculture production is advantageous. During processing, large quantities of organic and inorganic nutrients are produced. Discharging fish farming wastewater to the environment without proper treatment can support harmful algal growth. Therefore, aquaculture effluent must be treated prior to discharge to the receiving waters. In this study, six different cyanobacteria and algae species, including Chlorococcumminutum, Porphyridiumcruentum, Chlorella vulgaris, Microcystis aeruginosa, Chlamydomonas reinhardtii, and Fischerellamuscicola were studiedto treatfish aquaculture wastewater, using mix-culture bacteria as the inoccolum. All samples were incubated for 21 days. Parameters such as …

Evaluation Of Qpcr To Detect Shifts In Population Composition Of The Rhizobial Symbiont Mesorhizobium Japonicum During Serial In Planta Transfers, Kenjiro W. Quides, Yoobeen Lee, Teresa Hur, Hagop S. Atamian

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Microbial symbionts range from mutualistic to commensal to antagonistic. While these roles are distinct in their outcome, they are also fluid in a changing environment. Here, we used the Lotus japonicus–Mesorhizobium japonicum symbiosis to investigate short-term and long-term shifts in population abundance using an effective, fast, and low-cost tracking methodology for M. japonicum. We use quantitative polymerase chain reaction (qPCR) to track previously generated signature-tagged M. japonicum mutants targeting the Tn5 transposon insertion and the flanking gene. We used a highly beneficial wild type and moderately beneficial and non-beneficial mutants of M. japonicum sp. nov. to demonstrate the specificity …

Biology Faculty Articles

Deep water ports are human built coastal structures that by definition welcome ship traffic and disturbance. Evidence is accumulating that enhanced port activities such as dredging or deepening have negatively affected nearby natural habitats. Port Everglades Inlet (PEI) is a large active South Florida cargo port for over two million people and lies adjacent to coral reefs, dwindling mangroves, and recreational beaches. In this study, the microbial communities of PEI and adjacent reef sediments were characterized to serve as indicators for change due to dredging and assess anthropogenic influence on these sensitive ecosystems by sequencing the V4 region of 16S …

Metagenomic Insights Into The Full-Scale Anaerobic Digestion Of Cow Manure And Pre-Treated Food Waste, Amy Camille Decola

Graduate College Dissertations and Theses

Anaerobic digestion provides many benefits, such as diverting organic waste from landfills, promoting nutrient recovery, reducing greenhouse gas emissions, and producing renewable energy. A complex community of microorganisms is responsible for the anaerobic digestion process that converts organic matter into biogas, a renewable energy source. The start-up phase of an anaerobic digester is considered a crucial point in solidifying the core microbial community that will ensure a stable anaerobic digester. A full-scale anaerobic digester that co-digests cow manure and pre-treated food waste from a hydrolysis tank was studied from start-up through stable performance in order to better understand the dynamics …

Host-Pathogen Interactions In A Changing World: Microbes, Mucosal Defenses, And Multiple Hosts, Brandon C. Labumbard

Graduate Doctoral Dissertations

As fungal diseases continue to emerge, research increasingly focuses on host-microbiome interactions and links to disease. Certain skin-associated microbes may benefit hosts by protecting them from invading pathogens. Seasonal changes in the host environment can also result in shifts in the microbial community and pathogen virulence – potentially influencing disease dynamics. I investigated how cutaneous microbial communities differ across hosts, seasons, and Batrachochytrium dendrobatidis (Bd) infection status by sequencing the microbial communities of 1,100 leopard frogs at five locations across the US. Percent anti-Bd function varied seasonally and with Bd infection status. Bacterial communities also varied across locations and time. …

Prevalence And Plasmid Profiles Of Enterobacteriaceae Isolates Obtained From Individuals With Asymptomatic Bacteriuria In Okada, Edo State, Nigeria, Osarumwense Precious Otote, Maureen Uchechukwu Okwu, Osazee Ekundayo Izevbuwa, Happy Ovuerhi Oferiofe

Makara Journal of Science

Asymptomatic bacteriuria (ASB) is the presence of bacteria in apparently healthy individuals. Although, the prevalence varies widely with age, gender, and the presence or absence of genitourinary abnormalities, the detection of pathogenic bacteria in urine constitutes firm evidence of infection. The objectives of this study were to isolate members of the family Enterobacteriaceae from urine samples of research participants, and to determine the antibacterial susceptibility and plasmid profiles of the isolates. A total of 122 mid-stream urine samples consisting of 72 male and 50 female participants from selected primary and secondary schools were collected. The age of the participants used …

Rapid Bacterial And Fungal Successional Dynamics In First Year After Chaparral Wildfire, M. Fabiola Pulido-Chavez, James W. J. Randolph, Cassandra A. Zalman, Loralee Larios, Peter M. Homyak, Sydney I. Glassman

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

The rise in wildfire frequency and severity across the globe has increased interest in secondary succession. However, despite the role of soil microbial communities in controlling biogeochemical cycling and their role in the regeneration of post-fire vegetation, the lack of measurements immediately post-fire and at high temporal resolution has limited understanding of microbial secondary succession. To fill this knowledge gap, we sampled soils at 17, 25, 34, 67, 95, 131, 187, 286, and 376 days after a southern California wildfire in fire-adapted chaparral shrublands. We assessed bacterial and fungal biomass with qPCR of 16S and 18S and richness and composition …

The Role Of Dha In The Impact Of Trem2 On Microglia Activation And Alzheimer’S Disease, Michael A. Palmieri Iii

Seton Hall University Dissertations and Theses (ETDs)

Alzheimer’s disease (AD) is a neurological disease that is associated with microglia activation. An important receptor involved in microglia activation is Triggering receptor expressed on myeloid cells 2 (TREM2). Recent studies suggest that docosahexaenoic acid (DHA) could reduce the neuroinflammation that is associated with microglia activation. We hypothesized that when DHA concentration was increased, TREM2 expression would decrease, microglia activity would be inhibited, and a resulting decrease in neuroinflammation would be observed. We examined peer-reviewed journal articles from 2017-2022 that investigated the relationship between TREM2 activation and severity of AD symptoms, the protective properties of DHA against AD, and the …

The Enemy Within: An Investigation Of The Intracellular Bacteria In Urinary Tract Infections, Jennie Elizabeth Hazen

Arts & Sciences Electronic Theses and Dissertations

Urinary tract infections (UTIs) are common diseases that are associated with significant morbidities. Multiple studies have indicated that multiple species of uropathogenesis bacteria invade and persist within bladder epithelial cells as a necessary step of uropathogenesis. Interestingly, many of these species are not canonically associated with intracellular infections. Although the first study describing bacteria within the urothelium was published two decades ago, this critical step of uropathogenesis remains relatively understudied.

I established a murine model of community-acquired A. baumannii UTI, a previously unstudied manifestation of the disease. While immunocompetent mice resolved their infections quickly, immunocompromised mice displayed high bacterial burdens …
