Il est proposé de souligner, dans les formules de l’antigène O des Salmonella du schéma de K. W., les facteurs dont la présence est en corrélation avec celle d’un phage convertisseur, et de ne plus attribuer de noms aux variantes sérologiques caractérisées par la présence ou l’absence d’un de ces facteurs. Les noms correspondant à des variantes lysogénisées de sérotypes connus (par exemple ceux des groupes E2, E3, C4 - S. siegburg) pourraient être, en raison de leur importance épidémiologique, maintenus dans le schéma de K. W. bien que leur niveau taxonomique corresponde à celui de certains lysotypes de S. typhi ou S. paratyphi B.

More than 50 characteristics for each of 120 strains of Bacterium anitratum Schaub and Hauber 1948 were compared with the characteristics of the type strain of B. anitratum, American Type Culture Collection (ATCC) 19606, to explore the parameters of the strains. The incidence of each character among the 120 strains is expressed quantitatively. These strains of the species have a definite reproducible biochemical reaction pattern by which the species may be expediently recognized. B. anitratum is a validly published illegitimate name according to the International Code of Nomenclature of Bacteria. The oldestknown available legitimate name for this species appears to be Achromobacter anitratus (Schaub and Hauber) Bourlat 1953, 43. De Bord’s (1942) description of Herellea vaginicola does not fit any of the 120 strains of B. anitratum studied. Diplococcus mucosus von Lingelsheim 1906 and H. vaginicola are not senior synonyms for B. anitratum. The proposed neotype strain of Achromobacter mucosus, the type strains of A. conjunctivae, and A. haemolyticus subsp. haemolyticus are identified as strains of B. anitratum. None of these 3 names is a senior synonym of B. anitratum.

American Type Culture Collection (ATCC) strain 14990 has been proposed (Hugh and Ellis 1967) as the neotype strain for Staphylococcus epidermidis (Winslow and Winslow 1908) Evans 1916. The characteristics of this strain are presented and compared to the neotype of Staphylococcus aureus NCTC 8532 (ATCC 12600). ATCC 14990 has the characteristics which Winslow and Winslow attributed to the basionym, Albococcus epidermidis, and it conforms to the criteria proposed by the Subcommittee on Taxonomy of Staphylococcus and Micrococcus of the International Committee on Nomenclature of Bacteria, for the recognition of Staphylococcus epidermidis (1965). This paper constitutes the designation of ATCC 14990 as the neotype strain of Staphylococcus epidermidis under Rule 9d (1) Note 2(c) of the Bacteriological Code as approved at the 1967 Moscow Congress.

Twenty-three strains of bacteria isolated from mud samples taken in the Pacific Ocean at depths ranging from 9, 400 to 10, 400 meters have been found to be members of the genus Pseudomonas. From results of Adansonian analysis the strains appear to constitute a new species. Pseudomonas bathycetes n. sp. is therefore proposed and the median organism for the group, strain C2M2 (ATCC 23597), is designated as the type strain. Deoxyribonucleic acid base composition determinations and electron micrographs provide confirmatory evidence for the identification and classification of P. bathycetes.

A report of a working group of the Subcommittee on Taxonomy of the Actinomycetales of the International Committee on Nomenclature of Bacteria (ICNB). The group has been primarily concerned with recognition of type strains or other reference strains for the species of Actinomyces and with standardization of techniques for the study of the genus. Eleven species of Actinomyces or closely related organisms have been distributed and studied following techniques detailed in a “Manual of Procedures” which is included in the report.

SUMMARY. A comparative study of the biochemical reactions given by cultures of Enterobacter aerogenes and by members of the “Hafnia group” is reported. It is concluded that sufficient differences of taxonomic importance between the two warrant elevation of latter “group” from subspecies to species level. Further, it is shown that the correct name for the bacteria formerly called the “Hafnia group” or Enterobacter aerogenes subsp. alvei is Enterobacter hafniae (Moeller) Ewing.
