[Isolation of "Neisseria elongata" and "Moraxella urethralis" (author's transl)]

A strain of Neisseria elongata and a strain of Moraxella urethralis have been recently isolated from pathological material in the course of a systematic search for rodshaped oxidase positive and Gram negative micro-organisms. The morphological, cultural and biochemical characters of these fewly known strains of which pathogenicity is not clearly defined, are reported in the present paper together with some comments.
