Seven strains of flagellated marine cocci have been subjected to taxonomic analysis. It is suggested that they be included in the genus Planococcus Migula, 1894. A revised description of the genus Planococcus is proposed. The strain Planococcus citreus CCM 316 (Micrococcus aquivivus ATCC 14404) is proposed as the neotype culture.

The results of a search for a neotype strain of Micrococcus freudenreichii Guillebeau 1891 indicate either that the strain CCM 764 should be designated neotype strain of M. freudenreichii and that this pecies be defined accordingly, or (2) that the name M. freudenreichii should be placed in the list of nomina rejicienda as a nomen dubium. It is recommended that the Subcommittee on Taxonomy of Staphylococci and Micrococci of the International Committee on Nomenclature of Bacteria be invited to evaluate the situation and subsequently initiate any action that may seem necessary in relation to the Judicial Commission.

The cultural, biochemical, and serological characteristics of an undescribed Pseudomonas species is presented. From the results obtained, it appears that the isolates studied constitute a new species. Pseudomonas. kingii n. sp. is therefore proposed, and the type organism for the group, isolate A977 (ATCC 25609) is designated as the type strain.

The range of cellular and colonial morphologies which occurred in a large group of A. israelii cultures, including recent isolates, from this country or abroad were studied. The strains were grown on BHI plates or in thiogly collate broth under conditions routinely used in a diagnostic laboratory. Stained smears or dark-field preparations from thioglycollate broth showed rods which varied from diphtheroid-like to long filaments. Microcolonies on BHI agar ranged from small and compact to spider-like with the latter predominating. Mature colonies on the same medium had a smooth or rough appearance. Rough colonies were found in two-thirds of the cultures. The smooth colonies were circular, convex and soft in consistency. The rough colonies were more irregular with a granular or a highly convoluted surface, friable to hard and adherent to the medium.

During the course of a large scale epidemiologic investigation, a Gram-negative nonlactose fermenting bacillus was isolated by rectal swab from a 2-year-old boy who was suffering from chronic diarrhea and headache. The child was from the Laka Tribe, residing in the village of Ouli Bangala, Prefecture of Logone Orientale, Subprefecture of Baiboukoum, Tchad, Africa. The biochemical characteristics and sugar fermentations were compatible with those of the genus Salmonella and serological evaluation revealed that the organism was a previously undescribed serotype: 6, 7: k: 1, 7. The new organism was named Salmonella sp. ser. baiboukoum after the region in Tchad where it was isolated.

The agent of bovine tuberculosis has been recognized at various times as a species or as a subspecies in the genus Mycobacterium Lehmann and Neumann. Although the organism is closely related to M. tuberculosis (Zopf) Lehmann and Neumann, the two species are clearly distinguished on the basis of differences in their rates of growth, pathogenicity for certain animals, and biochemical reactions. To date, however, none of the scientific names applied to the bovine tubercle bacillus has been validly published. It was recommended by the Judicial Commission of the International Committee on Nomenclature of Bacteria that the name Mycobacterium bovis (a name frequently used for this organism but not validly published) be reintroduced for this organism. Consequently, we propose Mycobacterium bovis as the name for the bovine tubercle bacillus and provide a description of the organism, together with a designation and description of the neotype strain (ATCC 19210; W. D. Yoder 18802–887).

The order Polyangiaceae is redefined to include only those myxobacters with cylindrical cells, It includes all organisms formerly included in the Sorangiaceae and the genera Chondromyces and Synangium. A new family, the Cystobacteraceae, type species Cystobacter fuscus (Polyangium fuscum), is erected for sporangial myxobacters with tapered vegetative cells. It includes the genera Stigmatella and Podangium in addition to Cystobacter.

A request is submitted to the Judicial Commission of the International Committee on Nomenclature of Bacteria to validate the proposal that the bacterial species Cristispira pectinis Gross 1910, 44 be recognized as type species of the genus Cristispira.

Seventeen strains of Clostridium limosum (Prévot) isolated from soil and fatal infections in cattle, swine, chickens, alligators, and from other sources are described. Strains of this species are proteolytic, nonsacc harolytic, slightly toxic, and pathogenic for laboratory animals, and produce acetic acid from peptone media as the only major acid. Large quantities of amines are also produced. Four strains representing variant types of the species could be differentiated from the others by serologic reactions, differences in cell wall composition and amine products.

Budding as a mode of replication of nitrite oxidizing bacteria was observed and illustrated by Winogradsky in his work on Nitrobacter, and, shortly thereafter, by Stutzer and Hartleb, studying Nitromicrobium germinans. The identity of this bacterium with the Nitrobacter cultures of Winogradsky was established by Stutzer. Nitrorcrobium is thus a later synonym to Nitrobacter. The species name germinans would have had priority over winogradsky but it was overlooked. Opinions 20 and 23 of the Judicial Commission clearly validate Nitrobacter winogradskyi Winslow et at. 1917, and thus Nitromicrobium germinans is to be placed among the synonyms of N. winogradskyi.

It is proposed to change the Danish nomenclature for 82 types of pneumococci by adding an F to the first established types in 16 groups. This altered nomenclature is recommended as the international system.

The name Lactobacillus acidophilus has never been validly published. Because it has been widely used for many years, the name is here proposed as a new combination (Lactobacillus acidophilus (Moro) comb. nov.). A description of the species is furnished. ATCC 4356 is designated as the neotype strain.
