Evaluating The Importance Of Biosecurity In Swine Operations, Lindsey Lemley, Lilly Rogers, Austin Calhoun
ATU Research Symposium
Swine health is critical to maintaining a profitable and productive swine operation. Biosecurity and sanitation are important practices that help maintain herd health. This study aimed to discover how biosecurity protocols and management practices differ between swine operations of different sizes. With diseases such as Porcine Reproductive and Respiratory Syndrome Virus (PRRSV), Brucellosis, and Porcine Circovirus type 2 (PCV2) being common in the swine industry, a strong biosecurity protocol protects swine farmers from financial losses associated with disease outbreaks. In 2004 alone, the estimated financial loss to PRRSV was over $761 million. Data concerning biosecurity and sanitation was collected from …

Convolutional Neural Network Based Analysis - An Aid To Diagnose Bacterial And Fungal Osteomyelitis, Saiprasad Alva, Dominic Augustine, Sowmya Sv, Mukul Saini, Sanjana Shetty
Annual Research Symposium
Osteomyelitis may be classified as Bacterial (Actinomycotic), Fungal (Mucormycotic), or combined based on the etiological agent. During histopathological examination, there is a high chance that bacterial colonies or fungal hyphae may be missed by the human eye, especially when there is a paucity of organisms. This may lead to a faulty diagnosis of the type of osteomyelitis which along with an improper treatment plan would cause further progression of the disease and various other complications. Therefore, the diagnosis of the exact etiological variant of osteomyelitis is of prime importance to design an appropriate treatment plan. In the present study, bone …

Genomic Diversity And Carbohydrate Utilisation In Human-Associated Bifidobacterial Isolates, Ortensia Catalano Gonzaga
ORBioM (Open Research BioSciences Meeting)
Bifidobacteria are beneficial commensals of the human gastrointestinal tract and their presence in the gut has been associated with positive health effects on the host. They account for a vast proportion of the infant gut microbiota, when the infant is fed on a milk-based diet, with their number progressively decreasing in adult and elderly. The gut microbiota and associated metabolic activities significantly impact on human health by promoting appropriate development of the infant immune system and contributing to the maintenance of the intestinal homeostasis. In recent years it has become clear that microbial colonization of the gut immediately following birth …
Urobiome Screening For Antimicrobial Peptides Against Uropathogenic Escherichia Coli, Jennifer Jones
Urobiome Screening For Antimicrobial Peptides Against Uropathogenic Escherichia Coli, Jennifer Jones
ORBioM (Open Research BioSciences Meeting)
BACKGROUND: Urinary tract infections (UTIs) are one of the most common bacterial infections worldwide. As global incidences of UTIs caused by multidrug resistant bacteria continue to increase, so too does the demand for novel antimicrobial therapies.
Due to its relatively understudied nature, the urinary microbiome represents a niche with an untapped source of potentially novel antimicrobials (e.g., bacteriocins). Improvements to bacterial culturing and sequencing techniques have highlighted these potential alternative treatments and control strategies to target antibiotic resistant uropathogenic E. coli (UPEC).
METHODS: Expanded quantitative urine culture (EQUC) was used to culture bacterial isolates from mid-stream urine samples. Urinary isolates …

Characterization Of Epithelial Growth Factor Transcripts Identified In Crotalus Atrox Venom, Ivan Lopez, Ying Jia
Research Symposium
Epithelial Growth Factor (EGF) is the primary source in regeneration and stimulation of essential fibroblasts cells commonly found in epithelium. Studies have shown that snake venom components are becoming a growing factor in treating illnesses such as cancer, muscular dystrophy, chronic pain, blood pressure, blood clotting, etc. EGF in human cells contains a promising quaternary structure that can bind to snake venom metalloproteinases, proposing a means of activating biochemical responses through protein-protein interactions to regulate unwanted cellular functions. This supports promising research in achieving a greater understanding of regulation along cellular pathways through ligands, increasing the likelihood of targeting unwanted …

Aging Manuka Honey Improves Antimicrobial Activity Against Pathogenic Bacteria, Rayna M. Carlson
Aging Manuka Honey Improves Antimicrobial Activity Against Pathogenic Bacteria, Rayna M. Carlson
2023 Symposium
Manuka honey (MH) has been documented to possess powerful anti-microbial properties through multiple mechanisms. These mechanisms include a low pH, high osmolarity, iron chelation, and its unique manuka factor (UMF), methylglyoxal (MGO). Although MGO is purported to be a major pillar in the honey’s antimicrobial properties, its activity is variable against different bacterial species. We hypothesize that MH’s other antimicrobial mechanisms may also exhibit variable activity against different bacterial species. Preliminary experiments to determine the Manuka honey minimum inhibitory concentrations (MIC) for bacterial species, Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus, suggested that some Manuka honey antimicrobial mechanisms …

