Competition Funded PhD Project (European/UK Students Only)
Bacteriophages are surrogate indicators of the bacterial populations they infect; they are also readily aerosolised. In this project we combine two leading edge research programmes at Leicester to investigate how phages may be used to better understand and manage the lung diseases chronic obstructive pulmonary disease (COPD) and asthma in which the airways contain high microbial populations. When people suffer deteriorations (exacerbations) culture often detects pathogens and, despite weak evidence that these organisms are responsible, patients are treated with antibiotics. The student will use our Mask Aerosol Sampling System (MASS) to take exhaled breath samples from patients when stable and when unwell and will focus on analysis of the exhaled phage population in these samples. A central hypothesis is that bacteria involved in disease pathogenesis will be stressed and more likely to induce phage activation; we already know that phages are abundant in respiratory samples.
The work will be supported by the respiratory section of our NIHR Biomedical Research Centre and ongoing studies on COPD and asthma. The student will learn novel techniques in aerobiology, metagenomics and phage biology as well as key aspects of working with patients (ethics, consent and study power assessment).
Interviews will be held 17th May 2019
