 The strain of "M. liflandii" that has been isolated from anuran sources at the University of California, Berkeley, has been designated KT1.KT1 is characterized and differentiated from its closest relatives, "Mycobacterium ulcerans" and "Mycobacterium marinum", by the following molecular and physical traits.Restriction Fragment Length Polymorphism (RFLP) assay
KT1 has a three base-pair difference from "M. ulcerans" and "M. marinum" in its Internal Transcribed Spacer (ITS) that results in a lack of a "Fok"1 restriction enzyme site that is present in "M. ulcerans" and "M. marinum".
