Mycobacterium avium in a shower linked to pulmonary disease

Abstract

Mycobacterium avium was isolated from hot and cold water samples and from sediment (biofilm) collected from the showerhead in the home of a woman with M. avium pulmonary disease lacking known M. avium, risk factors. IS1245/IS1311 DNA fingerprinting demonstrated that M. avium isolates from the hot and cold water and showerhead sediment demonstrated a clonal relationship with the patient's M. avium, isolate. The data provide evidence that showers may serve as sources of infection by waterborne M. avium. © IWA Publishing 2008.
