This is a self-funded, 3 year full-time or 6 year part-time PhD studentship. This project is supervised by Dr Sarah Fouch and Dr James Brown.

Antibiotics are a cornerstone of modern healthcare – but due to their low financial returns, there's a worrying lack of new antibiotics being developed.

The emergence of antibiotic-resistant bacteria has made the situation worse – and these bacterial strains are now recognised by the World Health Organisation as the greatest threat to mankind.

On this PhD, you'll be part of the solution. You'll explore how altering the composition of the bacteria causing the infection could have positive long-term affects, through faecal transplant.

The work will include:

  • Collecting microbial samples from patients suffering from resistant C.Diff infections, prior to and after a faecal transplant
  • Using molecular biology, microbiology and high performance chemical analyses to probe the changing nature of GI microbiota and to directly address any long-term deficits
  • Helping to prevent the onset of new infections and in doing so, provide a significant saving in patient and healthcare costs

By focusing on the regions of the body which are normally populated with micro-organisms – such as the intestine – it's possible to alter the behaviour and makeup of otherwise dangerous pathogens.

The human intestine harbours more than 1000 different species of bacteria which are essential for health. However, changes to this natural ecosystem alter the balance of healthy and pathogenic bacteria, with potentially devastating consequences – such as the life-threatening and difficult to treat infection Clostridium difficile (C.diff), which accounts for 2053 deaths in English and Welsh hospitals each year.

One successful treatment for severe infections like C.diff is faecal transplantation from healthy donors. This treatment repopulates the intestinal microbiota of a patient, rebalancing bacterial populations and curing the patient.

The success of this treatment is more than just theoretical: QA hospital has previously carried out two to three faecal transplants a month, saving around £10,000 in treatment costs per patient in addition to curing them.

But despite its success, we don't know what long term effects this treatment has on a patient's complex microbial community, as this is equally important for long-term health.

In collaboration with NHS services, this project will investigate the changes in the intestinal microbiota prior to and after faecal transplant procedures for C. diff, with the objective of determining the long-term changes in Gastro Intestinal (GI) microbiota, and the continued health and wellbeing of the patients.
