The Distal Gut Bacterial Community of Some Primates and Carnivora.

Huge numbers of bacteria reside in the digestive tract of host and these microorganisms play a vital role in the host health, especially in the digestion of food and the development of immune system. Host phylogeny and diet, especially long-term diet, both have great influence on the gut bacterial community. Other aspects of host, such as gender, age, and the geography and weather they lived, are also correlated to their gut bacterial community. Feces are usually used for gut bacteria study and fecal bacteria can represent the distal gut bacteria. In order to determine the influence of the host phylogeny and diet on the composition of distal gut bacterial community and to interpret bacterial population and diversity in the intestinal of animals, the distal gut bacterial community of four kinds of primates and five kinds of carnivora (including herbivorous, omnivorous, and carnivorous) were investigated using high-throughput sequencing and the isolation of the Actinobacteria from fresh feces of several primates was processed. The results showed the host phylogeny had a greater influence on the distal gut bacterial community of the primates and carnivora than the host diet. A total of 44 bacteria phyla and two archaea phyla were detected, which indicated that the distal gut bacteria of these animals were abundant. The distal gut bacteria were relatively stable and wildly shared in primates and carnivora. The difference in distal gut bacteria of the two animal orders is mainly determined by relative abundance of most distal gut bacteria rather than by the taxa of these bacteria.

(type strain YIM 121936T=KCTC 39738T=DSM 102155T) and Kineococcus aureolus sp. nov. (type strain YIM 121940T=KCTC 39739T=DSM 102158T) are proposed, respectively.

Mobilicoccus caccae sp. nov., isolated from the faeces of the primate Rhinopithecus roxellanae.

A novel actinobacterium, designated YIM 101593T, was isolated from the faeces of a primate (Rhinopithecus roxellanae) living in Yunnan Wild Animal Park in Yunnan province, south-west China. The isolate was Gram-stain-positive, facultatively anaerobic, coccus-shaped, oxidase-negative and motile. The cell wall contained meso-diaminopimelic acid as its diagnostic diamino acid, and mannose, ribose, glucose, galactose and arabinose were detected as the main whole-cell sugars. The predominant menaquinone was MK-8(H2). The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, two glycolipids, three unidentified phospholipids and two unidentified lipids. The major fatty acids were C17 : 1ω8c, C15 : 0 and summed feature 4 (anteiso-C17 : 1 B and/or iso-C17 : 1 I). The DNA G+C content was 69.8 mol%. The 16S rRNA gene sequence similarity between strain YIM 101593T and Mobilicoccus pelagius was 97.9 %, and the two strains formed a distinct lineage stably on the basis of phylogenetic analysis. In addition, DNA-DNA relatedness between the two strains was 49.0±5.1 %. On the basis of chemotaxonomical and physiological characteristics and the phylogenetic analysis, strain YIM 101593T should be considered to represent a novel species of the genus Mobilicoccus, for which we propose the name Mobilicoccus caccae sp. nov., with the type strain YIM 101593T (=DSM 27611T=CCTCC AB 2013229T).

Enterovirga rhinocerotis gen. nov., sp. nov., isolated from Rhinoceros unicornis faeces.

A novel strain, YIM 100770T, was isolated from Rhinoceros unicornis faeces collected from Yunnan Wild Animal Park, China. The taxonomic status was determined based on the physiological, biochemical and phylogenetic characteristics. Strain YIM 100770T was observed to be rod-shaped, non-motile, Gram-stain negative and aerobic. The G+C content of the genomic DNA was determined to be 68.5 mol%. The cells of strain YIM 100770T contain ubiquinone Q-10 as the respiratory quinone. The major fatty acids (>1%) were identified as Summed feature 8 (C18:1 ω7c and/or C18:1 ω6c; 78.1%), Summed feature 4 (iso-C17:1-I and/or anteiso-C17:1-B; 12.9%), C19:0 cyclo ω8c (2.8%), C16:0 (2.2%) and C18:0 (2.2%). Comparison of 16S rRNA gene sequences revealed the strain show high similarities with the members of the genera Psychroglaciecola (94.5%), Methylobacterium (90.5-94.1%) and Microvirga (92.0-93.3%) in the family Methylobacteriaceae. In addition, the strain also showed high similarities with the members of the genera Chelatococcus (93.7-94.0%) and Pseudochelatococcus (93.1-93.7%) in the family Beijerinckiacea, and the genus Bosea (93.1-93.8%) in the family Bradyrhizobiaceae. The phylogenetic analysis, combined with the chemical characteristics, suggest that the strain represents a novel genus in the order Rhizobiales of the class Alphaproteobacteria, for which the name Enterovirga rhinocerotis gen. nov., sp. nov. is proposed. The type strain of E. rhinocerotis is YIM 100770T (=DSM 25903T = CCTCC AB 2012048T).

