The simultaneous expression of metal tolerance and antibiotic resistance by bacteria from drinking water systems

Creator:: Calomiris, Jon James
Abstract:: Previous studies of six Oregon public water supply systems revealed that greater proportions of the standard plate count (SPC) bacteria from distribution waters were multiple antibiotic resistant (MAR) compared to isolates from the corresponding source raw waters. In the present study, two of these water systems were examined further to...

Microbial diversity, metabolic potential, and transcriptional activity along the inner continental shelf of the Northeast Pacific Ocean

Creator:: Bertagnolli, Anthony D.
Abstract:: Continental shelves located along eastern boundary currents occupy relatively small volumes of the world’s oceans, yet are responsible for a large proportion of global primary production. The Oregon coast is among these ecosystems. Recent analyses of dissolved oxygen at shallow depths in the water column has suggested increasing episodes of...

Bdellovibrio metabolism of host macromolecules

Creator:: Engelking, Henry Mark
Abstract:: The genus Bdellovibrio is characterized by the unique ability to parasitize and enter gram-negative host bacteria. This interaction leads to the consumption and death of the host cell as the Bdellovibrio grows and divides into progeny. Little is known about the metabolism of host cell components by Bdellovibrio. The possibility...

Conserved properties in the metagenome of a large bacterioplankton population

Creator:: Wilhelm, Larry John
Abstract:: Candidatus Pelagibacter ubique is the first cultured representative of the SAR11 clade, a clade that is found throughout the oceans and accounts for approximately 25% of all bacterial cells [1]. It has a streamlined genome that is the smallest of any known free-living organism. In this study the complete genome...

Oral immunization for possible control of furunculosis in fish

Creator:: Frost, Gary Douglas
Abstract:: This project was initiated in an attempt to control furunculosis (Aeromonas salmonicida) in a production hatchery rearing coho salmon. An oral vaccine was prepared and administered to 520,000 juvenile coho salmon (Oncorhynchus kisutch) at the Siletz River Salmon Hatchery prior to the onset of a predictable naturally occurring epizootic of...

Single-Cell Genomics of Uncultivated Marine Bacteria

Creator:: Landry, Zachary
Abstract:: Historically, the difficulty of obtaining pure cultures of abundant marine microbial plankton has an obstacle to reconstructing the underlying mechanisms of biogeochemistry in the ocean. While a number of dominant marine species from the ocean surface have been cultured, the dominant microbial plankton of the dark ocean proved far more...

Establishment of an in vitro System for Studying Mycobacterium avium Protein Secretion

Creator:: Chinison, Jessica J.
Abstract:: Cases of pulmonary diseases caused by Mycobacterium avium complex (MAC) have increased over the years and have become a major health concern in Europe, Asia, and the United States. MAC, comprised of M. avium species and M. intracellulare, are found everywhere in the environment: in water sources and the soil....

Microbiology of basalts targeted for deep geological carbon sequestration : field observations and laboratory experiments

Creator:: Lavalleur, Heather J.
Abstract:: With rising concentrations of CO₂ in the Earth's atmosphere causing concern about climate change, many solutions are being presented to decrease emissions. One of the proposed solutions is to sequester excess CO₂ in geological formations such as basalt. The deep subsurface is known to harbor much of the microbial biomass...

Chemical and Genetic Investigations of Toxic Freshwater Cyanobacterial Blooms for Improved Monitoring and Understanding of Lake Ecology

Creator:: Collart, Lindsay P.
Abstract:: Toxin production by cyanobacterial harmful algal blooms (cyanoHABs) in freshwater systems has lasting ecological and human impacts. Nutrients, light availability, hydrology, and microbial community composition impact the frequency and intensity of toxic cyanoHABs. Climate change will exacerbate toxic cyanoHABs, making real time and predictive monitoring a vital tool for managing...
