SPL mentors students because breakthroughs in research of waterborne pathogens like Legionella depend on it. Through our affiliation with the University of Pittsburgh and community partnerships, SPL has invested in students from the University of Pittsburgh, Carnegie Mellon University, Duquesne University, Chatham University, and Carlow University. We provide future scientists, physicians and engineers cutting-edge opportunities in Legionella research to advance their careers and Legionella prevention. Our students share their findings at national conferences and publish their research results in peer-reviewed journals. To date, many of our students have gone on to make significant discoveries in research and medicine. 

Student Publications

Professional Conferences

SPL interns and students have also presented research at professional conferences including the International Conference on Legionella and the Association for Professionals in Infection Control and Epidemiology (APIC)—several presentations resulted in publications in the American Journal of Infection Control.  

  • Evaluation of a New Point-of-Use Faucet Filter for Preventing Legionella and Total Bacteria described a field study of a point-of-use (POU) filter to limit exposure of Legionella, Pseudomonas aerguinosa and total bacteria. The field evaluation study of a new point of use filter designed to last up to 62 days was a collaboration between Special Pathogens Laboratory and a Pennsylvania healthcare facility.. The poster was presented at the annual national APIC conference in Anaheim, Calif. on June 8,  2014. (Download PDF).

  • Monochloramine Disinfection of a Hospital Water System for Preventing Hospital-Acquired Legionnaires' Disease: Lessons Learned from a 1.5 Year Study poster  gave more data of the first US field study of a monochloramine generating system in a hospital hot water system. The conclusions show monochloramine to be a promising disinfectant for Legionella. Presented at the Eighth International Conference on Legionella in October. (Download  PDF)
     
  • Use of Pyrosequencing to Determine the Effects of Monochloramine Treatment on Legionella and Associated Bacterial Populations in a Hospital Hot Water System poster. The first US study to assess changes in Legionella and microbial flora due to chloramination in a hospital's hot water system using next generation sequencing, the results show a strong reduction in Legionella presence and a lack of many issues with chloramination found in municipal water supplies. Presented at the Eighth International Conference on Legionella in October. (Download PDF)
     
  • Testing for Legionella in Healthcare Facilities: Evaluation of the Reproducibility of Legionella Test Results and the Impact of Time on Viability and Variability (Download PDF) at APIC 2013. 
     
  • Revisiting the hand wipe vs. gel rub debate: Is a higher ethanol content hand wipe more effective than an ethanol gel? Presented at APIC 2009
