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:
ESGMAC Mycoplasma pneumoniae Surveillance (MAPS) study
Background
The aim of the ESGMAC MAPS study was to prospectively collect M. pneumoniae detection data from around the world following the COVID-19 pandemic and, where possible, to retain isolates and/or DNA from local sites for future typing to monitor and characterise the re-emergence of M. pneumoniae from a global perspective.
The ESGMAC MAPS study was able to observe the beginning of the re-emergence of M. pneumoniae infections in the second half of 2023 right before the global occurrence of pneumonia outbreaks and timely alert clinicians via monthly website updates. This allowed a prompt response with adequate management.
News
Our new publication reports the global spatiotemporal dynamics of the substantial M. pneumoniae re-emergence in late 2023 with data from 29 countries. To our knowledge, this study represents the largest combined dataset for M. pneumoniae detections. Additionally, this work provides detail of patient outcomes for several sites, information on macrolide resistance across the globe, and answers to why a substantial delay was seen in the re-emergence of M. pneumoniae compared with the re-emergence of other respiratory pathogens.
Ongoing projects
ESGMAC MAPS study update:
Re-emergence and beyond (2023-2025)
Data collection in progress, planned publication in summer 2025
ESGMAC MAPS subtyping study (ESCMID Study Group Collaboration Grant: ESGMAC, ESGEM, ESGMD):
Developing a novel method for assessing global genetic diversity and molecular surveillance of M. pneumoniae during its re-emergence after the COVID-19 pandemic and beyond
In progress
