We report the case of a 46-year-old white male with confirmed Clostridium difficile infection for >4 weeks after fluoroquinolone therapy. The patient received two courses of metronidazole 500 mg three times daily (t.i.d.) during which time diarrhea resolved; however, symptoms recurred 14-15 days after treatment termination. He received a 2-week course of vancomycin 125 mg four times daily, with symptoms recurring 10 days after treatment conclusion. The patient then received a pulsed tapering schedule of vancomycin with adjunctive Saccharomyces boulardii. Diarrhea recurred 12 days after treatment completion. He received rifaximin 400 mg t.i.d. while hospitalized for diarrhea-associated complications. Symptoms resolved within 24 h. The patient received a 4-week regimen of rifaximin 400 mg orally t.i.d. after discharge. No further episodes of diarrhea were reported within 6 months after treatment termination. The present case supports the potential benefit of rifaximin for the treatment of recurrent Clostridium difficile infection.

Objectives: We aimed to describe the characteristics of Clostridioides difficile infection (CDI) in cancer patients, analysing risk factors for 90-day recurrence and attributable mortality.
Methods: Retrospective analysis on all CDI episodes from 2020 to 2022 in three Australian hospitals and one Spanish hospital. Logistic regression analyses were performed.

Treatment with antibiotics is a major risk factor for infection, likely due to depletion of the gastrointestinal microbiota. Two microbiota-mediated mechanisms thought to limit colonization include the conversion of conjugated primary bile salts into secondary bile salts toxic to growth and competition between the microbiota and for limiting nutrients. Using a continuous flow model that simulates the nutrient conditions of the distal colon, we investigated how treatment with 6 clinically used antibiotics influenced susceptibility to infection in 12 different microbial communities cultivated from healthy individuals.

As current antibiotic treatment failures and recurrence of infections are highly frequent, alternative strategies are needed for the treatment of this disease. This study explores the use of bacteriocins, specifically lacticin 3147 and pediocin PA-1, which have reported inhibitory activity against .

Clostridioides difficile, a spore-forming anaerobic bacterium, is the primary cause of hospital antibiotic-associated diarrhea. Key virulence factors, toxins A (TcdA) and B (TcdB), significantly contribute to C. difficile infection (CDI).
