Implementation of Salmonella serotype determination using pulsed-field gel electrophoresis in a state public health laboratory

We examined the use of pulsed-field gel electrophoresis (PFGE) to predict serotype for Salmonella isolates. Between 2012 and 2014 we assessed 4481 isolates, resulting in >90% assigned serotypes. PFGE is efficient for determining serotype in the majority of cases and results in expedited serotype determination, as well as cost savings.
