To compare the isolating efficiency of diarrhea-causing Escherichia coli between Fluorocult agar plates, which reveal the beta-glucuronidase activity of E. coli, and a combination of SS and DHL agar plates, a total of 330 fecal specimens collected from outpatients were examined. Diarrhea-causing E. coli, identified by serological and toxigenic characters, were demonstrated in 52 samples. Among these specimens, 35 samples tested were positive on the Fluorocult agar plates, and 26 samples on the combination of SS and DHL agar plates. However, only 10 samples were positive on both the Fluorocult agar plates and the combination of SS and DHL agar plates. Thus, using Fluorocult agar plates for the isolation of diarrhea-causing E. coli in addition to the conventional SS and DHL agar plates will improve isolating efficacy.
