All 238 Clostridium difficile isolates were susceptible to metronidazole and vancomycin, whereas 84% and 1% were resistant to clindamycin and fusidic acid. Etest MICs for metronidazole were lower than agar dilution MICs (P < 0.01) but without difference in susceptible-intermediate-resistant categorization. No particular PCR ribotype was associated with clindamycin or fusidic acid resistance.

Inno4Vac, a public-private partnership funded by the IMI2/EU/EFPIA Joint Undertaking (IMI2 JU), brings together academic institutions, SMEs, and pharmaceutical companies to accelerate and de-risk vaccine development. The project has made significant strides in the selection and production of challenge agents for influenza, respiratory syncytial virus (RSV), and toxigenic Clostridioides difficile for controlled human infection model studies (CHIMs). A regulatory workshop held on March 20, 2024, addressed the standardisation of clinical procedures, ethical considerations, endpoints, and data integrity, highlighting the ongoing initiatives related to these CHIMs.

Introduction: The infections of multidrug-resistant organisms (MDROs) associated with duodenoscopes during endoscopic retrograde cholangiopancreatography (ERCP) procedure have become a significant cause for concern, especially in fragile patients. While the clinical impacts of these infections are well-documented, their economic implications remain underexplored. This study assesses the incidence and economic burden of post-ERCP infections in Italy using an administrative database.

Recurrent Clostridioides difficile infection (rCDI) is a major cause of increased morbidity, mortality, and healthcare costs. Fecal-microbiota-based therapies are recommended for rCDI on completion of standard-of-care (SoC) antibiotics to prevent further recurrence: these therapies include conventional fecal-microbiota transplantation and the US Food and Drug Administration-approved therapies REBYOTA® (RBL) and VOWST Oral Spores™ (VOS). As an alternative to microbiota-based therapies, bezlotoxumab, a monoclonal antibody, is used as adjuvant to SoC antibiotics to prevent rCDI.

Clostridioides difficile (C. difficile) infection (CDI) is common after antibiotic exposure and presents significant morbidity, mortality and healthcare costs worldwide. The rising incidence of recurrent CDI, driven by hypervirulent strains, widespread antibiotic use and increased community transmission, has led to an urgent need for novel therapeutic strategies.
