Coliphage T3 S-adenosylmethionine hydrolase : properties of the cloned gene and consequences of its expression in Escherichia coli

Creator:: Hughes, Jeffrey A.
Abstract:: To begin the development of a research tool for use in the in vivo study of S-adenosylmethionine (SAM) metabolism, I attempted to locate, isolate, clone and elicit the expression of the SAM hydrolase gene (E.C. 3.3.1.2) of the coliphage T3. The gene was isolated and cloned into the M13mp8 cloning...

Structural analysis of thermally inactivated nisin

Creator:: Musafija-Jeknic, Tamara
Abstract:: Nisin, an antimicrobial peptide used in food preservation was evaluated for thermal stability. Nisin retained antimicrobial activity after having been heated at 121°C for seven hours. Anhydrous nisin and concentrated nisin solutions (5-10 mg/ml) were still active after having been heated up to 190°C or 230°C. When exposed to high...

Biotransformation of 2,4,6-trinitrotoluene by ruminal organisms

Creator:: De Lorme, Marthah J. M.
Abstract:: 2,4,6-Trinitrotoluene (TNT) has been the common munitions used in the world and is an environmental contaminant that is amendable to reductive transformation reactions. The rumen is an extremely reductive environment containing diverse microbial populations. There are 21 pure culture ruminal bacteria species in culture collection, these were tested for the...

Bacteriophages for Leuconostoc oenos : a survey of Oregon wineries

Creator:: Eschelbach, Matthew Michael
Abstract:: A study of malolactic bacteria of the Leuconostoc genus, especially L. oenos, and their bacteriophages was conducted. A search for the presence of infectious bacteriophages in grapes, musts, and juices employed in malo-lactic fermentation (MLF) was conducted; no evidence, either physical or biological, was found for the existence of these...

Impacts of Environmental Change on a Newly-characterized Symbiosis between a Novel Bacterial Parasite, Genus Aquarickettsia, and the Coral Acropora cervicornis

Creator:: Klinges, J. Grace
Abstract:: Coral reef ecosystems continue to be significantly altered by disease epizootics, but why some host populations remain resistant while others succumb to outbreaks remains unknown. Research across diverse animal and plant host systems has revealed that disease severity is strongly influenced by host genetics and by environmental influences on both...

Chromosomal Recombination Targets in Chlamydial Lateral Gene Transfer In Vitro

Creator:: Kim, Debbie Blue
Abstract:: Background: Lateral gene transfer (LGT) among C. trachomatis strains is common, both in isolates generated in the laboratory and those examined directly from patients. This is a challenging concept because there are very few examples of recent acquisition of foreign DNA by Chlamydia spp. There is no understanding of the...

Herbicide effects on Bdellovibrio bacteriovorus

Creator:: Wehr, Nancy Briggs
Abstract:: Bdellovibrio bacteriovorus is a small parasitic bacterium present in soil, mud, and aquatic habitats. Due to its lysis of Gramnegative bacteria, an important role in soil ecology has been suggested for this organism. A study of effects of herbicides upon Bdellovibrio might consequently be of considerable value. In this study...

Exploring new avenues of public education, diagnosis and treatment for traumatic brain injury: compiling professional opinions

Creator:: Nowlin, Taylor M.
Abstract:: Affecting an estimated 1.7 million people annually, traumatic brain injury has been labeled a major public health threat. As the leading cause of death and disability in young people, and the signature wound of the wars in Iraq and Afghanistan, the issue is drawing increased media attention. Analyses begin by...

The regulation of a vaccinia virus late gene required for morphogenesis

Creator:: Miner, Jeffery N.
Abstract:: Vaccinia virus gene expression is characterized by tight temporal regulation. Viral early transcription begins within the cytoplasm upon infection; three hours later, early genes are repressed, DNA replication occurs and late gene expression commences. As an approach toward understanding the mechanisms governing vaccinia late gene expression, I have undertaken an...

Characterization of Mycobacterium avium subsp. hominissuis Interactions with Host Macrophages and Multinucleated Giant Cells

Creator:: Joseph, Jayanthi J.
Abstract:: To examine the macrophage response to M. avium, I compared inflammasome and cytosolic sensor expression and activation. My result demonstrated that virulent strains of M. avium (A5 and 104) suppress IL-1β production and induce IFN-β production in macrophages. M. avium mutants deficient at DNA export in the biofilm exhibited reduced...
