Terminal methylation reactions in Saccharomyces cerevisiae

Creator:: Botsford, James Lawrence
Abstract:: A cell-free system for assessing the role of S-adenosyl-methionine in the methylation of homocysteine deriving the methyl group from serine has been developed. No role for S-adenosyl-methionine could be shown in the in vitro reaction The enzyme serine transhydroxymethylase has been studied in crude and partially purified cell extracts. Evidence...

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...

Visualizing Rivers: An Interactive Map of United States Water Sheds

Creator:: Burk, Bailey K.
Abstract:: An interactive map of important watersheds in the United States was created for use as a teaching tool in an estuarine ecology class. Figures and explanations of important factors influencing river ecology were created using data downloaded from the U.S. Geologic Survey. This interface serves as a visualization of biological,...

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...

Characterization of an inhibitor ("6S") of infectious pancreatic necrosis virus (IPNV) in normal rainbow trout serum (RTS) and its effects on the virus

Creator:: Park, Kyoung Chul
Abstract:: The characteristics of an inhibitor of infectious pancreatic necrosis virus (IPNV) found in normal rainbow trout serum (RTS) were studied. The serum inhibitor had a molecular weight of approximately 150 kDa and was dependent on divalent cations, either Ca²⁺ or Mg²⁺. It was stable at temperatures up to 50°C and...

Epitope mapping and characterization of the glycoprotein of infectious hematopoietic necrosis virus

Creator:: Xu, Li
Abstract:: A characterization of the antigenic determinants (epitopes) of the glycoprotein (G) of infectious hematopoietic necrosis virus (IHNV) was made with different regions of the G gene expressed in Escherichia coli. A cDNA copy of the G gene was divided into four fragments after Taq I digestion and these fragments were...

Pseudoloma neurophilia : progression of infection and transmission characteristics of a microsporidian parasite in a model vertebrate, Danio rerio

Creator:: Sanders, Justin L.
Abstract:: The microsporidian parasite, Pseudoloma neurophilia, is the most commonly diagnosed infectious disease in laboratory populations of the zebrafish, Danio rerio. Infections by P. neurophilia are generally subclinical, however, they can become acute either incidentally or due to experimental immune suppression. Non-protocol induced variation can confound results in laboratory experiments using...

Impacts of Environmental Change on a Newly-characterized Symbiosis between a Novel Bacterial Parasite, Genus Aquarickettsia, and the Coral Acropora cervicornis

Creator:: Klinges, J. Grace
Abstract:: Coral reef ecosystems continue to be significantly altered by disease epizootics, but why some host populations remain resistant while others succumb to outbreaks remains unknown. Research across diverse animal and plant host systems has revealed that disease severity is strongly influenced by host genetics and by environmental influences on both...

Intestinal Lesions and Parasites Associated with Senescence and Prespawn Mortality in Chinook Salmon (Oncorhynchus tshawytscha)

Creator:: Nervino, Stephanie A.
Abstract:: Pre-spawning mortality (PSM) presents a major problem for population recovery of spring Chinook salmon (Oncorhynchus tshawytscha) in the Willamette River basin. In certain reaches and years, PSM has exceeded 90%. Histology has been used as the primary diagnostic method to investigate PSM in the Chinook Salmon, and a collection of...

Analysis of Betta splendens erythrophore responses to Bacillus cereus cultured in different media

Creator:: Austin, Melissa J.
Abstract:: Biological agents and their products commonly cause foodborne illnesses. In the United States it is estimated that there are over 76 million cases of foodborne illnesses each year, resulting in an economic loss of approximately $40 billion. These high figures demonstrate the need for bioassays that display a rapid and...
