Vibrio cholerae Phage K139
Bisher sind ca. 190 verschiedene Vibriophagen beschrieben, nur 10 davon stellen filamentöse Phagen dar, der Rest gehört zu den sogenannten Caudovirales, d.h. sie weisen ein kubisches Nukleokapsid mit einem mehr oder weniger langen Schwanz auf. Der letzteren Gruppe ist auch der Phage K139 …

ENGINEERING PHAGE HOST RANGE PROMISCUITY
Bacteriophages, viruses that infect bacteria, are the most abundant biological entities on earth and one of the most potent evolution-driving forces in nature due to their capacity to facilitate horizontal gene transfer. Tailed bacteriophages have been studied intensively, and they rely on tail …

WIP1 Phage Specificity for B. Anthracis
<p>Bacteriophage-based diagnostics and therapeutics have been recognized as tools to combat bacterial infections for nearly a century. Wip1 is a recently isolated phage that infects Bacillus anthracis, the notorious biothreat pathogen and gram-positive bacterium that causes anthrax disease. The …

Characterization of the Gifsy-1 Phage Excisionase
The Gifsy-1 phage is a temperate bacterial virus that infects its host, Salmonella enterica serovar Typhimurium. During lysogeny, the phage integrates site-specifically into a single bacterial attachment sequence in the Salmonella chromosome. The reaction involves recombination between the phage …

Investigations into the Phage-Host Dynamics of Streptomyces
Bacteriophage (phage) infection poses a major risk to bacteria, and as such most bacteria have evolved myriad defences to protect against it. Streptomyces bacteria are a genus of the order Actinomycetales and are characterized by their complex lifecycle and prodigious production of secondary or …

Studies of a Novel Phage Lytic Enzyme, PlySs2
… pathogens. We identified a novel bacteriophage lysin, derived from an S. suis phage termed PlySs2 (phage lysin from S. suis 2). This thesis is divided into four main sections detailing PlySs2: characterization (chapter 2); activity against S. suis (chapter 3); broad lytic activity (chapter …

Covalent DNA Modifications in Phage and Bacterial Dynamics
… wellbeing. This study examines how bacteria and phage interact through bacterial nucleases that restrict infection, such as restriction enzymes and CRISPR systems, and the covalent DNA modifications that neutralize them. Multiple targeted nucleases equip bacteria with an innate immune response …

A Restriction Analysis of Klebsiella Pneumoniae Phage SBS
<p>A Klebsiella phage was isolated from the San Bernardino sewage and its physiochemical properties analyzed. The present study found the density of the phage to be 1.44 g/ml, the burst size to be 10, and the phage had a latent period of 20-25 minutes. The DNA was found to be double stranded and …

Applying phenotypic phage selection to Chlamydia trachomatis infection
… can be identified by target based or phenotypic phage display. Here, phenotypic phage display was performed in two ways: (1) on a population of cells infected with *Ctr* or (2) on EB-enriched material derived from lysed, infected cells. In (1), panning for antigens was performed on the surface of …

Statistically inferring the mechanisms of phage-host interactions
Bacteriophage and their hosts are locked in an age-old arms race. Successful bacteria are subject to predation, forcing the population to diversify, and phage are also quick to adapt tactics for infecting these potential hosts. Sampling of closely related bacterial strains that differ in phage …

Temporal gene expression and regulation in T4 phage
… biological entity in the biosphere, bacteriophages play a critical role in shaping the microbial diversity, and thus overall ecosystem health. They are also essential tools in molecular biology, shedding light on fundamental biological concepts. T4 phage, with its complex lifecycle and …

Mapping The Human Vasculature By In Vivo Phage Display
<p><em>In vivo</em> phage display screenings by intravenous injection of a random phage-displayed peptide library allow for the selection of peptides that localize to specific vascular beds. At the University of Texas MD Anderson Cancer Center, we have had the opportunity to perform phage display …

Characterization of the repressor from the lambdoid phage HK022.
The lambdoid coliphage HK022 can grow in either a lytic or lysogenic mode following infection. In λ phage the switch to either mode is controlled by the cI and Cro repressors which bind to operators in the λ chromosome and regulate gene expression of adjacent promoters. HK022 is organized similar …
