Host range and chemical composition of lactic streptococcal bacteriophages

Creator:: Henning, David Ralph
Abstract:: Comparisons were made of the abilities of Streptococcus lactis, Streptococcus cremoris and Streptococcus diacetilactis bacteriophages to endure various laboratory isolation and storage treatments. Neutralization of Cottage cheese whey containing phages offered no survival advantage over unneutralized samples, refrigeration of neutral and acid whey samples increased the survival of only the...

Physical and functional characterization of soluble protein antigen(s) produced by Renibacterium salmoninarum

Creator:: Turaga, Prasad S. D.
Abstract:: Renibacterium salmoninarum produces bacterial kidney disease (BKD) in salmonid fish. Soluble antigen(s) (SA) produced by the bacterium was characterized by physicochemical, functional and immunological methods. The molecular weight determination by SDS-PAGE analysis of SA yielded 14 different molecular weight species. Seven of these species were prominent, 57 kd protein being...

Investigating Vibrio parahaemolyticus interactions with the Pacific oyster, Crassostrea gigas

Creator:: Aagesen, Alisha M.
Abstract:: Vibrio parahaemolyticus is a Gram-negative, halophilic, human pathogenic bacterium ubiquitous in the marine environment. Like many Vibrio species, V. parahaemolyticus commonly associates with shellfish, particularly oysters. Ingestion of a raw or under cooked oysters contaminated with V. parahaemolyticus can cause gastroenteritis, which is typically self-limiting and rarely causes death. Globally,...

Comparative Genomics of Freshwater Bloom-Forming Cyanobacteria and Associated Organisms

Creator:: Driscoll, Connor B.
Abstract:: The advent of improved DNA sequencing technologies has allowed the analysis of various microbial communities. Bloom-forming freshwater cyanobacteria can produce toxins and taste-and-odor compounds that can negatively affect drinking water supplies. Here, I have employed second- and third-generation sequencing technologies to characterize bloom-forming freshwater cyanobacterial genomes and their associated heterotrophic...

Delineation of the composition of an indigenous soil population of Rhizobium meliloti in root nodules of uninoculated field grown Medicago sativa L.

Creator:: Jenkins, Michael B.
Abstract:: Agronomic and microbiological studies were conducted on "Anchor" alfalfa (Medicago sativa L.) established from uninoculated seed on three Aridisols in central Oregon. Significant responses to 230 Kg N per ha (NH₄NO₃), which was applied in mid-April and after each first and second harvests, were observed in yield parameters of the...

Studies on host range, fine structure, and nucleic acids of lactic streptococcus bacteriophages

Creator:: Nyiendo, Joanne Annette
Abstract:: The most frequent cause of insufficient acid production during fermentation of dairy products is bacteriophage infection of lactic starter cultures. Previously, efforts to minimize this problem have dealt primarily with the host range relationships of the viruses and susceptibility patterns of the lactic streptococci. This study was undertaken to characterize...

Secreted Agrobacterium rhizogenes Effector Protein GALLS Interacts with Arabidopsis Host Proteins and Stimulates Agrobacterium-mediated Transformation

Creator:: Wei, Wei
Abstract:: Agrobacterium species transform plant cells by targeting a portion of plasmid-encoded bacterial DNA to the host nucleus. Genetic transformation by A. tumefaciens and A. rhizogenes requires secreted effector proteins. The tumor-inducing (Ti) plasmid from virulent A. tumefaciens encodes VirE2, a secreted single-stranded DNA-binding protein required for efficient transformation of hosts....

Preventing crown gall disease using oncogene silencing or VirE1-expressing transgenics

Creator:: Humann, Jodi L.
Abstract:: Crown gall disease is caused by the ubiquitous soil bacterium Agrobacterium tumefaciens which transfers a portion if DNA (T-DNA) into the plant cell. Preventing infection by using the biocontrol strain Agrobacterium radiobacter K84 is currently the only defense for crown gall. Two different resistance strategies were examined in this work....

Coordinated regulation of plasma membrane lipids in Saccharomyces cerevisiae

Creator:: Low, Christopher S. F.
Abstract:: Plasma membranes isolated from a yeast sterol auxotroph (RD5-R) grown on 1,5, and 15 pg m1⁻¹ exogenous concentrations of sterol showed no discontinuity in plots of steady-state fluorescence anisotropy. Liposomes constructed from phospholipid and sterol extracted from RD5-R grown on different sterols indicated exogenously supplied sterol modulated cellular phospholipids such...
