All reference data (about microorganisms, antibiotics, R/SI interpretation, EUCAST rules, etc.) in this AMR package are reliable, up-to-date and freely available. We continually export our data sets to formats for use in R, SPSS, SAS, Stata and Excel. We also supply tab separated files that are machine-readable and suitable for input in any software program, such as laboratory information systems.

On this page, we explain how to download them and how the structure of the data sets look like.

If you are reading this page from within R, please visit our website, which is automatically updated with every code change.

Microorganisms (currently accepted names)

A data set with 70,760 rows and 16 columns, containing the following column names:
mo, fullname, kingdom, phylum, class, order, family, genus, species, subspecies, rank, ref, species_id, source, prevalence and snomed.

This data set is in R available as microorganisms, after you load the AMR package.

NOTE: The exported files for SAS, SPSS and Stata do not contain SNOMED codes, as their file size would exceed 100 MB; the file size limit of GitHub. Advice? Use R instead.
