Abstract

Clostridium difficile has become the most common cause of hospital acquired diarrhea after antibiotic treatment. The aim of this study was to determine the frequency of C. difficile associated diarrhea among hematology/oncology ward patients and to characterize isolated strains. Twenty three toxigenic and thirteen non-toxigenic strains were detected among fecal isolates. Antibiotic susceptibility testing to erythromycin and clindamycin demonstrated a high degree of resistance (MIC > 256 ug/ml) to both antibiotics in 9 out of 13 nontoxigenic C. difficle strains. Out of 7 patients with maximal frequency of diarrhea (10 empties/day) in 4 cases non-toxigenic strains of C. difficile were isolated. In these cases duration of diarrhea was longer in time than in cases of diarrhea caused by toxigenic strains. Further investigation with a larger patient population is necessary to better understand the role that non-toxigenic C. difficile strains play in disease development.