The Effects Of Light Intensity On Cell Population And Oxygen Production Of Arthrospira Platensis, Sophia Ward, Cole Turner
Scholars Day Conference
As space exploration becomes more advanced, scientists look to find new ways to create nourishment and oxygen to maintain long-term space travel. Arthrospira platensis, commonly known as Spirulina, could be a possible solution to these problems. This cyanobacterium converts carbon dioxide into pure oxygen and the cell structure (coiled or straight) appears to trigger different oxygen and cultivation responses. Mixed (coiled and straight, Fig. 4) and coiled (Fig. 5) Spirulina cultures were transferred into 2.5 L containers and placed in white light boxes with varying intensities of light: 15 µmol/㎡/s, 7 µmol/㎡/s, and 3 µmol/㎡/s. Each experiment lasted 72 hours …

The Effects Of Light Intensity And Cell Structure On The Cultivation Of Arthrospira Platensis, Taylor Barnhart
Scholars Day Conference
As scientists explore further into space, more cost-effective resources are needed for long-term space travel. An interesting solution is Arthrospira platensis, a filamentous cyanobacteria high in proteins and nutrients, and known for its helical structure. In unfavorable conditions, coiled spirulina cells become straight. Spirulina converts carbon dioxide gas into pure oxygen and the different cell structures stimulate different responses in oxygen production and cultivation. In these experiments, 2.3 L containers of pure coiled spirulina and mixed (coiled and straight) spirulina were placed into 3 incubators with different light intensities: 51µmol/m2/s, 25µmol/m2/s, 12µmol/m2/s. Each experiment length was 72 hours and the …
Investigating Differences In Iga Antibody Response Against Aspergillus Fumigatus In Wild Type And Tlr7 Protein Deficient Mice, Courtney Folk
Investigating Differences In Iga Antibody Response Against Aspergillus Fumigatus In Wild Type And Tlr7 Protein Deficient Mice, Courtney Folk
Student Academic Conference
Aspergillus fumigatus is a commonly inhaled, respiratory fungal pathogen and an allergen found in flooded indoor environments, household dust, soil, and plant matter. While a competent immune system effectively clears the inhaled fungus, this same fungus poses a significant threat to weakened immune systems due to its potential to invade the lungs, bloodstream and brain tissue. The mouse genome is 99% similar to the human genome and can serve effectively model the effects of inhaled A. fumigatus (Guénet, 2005). Antibodies play a crucial role in neutralizing pathogens and in mediating an allergic response. In this study, we will investigate the …

The Effects Of Prenatal Cannabis Exposure On The Basolateral Amygdala, Karen Kw Wong
The Effects Of Prenatal Cannabis Exposure On The Basolateral Amygdala, Karen Kw Wong
Undergraduate Student Research Internships Conference
Clinical and preclinical studies indicate prenatal cannabis exposure (PCE) pathologically affects fetal brain development and may increase vulnerability to neuropsychiatric disorders, including schizophrenia and mood/anxiety disorders. In review research from our lab suggests that fetal exposure to Δ9-THC sex-selectively impairs mesocorticolimbic (MCL) circuit function. However, there is a distinct lack of focus on PCE models on the BLA. The BLA plays a central role within the MCL where it directly interacts with the VTA, PFC and HIPP. Importantly, our model exhibits significant VTA hyperdopaminergic activity, and sex-specific alterations to PFC/HIPP glutamate firing, alongside region- and sex-specific changes in dopamine (DA), …

Undergraduate Student Research Internships Conference
Fibrosis is a progressive and typically irreversible disease process characterized by the excessive deposition of collagen in organs and in tissues of the musculoskeletal (MSK) system1,2. This process, which causes loss of organ and tissue function, can be initiated by micro-traumas3, an excessive and/or prolonged immune response1, the activation and proliferation of fibrosis-inducing progenitor cells4, and a pro-fibrotic extra-cellular microenvironment5. In parallel with the events that initiate fibrosis, genetic or environmental influences may cause cells and tissues to become predisposed to fibrosis development prior to initiation. This suggests that these …

Overtreatment and overuse of antibiotics in healthcare and agricultural settings have contributed to the selective pressure on bacterial strains to develop resistance. Resistance can develop as a result of mutations and subsequent resistance genes that allow bacteria to survive against antibiotics. Novel silver-oxide coatings were developed and were previously demonstrated to prevent adhesion of gram-negative bacteria (Escherichia Coli and Pseudomonas Aeruginosa) to the disc, but did not prevent gram-positive bacterial adherence (Streptococcus Aureus). In order to determine whether the silver-oxide coatings are bacterial static and may be preventing progression to biofilm formation, in vivo analysis of S. Aureus attached to …

Investigating Alternative Induction Of The S. Aureus 80a Prophage, Jody Caretti
Student Scholar Showcase
Widespread antibiotic resistance has quickly become one of the most concerning crises affecting modern medicine, especially in cases of Staphylococcal infections, which have become resistant to all ��-lactam antibiotics. As a result, research into alternative forms of treatment for bacterial infections is a top priority. Bacteriophage therapy is a popular candidate for replacing antibiotics, due to the way the viruses interact with the bacteria. The 80�� prophage integrates its DNA into Staphylococcus aureus strain 10616 via the lysogenic cycle, and replicates with the bacterial cell. When stressed, the bacteria stop replicating and the prophage stimulates the lytic cycle, activating transcription …
