Genomic DNA patterns generated by pulsed-field gel electrophoresis are highly specific for different strains of an organism and have significant value in epidemiologic investigations of infectious-disease outbreaks. Unfortunately, time-consuming and tedious specimen processing is an inherent problem which limits the use of this powerful technology as a real-time epidemic investigational tool. Here, I describe a rapid method to improve the response time and provide specific bacterial strain identification for the typing of Escherichia coli O157:H7 and other gram-negative organisms in a single day.
