Mycoplasma collis, a New Species Isolated from Rats and Mice
More LessMycoplasmas isolated from the conjunctivas and nasopharynges of rats and mice were shown to be serologically distinct from 78 previously recognized Mycoplasma and Acholeplasma species. Three cloned strains obtained from separate animal colonies were examined in detail. These strains were indistinguishable from each other. Strain 58B (= NCTC 10197) is designated the type strain of a new species, Mycoplasma collis.

Treponema pectinovorum sp. nov. Isolated from Humans with Periodontitis
More LessA new species of Treponema, Treponema pectinovorum, which was isolated from supragingival and subgingival samples from patients with periodontitis, is described. This new anaerobic species requires rumen fluid or short-chain volatile fatty acids and a fermentable energy source. Pectin, polygalacturonic acid, glucuronic acid, and galacturonic acid are the only substrates fermented. The main end products of fermentation are acetic and formic acids; traces of pyruvic and lactic acids occasionally are found. The type strain of T. pectinovorum is strain VPI D-36DR-2 (= ATCC 33768). The guanine-plus-cytosine content of the deoxyribonucleic acid of the type strain is 39 mol%.

Taxonomy of Marine Pseudomonas Species: P. stanieri sp. nov.; P. perfectomarina sp. nov., nom. rev.; P. nautica: and P. doudoroffii
More LessRecent studies of the evolutionary relationships of nonfermentative, gram-negative, rod-shaped, polarly flagellated, marine bacteria have indicated that some are members of the lineage which includes the type species of the genus Pseudomonas, Pseudomonas aeruginosa. As a result of these findings, one species equivalent (group G-l) with a guanine plus cytosine content slightly beyond the lower limit proposed for Pseudomonas is now included in this genus under the designation Pseudomonas stanieri sp. nov. (type strain 146 = ATCC 27130). In addition, “Pseudomonas perfectomarinus,” an organism not included in the Approved List of Bacterial Names, is a recognizable species and part of this lineage. This name has, therefore, been revived and corrected to Pseudomonas perfectomarina sp. nov., nom. rev. (type strain 218 = ATCC 14405). The phenotypes of these two species and their type strains are described along with those for two other marine Pseudomonas, Pseudomonas nautica and Pseudomonas doudoroffii.

Notes: Listeria welshimeri sp. nov. and Listeria seeligeri sp. nov.
More LessThe names Listeria welshimeri sp. nov. and Listeria seeligeri sp. nov. are proposed for two groups of gram-positive, asporogenous, motile, aerobic bacilli that were previously classified as nonpathogenic Listeria monocytogenes. The separation of both of these new species from L. monocytogenes is supported by the results of deoxyribonucleic acid relatedness studies, determinations of biochemical characteristics, and studies of pathogenicity for adult mice. The new species differ from each other and from the recently proposed species Listeria innocua by deoxyribonucleic acid relatedness and biochemical features. The type strain of L. welshimeri is strain CIP 8149, and the type strain of L. seeligeri is strain CIP 100100.

Corynebacterium minutissimum sp. nov., nom. rev.
More Less“Corynebacterium minutissimum” Sarkany, Taplin, and Black 1962 was not included on the Approved Lists of Bacterial Names and consequently has no standing in bacteriological nomenclature. However, the results of numerical taxonomic, cell wall, lipid, and deoxyribonucleic acid base composition studies indicate that the organism designated the type strain by Sarkany et al. (strain NCTC 10288) and other strains studied by these workers form a distinct taxon within the genus Corynebacterium. The name Corynebacterium minutissimum is here revived for the same organism to which the name was applied by Sarkany et al. The type strain is strain NCTC 10288.

