[The detection of salmonellas using Rambach agar].

Selective enrichment in Rappaport-Vassiliadis medium of 1595 animal fed samples and of 82 feedstuff and carcass meal was streaked simultaneously onto water-blue-metachrome-yellow-lactose-agar acc. to Gassner, onto brilliant-green-phenol-red-lactose-agar acc. to Kauffmann and onto Rambach agar. Salmonellae were isolated in 34 cases with Rambach agar (sensitivity 94.4%), in 33 cases with water-blue-metachrome-yellow-lactose-agar acc. to Gassner (sensitivity 91.7%) and in 31 cases with brilliant-green-phenol-red-lactose-agar acc. to Kauffmann (sensitivity 86.1%). The high specificity (99.87%) recommends the use of Rambach agar for isolation of Salmonellae from selective enrichment.
