Bacterial Predation in Host Microbiomes

Creator:: Welsh, Rory M.
Abstract:: In host-associated microbiomes, the mechanisms that regulate community composition or the principles that govern dynamics remain far from clear. However, understanding how the structure of microbial communities shift as the system moves away from a healthy state is critical to assessing disease progression and to formulate any potential mitigation strategy....

Species- and Temporal-Specific Coral Microbiome Fluctuations in Response to a Natural Bleaching Event

Creator:: Ewton, Erica M.
Abstract:: Corals provide a diversity of ecosystem services, are among the most biologically diverse ecosystems on Earth, and directly support ~500 million people globally; however, corals are increasingly experiencing significant threats and are undergoing severe bleaching events as the result of the warming climate. Using a two-year data set surrounding a...

Characterization of germination of Clostridium perfringens spores from various sources

Creator:: Alnoman, Maryam M.
Abstract:: Clostridium perfringens is a pathogenic anaerobic bacterium able to produce more than 17 toxins, allowing C. perfringins to cause a wide variety of diseases in humans and animals. Beside toxins production, C. perfringens able to form a highly resistance spores can survive in the environments for years. These spores are...

Reef Microbiomes of Mo'orea, French Polynesia, a Socio-Ecological Island System

Creator:: McConnell, Kaitlin M.
Abstract:: At a time of rapid global change, a socio-ecological system (SES) approach can provide a framework through which to quantify and communicate the risks and uncertainties of coupled human-natural systems. Islands, and tropical coral reef islands in particular, can be excellent models for SES research since they may be considered...

Disturbance Driven Colony Fragmentation as a Driver of a Coral Disease Outbreak

Creator:: Brandt, Marilyn E., Smith, Tyler B., Correa, Adrienne M. S., and Vega-Thurber, Rebecca
Abstract:: In September of 2010, Brewer's Bay reef, located in St. Thomas (U.S. Virgin Islands), was simultaneously affected by abnormally high temperatures and the passage of a hurricane that resulted in the mass bleaching and fragmentation of its coral community. An outbreak of a rapid tissue loss disease among coral colonies...

Analysis of salmonid leukocytes purified by hypotonic lysis of erythrocytes

Creator:: Crippen, Tawni L., Bootland, Linda M., Leong, Jo-Ann C., Fitzpatrick, Martin S., Schreck, Carl B., and Vella, Anthony T.
Abstract:: A technique that uses hypotonic lysis of erythrocytes was optimized for the purification of leukocytes from the peripheral blood and anterior kidney (pronephros) of rainbow trout Oncorhynchus mykiss. Comparisons of initial blood dilution (1:2, 1:4, and 1:6) and the time of exposure to hypotonic conditions (10, 20, and 40 s)...

Macroalgae Decrease Growth and Alter Microbial Community Structure of the Reef-Building Coral, Porites astreoides

Creator:: Thurber, Rebecca Vega, Burkepile, Deron E., Correa, Adrienne M. S., Thurber, Andrew R., Shantz, Andrew A., Welsh, Rory, Pritchard, Catharine, and Rosales, Stephanie
Abstract:: With the continued and unprecedented decline of coral reefs worldwide, evaluating the factors that contribute to coral demise is of critical importance. As coral cover declines, macroalgae are becoming more common on tropical reefs. Interactions between these macroalgae and corals may alter the coral microbiome, which is thought to play...

Characterization of Mycobacterium avium subsp. hominissuis Interactions with Host Macrophages and Multinucleated Giant Cells

Creator:: Joseph, Jayanthi J.
Abstract:: To examine the macrophage response to M. avium, I compared inflammasome and cytosolic sensor expression and activation. My result demonstrated that virulent strains of M. avium (A5 and 104) suppress IL-1β production and induce IFN-β production in macrophages. M. avium mutants deficient at DNA export in the biofilm exhibited reduced...

Roles of brca2 (fancd1) in Oocyte Nuclear Architecture, Gametogenesis, Gonad Tumors, and Genome Stability in Zebrafish

Creator:: Rodriguez-Mari, Adriana, Wilson, Catherine, Titus, Tom A., Canestro, Cristian, BreMiller, Ruth A., Yan, Yi-Lin, Nanda, Indrajit, Johnston, Adam, Kanki, John P., Gray, Erin M., He, Xinjun, Spitsbergen, Jan, Schindler, Detlev, and Postlethwait, John H.
Abstract:: Mild mutations in BRCA2 (FANCD1) cause Fanconi anemia (FA) when homozygous, while severe mutations cause common cancers including breast, ovarian, and prostate cancers when heterozygous. Here we report a zebrafish brca2 insertional mutant that shares phenotypes with human patients and identifies a novel brca2 function in oogenesis. Experiments showed that...

Substrate capture by a psychrophilic marine bacterium

Creator:: Geesey, G. G.
Abstract:: Cells of the marine bacterium, Ant-300, accumulate loosely bound amino acids during amino acid uptake. The fraction of amino acid taken up that exists in the loosely bound state depends on the substrate in question. Shock treatment studies indicate that, in general, the initial binding, uptake, and retention of amino...
