Dear colleagues,

Sensitivity testing of pathogens in our laboratory is carried out in accordance with the rules and regulations of the clinical & laboratory standards institute (CLSI). Here, changes were recently made to the testing of enterobacteria and pseudomonas aeruginosa, which were implemented by us as of 1st April 2019. In more detail, the minimum inhibition concentration (MIC) for the testing of ciprofloxacin and levofloxacin was reduced.

This change may have an impact on your therapeutic considerations on the one hand; on the other hand, more strains could be classified as 3MRGN in future. Further information can be found in the original tables as below:

Please do not hesitate to contact us, if you have any further queries.
