A Lipidomics Approach To The Viral-Host Dynamics Of The Unicellular, Eukaryotic Alga Chlorella Variabilis And Its Viral Pathogen, Pbcv-1, Suzanne Rose Dec 2015

A Lipidomics Approach To The Viral-Host Dynamics Of The Unicellular, Eukaryotic Alga Chlorella Variabilis And Its Viral Pathogen, Pbcv-1, Suzanne Rose

Dissertations and Theses in Biological Sciences

This thesis focuses on the sterol and sphingolipid composition in the unicellular, green alga Chlorella variabilis and the lipidomic changes that occur during viral infection. Using lipid analysis by mass spectrometry, we have identified the major sterol, ergosterol and sphingolipid, glucosyl inositol phosphoceramide (GIPC) as constituents of C. variabilis cell membranes. Sterols and sphingolipids have essential biological functions such as hormone-based signaling, plant defense, and apoptosis as well as critical roles in structural components of the cell and organelle membranes. In chapters two and three, we focus on the characterization of sterol composition among both freshwater and marine alga and ...

Human Sewage Identified As Likely Source Of White Pox Disease Of The Threatened Caribbean Elkhorn Coral, Kathryn Sutherland, James Porter, Jeffrey Turner, Brian Thomas, Erin Looney, Trevor Luna, Meredith Meyers, J. Futch, Erin Lipp

Kathryn Patterson Sutherland PhD

Caribbean elkhorn coral, Acropora palmata, has been decimated in recent years, resulting in the listing of this species as threatened under the United States Endangered Species Act. A major contributing factor in the decline of this iconic species is white pox disease. In 2002, we identified the faecal enterobacterium, Serratia marcescens, as an etiological agent for white pox. During outbreaks in 2003 a unique strain of S. marcescens was identified in both human sewage and white pox lesions. This strain (PDR60) was also identified from corallivorious snails (Coralliophila abbreviata), reef water, and two non-acroporid coral species, Siderastrea siderea and Solenastrea ...


Dark Spots Disease Increase In Scleractinian Corals In Bonaire, D.C., Jennifer Mathe Jan 2015

Dark Spots Disease Increase In Scleractinian Corals In Bonaire, D.C., Jennifer Mathe

Honors Theses

Pathogen-host relation dynamics have adjusted in the Caribbean due to increased epizootic events and decreased coral cover resulting from anthropogenic influences. Reef-building corals are being infected by numerous diseases including dark spots disease, a ubiquitous Caribbean disease of an unknown agent. The objectives of this study were to quantify the change in dark spots disease prevalence in Siderastrea siderea and Stephanocoenia spp. from 1998 to 2014 and determine influencing conditions on prevalence and infection severity of disease. The abundance of benthic organisms and substrate types were also quantified. A 1350 m2 area between six sites on Bonaire was surveyed using ...
