Data set containing reference data to interpret MIC and disk diffusion to R/SI values, according to international guidelines. Currently implemented guidelines are EUCAST (2011-2022) and CLSI (2011-2022). Use as.rsi() to transform MICs or disks measurements to R/SI values.




A tibble with 20,369 observations and 11 variables:

  • guideline
    Name of the guideline

  • method
    Either "DISK" or "MIC"

  • site
    Body site, e.g. "Oral" or "Respiratory"

  • mo
    Microbial ID, see

  • rank_index
    Taxonomic rank index of mo from 1 (subspecies/infraspecies) to 5 (unknown microorganism)

  • ab
    Antibiotic ID, see as.ab()

  • ref_tbl
    Info about where the guideline rule can be found

  • disk_dose
    Dose of the used disk diffusion method

  • breakpoint_S
    Lowest MIC value or highest number of millimetres that leads to "S"

  • breakpoint_R
    Highest MIC value or lowest number of millimetres that leads to "R"

  • uti
    A logical value (TRUE/FALSE) to indicate whether the rule applies to a urinary tract infection (UTI)


Like all data sets in this package, this data set is publicly available for download in the following formats: R, MS Excel, Apache Feather, Apache Parquet, SPSS, SAS, and Stata. Please visit our website for the download links. The actual files are of course available on our GitHub repository.

They allow for machine reading EUCAST and CLSI guidelines, which is almost impossible with the MS Excel and PDF files distributed by EUCAST and CLSI.
