From CLSI to EUCAST, a necessary step in Spanish laboratories

Abstract The Spanish Antibiogram Committee (Comite Espanol del Antibiograma, COESANT) presents in this document a simple “roadmap” or decalogue of recommendations, with a view to facilitating the transition from the Clinical and Laboratory Standards Institute (CLSI) to the European Committee on Antimicrobial Susceptibility Testing (EUCAST) antimicrobial susceptibility testing regulations to the Clinical Microbiology Spanish laboratories that still use the CLSI guidelines. The objectives are to adapt the closer European regulations to the Spanish clinical and epidemiological reality and to fully implement the EUCAST recommendations in all microbiology laboratories in Spain.
