Instruction videos


In collaboration with the World Health Organisation (WHO), EUCAST publishes instruction videos on how to perform antimicrobial susceptibility testing (AST) using EUCAST recommended methods and interpretation. 


The videos are published on Youtube™ and have an English speaker voice and English subtitles. Since not all countries may access Youtube™ videos in some languages are made available directly on the EUCAST web page.  


Information added 2014-01-01: In some of the informational videos colleagues are advised to categorise the susceptibility of bacteria without breakpoints using the PK/PD breakpoints (previously available from the EUCAST breakpoint tables). This is no longer acceptable since the current opinion is that the PK/PD cut-off values may vary between species and EUCAST has therefore removed the PK/PD tab from the breakpoint table 14.0 (1 January, 2024). Instead we refer the EUCAST user to the guidance document “When there are no breakpoints” among the guidance documents.


The videos cover the following topics:


  1. Preparation of inoculum (English).
  2. Inoculation of agar plates for disk diffusion (English).
  3. Application of antibiotic disks and incubation of plates (English).
  4. Reading of inhibition zone diameters (English).
  5. Guidance on the use of the breakpoint table (English). See comment above added 2024.
  6. Storage and handling of media and disks (English) - subtitles in other languages pending.
  7. Quality control of AST in clinical microbiology (English) - subtitles in other languages pending.
