Rapid identification of Salmonella enterica subsp. arizonae and S. enterica subsp. diarizonae by real-time polymerase chain reaction.

Reptiles are popular as pets, leading to an increased risk of human infections due to uncommon Salmonella strains including the Arizona group (subspecies arizonae and diarizonae). We present a real-time Arizona-specific polymerase chain reaction demonstrating 100% specificity and 99.6% sensitivity, offering savings in time and labor over traditional identification methods.
