View their research summaries below:
Summary: Bacteria and archaea have evolved adaptive defense mechanisms called CRISPR (clustered regularly interspaced short palindromic repeats)-Cas (CRISPR-associated) systems to protect themselves against invading phages and plasmids. CRISPR-Cas systems store small pieces of invader DNA in the CRISPR array, which functions as a molecular memory bank. CRISPR-RNA (crRNA) molecules are derived from the memory bank and guide surveillance complexes to invading DNA. A sequence match between the crRNA-DNA marks the DNA for destruction. Discovered in the last decade, these defense mechanisms have been the focus of much research and have led to the development of new biotechnological tools. My research is focused on understanding the molecular mechanisms of RNA guided surveillance in the type I-E CRISPR-Cas system of Escherichia coli.
Summary: Pseudomonas aeruginosa forms biofilm and causes chronic infections in cystic fibrosis lung and chronic wounds. Biofilm-associated infections are a major concern for public health due to their high antibiotic resistance. Dormant subpopulation resides in nutrient and oxygen limited region of biofilms are highly antibiotic resistance, suggesting the importance of dormancy for persisting biofilmassociated infections. Dormant cells must maintain their cellular integrity during dormancy. We previously found that hibernation promoting factor (HPF) is important for the preservation of ribosome and maintenance of cell viability during starvation. In this study, we will determine the change in ribosome abundance and cell viability in subpopulations of cells in P. aeruginosa biofilms during starvation using fluorescence in situ hybridization (FISH) and fluorescence activated cell sorting (FACS) followed by drop plating. In combination with antibiotic treatments, our findings will serve as a foundation to identify new therapeutic targets to eliminate biofilm-associated chronic infections.
May 2015 - Two Graduate Students from the Fields Lab Receive ASM Travel Awards

Laura and Greg will present their research in New Orleans at the 115th General Meeting of the ASM. View their research summaries below:
Abstract: Symbiosis is widespread throughout the biosphere with well-studied examples in and across all three domains of life. In communities of bacteria and archaea, mutualism is typically referred to as syntrophy (“eating together”) whereby-products of one metabolism serve as substrates for another metabolism. The syntrophy between sulfate-reducing bacteria (SRB) and methanogenic archaea is of interest because these guilds both play crucial roles in many different anaerobic environments. In the absence of sulfate as an electron acceptor and the addition of the hydrogenotrophic methanogen, Methanococcus maripaludis, the two cell types are interdependent via previously proposed product inhibition syntrophy, and cross feeding of by-products allows a cooperative syntrophic relationship to be established. In monocultures, only D. vulgaris Hildenborough readily forms biofilm, and the topography of the biofilm is relatively flat and thin. However, the co-culture biofilm is evenly interspersed with M. maripaludis, and is thicker and filled with topographical features such as ridges, spires, and valleys. We have recently demonstrated that M. maripaludis exhibits taxis toward hydrogen, or hydrogenotaxis, as well as showing that biofilm helps optimize the carrying capacity of the syntrophic coculture. In order to better understand the interactions between M. maripaludis and D. vulgaris Hildenborough, RNA-Seq was used to create a transcriptomic profile of the coculture biofilm as compared to the planktonic mono- and co- culture states. Our results suggest that key steps in methanogenesis are down-expressed for M. maripaludis and electron transfer related genes are down-expressed for D. vulgaris Hildenborough. Many of the up-expressed genes include hypothetical proteins but also include cell surface modifications, communication via small metabolites, N-cycling, and metal homeostasis. This is in direct contradiction with results published for work done with similar coculture systems in the planktonic growth mode, thereby indicating that the biofilm growth mode is both phenotypically and physiologically unique most likely due to mass transport considerations inside and outside the biofilm.
Abstract: Microbially Induced Corrosion (MIC) is a major concern for industrial ferrous metal pipelines and can result in pipeline failure. Sulfate Reducing Bacteria (SRB) have been implicated in contributing to MIC due to their production of corrosive H2S gas and elemental sulfur along with metal-microbe interactions. This project focuses on the effects of electron donor limitation and electron acceptor limitation on biofilm physiology and corrosion rate on carbon steel versus stainless steel and glass surface materials. Desulfovibrio alaskensis G20 was grown under steady-state conditions in sulfate-reducing biofilm reactors. Batch cultures grown under EAL and EDL conditions had similar maximum growth rates, but differed significantly in final cell yields at 37C. Under EAL conditions, biofilms on glass had elevated biomass levels, and higher protein levels were detected on 316 steel compared to 1018 steel. At later time points, the 1018 steel had an elevated carbohydrate to protein ratio. Under EDL conditions, biofilms on glass had the highest protein levels; 316 and 1018 steel had similar biofilm protein levels. Hexose-equivalents were similar for the three tested surfaces under EDL conditions and slightly elevated for 1018 steel compared to glass and 316 steel. In addition, under EDL conditions, 1018 steel also had an elevated carbohydrate to protein ratio. Differential corrosion rates were observed between electron donor limiting (EDL) and electron acceptor limiting (EAL) conditions on 1018 carbon steel and 316 stainless steel. The results indicated that different ratios of respiration substrates contributed to altered rates of corrosion, and the difference in corrosion rates could not be explained solely by sulfide, acetate, or carbohydrate levels. The presented results are the first report of increased mass loss under EDL conditions using a defined medium under steady-state conditions.

The Department of Microbiology and Immunology would like to congratulate AnneMarie Criddle, from the lab of Matthew Taylor[BROKEN LINK], for her recognition at the 40th West Coast Biological Sciences Undergraduate Research Conference for an Outstanding Oral Presentation in Microbiology. View her research summary below:
Coinfection is the ability of two viruses to infect the same cell, a situation required for recombination between the two viral genomes. HSV and its model system, Pseudorabies virus (PRV), have demonstrated exclusion of other herpes viruses by expressing glycoprotein D (gD) on the surface of infected cells. It was previously shown that viral exclusion of HSV by gD occurred between four and six hours post infection. Our aim was to use fluorescent expressing viruses to quantify viral exclusion at a cellular level and refine this exclusion time window.
Pig epithelial cells were infected with two fluorescent protein encoded viruses. Delaying the second inoculum allowed us to visualize when exclusion was occurring at a cellular level. Infected cells were imaged using an epifluorescent microscope and quantified using viral titering and fluorescent activated cell sorting. It was found that an exclusion event was occurring at two hours post infection of the initial inoculum. Supporting these results, the addition of cycloheximide showed an increase of the secondary inoculum, suggesting that immediate/early viral proteins are necessary. Future work involves investigating this early mechanism of exclusion using a gD null virus to determine if this viral exclusion mechanism is gD independent.
April 2015 - Postdoctoral Researcher, Luke McKay, receives NASA Fellowship
