From February 1990 until late October 1991, M. xenopi was isolated from the sputa of 30 persons in one of the 4 boroughs of Ostrava. This species could also be identified in water samples and smears taken in 7 out of 14 tested households of both colonized persons and patients with mycobacteriosis xenopi. As established, the optimum conditions for multiplication of M. xenopi exist in exchanger units; control measures for this agent in the exchanger facilities are proposed.
