 Amplification of ITS followed by "Fok"1 digestion results in an RFLP with a major product of 213 base-pairs for both "M. ulcerans" and "M. marinum", and a product band of 266 base-pairs for "M. liflandii".The following additional comparative differences were also used to identify "M. liflandii" KT1.1) KT1 is identical to "M. ulcerans" in the 5' signature region of RNA Polymerase subunit B ("rpo"B) and one base-pair off from "M. ulcerans" in the 3' region.
