Growth of on human serum albumin triggers programmed cell death.

Aims: Gingival crevicular fluid (GCF) constitutes the primary growth substrate for . The goal of this work was to evaluate the growth of different strains of on human serum albumin (HSA), a major constituent of GCF.

Methods: Growth of five different strains of in the HSA medium was examined and, surprisingly, three of the strains underwent autolysis within 24 h.
