Chlamydiae under stress : environmental conditions influence the production and localization of chlamydial antigens

Creator:: Brown, Wendy J.
Abstract:: Chlamydiae are obligate intracellular pathogens that cause several serious conditions within the human host. Many of the symptoms associated with infection are thought to stem from the development of aberrant, or persistent, chlamydiae. Factors leading to chlamydial persistence include deprivation of amino acids, the release of certain cellular factors, or...

Genetic variation of chlamydial Inc proteins

Creator:: Viratyosin, Wasna
Abstract:: Genomic analysis is a new approach for the characterization and investigation of novel genes, gene clusters, the function of uncharacterized proteins, and genetic diversity in microorganisms. These approaches are important for the study of chlamydiae, a system in which several genomes have been sequenced but in which techniques for genetic...

Final report : environmental stresses and skeletal deformities in fish from the Willamette River, Oregon, USA

Creator:: Villeneuve, Daniel L., Curtis, Lawrence R., Jenkins, Jeffrey J., Warner, Kara E., Tilton, Fred A., Kent, Michael L., Watral, Virginia G., Cunningham, Michael E., Markle, Douglas F., Sethajintanin, Doolalai, Krissanakriangkrai, Oraphin, Johnson, Eugene R., Grove, Robert Allan, Anderson, Kim A., Oregon State University. Department of Microbiology, Oregon State University. Department of Environmental and Molecular Toxicology, Oregon State University. Department of Fisheries and Wildlife, and Institute for Natural Resources
Abstract:: The Willamette River, one of only 14 American Heritage Rivers, flows through the most densely populated and agriculturally productive region of Oregon. Previous biological monitoring of Willamette River fish detected elevated frequencies of skeletal deformities in fish from certain areas of the lower (NP [NP], rivermile [RM] 26-55) and middle...

The Deep Sea and Me : using a science center exhibit to promote lasting public literacy and elucidate public perception of the deep sea

Creator:: Darr, Katherine D., East, Jennifer L., Seabrook, Sarah, Dundas, Steven J., and Thurber, Andrew R.
Abstract:: A critical barrier to effective management of deep-sea resources is a lack of understanding by society of the benefits received from the oceans. To address this knowledge gap, we applied an iterative design-based research methodology to evaluate (1) how to effectively use an exhibit to increase public literacy of the...

Consequences of Influenza A Virus on Pneumococcal Biofilm Formation and Stability in the Absence of Host Factors

Creator:: Nutter, Laura
Abstract:: Streptococcus pneumoniae and Influenza A Virus both primarily infect the upper respiratory tract, with more severe disease occurring during coinfection than would be caused by either pathogen independently. Until recently, characterization of the interactions between these two pathogens has occurred exclusively in the context of a host or using host-derived...

Hydraulic predictors and seasonal distribution of Manayunkia speciosa density in the Klamath River, CA, with implications for ceratomyxosis, a disease of salmon and trout

Creator:: Jordan, Michelle S.
Abstract:: The freshwater polychaete Manayunkia speciosa was identified as an obligate host of the salmonid parasite Ceratomyxa shasta in 1997, prompting increased research on the small benthic invertebrate. Ceratomyxa shasta infection in fish can cause mortality, and presents a disease risk for both hatchery and wild salmon and trout. Ceratomyxa shasta...

Testing monotonic trends among multiple group means against a composite null

Creator:: Hu, Chenxiao, Sharpton, Thomas, and Jiang, Duo
Abstract:: In biomedical applications, it is often of interest to test the alternative hypothesis that the means of three or more groups follow a strictly monotonic trend such as u1 > u2 > u3 against the null hypothesis that the group means are either equal or unequal but are not monotonic....

Analysis of segregants of F'gal heterogenotes in Escherichia coli

Creator:: Kurahara, Carole Mahaney
Abstract:: The purpose of this study was to isolate and characterize any segregants of the heterogenotes formed from sexduction by an F' donor. Following the mating of F' W4520, carrying an F' gal₁⁺ gal₂⁺ factor, with W3350, a gal₁⁻ gal₂⁻ recipient, a number of recombinant clones were picked and examined for...

The role of chlamydial inclusion membrane proteins in host-pathogen interaction and the development of novel methods for studying chlamydial biology

Creator:: Alzhanov, Damir T.
Abstract:: The majority of our modern understanding of bacterial pathogenesis is based on the strategy that involves screening bacterial genomes for the presence of the genes encoding pathogenic factors, and analysis of these genes via forward and reverse genetics. Chlamydiae represent a unique group of pathogenic bacteria in which it is...

The exploitation of methylthioadenosine phosphorylase deficiency in cancer therapy

Creator:: Lindburg, Katherine L.
Abstract:: Methylthioadenosine (MTA) is a naturally occuring nucleoside formed during the synthesis of polyamines in mammalian cells. MTA is rapidly catabolised by MTA phosphorylase (MTAase), eventually yielding methionine and adenine. MTAase has been shown to be active in all normal cells, but deficient in some cells and tissues of malignant origin....
