Comparison between semisolid Rappaport and modified semisolid Rappaport-Vassiliadis media for the isolation of Salmonella spp. from foods and feeds.

Two semisolid media poured in petri dishes, semisolid Rappaport and modified semisolid Rappaport Vassiliadis were compared for the recovery of Salmonella spp. from 154 high- and low-moisture foods and feeds. Semisolid media were inoculated after pre-enrichment in buffered peptone water and after enrichment in Müller-Kauffmann tetrathionate broth and selenite cystine broth.
