Identification of Eikenella corrodens and Cardiobacterium hominis by genetic transformation

Genetic transformation was employed to attain exact identification of Eikenella corrodens and Cardiobacterium hominis. The two species appeared both homogeneous and without genetic affinity to each other or to species of Kingella, Neisseria, and Moraxella, as tested for by rather sensitive procedures with streptomycin- and spectinomycin-resistance markers.
