Levofloxacin: reducing the risk of Pseudomonas aeruginosa resistance

Project Description

Many people with cystic fibrosis (PWCF) are chronically infected with Pseudomonas aeruginosa (Pa). Pa causes an accelerated decline in lung function, reduced quality of life and chest infections. Therefore, suppressive long-term treatment with inhaled antibiotics that target Pa is the standard of care; however, the optimal treatment strategy is not clear (e.g. continuous, intermittent or cycling with other inhaled antibiotics). Furthermore, the emergence of antibiotic resistant strains is a significant concern, especially as PWCF are living longer. In addition, sub-optimal adherence to treatments has been reported in CF, which may also potentially contribute to the development of antibiotic resistance.

This proposal will provide novel data on reducing the risk of Pa developing antibiotic resistance. This will be achieved by determining if and how resistance develops following in vitro exposure to levofloxacin and if antibiotic cycling selects for or against resistant Pa sub-populations. This proposal will also investigate if reduced exposure to levofloxacin, as a proxy for poor adherence, drives levofloxacin resistance development. This will provide evidence on the importance of adherence to chronic treatments to reduce the burden of antibiotic resistance.


Candidates should have or expect to obtain a 2:1 or higher Honours degree or equivalent in a relevant biomedical or life sciences subject.
