Rapid detection of Salmonella enterica serovar Typhimurium DT104 strains by the polymerase chain reaction
Abstract
Article
[Background] Infection with Salmonella enterica is a major public health concern in developed countries, and multidrug-resistant strains have become increasingly prevalent. S. enterica serovar Typhimurium DT104 (DT104) strains are prevalent in livestock in Japan and include numerous strains of multidrug-resistant S. enterica. Epidemiological analysis of these strains is critical for both agriculture and public health; however, diagnostic tests for these strains have yielded inconsistent results [Results] We developed a rapid, simple, and inexpensive polymerase chain reaction test to detect multi-drug resistant DT104 strains. We designed primers specific to the prophage ST104 sequence encoded by DT104 strains and assessed the specificity of these primers by assaying a panel of 50 S. enterica isolates. Amplification products of the expected size were generated from the genomes of each of the DT104 strains; however, the ST104 primers failed to amplify products from non-DT104 strains of S. enterica serovar Typhimurium or other S. enterica serovars. Furthermore, a probe generated using the ST104 primers detected a restriction fragment encoding the ST104 region of DT104 by Southern hybridization. [Conclusions] The ST104 primers exhibit specificity to DT104 strains and are suitable for epidemiological applications.
