Abstract:
A simple microplate method, based on conversion of tetrazolium to formazan, was devised for rapidly assessing Salmonella survival after phage treatment. Results were easily interpretable. Monitoring with a microplate reader was useful, but not required. The method was used in defining phage-Salmonella interactions for selection of phage biocontrol cocktails.
