The gut microbiome plays a crucial role in determining health and wellbeing, influencing the development of the immune system and its interactions with pathogenic microbes. Changes in the microbiome can significantly alter health status and contribute to the development of intestinal infection, with an altered microbiome being found to confer resistance to or promote infection by pathogenic bacteria. 

The worldwide occurrence of antimicrobial resistance coupled with the lack of new antimicrobials, is not only jeopardising our ability to treat infectious diseases but also undermining significant breakthrough advances in health and medicine. It is known that antibiotics have a profound impact on the microbiome and can lead to the expansion of pathogenic populations. 

With the emergence of antibiotic-resistance and the decreasing effectiveness of antimicrobials, the gut microbiome represents an important resource for new antimicrobials or bioactives which directly target pathogens or strengthen mucosal immune defences. Indeed, the microbiome is an important platform in which to identify effector organisms and postbiotics, including microbe-derived molecules and metabolites, as new therapeutic opportunities to treat infectious diseases. 

This meeting will provide insights into the current state of research in the field, offering opportunities for collaboration and to foster new ideas.

Key topics

  • Gut Microbiome in health and disease
  • Antimicrobial resistance in bacteria
  • New sources of antimicrobials
  • Bioactives including effector organisms, probiotics and postbiotics

COVID-19 Mitigations

As part of the preparations for returning to delivering in-person events, Microbiology Society Council members and members of the Virus Division have worked with Society staff to develop a framework of mitigations for the Society to apply to all of its events throughout 2022, in order to ensure that these are as COVID-secure as possible.

Implementation of this framework is a shared responsibility; shared between the Society, the venues we use for our events, and all potential attendees. Attendance at any of our events is a personal choice, but it will be incumbent on all of us to deliver these mitigations in order for us to keep all delegates and staff as safe as we can.

The framework covers the following five areas.

1. Vaccines
2. Ventilation
3. Masks
4. Testing
5. Spacing, particularly during communal activities such as lunch and poster sessions

The following mitigations will be implemented for all those attending a Focused Meeting in 2022. The Society staff will continue to consult with the organising committee in the lead up to the event and these mitigations will be kept under review and may be amended to ensure they remain appropriate as circumstances change.

Mitigation area


All attendees are required to be fully vaccinated with an approved vaccine against COVID-19 to attend a Focused Meeting in 2022. For many individuals, this will mean a primary course and booster vaccine, and with the booster administered at least 14 days before the meeting. However, if you do not meet this requirement or if you have any concerns around your vaccination status, please get in touch with us to discuss it further by emailing [email protected]

You can find further information on vaccines on the World Health Organization (WHO) COVID-19 vaccine advice page, which includes a list of vaccines that have been approved for use against COVID-19.


Best efforts will be made to promote the circulation of fresh air into each Focused Meeting venue. This will include use of air conditioning, if available at the meeting venue, or opening of doors and windows during appropriate intervals in the event programme if possible.


FFP3 masks will be provided to all individuals attending a Focused Meeting in 2022 and everyone will be expected to wear them inside the meeting venue, except when eating or drinking and except for those that have medical exemptions.


Attendees will be provided with LFT devices and are expected to test themselves daily before entering the meeting venue.


All attendees are reminded to adhere to social distancing where possible, particularly during communal activities such as lunch and poster sessions.

Further information will be announced in the build up to the meeting on our social media channels and you can follow us on Twitter @MicrobioSoc using the hashtag #MiningMicrobiome22



The meeting will consist of one full day on 27 October and a half day on 28 October. There will be a dedicated poster session on 27 October. Further programme information will be available shortly.


Details of registration for the event will be announced shortly.


We are aware of ongoing uncertainty around event attendance as the pandemic continues. In order to give delegates the most confidence and flexibility, we will refund all registration fees in full if you cancel your booking, for whatever reason, at any time in the lead up to the event. If you wish to cancel your booking and request a refund before the event, please email [email protected]

Abstracts & Posters

Abstract submissions for Gut Microbiome and Mucosa-Associated Infectious Disease: Mining for Antimicrobials and Postbiotics with Therapeutic Potential are now open. 

Submissions close on 15 August 2022, 23:59 BST.

Submit your abstract


Both members and non-members of the Microbiology Society are welcome to submit an abstract for the meeting. All offered oral and poster presentations will be selected from the abstracts submitted. Once submissions are closed, they will be reviewed by the organising committee, and submitters will be notified of the outcome by email.

By submitting an abstract to this meeting, you are indicating to the session organisers your commitment to attend the event in-person.

Abstract guidance

Abstracts must be a maximum of 250 words. The Society has produced a guide to give delegates some tips on how to write a great abstract, which can be downloaded below:

How to write a great abstract


Please note that the abstract is the only information session organisers use when deciding whether to accept your work for presentation as an offered oral or poster. If accepted, it will also be published in the abstract book for the meeting, so think carefully about what needs to be included.

Grants and Professional Development

Information on grants to support attendance at this meeting will be available shortly.
