title: Rapid lysis technique for mycobacterial species.
abstract: The lysis of mycobacterial cells typically has been difficult and time-consuming. We report a method for the physical rupture of Mycobacterium paratuberculosis and several other members of the family Mycobacteriaceae using a Mini-Beadbeater cell disrupter (Biospec Products; Bartlesville, Okla.) and zirconium beads, a process which yields DNA and RNA of high molecular weight and in greater quantity than that obtained by rupture in a Ribi pressure cell.
