Project background
Antimicrobial resistance (AMR) is an unfolding public health emergency. In 2019 there were 4.95 million deaths associated with AMR1 (comparable with HIV and malaria) and by 2050 more people will die of AMR infections than cancer2. Research has focused on aquatic and soil environments, leaving the role that bioaerosols (airborne microorganisms) play in the proliferation of AMR unknown. Our preliminary data shows that AMR bacteria are ubiquitous in indoor and outdoor air. We found high incidence of beta-lactam resistant bioaerosols in outdoor air (e.g. near aquatic environments such as sewage outlets, and composting sites). It is critical that we understand the role of the environment in the dispersal of AMR microorganisms in the air. It is not possible to tackle this crisis in isolation, an integrated “One-Health” approach must be taken across healthcare, agriculture, and environment 3. However, the role of the environment and the basic ecology of bioaerosols (airborne fungi and bacteria) is poorly understood. Towards these ends, this project will investigate the diversity and emission of AMR across a range of environments. Project aims and objectives:
The student will collect bioaerosol samples from a range of environments and will also have access to samples collected on previous projects. They will be able to select the environments based on their own interests and the results as the project develops. They will screen the samples for AMR bioaerosols using culture-based methods and investigate the genetic underpinning of this resistance by developing PCR assays to detect key AMR genes. Again, the student will be given freedom to use their own initiative to select gene targets based on their own reading and intellectual curiosity. This project forms an off-shoot to a current EU Horizon funded project (InChildHealth, EU:10105688). The student will benefit from working in a well-funded lab with support from a post-doc and PhD student for lab and fieldwork, in addition to an experienced supervisory team (Dr Rob Ferguson, Dr Elizabeth Archer, and Prof Ian Colbeck). Aligning with the InChildHealth project will give access environments for sampling, ensure support in the field and lab, and enhance opportunity for career development. 1Murray, Christopher JL, et al. “Global burden of bacterial antimicrobial resistance in 2019: a systematic analysis.” The lancet 399.10325 (2022): 629-655.2O’Neill, Jim. “Tackling drug-resistant infections globally: final report and recommendations.” (2016).3Kim, Dae-Wi, and Chang-Jun Cha. “Antibiotic resistome from the One-Health perspective: understanding and controlling antimicrobial resistance transmission.” Experimental & molecular medicine 53.3 (2021): 301-309.
