Elderly people are at increased risk for infections such as with Clostridium difficile. This can colonize their gut and cause various gastro-intestinal manifestations. Our survey investigated its prevalence in a nursing home in Iran. Faecal samples were collected and tested by polymerase chain reaction for identification of A, B and binary toxin genes. From 289 samples, 42(14.5%) isolates were found. Toxin genes were positive in 19 isolates (17 AþBþ and 2 isolates ABþ). The elderly are especially at risk and great attention should be paid to contamination within their nursing homes. This is not an isolated regional problem.
