AN EVALUATION OF CERTAIN SALMONELLA DETECTION METHODS IN SURFACE-WATER

Two different procedures were employed for detecting Salmonella spp. i n environmental water samples: a rapid method (enrichment in Salmosyst Broth and plating in Rambach Agar - Merck) and a longer assay (pre-en richment in Buffered Peptone Water, enrichment in Selenite-Cistyne Bro th and plating in Brilliant Green Agar -Difco). The efficiency of micr obiological rests was measured by the following criteria: recover, sen sitivity and specificity. The results analysed by the Kendall concorda nce coefficients demonstrated that the rapid method appeared more effe ctive even if poorly specific.
