Metabolism, Physiology, and Taxonomic Relationship of Gram-negative Cocci. A large number of as yet unclassified Gram-negative cocci are known to be associated with amimals and are also found in soil and water. Using a simple technique for genetic transformation, Dr. Juni and his co-workers have devised a method for establishing the genetic relatedness of bacteria in genera such as Acintobacter, Moraxella, and Neisseria. Current efforts in the laboratory are concerned with establishing new genera for Gram-negative cocci based largely on their genetic compatibility. Some of these bacteria appear to have unique physiological properties, and certain aspects of their metabolism and its regulation are under investigation.
