Research Interests

Dr Mary Hanson is a Consultant Microbiologist within NHS Lothian and the Director of the Scottish E coli O157/STEC Reference Laboratory (SERL).

E coli O157 and other Shiga toxin- producing E coli (STEC) cause haemorrhagic colitis which may result in Haemolytic Uraemic Syndrome and other potentially fatal complications. New laboratory technologies, including whole genome sequencing of STEC organisms, have the potential to optimize timely clinical management of cases, and public health interventions to reduce transmission and prevent outbreaks. At the SERL, we are engaged in research to underpin the use of sequencing in the detection of clusters and outbreaks of infection, and to elucidate the sources of infection in food, water and the environment, with the aim of reducing the burden of disease in Scotland. We have strong research links with veterinary colleagues in the University of Edinburgh and with epidemiology and Public Health colleagues at Health Protection Scotland.

Research on bloodstream infection with Candida sp (candidaemia): Candidaemia is predominantly a healthcare associated infection and the incidence is high in Scotland compared with reported incidence rates in England and Wales. Attributable mortality is also high (>30%) and the infection occurs in a wide spectrum of patient groups. Our research has provided valuable information on the epidemiology and risk factors for candidaemia in patients with a variety of debilitating conditions, and supports the development of clinical strategies for prevention and treatment of these serious infections.
