About this Webinar
13:00 - 14:00, Wednesday 24th April 2024

Chair: Dr Susanne Surman- Lee HonFRSPH Director, Leegionella Ltd

Speakers: Diane Lindsay Principal Clinical Scientist, Glasgow Reference Laboratories and Dr Susanne Surman- Lee HonFRSPH Director, Leegionella Ltd

Legionella pneumophila was identified as the causative agent of Legionnaires’ disease nearly 50 years ago. Since then, research and case investigations have progressed our understanding of the disease but there are still significant gaps in our knowledge and capabilities which may hamper our ability to detect infection and control sources.

This one hour free online webinar is a back-to-basics summary of legionella and the importance of the methods used to detect it. Dr Surman- Lee will touch on the origins of Legionnaires' disease and why it is still a problem (including rising cases), plus some UK and international guidance around its control. Diane Lindsay will discuss in more detail the methods used for detecting legionella in water systems, what the results and outcomes of these methods may mean, and what to consider when selecting appropriate testing.

Join online for an informative and interactive review of this very serious waterborne disease.


Dr Diane Lindsay PhD, Principal Clinical Scientist, Glasgow Reference Laboratories 

Dr Lindsay has over 30 years’ worth of experience of working on Legionella including the microbiological and molecular diagnosis of L. pneumophila and in particularly the clinical significance of non-pneumophila Legionella species including L. longbeachae.

She works closely with public health colleagues, epidemiologists and water laboratories and has been involved in many outbreak investigations. She is a member of the European study group on Legionella Infections (ESGLI) and has published widely in the field on a range of subjects in collaboration with ESGLI and academic colleagues. Dr Lindsay was previously a member of the ELDSnet (European Legionnaires’ disease surveillance network) executive committee and is currently secretary of the ESGLI executive committee.

She also has other areas of research interest including vaccine preventable bacterial diseases namely meningococci, pneumococci, H. influenzae, B pertussis as well as Group A and B Streptococci.

She is a former Director of the HPA (now Public Health England) London Food Water and Environmental Microbiology Laboratory and now Director and Co-owner of Leegionella Ltd.; an independent public health consultancy recognized internationally and nationally for its expertise in the detection of waterborne pathogens and prevention of waterborne disease by the development and implementation of water safety plans..  She has experience of investigating cases, outbreaks and incidents of gross contamination in over 50 healthcare premises nationally and internationally which has given her a unique insight into the root cause of the problems associated with poor design, specification, installation, commissioning and operation of water systems. 

Susanne has also organised many conferences on water quality management with the Royal Society for Public Health and is the Programme Director for the RSPH Water Webinar Series and Chair of the RSPH Water Special Interest Group.  For almost 20 years she has been involved with the development of national and international guidelines including; the World Health Organisation publications Legionella and the Prevention of legionellosis and Water Safety in Buildings,  the HSE publications, L8, HSG 274, HSG 282, HSG 179, the Department of Health’s HTM 04-01, and many British standards including  BS 7592, BS 8580-1 BS 8680 :2020 water quality ;water safety code of practice and is the current chair of the panel BSI panel writing BS 8580-2 Water Quality risk assessment for Pseudomonas aeruginosa and other waterborne pathogens. She was also chair of the ESCMID Study group for Legionella Infections (ESGLI) working group which produced the Technical Guidelines for the prevention, control and investigation of infections caused by Legionella and Guidance for managing building water systems, including in healthcare, in the time of COVID.
