∗The seven cases of coinfection included three cases of M. avium subsp. avium and M. intracellulare coinfection; one M. avium subsp. hominissuis and M. intracellulare coinfection; one M. intracellulare and M. kansasii coinfection; one MTB and M. intracellulare coinfection; and one MTB and M. massiliense coinfection.∗∗Three clinical isolates were not clearly identified by the first and second mPCR as well as multigene sequence-based analysis. ND, not determined.
