Summary: Two similar micro-organisms with the characteristics of the order Mycoplas-matales were isolated from the eyes of calves with conjunctivitis. Both isolates produced only a slight pH decrease in broth and did not ferment glucose or hydrolyse arginine or urea -- hence they were almost undetectable by fluid cultures. Other biological characters included sterol dependence, indicative of the genus Mycoplasma, production of film and spots, growth at low temperature (20°C) or low pH (4.7), and failure to reduce tetrazolium. The two strains were serologically indistinguishable from each other, but distinct from known bovine and other Mycoplasma species tested. Because of their distinct biological and serological characteristics they are proposed as forming a separate new species, Mycoplasma verecundum, with strain 107 (nctc10145) as the type strain.

The microbial population in the rhizosphere of wheat, oats, alfalfa, and peas was studied and the relative abundance of different types of micro-organisms recorded. By means of the plating method it was found that bacteria and actinomycetes were 7 to 71 times greater in the rhizosphere than in the soil distant from the roots, whereas fungi were but 0.75 to 3.1 times more numerous.Different varieties of plants affected the activity of the various groups of soil micro-organisms differently. Thus fungi were more numerous in the rhizosphere of oats, and bacteria in the rhizosphere of alfalfa. Seventeen genera of fungi were represented in isolates from the rhizosphere of seedlings and the soil distant from the roots. However, no marked difference was observed in the types isolated from the rhizosphere of different varieties of seedlings. A fungus isolated from the rhizosphere of alfalfa proved to be a new species and the genus Spicularia Persoon was amended to include it.

A New Species

The gut of honey bees is characterized by a stable and relatively simple community of bacteria, consisting of seven to ten phylotypes. Two closely related honey bees, Apis mellifera (western honey bee) and Apis cerana (eastern honey bee), show a largely comparable occurrence of those phylotypes, but a distinct set of bacterial species and strains within each bee species. Here, we describe the isolation and characterization of Ac13T, a new species within the rare proteobacterial genus Frischella from A. cerana japonica Fabricius. Description of Ac13T as a new species is supported by low identity of the 16S rRNA gene sequence (97.2 %), of the average nucleotide identity based on orthologous genes (77.5 %) and digital DNA–DNA hybridization relatedness (24.7 %) to the next but far related type strain Frischella perrara PEB0191T, isolated from A. mellifera. Cells of Ac13T are mesophilic and have a mean length of 2–4 µm and a width of 0.5 µm. Optimal growth was achieved in anoxic conditions, whereas growth was not observed in oxic conditions and strongly reduced in microaerophilic environment. Strain Ac13T shares several features with other members of the Orbaceae , such as the major fatty acid profile, the respiratory quinone type and relatively low DNA G+C content, in accordance with its evolutionary relationship. Unlike F. perrara , strain Ac13T is susceptible to a broad range of antibiotics, which could be indicative for an antibiotic-free A. cerana bee keeping. In conclusion, we propose strain Ac13T as a novel species for which we propose the name Frischella japonica sp. nov. with the type strain Ac13T (=NCIMB 15259=JCM 34075).

A New Species

A new rod-shaped endospore-forming bacterium is described, which was isolated from the hindgut of the termite Reticulitermes santonensis (Feytaud). The isolate stains Gram negative and its DNA has a guanine-plus-cytosine content of 35 mol%. Despite the Gram-staining reaction, both biochemical and physiological features place the isolate in the genus Bacillus and indicate a phenotypic resemblance to the Bacillus firmus–lentus group of species. On the basis of comparative 16S rRNA analysis and some phenotypic features the isolate clearly represents a new species for which the name Bacillus oleronius is proposed. The type strain is Bacillus oleronius Rt 10 (DSM 9356).Key words: Bacillus, termites, hindgut flora.

Leptoxyphium is a relatively poorly known genus of sooty moulds in Capnodiaceae (Dothideomycetes). This paper introduces one new species of Leptoxyphium, L. glochidion and the first record of L. kurandae for China. L. glochidion is introduced as a new species based on morphology and molecular data and is compared with related taxa. Descriptions, illustrations and notes are provided for the two species, which are analyzed by ITS, LSU and SSU sequence data. The phylogenetic analysis shows that the two species cluster in Leptoxyphium (Capnodiaceae). L. glochidion separates from other species of the genus, while L. kurandae clustered with the type strain

Mycoplasma salivarium was isolated from the oropharynx of four out of seven Galagos and M. arthritidis was obtained from the nasopharynx of three out of six Galagos. Biochemical and serological studies failed to differentiate the M. salivarium isolates from those of human origin. The M. arthritidis isolates appeared identical with strains occurring in rats and they were found to be highly arthritogenic when injected i.v. into young rats.Five out of seven animals harbored an unidentified glucose-fermenting Mycoplasma species which appeared to be biochemically and serologically related to, but distinct from, M. felis of cat origin. This preliminary investigation indicated that the glucose-fermenting Galago strains represented a new species of the Mycoplasmataceae.

Abstract A catalase and oxidase-positive strain BA0156T was isolated from a cyanobacterial mat collected from the farmland mud cultivated with sugarcane from Ahmednagar, India. The 16S rRNA gene of strain BA0156T showed the highest percent sequence similarity with Hydrogenophaga borbori LMG 30805T (98.55 %), followed by H. flava DSM 619T (98.35 %) and H. intermedia DSM 5680T (98.21 %). The strain BA0156T consisted of major fatty acids, C16:0 (25.1 %) and C17:0 cyclo (3.9 %), whereas phosphatidylethanolamine and diphosphatidylglycerol were the major polar lipids. The OrthoANI and dDDH values between strain BA0156T and its closest relative H. borbori LMG 30805T were 84.59 % and 28.3 %, respectively. The DNA G+C content of strain BA0156T was 69.42 mol %. Furthermore, the biochemical and physiological features of strain BA0156T showed a distinct pattern from their closest phylogenetic neighbours. The phenotypic, genotypic and chemotaxonomic characteristics indicated that the strain BA0156T represents a new species for which the name Hydrogenophaga crocea (type strain BA0156 T = MCC 3062T = KCTC 72452T = JCM 34507T) is proposed.

We describe a new species of Cephalodella, C. acidophila n. sp., from the plankton of two extremely acidic mining lakes (pH Cephalodella delicata Wulfert. It shares with the latter an almost identical trophi morphology and anatomical organization, but differs clearly by form and length of its toes, larger body size, and ecology. Laboratory experiments revealed that the species is acidophilic, i.e. it thrives at low pH (Chlamydomonas acidophila. The easily cultured species has previously been used in various experimental studies, but has only now been recognized as an undescribed species.
