Royal Society of Chemistry seminar series - Microbiological diagnostics using volatile organic compounds

Thursday, December 6, 2018 17:00 - 18:00
Time Zone: Europe/London
Local Time: Thursday, December 6, 2018 17:00 - 18:00

‘Microbiological diagnostics using volatile organic compounds’ by John R Dean is the third in a series of Royal Society of Chemistry (RSC) seminars taking place at University of Sunderland. Tickets are free and bookable via eventbrite.

Current methods used to identify pathogenic bacteria used throughout clinical microbiology laboratories, particularly the more traditional methods such as culturing, are often time-consuming and often multiple methods are required to identify particular species. The analysis of volatile organic compounds (VOCs) generated by bacteria has been proposed as a possible alternative method in the identification of pathogenic bacteria.

Reports investigating bacterial VOCs have identified a number of VOCs as potential markers for specific pathogenic bacteria as well as whole VOC profiles than can act as a volatile “fingerprint”. Despite this, procedures followed for sample preparation and VOC collection and detection vary greatly between different research groups leading to variation in the VOC profiles reportedly generated by bacteria.

Currently no single VOC or a group of VOCs has been identified that is specific enough to characterise a particular species. This is demonstrated by the highly complicated profiles liberated by polymicrobial clinical and food samples.

Further investigations into the VOCs generated by many different species and strains of the same species are required alongside the use of consistent growth conditions and standardised procedures throughout VOC analysis.

Consequently the true potential of the detection of bacterial VOCs as a diagnostic tool in the identification of pathogenic bacteria in clinical and food samples has not been determined.

In this presentation John examines the issues with some interesting case studies.