Subspecific Taxonomy of Francisella tularensis McCoy and Chapin 1912 †
More LessIn this note we examine the nomenclature and extend the descriptions of the subspecies of Francisella tularensis McCoy and Chapin that were proposed by Olsufjev and Meshcheryakova (J. Hyg. Epidemiol. Microbiol. Immunol. 26:291-299, 1982) but have not been validated by publication or listing in the International Journal of Systematic Bacteriology. Biochemical, pathological, ecological, and geographical characteristics are used to define three subspecies within F. tularensis; these are F. tularensis subsp. tularensis (McCoy and Chapin) subsp. nov. (type strain, GIEM Schu), F. tularensis subsp. holarctica Olsufjev and Meshcheryakova 1982, 296 (type strain, GIEM 503), and F. tularensis subsp. mediasiatica (Aikimbaev 1966) Olsufjev and Meshcheryakova 1982, 296 (type strain, GIEM 543). F. tularensis subsp. holarctica includes three biovars, I Erys (erythromycin susceptible), II Eryr (erythromycin resistant), and japonica. The now avirulent type strain of F. tularensis McCoy and Chapin (strain B-38 [= ATCC 6223]) is not totally characteristic of F. tularensis subsp. tularensis, and that is why another type strain is proposed for this subspecies.

Emendation of Methylobacterium Patt, Cole, and Hanson 1976; Methylobacterium rhodinum (Heumann 1962) comb. nov. corrig.; Methylobacterium radiotolerans (Ito and Iizuka 1971) comb. nov. corrig.; and Methylobacterium mesophilicum (Austin and Goodfellow 1979) comb. nov.
More LessThe present definition of the genus Methylobacterium excludes organisms which do not utilize methane facultatively. However, reports have indicated that cultures of the type strain of the type species, Methylobacterium organophilum, can lose this feature easily. Furthermore, studies have shown that M. organophilum is phenotypically highly similar to the methane-nonutilizing, pink-pigmented, facultatively methylotrophic bacteria and that the latter should be excluded from the various genera to which they have been assigned previously. Therefore, in accordance with an earlier suggestion, we propose that the description of the genus Methylobacterium be emended to permit the inclusion of methane-nonutilizing organisms which are otherwise highly similar to the type species. We further propose that all of the pink-pigmented, facultatively methylotrophic bacteria, which include the species Pseudomonas rhodos, Pseudomonas radiora, and Pseudomonas mesophilica, be transferred to the genus Methylobacterium.

Amended Description of the Genus Xenorhabdus Thomas and Poinar
More LessBacteria symbiotically associated with entomogenous nematodes were described and placed in the genus Xenorhabdus in 1979. Since that time, additional studies on members of the genus, the designation of the new subspecies Xenorhabdus nematophilus subsp. nematophilus and X. nematophilus subsp. bovienii, the description of a new strain of X. nematophilus subsp. poinarii, and the observation of colonial dimorphism in members of the genus have brought about the necessity for an amended description. The description of the genus Xenorhabdus is amended to include dimorphism and additional characteristics.

Separation of Kluyvera and Buttiauxella by Biochemical and Nucleic Acid Methods
More LessWe propose to maintain the genera Buttiauxella and Kluyvera, which are phenotypically similar, as separate genera in the Enterobacteriaceae. This separation is supported by the following findings: (i) strains of Kluyvera ascorbata and Kluyvera cryocrescens were related to Buttiauxella agrestis ATCC 33320T (T = type strain) at levels of 32 to 36% and 30 to 31%, respectively, as determined by deoxyribonucleic acid relatedness (nitrocellulose filter method at 52.8°C); (ii) the guanine-plus-cytosine ratios of Buttiauxella and Kluyvera deoxyribonucleic acids 48 to 50 mol% and 55 to 57 mol%, respectively; and (iii) production of indole and lysine decarboxylase and fermentation of sucrose in 2 days could differentiate Kluyvera from Buttiauxella.

Streptococcus sobrinus nom. rev. and Streptococcus ferus nom. rev.: Habitat of These and Other Mutans Streptococci
More LessStreptococcus sobrinus and Streptococcus ferus were not included on the Approved List of Bacterial Names in 1980. Type strains of these species are now available, and I propose that they be recognized. The available evidence indicates that S. ferus is a commensal of wild rats and that S. sobrinus and the other mutans streptococci (except S. ferus) are human commensals.

