It was found that Vibrio comma phages absorbed on filter paper maintain their lytic property for a long period of time. A mixture of four phages covering a wide range of true cholera vibrios was prepared and absorbed on filter paper disks which were stored for 4 months. These disks proved helpful in the identification of V. comma.
