Vibriobactin Mediated Biofilm Formation in Vibrio cholerae 2013 2046 Vibrio cholerae transitions between a free-swimming planktonic lifestyle and a multicellular community called a biofilm, which is used as protection from environmental stressors. The objective of this study was to analyze the role of vibriobactin in ...
A Novel Norspermidine Responsive Signaling Pathway in Vibrio Cholerae Affecting Biofilm Formation 2013 1496 Polyamines are a class of simple molecules that are nearly ubiquitous to life. As signals they are involved in cell signaling and cellular processes. In the aquatic pathogen Vibrio cholerae it has been shown that the polyamine norspermidine dramatica...
Regulation of Biofilm Formation and Norspermidine Production by Iron in Vibrio Cholerae 2015 1536 Vibrio cholerae is a pathogenic bacterium and the causative agent of the diarrheal disease cholera. V. cholerae is thought to persist in the environment in the form of a biofilm. Biofilm formation is regulated by signals ranging from self produced ...
Characterization of the norspermidine/spermidine ABC-type transporter, PotABCD1, in Vibrio cholerae 2015 1672 Vibrio cholerae is an intestinal pathogen that also thrives in aquatic environments through forming biofilms, matrix-bound aggregation of cells offering physical protection from many environmental stressors. Formation of biofilm can be regulated by ...
The Effect of Polyamines on Vibrio cholerae Virulence Properties 2012 2456 Vibrio cholerae is the causative agent of the severe enteric disease, cholera. To be a virulent strain, the bacterium must be able to synthesize both cholera toxin and toxin-coregulated pilus (TCP). TCP has been shown to mediate microcolony formati...
Characterization of Protein-Protein Interaction Within a Polyamine Responsive Signaling System in Vibrio Cholerae 2012 2811 The Gram-negative bacterium Vibrio cholerae is a natural inhabitant of aquatic environments and the causative agent of the severe diarrheal disease cholera. This bacterium is able to form biofilms on both abiotic and biotic surfaces. Biofilm formatio...
Characterization of the Norspermidine/Spermidine Transport Protein, PotD1, in Vibrio cholerae 2012 2599 Biofilm formation increases antibiotic resistance among bacteria; therefore, a thorough understanding of the proteins and molecules affecting biofilm formation is necessary. PotD1, the substrate binding protein of the PotABCD1 spermidine transport sy...
Investigating The Role Of Putrescine Transport And Biosynthesis In Vibrio Cholerae Biofilm Formation. 2016 1249 Biofilms are structures formed by most bacteria, and in Vibrio cholerae they provide protection and passage through the gastric acid barrier. V. cholerae is the causative agent of the cholera disease. Formation of biofilms is regulated by a wide vari...
Characterization of the NspS-MbaA signaling system controlling biofilm formation from polyamine input to phenotypic output 2015 1104 Biofilm formation plays a critical role in the infectious cycle of the bacterial pathogen, Vibrio cholerae. The polyamine, norspermidine, has a positive influence on biofilm formation while spermidine has the opposite effect. These influences occur t...
Construction Of A ?mbaA?potD1 Mutant And The Effects On Biofilm Formation In Vibrio Cholerae 2016 1033 Vibrio cholerae is a bacterial species identified as the causative agent of the diseasecholera. Similar to other aquatic bacteria, V. cholerae forms complex communities ofmicroorganisms bounded by a polysaccharide matrix, known as biofilms. Biofilms ...
Characterization Of The Norspermidine-Preferential Abc-Type Transporter Potabcd1 In V. Cholerae Biofilm Formation 2016 1242 This study further characterizes the Vibrio cholerae norspermidine/spermidine ABC-type transporter PotABCD1. The role of this transporter in biofilm formation is relevant to two diverse phases of the V. cholerae life cycle: survival in the aquatic e...
The Role Of SpeG In Vibrio Cholerae Biofilm Formation 2017 1667 Vibrio cholerae is a Gram-negative, aquatic bacterium responsible for the human disease cholera. Illness typically results from ingestion of the bacterium in its biofilm form. It is known that polyamines regulate biofilm formation. V. cholerae can up...
A Novel Mutagenic Screen Reveals A Model For Interaction Between The Biofilm Regulatory Proteins NspS And MbaA In Vibrio Cholerae 2019 369 The transition between motility and biofilm formation is important to the lifecycle of the human pathogen Vibrio cholerae, which causes the disease cholera. Polyamines are ubiquitous, organic molecules and an example of one environmental signal that ...
NspS, A PotD1 Homolog, Acts as a Spermidine Signal Sensor, Not a Transporter, in Vibrio Cholera 2010 1902 Biofilm formation is important for the survival of Vibrio cholerae in its natural aquatic environments and within the human intestinal tract. We have previously shown that the absence of PotD1, the periplasmic binding protein for the spermidine ABC t...
Construction Of A [delta]vpsL[delta]potB Mutant And The Effects On Biofilm Formation In Vibrio cholerae 2018 655 Vibrio cholerae is a Gam-negative, pathogenic bacterium known as the causative agent of the intestinal disease cholera. Infection is linked to ingestion of contaminated water. Four hundred million people worldwide are without safe or up to standard d...
Characterizing The Domains Of The Biofilm Regulator MbaA In Vibrio Cholerae 2018 859 Vibrio cholerae is a pathogen that is believed to survive within its environment in a biofilm state but can only cause infection in a planktonic state. Polyamines modulate biofilm formation and are sensed by the periplasmic protein NspS. NspS is then...
The Effect Of Polyamines And Biofilm Formation On Zebrafish Colonization By Vibrio cholerae 2019 525 Vibrio cholerae, the intestinal pathogen responsible for the diarrheal disease cholera, is an aquatic bacterium that utilizes biofilms as an integral part of its life cycle. Biofilms are clusters of cells, which are surrounded by and contained within...
Assessment Of Microbial Communities In High Altitude Wetlands Disturbed By Iron And Manganese 2009 308 The Sorrento wetland is a high altitude wetland that has been disturbed due to anthropogenic activity. It has been previously established that this disturbance has led to several Fe and Mn seeps that contribute to high levels of Fe and Mn in stream a...