Cytochrome Oxidase Analyses of Bacillus Strains: Existence of Oxidase-Positive Species
More LessAnalyses of 173 Bacillus strains (representing 30 species) with a newly developed quantitative colorimetric N,N,N',N'-tetramethyl-p-phenylenediamine oxidase assay revealed the presence of many oxidase-positive species. Of 144 mesophilic strains analyzed, the following were oxidase positive: 16 of 16 Bacillus alvei strains, 7 of 9 Bacillus laterosporus strains, 5 of 10 Bacillus circulans strains, 4 of 5 Bacillus macerans strains, 2 of 5 Bacillus firmus strains, 1 strain of Bacillus sphaericus, and 1 strain of Bacillus brevis. The thermophilic organisms Bacillus stearothermophilus T-10 and ATCC 8005, “Bacillus caldotenax” (one strain), and “Bacillus thermodenitrificans” DSM 465 were also oxidase positive. In fact, when the oxidase-positive thermophilic strains were grown at 65°C, they exhibited very high oxidation rates; most of these rates were equivalent to the high rates of reaction recorded for strains of Pseudomonas aeruginosa and Neisseria spp. Most mesophilic Bacillus strains and all of the psychrophiles examined were oxidase negative or oxidase indeterminate (the latter had oxidase rates equilavent to the rates in the N,N,N',N'-tetramethyl-p-phenylenediamine autooxidation reaction). Spectral absorbance analyses on membranes of oxidase-positive B. alvei strain 385 revealed the presence of a type c cytochrome with cytochrome oxidases o and a+a 3, Bacillus pumilus strains which could not oxidize N,N,N',N'-tetramethyl-p-phenylenediamine lacked type c cytochromes but possessed these two oxidases. The paper strip Kovacs oxidase test with Marion reagent could be routinely used for detecting oxidase-positive Bacillus strains. A distinct class of oxidase-positive strains should be identified, which might eventually be useful for identification studies.

Speciation, Species Delineation, and Electrophoretic Isoenzyme Patterns of the Type Strains of Kluyveromyces van der Walt emend. van der Walt
More LessThe type strains of the 20 species of the yeast genus Kluyveromyces sensu van der Walt 1970 were studied by gel electrophoresis of 11 isofunctional enzymes. These enzymes included five oxidoreductases (alcohol dehydrogenase [EC 1.1.1.1], lactate dehydrogenase [EC 1.1.1.27], malate dehydrogenase [EC 1.1.1.37], catalase [EC 1.11.1.6], and superoxide dismutase [EC 1.15.1.1]), five hydrolases (esterase [EC 3.1.1.1], alkaline phosphatase [EC 3.1.3.1], α-glucosidase [EC 3.2.1.20], β-glucosidase [EC 3.2.1.21], and exo-β-glucanase [EC 3.2.1.58]), and one lyase (aldolase [EC 4.1.2.12]). Polymorphism was evident in most of the enzymes studied. Each type strain had a unique pattern when all enzymes were considered. The results of a multivariate analysis of the electrophoretic patterns supported the division of the genus into 13 species, 2 of which comprised four and five taxa, respectively, which were recognized in 1970. Enzyme electrophoresis provided evidence that widespread gene flow does not necessarily occur between yeasts which are able to hybridize in the laboratory.

Opposition to the Proposal to Replace the Family Name Enterobacteriaceae †
More LessThe Subcommittee on the Taxonomy of Enterobacteriaceae unanimously recommends that the proposal to replace the family name Enterobacteriaceae with Escherichiaceae be rejected by the Judicial Commission. The arguments in support of this recommendation are as follows: (i) Enterobacteriaceae is a legitimate name that has been specifically conserved as an exception to Rule 9 of the International Code of Nomenclature of Bacteria; (ii) the continued use of this name satisfies Principle 1 of the Bacteriological Code (to “aim at stability of names; avoid or reject the use of names which may cause error or confusion; and avoid the useless creation of names”); and (iii) Enterobacteriaceae is also specifically in accord with General Consideration 6, Principles 1, 8, and 9, Rules 21b, 23a, and 56b, and Opinion 15 of the Bacteriological Code, whereas the proposal to use Escherichiaceae violates each of these portions of the Bacteriological Code.
