The isolation and identification of a novel, slow-growing, scotochromogenic, mycobacterial species is reported. A strain, designated MUP 1182T, was isolated from a cervical lymph node of a 3-year-old child. MUP 1182T is alcohol- and acid-fast, with a lipid pattern that is consistent with those of species that belong to the genus Mycobacterium. It grows slowly at 25-37 °C, but does not grow at 42 °C. The isolate was revealed to be biochemically distinct from previously described mycobacterial species: it has urease and Tween hydrolysis activities and lacks nitrate reductase, 3-day arylsulfatase and β-glucosidase activities. Comparative 16S rDNA sequencing showed that isolate MUP 1182T represents a novel, slow-growing species that is related closely to Mycobacterium lentiflavum and Mycobacterium simiae. On the basis of these findings, the name Mycobacterium parmense sp. nov. is proposed, with MUP 1182T (=CIP 107385T = DSM 44553T) as the type strain.
