Type 2 Bovine Viral Diarrhea Virus NPro Suppresses Type I Interferon Pathway Signaling In Bovine Cells And Augments Bovine Respiratory Syncytial Virus Replication, Abdulrahman Abdulaziz A. Alkheraif

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

Bovine viral diarrhea virus (BVDV) and bovine respiratory syncytial virus (BRSV) infections contribute to the bovine respiratory disease complex (BRDC), which is a multi-factorial disorder involving co-infections of viruses and bacteria including mycoplasma. BRDC causes great economic losses to the United States feedlot industry. BVDV infection induces immunosuppression in infected animals. BVDV N^pro binds and degrades the transcription factor interferon regulatory factor-3 (IRF-3) and effectively blocks type I interferon (type I IFN) expression in host cells. BRSV nonstructural proteins, NS1 and NS2, block activation of IRF-3. In calves, concurrent infection with BVDV and BRSV resulted in more severe clinical …

Plastics And Microplastics As Vectors For Bacteria And Human Pathogens, Amanda Lee Laverty

OES Theses and Dissertations

Since plastics degrade very slowly, they remain in the environment on much longer timescales than most natural substrates and can thus provide a novel habitat for colonization by bacterial communities. The full spectrum of relationships between plastics and bacteria, however, is little understood. The objective of this study was to examine marine plastic pollution as a substrate for bacteria, with particular focus on Vibrio spp., including the human pathogens, Vibrio cholerae, Vibrio parahaemolyticus, and Vibrio vulnificus.

Colonization experiments were set up in a tributary of the lower Chesapeake Bay to follow Vibrio spp. colonization and …

Schistosomiasis As A Cause Of Acute Cholecystitis, Shaker A. Majrashi

Saudi Medical Journal

Schistosomal cholecystitis is remarkably uncommon disease which is associated with concomitant gallstone disease. The disease prevails with low socio-economic conditions of population. It is still not clear that the widespread fibrocalcific reaction in the wall of gallbladder and the cystic duct, observed for all the reports, predisposes to cholelithiasis or gallstones coexist. In the present study, we report a case of the Saudi male patient affected with schistosomal granulomatous lithiasic cholecystitis. The patient’s gallbladder was badly inflamed therefore performing a safe cholecystectomy in the patient was extremely difficult.

Characterization of Metronidazole- and Vancomycin-Resistant Clinical Isolates of Clostridium difficile

Chioma Odo, MS.

Supervisory Professor: Charles Darkoh, Ph.D.

ABSTRACT

The incidence of C. difficile infections (CDI) has been increasing at an alarming rate. This was precipitated by the emergence of strains with increased virulence, disease severity, and high recurrence rates. These strains also exhibit high propensity for resistance to antibiotics such as fluoroquinolones and beta lactams, which has made the treatment of CDI very challenging. Currently, metronidazole and vancomycin are the most commonly used drugs for the treatment of primary CDI. Metronidazole is used for the treatment of mild to …

Genetic Basis For Elevated Rheumatic Heart Disease Susceptibility In Samoa, John Bowen Allen

Theses and Dissertations

Rheumatic heart disease is an inflammatory heart disease that affects millions of people around the world. Especially high rates of the disease can be found in Oceania, including the island nation of Samoa. Genetic studies of immune response genes have provided insight into a possible genetic link to increased susceptibility to rheumatic heart disease, including the genes that code for the toll-like receptor (TLR) protein family. One of the functions of TLR proteins is to recognize the presence of bacteria via identification of bacterial flagella. My evaluation of a Samoan family identified a variant in the TLR-5 gene that would …

The Ability Of Novel Phage To Infect Virulent Bacillus Anthracis Isolates, Hyrum Smith Shumway

Theses and Dissertations

Bacillus anthracis is a soil dwelling microbe with pronounced pathogenic potential. Historically, anthrax has infected livestock and man. In the modern-age, anthrax is a bioterrorism concern with major incidents every decade. While the threat of large scale attacks is currently viewed as unlikely, the threat is consistent and constant. Current methods to defend against such an attack focus on antibiotics and containment of public panic. Antibiotic resistance, while not currently an issue for anthrax, could easily become so with genetically engineered weaponized strains created by rogue states or independent actors. This project evolved from collaborations between the Grose lab and …

Characterizing The Activity Of Antimicrobial Peptides Against The Pathogenic Bacterium Clostridium Difficile In An Anaerobic Environment, Adenrele Mojeed Oludiran

Chemistry & Biochemistry Theses & Dissertations

Clostridium difficile is an anaerobic Gram-positive pathogen with high treatment costs and mortality and very high antibiotic tolerance. Antimicrobial host-defense peptides (HDPs) produced naturally by animal immune systems are promising candidates to develop novel therapies for bacterial infection because they cause oxidative stress that damages multiple targets in bacterial cells, so it is difficult for bacteria to evolve resistance to these attacks.

Piscidins, fish-derived HDPs that can also form complexes with copper (Cu) to enhance their activities, are very active against multiple bacterial species in an aerobic environment. We examined their activity against C. difficile and other species in an …

Endocannabinoid Metabolome Of Human Breast Milk, Adriana V. Gaitan Espinoza

LSU Doctoral Dissertations

Human breast milk (HBM) is an extremely complex yet fascinating biofluid tailored to meet an infant’s nutritional requirements for development. Amongst the nutrients present in HBM, the long-chain polyunsaturated fatty acids (LCPUFAs) are of high importance due to the pivotal role they play in infant cognitive and visual development, and growth. In addition, the LCPUFAs are precursors to endocannabinoids (EC) which are endogenous lipid mediators. EC exert metabolic responses including appetite and food intake regulation, and they have been identified to play a role in establishing the suckling response of the newborn that is needed to nurse. Thus, we aimed …

Oral Health Related Quality Of Life, Dental Care Utilization, And Serostatus Disclosure Among Hiv-Positive Women In The Women’S Interagency Hiv Study (Wihs) Cohort, Carrigan Parish

Open Access Dissertations

Persons living with HIV are more likely than HIV-negative individuals to experience oral health problems, yet are also more likely to have unmet dental care treatment needs. Dental needs among HIV-positive individuals can also be more severe and difficult to manage compared to the general population, often contributing to the onset of opportunistic oral infections. Furthermore, dental problems in patients with HIV can be associated with low CD4 counts and poor immune function. Due to the underutilization of dental services, oral health problems and symptoms, especially those that are related to HIV infection, remain prevalent in this population. Neglected dental …
