The epidemiology of UTI and antibiotic resistant uropathogens
Urinary tract infections (UTIs) are very common, and antibiotics are almost always prescribed for them. Exposure to antibiotics increases the risks of developing infections with bacteria which are resistant to antibiotics in the future, but untreated UTIs can develop into more serious infections requiring hospital admission. We currently do not understand the link between taking antibiotics, and developing resistant urinary tract infections, and we also do not have a way of advising women whether they are likely to have a long or short duration of symptoms. The CONDUCT trial recruited 1200 women who came to see their GP with symptoms or urinary tract infection. A detailed medical and antibiotic usage history was taken and extensive microbiological tests were performed on samples. This doctoral opportunity will use this dataset to answer the following questions:
- Which patient factors (including age, sexual behaviours, comorbidities, frequency of previous UTI) are associated with longer durations of symptoms or more severe symptoms?
- What is the association between antibiotic usage in the 5 years prior and patterns of sensitivity and resistance to antibiotics on urine culture?
- Using the frozen cultures from these infections, can we use whole genome sequencing to identify genetic markers of resistance which are associated with a history of antibiotic usage and markers of virulence which are associated with UTI severity or frequency?
