Development of a simple, rapid, and sensitive diagnostic assay for enterotoxigenic < i > E < /i > . < i > coli < /i > and < i > Shigella spp < /i > applicable to endemic countries

by Subhra Chakraborty, Sean Connor, Mirza Velagic EnterotoxigenicE.coli (ETEC) andShigella spp (Shigella) are complex pathogens. The diagnostic assays currently used to detect these pathogens are elaborate or complicated, which make them difficult to apply in resource poor settings where these diseases are endemic. The culture methods used to detect Shigella are not sensitive, and the methods used to detect ETEC are only available in a few research labs. To address this gap, we developed a rapid and simple diagnostic assay –"Rapid LAMP based Diagnostic Test (RLDT)." The six minutes sample preparation method directly from the fecal samples with lyophilized reaction strips and using established Loop-mediated Isothermal Amplification (LAMP) platform, ETEC [heat labile toxin (LT) and heat stable toxins (STh, and STp) ge nes] and Shigella (ipaH gene) detection was made simple, rapid (
