ESCMID Panorama

Medical Biofilm Techniques 2016, ESCMID Postgraduate Technical Workshop

22 - 25 August 2016, Lyngby, Denmark

Organizer
  • ESCMID Study Group for Biofilms (ESGB)
Course Coordinators
  • Thomas Bjarnsholt, Copenhagen, Denmark
  • Claus Sternberg, Lyngby, Denmark
Course Objectives

The course focuses on medical biofilms with examples from urinary tract infections, osteomyelitis, chronic wound and cystic fibrosis lung infections. The techniques include set-up and running of biofilm flow cell systems, fluorescence in situ hybridization, various advanced imaging techniques/analysis, and demonstrations of biofilm techniques in experimental animal research. There will be morning and late afternoon lectures. The rest of the day will be devoted to laboratory demonstrations and hands-on work.

Target Audience

Maximum 20 scientists (including clinical and basic research) with experience in laboratory training.

CME Accreditation

The organizers of the course will apply for European CME accreditation through EACCME.

08:30 Coffee
09:00 Welcome & introduction to medical biofilms: antibiotic resistance and medical importance in general. Thomas Bjarnsholt
10:00 Exercises, practical and technical information: biofilms and tools, confocal microscopy (Imaris image processing). Janus Haagensen, Kasper Kragh & Claus Sternberg
12:00 Lunch
13:00 Tour in the institute and practicals in the lab:

Biofilm system 1

E. coli, E. coli F+ traD mutant, image acquisition and COMSTAT (15 channel system, Media FB with Fe-EDTA + A-10. Addition of glucose, proline & thiamine). System assembled and sterilized.

Biofilm system 2
