Impacts of microbial chemical interactions on marine plankton physiology

Creator:: Moore, Eric R.
Abstract:: The bioavailability of chemical compounds in the marine environment fundamentally influences the growth and physiology of microorganisms. Organic and inorganic chemicals that are produced by some marine plankton can be consumed by other plankton for energy production, growth, or to initiate essential physiological processes. Cultures of the diatom Thalassiosira pseudonana,...

Determination of differential gene action in Bdellovibrio bacteriovorus using RNA-DNA hybridization techniques

Creator:: Reed, Margaret Ann
Abstract:: In an attempt to study the times in the lifecycle of Bdellovibrio bacteriovorus at which various genes are transcribed, the patterns of messenger ribonucleic acid (mRNA) and ribosomal ribonucleic acid (rRNA) syntheses were examined using two different types of hybridization systems. The hybridization system using membrane bound deoxyribonucleic acid (DNA)...

Occurrence of the protozoan fish parasite Ceratomyxa shasta in the Deschutes River basin and the ultrastructure of the spore

Creator:: Gould, Rowan Wayne
Abstract:: The purpose of this paper was twofold, (1) to determine the distribution of the infective stage of Ceratomyxa shasta (Noble) in the Deschutes River basin, and (2) to study the ultrastructure of the spore stage of the protozoan parasite. Liveboxes containing juvenile rainbow trout were placed at specific test points...

Chromatophores as cell-based biosensors for the detection of chemically and biologically toxic substances

Creator:: Dukovcic, Stephanie R.
Abstract:: Cell-based biosensors are function-based detectors that use the physiological response of a living cell to sense biologically stimulating agents. This emerging technology extends the application of current detection methods by reporting on the toxicity of a sample and the potential to cause disease. Previously, Betta splendens erythrophores have been described...

Ceratomyxa shasta-related concerns for reintroduced anadromous salmonids into the Upper Klamath Basin, CA-OR, USA

Creator:: Hurst, Charlene N.
Abstract:: The myxozoan parasite of salmonids, Ceratomyxa shasta, is established throughout the Klamath River, CA-OR, with high parasite densities below the series of dams and above the dams (upper basin) in the northernmost tributary, the Williamson River (WMR). Two objectives were designed to address concerns about C. shasta effects on reintroduced...

An investigation of carbon and nitrogen metabolism through a genomic analysis of the genus Nitrobacter

Creator:: Starkenburg, Shawn R.
Abstract:: The chemolithoautotrophic nitrite oxidizing bacteria (NOB) participate in the biogeochemical cycling of nitrogen by catalyzing and conserving energy from the oxidation of nitrite (NO₂-) to nitrate (NO₃-) via a nitrite oxidoreductase (NXR). The main objective of this work was to comparatively annotate and analyze the genome sequences of Nitrobacter winogradskyi...

Recombinant vaccines against infectious hematopoietic necrosis virus : bacterial systems for vaccine production and delivery

Creator:: Simon, Benjamin E.
Abstract:: Several systems were examined for the production and delivery of recombinant vaccines for fish. C. crescentus was employed to produce a fragment of the IHNV glycoprotein. When administered by injection to 0.5 gram rainbow trout (Oncorhynchus mykiss), one of the fusion proteins (184 amino acids of the IHNV glycoprotein fused...

The effects of single and multiple pathogen and parasite infections on juvenile chinook and coho salmon during early marine residency

Creator:: Sandell, Todd A.
Abstract:: Nearly 3000 juvenile Chinook (Oncorhynchus tshawytscha) and coho (O. kisutch) salmon captured in nearshore waters off the coasts of Washington and Oregon from 1999-2004 were tested for infection by Renibacterium salmoninarum, Nanophyetus salmincola, and skin metacercariae. First, three quantitative PCR primer/probe sets were compared for detection of R. salmoninarum; amplification...

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...

Characterization of microaggregate formation by Mycobacterium avium subspecies hominissuis

Creator:: Babrak, Lmar
Abstract:: Mycobacterium avium subsp hominissuis (MAH) is an opportunistic environmental pathogen that causes respiratory and gastrointestinal illness in immunocompromised persons such as those with chronic respiratory diseases or AIDs, respectively. In recent years, there has been a significant increase in the incidence of nontuberculous mycobacterial (NTM) lung infections, including in cystic...
