Taxonomy of Some Swine Mycoplasmas: Mycoplasma suipneumoniae Goodwin et al. 1965, a Later, Objective Synonym of Mycoplasma hyopneumoniae Mare and Switzer 1965, and the Status of Mycoplasma flocculare Meyling and Friis 1972
More LessTwo mycoplasmas, Mycoplasma hyopneumoniae Mare and Switzer 1965 and M. suipneumoniae Goodwin et al. 1965, have been named and described as etiological agents in enzootic pneumonia of pigs. Authentic cultures of strain 11, the type strain of M. hyopneumoniae, are no longer extant. Strain J, the type strain of M. suipneumoniae, is here proposed as the neotype strain of M. hyopneumoniae. Since the names M. hyopneumoniae and M. suipneumoniae are now based on the same type, they are objective synonyms. The name M. hyopneumoniae, being the earlier of the two, has priority and is therefore the correct name of the species. The name M. suipneumoniae is thus illegitimate as a later, objective synonym. Another swine isolate, M. flocculare, although sharing a number of biological features with strains of M. hyopneumoniae, is nevertheless serologically distinct not only from the latter but also from all of the other currently recognized species of Mycoplasma. It is thus confirmed here as a unique species. Biological and serological characterizations of the type and proposed neotype strains are given.

Serratia fonticola, a New Species from Water
More LessTwenty strains of Enterobacteriaceae isolated from water are assigned to a new species in the genus Serratia on the basis of phenetic (numerical analysis) and genetic (deoxyribonucleic acid [DNA]-DNA hybridization) evidence. They are closely related to each other (75 to 91% DNA-DNA relatedness) and show 50% DNA relatedness with species of Serratia but only 20 to 30% relatedness with other members of the family Enterobacteriaceae. The strains are acetoin, gelatinase, and deoxyribonuclease negative, but lysine, ornithine decarboxylase, and Tween-esterase positive. They are metabolically very active, fermenting all the sugars and alcohols tested except melezitose, inulin and sorbose. The name Serratia fonticola is proposed for these strains. Strain 11 (= ATCC 29844) is the type strain of the species.

Treponema innocens, a New Species of Intestinal Bacteria, and Emended Description of the Type Strain of Treponema hyodysenteriae Harris et al.
More LessTwelve treponemes with serpentine morphology were isolated from pigs and dogs and were compared with strain B78, the type strain of Treponema hyodysenteriae Harris et al. Nine of the 12 were isolated from cases of swine dysentery, and these were similar in characteristics to strain B78. The three other isolates were not enteropathogenic for swine and could be differentiated from the aforementioned nine isolates on the basis of enteropathogenicity, hemolytic pattern, deoxyribonucleic acid homology, fructose fermentation, and indole production. The morphological and metabolic characters of the 12 isolates and an emended description of strain B78, the type strain of T. hyodysenteriae, are presented in this report. Based on these data, the nonpathogenic types are regarded as belonging to a new species, Treponema innocens. The type strain of T. innocens is strain B256 (=ATCC 29796).

Comprehensive Numerical Classification of 369 Strains of Mycobacterium, Rhodococcus, and Nocardia
More LessA numerical analysis of 369 strains received as members of the genus Mycobacterium, Rhodococcus (formerly Gordona), Nocardia, or Corynebacterium was carried out using 88 characters. Of the strains tested, 345 mycobacteria, rhodococci, and nocardiae formed four distinct clusters at a similarity level of 85%. The first cluster was composed of slowly growing mycobacteria; the second cluster, of strains of Mycobacterium flavescens and M. thermoresistibile; the third cluster, of strains of rapidly growing mycobacteria; and the fourth cluster, of strains of Rhodococcus and Nocardia. Strains of three species of rapidly growing mycobacteria, M. agri, M. smegmatis, and M. vaccae, were located outside of these clusters. The fourth cluster could be divided into three subclusters, one consisting of rhodococci plus some strains of Nocardia asteroides, a second consisting of the remaining strains of Nocardia, and a third consisting of strains of Rhodococcus aurantiacus (Gordona aurantiaca) and Jensenia canicruria.

