Dissertation (1)

A Study of Surface Motility and Biofilm Formation in Pseudomonas aeruginosa Quorum Sensing and Photodynamic Antimicrobial Chemotherapy (Tracy L. Collins) Faculty Dissertations (2010)

Pseudomonas aeruginosa is an opportunistic pathogen that commonly causes infection in immunocompromised individuals. This bacterium forms complex communities known as biofilms. Biofilm formation is dependent on motility as well as quorum-sensing. In this study, we ...

Patents (1)

Combination Therapy and Methods for Treating Bacterial Biofilms (Jayne B. Robinson and Tracy L. Collins) Science and Mathematics Faculty Patents (2013)

A combination therapy for treating a bacterial biofilm comprises a therapeutically effective amount of an antibiotic comprising an aminoglycoside or tetracycline, or a combination of two or more thereof, and a cationic porphyrin in an ...

Journal Articles (2)

The Effect of a Cationic Porphyrin on Pseudomonas aeruginosa Biofilms (Tracy L. Collins, Elizabeth A. Markus, Daniel J. Hassett, et al.) Current Microbiology (2010)

Current studies have indicated the utility of photodynamic therapy using porphyrins in the treatment of bacterial infections. Photoactivation of porphyrins results in the production of singlet oxygen (1O2) that damages biomolecules associated with cells and ...

PilJ Localizes to Cell Poles and Is Required for Type IV Pilus Extension in Pseudomonas aeruginosa (Paul A. DeLange, Tracy L. Collins, George E. Pierce, et al.) Current Microbiology (2007)

Twitching motility allows Pseudomonas aeruginosa to respond to stimuli by extending and retracting its type IV pili (TFP). PilJ is a protein necessary for this surface-associated twitching motility and bears high sequence identity with Escherichia ...

Conference Presentations (4)

Natural and Constructed Wetlands Capable of Anaerobic and Aerobic Degradation of Chlorinated Ethenes (J. Amon, Tracy L. Collins, D. Duell, et al.) Society of Wetland Scientists Annual Meeting (2012)

The Effect of a Cationic Porphyrin on the Viability of Pseudomonas Aeruginosa and the Generalized Transducing Phage (E. Markus, E. Raphael, Tracy L. Collins, et al.) The 110th Annual American Society for Microbiology Meeting (2010)

The Effect of a Cationic Porphyrin on Pseudomonas Aeruginosa biofilms (E. Markus, Tracy L. Collins and J. Robinson) 22nd Annual Bro. Joseph Stander Symposium (2010)

Proteomic Analysis of P. aeruginoas to E,E-farnesol, a Quorum-sensing Compound of Candida Albicans (S. Jones-Dozier, Tracy L. Collins, J. Robinson, et al.) The 3rd ASM Cell-Cell Communication in Bacteria (2007)

Poster Presentations (8)

E,E-farnesol Inhibits Swarming Motility in Burkholderia cepacia Through Rhamnolipid Production (Stephanie E. Nicholls, Alayna N. Sanderson, Andrea P. Schwartz, et al.) The Research and Scholarship Symposium (2013-2019) (2017)

Burkholderia cepacia and Candida albicans both exhibit cell-to-cell communication through the use of quorum-sensing molecules (QSM) known as autoinducers. E,E-farnesol is a QSM produced by C. albicans which regulates its conversion from yeast to mycelium. ...

The Effect of Photoactivated TMP on Burkholderia cepacia Biofilms (Reyna G. Osorio, Chandra N. Swiech and Tracy L. Collins) The Research and Scholarship Symposium (2013-2019) (2017)

Burkholderia cepacia is an opportunistic pathogen that causes infections in immunocompromised individuals such as cystic fibrosis patients. B. cepacia infections are typically characterized by the formation of complex communities of cells known as biofilms. Because ...

Farnesol is Sensed by PilJ and Inhibits Surface Motility in Pseudomonas aeruginosa (Tracy L. Collins, M. Connolly and J. Robinson) 19th Annual Bro. Joseph Stander Symposium (2007)

Farnesol is Sensed by PilJ and Inhibits Surface Motility in Pseudomonas aeruginosa (Tracy L. Collins, M. Connolly and J. Robinson) 106th Annual American Society for Microbiology Meeting (2006)

Farnesol is Sensed by PilJ and Inhibits Surface Motility in Pseudomonas aeruginosa (Tracy L. Collins, M. Connolly and J. Robinson) 115th Annual Meeting on Science and Engineering on a Nanoscale by the Ohio Academy of Science (2006)

PilJ is a MCP and is necessary for Type IV pili biogenesis and Function in Pseudomonas aeruginosa (P. DeLange, Tracy L. Collins and J. Robinson) 17th Annual Bro. Joseph Stander Symposium (2005)

PilJ is a MCP and is necessary for Type IV pili biogenesis and Function in Pseudomonas aeruginosa (P. DeLange, Tracy L. Collins and J. Robinson) Sigma Xi (2004)

PilJ is a MCP and is necessary for Type IV pili biogenesis and Function in Pseudomonas aeruginosa (P. DeLange, Tracy L. Collins and J. Robinson) 104th Annual American Society for Microbiology Meeting (2004)
