[Bacteriostatic and bacteriacidal activity of hydroxy-9 ellipticine in vitro]

9-Hydroxy-ellipticine shows a clear effect against bacterial development. This effect depends essentially upon the bacterial species. Two groups can be differentiated: Group I with resisting species composed by negative Gram Bacilli (Enterobacteria and Pseudomonas); Group II with sensitive species formed by Coccus, positive Gram Bacilli, Mycobacterium tuberculosis and Anaerobes.
