The opportunistic pathogen Nocardia farcinica is a foam-producing bacterium in activated sludge plants.
A Gram-positive unicellular coccal-diphtheroid rod causing foam in an activated sludge plant was successfully isolated by micromanipulation. Phenotypic characterization and 16S rDNA sequencing identified it as Nocardia farcinica. This is the first report that this opportunistic pathogen is a foam-causing bacterium in activated sludge, and the clinical implications of these observations are discussed.
