Nano-based Detection

Our research focuses primarily on the molecular and cell biology of Mycoplasma pneumoniae, which causes bronchitis and primary atypical or "walking" pneumonia in humans. M. pneumoniae is responsible for about 20% of all pneumonias and is the leading cause of pneumonia in older children and young adults. Adherence to respiratory epithelium is mediated by a polar differentiated terminal organelle, which also constitutes the motor for gliding motility. Gliding and cytadherence are essential for mycoplasmas to evade mucociliary clearance and establish infections, and we use a normal human bronchial epithelium model to explore early events in infection of the conducting airways. A major goal of our research is to define the organization, assembly, regulation, and functional maturation of the terminal organelle in cytadherence and gliding motility and thereby identify new targets for intervention. In addition, with colleagues in the UGA Nanoscale Science and Engineering Center, we are using nanorod array-surface enhanced raman spectroscopy as a diagnostic platform for the rapid and effective detection of mycoplasmas in human and poultry infections.
