Abstract
A study was carried out to compare three rapid methods for detection of Salmonella spp. The fluorogenic MUCAP test (Biolife, Italy), the SM-ID agar test (bioMerieux, France) and the Rambach agar test (Merck, Germany) were used in this study to examine 103 strains (69 Salmonella strains and 34 non-Salmonella strains). Two conventional culture media, Hektoen and Leifson agars, were also included. The sensitivities of the MUCAP, SM-ID, Rambach and Hektoen agar tests for pure strains were 100, 93, 88 and 99%, respectively, and their specificities were 74, 97, 76 and 59%, respectively. A total of 100 stool samples from patients with acute diarrhoea was also tested and showed great discrepancy between the different methods. In agreement with other investigators, it was found that the discriminating capacity of Rambach and SM-ID as primary plating media was very restricted. The MUCAP test was very sensitive, rapid and easy to perform but not very specific. In view of these results, it is essential to combine different methods for the accurate and reliable detection of Salmonella strains.
