[Porphyrinsynthesis of Propionibacterium acnes in acne and seborrhea (author's transl)].

The porphyrin productions of P a.-strains, isolated on the one hand from inlfammatory acne lesions, on the other hand from sebaceous follicle filaments from 10 persons each were compared quantitatively and qualitatively, after the appropriate material had been pooled, With respect to the acne strains one could observe a somewhat increased porphyrin production as well as the discharging of a precentually greater portion of porphyrins to the surrounding material. When separated by TLC the acne material showed a more intense coproporphyrin band.
