A Note on the Genus Aeromonas

Abstract

Previous workers have shown that the flagellation of certain bacteria is variable, becoming lateral or polar according to age and conditions of culture. In view of these findings, and because of the morphological and biochemical similarity of the organisms, Lysenko (1958) has equated Pseudomonas noctuarum with Serratia marcescens. It is now suggested that Pseudomonas noctuarum would be better placed in the genus Aeromonas, and that it is similar to an organism provisionally named A. margarita. It is further suggested that all members of the genus Aeromonas could be regarded as non-chromogenic species of the genus Serratia.
