| Abstract |
Vibrio vulnificus is found in marine waters near the coast around the world. Infection with this gram-negative rod, via ingestion of raw seafood or via a skin wound following contact with contaminated estuarine or marine water, can cause necrotizing fasciitis and sepsis. Most of patients with Vibrio vulnificus infection have underlying liver dysfunction or diabetes mellitus. Due to the high mortality and short latent periods, control of this infection depends on early identification of the bacterial species and prompt initiation of intensive care. Accordingly, the development of a technique that can identify this microbe quickly and accurately is of great importance. Loop-mediated isothermal amplification (LAMP) is a novel nucleic acid amplification method to detect specific genes with rapidity and high sensitivity. In this study, we developed LAMP for the detection of Vibrio vulnificus. Using 28 Vibrio vulnificus strains and 53 other bacterial strains, we confirmed the high specificity of this method. Moreover, our LAMP method also showed high sensitivity, with a minimum detection level of one colony-forming unit per test. Furthermore, we developed simplified and conventional pretreatments for the method using experimental animal models. All of these attempts have lod to our non being able to detect Vibrio vulnificus within 1 hour.
