Extract

The source of infection of a hospital-acquired Legionnaires' disease case was determined for the first time by nested polymerase chain reaction based on sequence-based typing. The typing was performed directly on DNA extracted from tissue samples, allowing a rapid epidemiological correlation with environmental isolates.
