Clostridioides difficile (C. difficile) is a spore-forming anaerobic bacterium and the main cause of
nosocomial diarrhea, making it a global public health concern. This study focuses on evaluating
the resistance and susceptibility of the bacterium to various antibiotics. As part of a multicenter
project, strains isolated from patients in 9 hospitals in the Valencian Community and Andalucia
were analyzed. Antibiotic susceptibility tests were conducted to determine the minimum inhibitory
concentration (CMI) of antibiotics used both in the direct treatment of C. difficile infections and
those that promote its proliferation. The results were analyzed following the clinical and
epidemiological cutoff values (ECOFF) established by EUCAST and CLSI. Therapeutic
antibiotics such as fidaxomicin and vancomycin showed good activity against C. difficile, with low
resistance rates, highlighting fidaxomicin as the most effective option. Metronidazole remains
effective, but its use should be secondary due to potential adverse effects. Tigecycline showed
the lowest MIC; however, the lack of clinical cutoff values prevents an accurate assessment of its
resistance. In contrast, antibiotics not specifically targeting C. difficile showed higher MIC values
and higher resistance rates, especially ciprofloxacin and ceftriaxone, which could promote
intestinal dysbiosis and C. difficile development.
