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...

Automated and Accurate Estimation of Gene Family Abundance from Shotgun Metagenomes

Creator:: Nayfach, Stephen, Bradley, Patrick H., Wyman, Stacia K., Laurent, Timothy J., Williams, Alex, Eisen, Jonathan A., Pollard, Katherine S., and Sharpton, Thomas J.
Abstract:: Shotgun metagenomic DNA sequencing is a widely applicable tool for characterizing the functions that are encoded by microbial communities. Several bioinformatic tools can be used to functionally annotate metagenomes, allowing researchers to draw inferences about the functional potential of the community and to identify putative functional biomarkers. However, little is...

Vitamin B₁₂ production and depletion in a naturally eutrophic lake

Creator:: Gillespie, P. A.
Abstract:: The vitamin B₁₂ concentrations in both the water and sediments of Klamath Lake were found to vary significantly during a one-year period. The patterns of B₁₂ distribution were remarkably similar among the three main sites. In all cases there was an extremely sharp gradation in concentration in relation to depth...

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...

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...

Characterization of thermophilic rod and coccus starter strains used in mozzarella cheese manufacture

Creator:: Faessler, Patrick Charles
Abstract:: The present investigation was undertaken to characterize a number of strains of Lactobacillus bulgaricus and Streptococcus thermophilus intended for use by a commercial starter supply company. Thorough characterization of each culture was required in order to combine compatible strains so that their usefulness in Mozzarella cheese manufacture would be maximized....

Characterization of an immunoreactive region of the major capsid protein for infectious pancreatic necrosis virus

Creator:: Barrie, Rosemary Jean
Abstract:: DNA fragments of the gene for VP2, the major capsid protein of Infectious Pancreatic Necrosis Virus (IPNV), were expressed in Escherichia coli and characterized immunologically with antisera made to different serotypes of IPNV. The entire VP2 gene was excised from the plasmid pUC19/A+SΔK and fragmented with restriction enzyme Sau3A1. The...

An analysis of Sargasso Sea bacterioplankton diversity using 16S ribosomal RNA

Creator:: Britschgi, Theresa Baden
Abstract:: The objective of this project was to use ribosomal RNA genes, cloned from natural populations of Sargasso Sea bacterioplankton, as markers for picoplankton diversity. It is widely recognised that a majority of microorganisms have yet to be cultivated, and therefore much of extant microbial diversity remains unknown (50). The method...
