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...

A study of Myxobolus cerebralis in the Lostine River, Oregon : epizootiology, distribution and implications for resident and anadromous salmonids

Creator:: Sandell, Todd A.
Abstract:: Myxobolus cerebralis, a myxozoan parasite that infects almost all species of wild and cultured salmonids, was first identified in northeastern Oregon in the Lostine River in 1986. Fish that are heavily infected with M. cerebralis develop whirling disease, which was determined to be the cause of catastrophic declines in rainbow...

Development of mucosal vaccines for avian influenza A virus composed of recombinant Lactococcus lactis and Streptococcus gordonii

Creator:: Reese, Kaleb A.
Abstract:: Novel mucosal vaccines (LL-M2e, LL-HAe, SG-HAe) were constructed from live, non-pathogenic Lactococcus lactis or Streptococcus gordonii that express conserved regions of HA or M2 antigens from avian influenza virus (AIV) A. All three vaccines evoked antigen-specific serum immunoglobulin G (IgG) responses in vaccinated chickens. The addition of the adjuvant cholera...

Expanding Diagnostic Assays for Pseudoloma neurophilia & Description of the Progression of Infection in Adult Zebrafish Populations

Creator:: Schuster, Corbin J.
Abstract:: Pseudoloma neurophilia is the most common pathogen reported in zebrafish (Danio rerio) research facilities and is an important threat to the zebrafish model. This microsporidian parasite can cause clinical disease, but more importantly is a causative agent of non-protocol induced variation in research. Studies utilizing infected zebrafish, could potentially confound...

Harnessing Heterogeneity in Human Gut Microbiome Data

Creator:: Tataru, Christine
Abstract:: The focus of this thesis is to design, characterize, and apply novel computational methods and molecular systems to interrogate heterogeneous human gut microbiome-related phenomena. In Chapter 2, I design, implement, and characterize a method for embedding co-occurrence patterns derived from massive 16s amplicon datasets. I use this method to 1....

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...

Structural effects on Arthrobacter ATCC 25581 methylene hydroxylase activity

Creator:: Hayasaka, Steven Shin
Abstract:: Arthrobacter ATCC 25581, capable of subterminal oxidation of n-hexadecane to 2-, 3-, and 4- alcoholic and ketonic products, was examined for the ability of this methylene hydroxylase capability to be induced and repressed, and for structural relationships influencing methylene function oxidation. Induction was best carried out by use of n-alkanes...

Ruminal Biodegradation of Heterocyclic Toxic Compounds

Creator:: Tanaree, Dan D.
Abstract:: Cyclic nitramines are a class of compounds that include most of the commonly used explosives today. These are among the most common toxicants released into the environment as a result of human activity, generated on military ranges, battlefields, and production sites. Of these, hexahydro-1,3,5-trinitro-1,3,5- triazine (RDX) is of particular interest,...

Molecular characterization of bacterial populations implicated inthe anaerobic metabolism of toxic plant alkaloids from two different experimental and environmental sources

Creator:: Rattray, Rogan MacKay
Abstract:: There have been many studies that describe the protective degradation or metabolism of potentially harmful plant toxins, such as, mimosine from Leucaena leuconcephala, pyrrolizidine alkaloids from tansy ragwort (Senecio jacobaea), oxalate and some mycotoxins by rumen microbes. There are many cases of plant-related toxicoses suffered by ruminant animals where there...
