OBJECTIVE: To determine the frequency with which Clostridium difficile was detected in stool specimens from outpatients and patients hospitalized for less than 4 days to assess the usefulness of routine laboratory screening for detecting this enteric pathogen. METHODS: Seven hundred and forty-one specimens from 398 patients were cultured over a 6-month period for Salmonella, Shigella, Yersinia, Escherichia coli O157:H7, Campylobacter and Clostridium difficile. Clostridium difficile culture-positive samples were further tested for cytotoxin production. RESULTS: Campylobacter, Salmonella, Shigella and E. coli O157:H7 were isolated in 50 (6.7%) specimens from 35 (8.8%) patients. Clostridium difficile was cultured from 88 (11.9%) specimens from 35 (8.8%) patients and its cytotoxin detected in 35 (4.7%) specimens of 12 (3%) patients. Clostridium difficile was the second most frequent enteric pathogen after Campylobacter. Of 178 (24%) specimens submitted with a specific request for Clostridi
