  - Clostridium difficile is an increasing cause of nosocomial diarrhoea and colitis. The aim of this study was to identify the prevalence and characteristics of asymptomatic C. difficile carriage in a continuing care institution for the elderly. Stool samples were collected from 100 asymptomatic patients, whose median age was 83 years. Samples were tested for C. difficile using traditional culturing methods, 16s rDNA and 16s-23s intergenic spacer (IGS) rDNA sequencing, and analysed for toxin production and toxin genes. The prevalence of C. difficile carriage was 10/100 (10%) following culture and 16s and IGS sequencing. An additional seven isolates, initially identified as C. difficile, were subsequently identified by IGS rDNA sequencing as C. sordellii of the 10% that tested positive for C. difficile, seven tested positive for toxin A and B. A significant number of C. difficile carriers had recent antibiotic exposure compared with non-carriers, P = 0.046. The prevalence of asymptomatic C. difficile carriage in this institution was 10%, 7% of which were toxin positive. This study underscores the importance of increased vigilance for C. difficile using microbial and molecular methodology and identifies patients at increased risk following antibiotic administration.Clostridium difficile is an increasing cause of nosocomial diarrhoea and colitis.