Corynebacterium faecale sp. nov., isolated from the faeces of Assamese macaque.

A Gram-stain-positive, facultatively anaerobic, short rod-shaped, oxidase-negative and non-motile novel strain, designated YIM 101505T, was isolated from the faeces of a primate, Assamese macaque, and was studied to determine its taxonomic position. The cell wall contained meso-diaminopimelic acid and short-chain mycolic acids. Whole cell sugars were mannose, galactose and arabinose as major components. The major fatty acids (>10 %) were C18 : 1ω9c, C16 : 0 and C17 : 1ω8c and the major menaquinone was MK-9(H2). The polar lipids included diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside, glycolipid and six unidentified lipids. The new isolate shared most of the typical chemotaxonomic characteristics of members of the genus Corynebacterium. The closest related species was Corynebacterium efficiens based on 16S rRNA gene (98.1 % similarity) and partial rpoB gene (91.4 % similarity) sequences. Similarities with other species of this genus were below 97 % based on the 16S rRNA gene. The DNA-DNA hybridization value between YIM 101505T and C. efficiens DSM 44549T was 47.7±3.6 %. Moreover, the physiological and biochemical characteristics of YIM 101505T and C. efficiens DSM 44549T were different. Thus, strain YIM 101505T is considered to represent a novel member of the genus Corynebacterium, for which the name Corynebacterium faecale sp. nov. is proposed. The type strain is YIM 101505T (=DSM 45971T=CCTCC AB 2013226T).

Tessaracoccus rhinocerotis sp. nov., isolated from the faeces of Rhinoceros unicornis.

A novel Gram-stain-positive, non-spore-forming, irregular rod-shaped, non-motile and facultatively anaerobic actinobacterium, designated strain YIM 101269T, was isolated from the faeces of Rhinoceros unicornis living in Yunnan Wild Animal Park, Yunnan province, south-west China. The isolate grew at 10-35 °C, at pH 6-12 and with 0-9 % (w/v) NaCl. The cell-wall peptidoglycan of the organism contained ll-diaminopimelic acid as the diagnostic diamino acid. The polar lipids detected were diphosphatidylglycerol, phosphatidylglycerol, three unidentified polar lipids, one unidentified aminophospholipid and three unknown glycolipids. The major cellar fatty acid was anteiso-C15 : 0.MK-10(H4) was the predominant menaquinone. The DNA G+C content was 69.5 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain YIM 101269T belonged to the genus Tessaracoccus, closely related to Tessaracoccus flavescens DSM 18582T (97.4 % similarity). Based on the evidence from the present study, strain YIM 101269T is considered to represent a novel species of the genus Tessaracoccus, for which the name Tessaracoccus rhinocerotis sp. nov. is proposed. The type strain is YIM 101269T ( = DSM 27579T = CCTCC AB 2013217T).

Microbacterium faecale sp. nov., isolated from the faeces of Columba livia.

A novel, yellow, aerobic strain, YIM 101168T, isolated from the faeces of a dove (Columba livia), was studied to determine its taxonomic position. Cells were Gram-stain-positive, short rod-shaped, oxidase-negative, catalase-positive and non-motile. The strain could grow at 7-37 °C, at pH 6-10 and in the presence of 0-13 % (w/v) NaCl. The strain had a 16S rRNA gene sequence similarity and DNA-DNA hybridization relatedness value with Microbacteriumgubbeenense NCIMB 30129T of 97.8 % and 41.5±8.7 %, respectively. Ornithine was detected as the diagnostic amino acid in the hydrolysate of the cell wall. Whole-cell sugars were found to be galactose, glucose, rhamnose, mannose and ribose. Major fatty acids (>10 %) were iso-C16 : 0, anteiso-C15 : 0 and anteiso-C17 : 0. Major menaquinones were identified as MK-10, MK-11 and MK-12. The polar lipids included diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, glycolipids and four unidentified lipids. The phylogenetic analyses as well as the chemotaxonomic and phenotypic characteristics indicate that strain YIM 101168T represents a novel species of the genus Microbacterium; the name Microbacterium faecale sp. nov. is proposed for the novel species and the type strain is YIM 101168T (=DSM 27232T=KCTC 39554T=CGMCC 1.15152T).
