Antimicrobial resistance and plasmid properties of Leuconostoc and group N Streptococcus

Creator:: Orberg, Paulo K.
Abstract:: A method for rapid isolation of plasmid DNA from group N streptococci was developed. Chief advantages of the method were simplicity, the utilization of microliter quantities of reagents, and the obtainment of preparations highly enriched for covalently closed circular plasmid DNA. The method was also applied to over 15 Leuconostoc...

The isolation, comparison, and attenuation of several viruses infecting Oregon salmonids

Creator:: McMichael, John Seiple
Abstract:: The Oregon strain of the agent of infectious hematopoietic necrosis (IHN) was isolated from fingerling sockeye salmon (Oncorhynchus nerka) by J. L. Fryer in 1958. Before the study reported herein no other virus had been recovered from any fish population in Oregon. Therefore, in July, 1971 a survey was initiated...

Poliovirus adsorption by soil particles in seawater

Creator:: Jakubowski, W. (Walter)
Abstract:: This investigation was initiated in an attempt to delineate some factors affecting the adsorption of poliovirus to soil particles in seawater. The results could have significance in the development of assay procedures for viral contaminants in natural waters. A sample of marine sediment, obtained from an estuary near Purdy, Washington,...

Virulence factors of Aeromonas salmonicida and their interaction with the salmonid host

Creator:: Rockey, Daniel D.
Abstract:: Selected secreted and cellular virulence factors of Aeromonas salmonicida were examined. A protocol was developed for the separation of two secreted proteases (P1 and P2 protease), and a trout erythrocyte specific hemolysin (T-lysin) from supernatants of cultures of the bacterium. Distinctions between the proteases were demonstrated using molecular weight determinations,...

Viruses infecting salmonid fishes from Oregon : A. The occurrence and distribution of infectious pancreatic necrosis virus. B. The development of an attenuated strain of infectious hematopoietic necrosis virus (IHNV) for immunization of salmonids

Creator:: Tebbit, Guy Lee
Abstract:: The occurrence and distribution of fish viruses in Oregon were determined by the examination of anadromous and fresh water salmonids. Infectious pancreatic necrosis virus (IPNV) was isolated and identified from asymptomatic adult coho (Oncorhynchus kisutch) and chinook (0. tshawytscha) salmon returning to the Columbia River system. Infectious pancreatic necrosis virus...

Certain chemical and immunological properties of the endotoxin from Vibrio anguillarum

Creator:: Abe, Patrick Masami
Abstract:: The Boivin agent from Vibrio anguillarum was extracted with the use of 0.25M trichloroacetic acid (TCA). Chemical analysis revealed that the endotoxin contained approximately 35.1% protein, 18.1% carbohydrate, 39.3% lipid, 1.8% glucosamine and evidence of ethanolamine. Sixteen different amino acids made up the protein. The aliphatic amino acid concentration was...

Susceptibility of two salmonid fish cell lines to two viruses from fish and two from homothermic animals

Creator:: Nims, Linda Jean
Abstract:: This thesis describes the viral susceptibility of two cell cultures established from embryonic tissue of salmonid fish, chinook salmon line CHSE-114 and steelhead trout line STE-137. The viruses used were Oregon sockeye salmon virus (OSV), Sacramento River chinook disease virus (SRCD), Western equine encephalitis virus (WEE) and Newcastle disease virus...

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...

Marine bacterioplankton abundances and distributions

Creator:: Morris, Robert M.
Abstract:: Microorganisms play key roles in ocean biogeochemistry. However, several predominant groups of uncultured bacterioplankton thought to contribute to important biogeochemical processes in the oceans are known primarily from gene cloning studies. Although these studies have greatly expanded our view of microbial diversity in the oceans, they are not quantitative and...

Re-examining Ceratomyxa shasta in the Pacific Northwest

Creator:: Stinson, Matthew E. T.
Abstract:: Ceratomyxa shasta infects salmonids in the Pacific Northwest (PNW) of North America, occasionally causing losses in wild and captive populations. Host-specific parasite genotypes (O, I, II, III) were previously characterized molecularly using markers in the ribosomal DNA and phenotypically by type host in the Klamath River, CA/OR. This thesis sough...
