- PIAAMV is a growth medium that I developed which activates alginate overproduction and several other cystic fibrosis-relevant phenotypes. Here is this study, we determined all of the genes required for alginate production on PIAAMV. We next analyzed the transcriptional response due to growth on PIAAMV. And third, we observed that growth on PIAAMV attenuates P. aeruginosa in a mouse acute pneumonia model of infection. And finally, we observed the mice immunized with P. aeruginosa grown on PIAAMV are protected from future infections, indicating PIAAMV may be useful as a novel attenuated live vaccine strategy.

- 20th Most-Read article in Journal of Bacteriology in the month of March 2012
- Microarray analysis, proteomics, phenotypic analysis, and an acute pneumonia model were used to show that the sensor kinase KinB is not only a regulator of the exopolysaccharide alginate, but also directly controls virulence of the bacterium.

- This publication laid the foundation for most of my current research and best exemplifies my postdoctoral studies. In this work, a novel medium was formulated which activates multiple phenotypes that are currently observed in cystic fibrosis isolates. The medium, PIAAMV, induces alginate overproduction mimicking the stress responses that P. aeruginosa activates for survival in the lung.

- Typically regulated proteolysis of MucA by protease AlgW is the initial proteolytic event leading to alginate overproduction. However, here an exception to that dogma was observed where protease MucP could directly activate proteolysis.

- Activation of alginate overproduction causes expression of co-regulated factors. LptF is highly up-regulated in mucoid and cystic fibrosis strains and provides the bacterium with several advantageous phenotypes.

- This publication is the key work of my Ph.D. research. KinB is a sensor kinase that regulates alginate overproduction. In the absence of kinB, regulated proteolysis of MucA occurs. It is possible that KinB senses environmental conditions and activates alginate overproduction through AlgB and RpoN transcription factors.
