Improving Risk Models for Avian Influenza: The Role of Intensive Poultry Farming and Flooded Land during the 2004 Thailand Epidemic
(PLos One, 2012-11-19)
Since 1996 when Highly Pathogenic Avian Influenza type H5N1 first emerged in southern China, numerous studies sought risk factors and produced risk maps based on environmental and anthropogenic predictors. However little ...
Transcriptional Regulator PerA Influences Biofilm-Associated, Platelet Binding, and Metabolic Gene Expression in Enterococcus faecalis
(PLos One, 2012-04-04)
Enterococcus faecalis is an opportunistic pathogen and a leading cause of nosocomial infections, traits facilitated by the ability to quickly acquire and transfer virulence determinants. A 150 kb pathogenicity island (PAI) ...
Tracing the Rise of Ants - Out of the Ground
(PLos One, 2013-12-26)
The evolution of ants (Hymenoptera: Formicidae) is increasingly well-understood due to recent phylogenetic analyses, along with estimates of divergence times and diversification rates. Yet, leading hypotheses regarding the ...
Physiological Roles of ArcA, Crp, and EtrA and Their Interactive Control on Aerobic and Anaerobic Respiration in Shewanella oneidensis
(PLos One, 2010-12-28)
In the genome of Shewanella oneidensis, genes encoding the global regulators ArcA, Crp, and EtrA have been identified. All these proteins deviate from their counterparts in E. coli significantly in terms of functionality ...
Hexavalent Chromium Reduction under Fermentative Conditions with Lactate Stimulated Native Microbial Communities
(PLos One, 2013-12-23)
Microbial reduction of toxic hexavalent chromium (Cr(VI)) in-situ is a plausible bioremediation strategy in electron-acceptor limited environments. However, higher Cr(VI) may impose stress on syntrophic communities and ...
Generation and Validation of a Shewanella oneidensis MR-1 Clone Set for Protein Expression and Phage Display
(PLos One, 2008-08-20)
A comprehensive gene collection for S. oneidensis was constructed using the lambda recombinase (Gateway) cloning system. A total of 3584 individual ORFs (85%) have been successfully cloned into the entry plasmids. To ...
Studies in RF Power Communication, SAR, and Temperature Elevation in Wireless Implantable Neural Interfaces
(PLos One, 2013-11-06)
Implantable neural interfaces are designed to provide a high spatial and temporal precision control signal implementing high degree of freedom real-time prosthetic systems. The development of a Radio Frequency (RF) wireless ...
Functional Biogeography as Evidence of Gene Transfer in Hypersaline Microbial Communities
(PLos One, 2010-09-23)
BackgroundHorizontal gene transfer (HGT) plays a major role in speciation and evolution of bacteria and archaea by controlling gene distribution within an environment. However, information that links HGT to a natural ...
Microbial Community Analysis of a Coastal Salt Marsh Affected by the Deepwater Horizon Oil Spill
(PLos One, 2012-07-18)
Coastal salt marshes are highly sensitive wetland ecosystems that can sustain long-term impacts from anthropogenic events such as oil spills. In this study, we examined the microbial communities of a Gulf of Mexico coastal ...
Metapopulation Dynamics Enable Persistence of Influenza A, Including A/H5N1, in Poultry
(PLos One, 2013-12-02)
Highly pathogenic influenza A/H5N1 has persistently but sporadically caused human illness and death since 1997. Yet it is still unclear how this pathogen is able to persist globally. While wild birds seem to be a genetic ...
