Abstract

Abstract Background Clostridium difficile infection (CDI) is a major cause of antibiotic-associated diarrhoea. Given an increasing CDI incidence and global spread of epidemic ribotypes, a 1-year study was performed to analyse the molecular characteristics ofC. difficile isolates and associated clinical outcomes from patients diagnosed with CDI in the Internal Medicine department at University Hospital Motol, Prague from February 2013 to February 2014. Results A total of 85 unformed stool samples were analysed and CDI was laboratory confirmed in 30 patients (6.8 CDI cases per 10, 000 patient bed days and 50.6 CDI cases per 10, 000 admissions). The CDI recurrence rate within 3 months of treatment discontinuation was 13.3% (4/30). Mortality within 3 months after first CDI episode was 26.7% (8/30), with CDI the cause of death in two cases. 51.9% ofC. difficile isolates belonged to PCR-ribotype 176. MLVA of ribotype 176 isolates revealed two clonal complexes formed by 10/14 isolates. ATLAS scores and Horn's index were higher in patients with ribotype 176 infections than with non-ribotype 176 infections. Conclusion This study highlights the clinical relevance ofC. difficile PCR-ribotype 176 and its capacity to spread within a healthcare facility.
