Defining roles for sterols in Saccharomyces cerevisiae : characterization of bulk membrane and high specificity sparking functions

Creator:: Rodriguez, Russell John
Abstract:: The ability of cholestanol to support growth of yeast sterol auxotrophs has been examined. Growth on this stanol was precluded unless minute quantities of ergosterol were available, a phenomenon designated sparking. The low levels of ergosterol were insufficient to support growth alone. The data indicate that cholestanol is fulfilling a...

Fecal Bacteroidetes host distributions and environmental source tracking

Creator:: Dick, Linda K.
Abstract:: Contamination of recreational and shellfish waters with fecal pollution is a major water quality issue with associated economic impacts and human health risks. Reliable fecal source identification and rapid, quantitative analyses are essential components of risk assessment. Enteric bacteria that are endemic to specific hosts have a potential role as...

Analysis of Bacteroidales 16S rRNA gene sequences from a geographically isolated human population

Creator:: Petersen, Carolyn A.
Abstract:: Standard methods of measuring fecal pollution in water do not distinguish between human and non-human sources. Molecular technology enabled the development of host-specific markers that distinguish fecal sources. Human specific PCR primers, HF183F and HF134F, were designed based on phylogenetic analyses of partial 16S rRNA gene sequences from the Bacteroidales...

Stable isotope probing of the ovine rumen for RDX degrading microorganisms

Creator:: Mitchell, Edward A.
Abstract:: The anaerobic and highly reductive conditions found in the ovine rumen are considered favorable for the degradation of the nitroaromatic explosives such as hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX). In this study, we used stable-isotope-probing to determine the bacteria responsible for the degradation of RDX in the rumen. Results indicate 10 μg mL⁻¹ (45...

Studies on glucose-6-phosphate dehydrogenase obtained from Vibrio marinus, an obligate marine psychrophile

Creator:: Miller, Wayne Warren
Abstract:: Four-fold partially purified glucose-6-phosphate dehydrogenase (G-6-PDH) from the obligately psychrophilic marine bacterium Vibrio marinus was effected by thermally induced leakage of the enzyme, ammonium sulfate fractionation and column chromatography on Sephadex G-200 gel. The effects of temperature, pressure, salinity, and pH were determined for the various degrees of enzyme purity....

Development of immunological memory in rainbow trout (Oncorhynchus mykiss) and aflatoxin B₁ modulation of the response

Creator:: Arkoosh, Mary
Abstract:: Immunological memory has been shown to occur unequivocally in mammals. However, controversy exists regarding the capability of fish to elicite a memory response. This study demonstrates that memory does occur rainbow trout, Oncorhynchus rnykiss. Trout injected with a T-dependent antigen, trinitrophenylated keyhole-limpet hemocyanin, (TNP-KLH) (100 μg/fish) were able to produce...

Sterol assimilation by Saccharomyces cerevisiae

Creator:: Lewis, Thomas A.
Abstract:: Sterols of the yeast Saccharomyces cerevisiae are found in membranes with a free C-3,β hydroxyl group or stored in lipid droplets as esters of long-chain fatty acids. We have examined the distribution of cholesterol into free sterol and steryl ester pools of a sterol auxotrophic strain of Saccharomyces cerevisiae. Varying...

The MAV_4644 dual-function channel protein with putative ADP-ribosyltransferase activity of Mycobacterium avium is required for virulence within host macrophages

Creator:: Lewis, Matthew S.
Abstract:: Mycobacterium avium subspecies hominissuis (MAH) is an opportunistic pathogen that is ubiquitous in the environment and often isolated from faucets and showerheads. MAH mostly infects humans with an underlying disease, such as chronic pulmonary disorder (COPD), cystic fibrosis (CF), or are immunocompromised, though infections in patients without concurrent disease are...

The Oregon sockeye salmon virus : A. Biophysical biochemical characteristics B. antigenic relationship to two other salmonid viruses

Creator:: McCain, Bruce B.
Abstract:: The Oregon sockeye salmon virus (OSV) was isolated from diseased sockeye salmon (Oncorhynchus nerka) fingerlings in 1958 by J. L. Fryer. Experimentation performed prior to the research reported herein indicated that the OSV contained essential lipids, was 100 to 300 mμ in size, and possessed RNA (presumptively identified by 5-bromodeoxyuridine...
