Techniques for the isolation of salmonellas from eggs.
1. When the contents of 4 or more naturally-contaminated intact eggs were combined, the isolation rate of Salmonella enteritidis was improved by extending incubation at 37 degrees C from 24 to 48 h before sub-culture. 2. The isolation rate of salmonellas from raw homogenised whole egg was significantly increased by the inclusion of Novobiocin and Cefsulodin in the primary culture media. 3. Rappaport Vassiliadis broth was found to be superior to Selenite as a selective enrichment medium.
