The data was aggregated in several informative ways. Multiple alignments were combined with a predicted 3D-structure to reveal regions of both high and low conservation. Viewed in a phylogenetic framework, many gokushovirus MCP clades contained samples from multiple environments, although distinct clades dominated the different sample types. Some environments, particularly pelagic sediments, appear as hotbeds of gokushovirus diversity, while freshwater springs were the least diverse. The second chapter used the same primer set to detect gokushovirus communities at 0 m and 100 m depth in two seasons from three years at the Bermuda Atlantic Time- series Study (BATS) site. As a result of twenty-six years of constant sampling, the annual hydrodynamic cycling of BATS is very well understood. This wealth of knowledge allows us to hypothesize that the winter deep mixing layer will act to connect the viral communities between 0 m and 100 m. Conversely, in summer when stratification occurs, viral communities at the two depths will become divergent. We find compelling evidence to support this hypothesis. The final chapter of this thesis details continuing efforts to characterize the first non-tailed, single-stranded DNA, temperate phage to infect a member of the globally important genus of marine autotroph, Synechococcus. Efforts undertaken have spanned genomic, metagenomic and proteomic methodologies. The lack of culturable, phage-host model systems for small, single-stranded DNA phages is today one of the most glaring impediments to increased understanding of these viruses. In combination with the data presented on environmental diversity, steps taken towards establishing this Synechococcus phage as a culturable model system makes this thesis a major contribution to the understanding of environmental ssDNA phages.

This book was released on 1987-11-13. Phage Ecology available in PDF, EPUB and Kindle. This book is the first to explore the distribution, fate, and ecology of phage in the environment and point up the important applications of this information. The text begins with an historical overview, followed by a discussion of the current state of phage taxonomy. Next is covered the distribution patterns and fate of phage in diverse environments, e.g. soil, fresh water, marine water, and water and wastewater treatment plants. Factors that can influence the numbers and activity of phage populations, e.g. host and phage density, association of a phage with solids, presence of organic matter, temperature, pH, ultraviolet and visible light, concentration and types of ions present, and the metabolic activities of bacteria other than the phage host are examined. One chapter is devoted to the occurrence and implications of phage in various industries, e.g. dairy, wine, sausage, and antibiotic industries.

Download and read online ebook Bacteriophage Ecology write by Stephen T. Abedon. This book was released on 2008-05-01. Bacteriophage Ecology available in PDF, EPUB and Kindle. Bacteriophages, or phages, are viruses that infect bacteria and are believed to be the most abundant and genetically diverse organisms on Earth. As such, their ecology is vast both in quantitative and qualitative terms. Their abundance makes an understanding of phage ecology increasingly relevant to bacterial ecosystem ecology, bacterial genomics and bacterial pathology. Abedon provides the first text on phage ecology for almost 20 years. Written by leading experts, synthesizing the three key approaches to studying phage ecology, namely studying them in natural environments (in situ), experimentally in the lab, or theoretically using mathematical or computer models. With strong emphasis on microbial population biology and distilling cutting-edge research into basic principles, this book will complement other currently available volumes. It will therefore serve as an essential resource for graduate students and researchers, particularly those with an interest in phage ecology and evolutionary biology.
