title: Rapid screening of Salmonella species from stool cultures.
abstract: The authors compared a three-minute fluorescence method (MUCAP test; Biolife Italiana, Milan, Italy) with standard microbiologic procedures for the presumptive identification of Salmonella from stool cultures on three solid culture media. From 976 suspect colonies, 176 proved to be Salmonella by the traditional methods. They all were detected by the MUCAP test (sensitivity, 100%). There were 65 false-positive results, corresponding mostly to Pseudomonas (specificity, 91.8%). Neither the culture medium used nor the production of H2S affected the accuracy of the test. The results from this study showed that the MUCAP test is a rapid, simple, and sensitive method for the presumptive identification of Salmonella species.
