The International Committee on Systematic Bacteriology held meetings in 1974 to discuss the taxonomy and classification of bacteria. The first meeting, on 26 September 1974, was attended by members of the Subcommittee on the Phage-Typing of Staphylococci. The meeting was called to order by R. Skalova, who was acting chairman. The minutes of the previous meeting were reviewed, and the membership and officers were discussed. The Subcommittee recommended continuing the 6th comparative typing test. They also discussed the composition of the medium for phage typing, noting the difficulty in obtaining agar and the need for a standardized medium. The Subcommittee evaluated seven experimental phages, finding three useful for typing untypable strains and recommending their addition to the basic set. They also decided to remove two less useful phages from the basic set. The Subcommittee also discussed the use of phages at different concentrations and recommended using a single concentration for typing. The use of experimental phages was also discussed, with the decision to allow their use without retesting with basic-set phages. The second meeting, on 23 and 25 September 1974, was held by the Subcommittee on the Taxonomy of Listeria and Related Bacteria. The meeting was called to order by H. J. Welshimer. The Subcommittee discussed proposed species names for the genus Listeria, minimal standards for examination and identification, and other related taxa. They also discussed the composition of the Committee and liaison with other subcommittees. The Subcommittee also discussed methods for identifying Listeria and related bacteria and planned the next meeting in 1977. The meetings were attended by various members and observers, and the minutes were recorded by the secretary.The International Committee on Systematic Bacteriology held meetings in 1974 to discuss the taxonomy and classification of bacteria.
