Résumé : We report here that production and release of PGE2 do not occur in common bacteria. The apparent production in the presence of arachidonic acid, previously reported may be explained by PGE2 contamination and autooxidation of the AA used. The presenc of PGE2 like material in some but not all isolates of Propionibacterium acnes is confirmed.
