Aims and objectives

The ESCMID Study Group for Epidemiological Markers (ESGEM) is at the centre of understanding microbial epidemiology within our Society. Typing is vital for microbial surveillance, from hospitals to global epidemiology. Recent advancements in molecular typing have expanded surveillance capabilities dramatically, sparking innovation. However, challenges persist, including the need for real-time, actionable data and integration with other data types. Standardised platforms and nomenclatures are essential, as is understanding microbial evolution and resistance traits. As global collaboration among scientists is crucial for standardisation and tracking pathogen spread, ESGEM is dedicated to: 

  • Reviewing the current microbial typing methods and providing recommendations for their appropriate use.
  • Encouraging and supporting collaborative research between scientists that fosters the development, implementation, and evaluation of microbial typing and epidemiology systems.
  • Promoting the education of young scientists on the most recent developments on microbial typing and epidemiology.