Transfer of Five Species and Two Subspecies of Spirillum to Other Genera (Aquaspirillum and Oceanospirillum), with Emended Descriptions of the Species and Subspecies
More LessIn 1973, five new species and two new subspecies of the genus Spirillum Ehrenberg 1832 were described by Terasaki (Bull. Suzugamine Women's Coll. Nat. Sci. 17:1-71, 1973). In the same year, Hylemon et al. (P. B. Hylemon, J. S. Wells, Jr., N. R. Krieg, and H. W. Jannasch, Int. J. Syst. Bacteriol. 23:340-380, 1973) proposed that the genus Spirillum be divided into three genera: Spirillum, Aquaspirillum, and Oceanospirillum. Accordingly, on the basis of the original and subsequently determined characters of the various new species and subspecies, the following transfers from the genus Spirillum are proposed. S. psychrophilum Terasaki, S. itersonii subsp. nipponicum Terasaki, and S. peregrinum subsp. integrum Terasaki are transferred to the genus Aquaspirillum as A. psychrophilum (Terasaki) comb. nov., A. itersonii subsp. nipponicum (Terasaki) comb. nov., and A. peregrinum subsp. integrum (Terasaki) comb. nov., respectively. The type strains for these taxa are IFO 13611, IFO 13615, and IFO 13617, respectively. The marine species S. hiroshimense Terasaki, S. pelagicum Terasaki, S. pusillum Terasaki, and S. multiglobuliferum Terasaki are transferred to the genus Oceanospirillum as O. hiroshimense (Terasaki) comb. nov., O. pelagicum (Terasaki) comb. nov., O. pusillum (Terasaki) comb. nov., and O. multiglobuliferum (Terasaki) comb. nov., respectively. The type strains for these species are IFO 13616, IFO 13612, IFO 13613, and IFO 13614, respectively. Emended descriptions of these species and subspecies are given.

Cryptococcus vishniacii sp. nov., an Antarctic Yeast
More LessAntarctic soil samples collected by W. V. Vishniac contained (among other microbes) 98 isolates of undescribed, imperfect yeasts. These isolates clustered as 16 biotypes of greater than 90% similarity to each other but less than 90% similarity to all previously described yeast species. We propose to include all such isolates in the new species Cryptococcus vishniacii, named in honor of W. V. Vishniac. C. vishniacii grows at 4°C and below but not at 26°C and above, is cream-colored in mass, lacks pseudomycelia, is nonfermentative, produces "amylose," assimilate (at least) glucose, maltose, melezitose, trehalose, and xylose, and uses nitrate-N. The type strain, MTSW 304Y268 (= ATCC 36649), does not grow at 21 to 22°C or above and assimilates (additionally) l-arabinose, d-glucuronic acid, raffinose, l-rhamnose (weakly), sucrose, succinate, and citrate.

Pichia opuntiae, a New Heterothallic Species of Yeast Found in Decaying Cladodes of Opuntia inermis and in Necrotic Tissue of Cereoid Cacti
More LessA new heterothallic species of Pichia has been recovered 25 times from widely separated cactus substrates. The organism has been named Pichia opuntiae because the sexually most compatible strains were isolated from Opuntia inermis in Australia. Two varieties are designated based on differences in physiology, habitat, and geographic distribution. P. opuntiae var. opuntiae has a maximum temperature for growth of 30 to 33°C and assimilates citric acid strongly, but assimilation of cellobiose is latent, weak, or negative. P. opuntiae var. thermotolerans grows well at 37°C, but not at 39°C; it assimilates cellobiose strongly but does not assimilate citric acid. Ecologically, P. opuntiae var. opuntiae is associated with Opuntia inermis (tribe Opuntiaeae, subtribe Opuntiinae) in Australia; P. opuntiae var. thermotolerans is associated with species of the cactus tribe Pachycereeae, subtribe Pachycereinae, from various locations in the North American Sonoran Desert. A discussion of the physiological and host-plant shifts for these two varieties and three similar cactophilic yeasts is presented. The base composition of the nuclear deoxyribonucleic acid of P. opuntiae var. opuntiae (average of four strains) is 33.64 ± 0.25 mol% guanine plus cytosine and that of P. opuntiae var. thermotolerans (average of 3 strains) is 33.13 ±0.23 mol% guanine plus cytosine. The type strain of P. opuntiae and of the type variety, P. opuntiae var. opuntiae, is UCD-FS&T 77-40 (= ATCC 36836 = CBS 7010). The type strain of P. opuntiae var. thermotolerans is UCD-FS&T 76-211 (= ATCC 36834 = CBS 7012).

Proposal of Minimal Standards for Descriptions of New Species of the Class Mollicutes: International Committee on Systematic Bacteriology Subcommittee on the Taxonomy of Mollicutes †
A proposal for minimal standards for descriptions of new species of the class Mollicutes is presented here with the approval of the International Committee on Systematic Bacteriology (ICSB) and its Judicial Commission. The proposal is a revised and extended version of a similar proposal of minimal standards for descriptions of species of the order Mycoplasmatales previously published by the Subcommittee. The major characteristics of the class Mollicutes are summarized. The classification of an organism as a member of the class is based primarily on the following criteria: Lack of a cell wall, typical colonial appearance, filterability through a membrane filter with a pore size 450 nm in diameter, and absence of reversion to a bacterium under conditions ordinarily favorable for reversion. Placement of these organisms into families is based on genome size, sterol requirements, and morphology; their assignment to genera is based on morphological, cultural, and biochemical properties. Demonstration that an organism differs from existing species requires determination of serological, cultural, and biochemical characteristics. Other tests may be useful or, under certain conditions, necessary.
