Aims and objectives

The ESCMID Study Group for Mycoplasma and Chlamydia Infections (ESGMAC) gathers physicians, veterinarians, microbiologists, and scientists. Together, they are dedicated to improving the understanding of clinical presentation and epidemiology (including antimicrobial resistance) of Mycoplasma, Ureaplasma, and Chlamydiales infections in both humans and animals. Their collaborative mission aims to:

  • Define the clinical presentation of infections from various Mycoplasma and Ureaplasma genus, as well as those classified within the Chlamydiae phylum, both in humans and in animals
  • Study the epidemiology of Mycoplasma and Chlamydiae infections and the transmission modes of new chlamydia-related bacteria
  • Improve diagnostic tools for challenging-to-culture Mycoplasma and Chlamydiae, which are better detected by molecular assays
  • Develop genomics capacity to better understand the biology of Chlamydiae and Mycoplasma, while providing sequences needed for molecular epidemiology
  • Identify new drug targets and refine treatment protocols and duration for the large diversity of infections due to Chlamydiae and Mycoplasma, from very common and easy-to-treat infections like chlamydial urethritis to rare but serious cases such as Mycoplasma hominis endocarditis
  • Understand the evolution of Chlamydiae phylum’s mollicutes
  • Engage with active collaboration with relevant international scientific societies such as the International Organization for Mycoplasmology (IOM), the European Society for Chlamydia research (ESCR) and the European Society for Chlamydioses, Coxiellosis, Anaplasmosis, Rickettsioses and Bartonellosis (ESCCAR)

Activities and resources

ESGMAC Early Career Mycoplasma and Chlamydia Researcher Conference 2025 (ECMCR 2025)

On 19th of February 2025, the third ECMCR - a Young Investigator Day will be organised. It has been designed to give early career researchers an opportunity to present their research on Chlamydia and Mycoplasma in a low-pressure and welcoming environment, as well as to build on their presentation skills. It will also serve to highlight career development opportunities in this field. Finally, we have one or two invited speakers who will give an overview lecture and provide insight in making the most out of your research career. To promote participation from early career researchers, registration for this conference is FREE. 

The meeting will be held online, with presentations from selected abstracts during the day. 

Abstracts on all aspects of mycoplasma and chlamydia biology and diagnostics with relation to human health and disease are welcomed! The submitted work may encompass clinical presentation, epidemiology, development and mechanisms of antimicrobial resistance in relation to Mycoplasma, Ureaplasma and Chlamydia infections in humans, as well as advances in diagnosis, treatment, control and prevention of these infectious diseases.

Instructions for abstracts are identical to those for ESCMID Global: Structured body text of maximal 350 words and 1 to 3 Figures or tables.

There will be awards for the best abstracts for the presenters.

Please send your abstract ultimately on 19th of January 2025 to the ESGMAC secretariat: Mirja Puolakkainen: mirja.puolakkainen(at)helsinki.fi.
