The newly described cause of a mycobacteriosis in Chesapeake Bay (USA) striped bass (Morone saxatilis) was equated to a new species, M. shottsii, with confirmation by 16S rRNA sequence homology in which the pathogen was linked most closely to M. marinum and M. ulcerans (similarity = 99.2%). In one study, M. gordonae was identified by 16S rRNA sequencing
