  • Uneven Distribution of Cobamide Biosynthesis and Dependence in Bacteria Predicted by Comparative Genomics
    The ISME Journal (2018) 13:789–804 https://doi.org/10.1038/s41396-018-0304-9 ARTICLE Uneven distribution of cobamide biosynthesis and dependence in bacteria predicted by comparative genomics 1 1 1 1,2 3,4 3 Amanda N. Shelton ● Erica C. Seth ● Kenny C. Mok ● Andrew W. Han ● Samantha N. Jackson ● David R. Haft ● Michiko E. Taga1 Received: 7 June 2018 / Revised: 14 September 2018 / Accepted: 4 October 2018 / Published online: 14 November 2018 © The Author(s) 2018. This article is published with open access Abstract The vitamin B12 family of cofactors known as cobamides are essential for a variety of microbial metabolisms. We used comparative genomics of 11,000 bacterial species to analyze the extent and distribution of cobamide production and use across bacteria. We find that 86% of bacteria in this data set have at least one of 15 cobamide-dependent enzyme families, but only 37% are predicted to synthesize cobamides de novo. The distribution of cobamide biosynthesis and use vary at the phylum level. While 57% of Actinobacteria are predicted to biosynthesize cobamides, only 0.6% of Bacteroidetes have the complete pathway, yet 96% of species in this phylum have cobamide-dependent enzymes. The form of cobamide produced 1234567890();,: 1234567890();,: by the bacteria could be predicted for 58% of cobamide-producing species, based on the presence of signature lower ligand biosynthesis and attachment genes. Our predictions also revealed that 17% of bacteria have partial biosynthetic pathways, yet have the potential to salvage cobamide precursors. Bacteria with a partial cobamide biosynthesis pathway include those in a newly defined, experimentally verified category of bacteria lacking the first step in the biosynthesis pathway.

GENERAL INTRODUCTION 1. Overview of Alzheimer’s disease a. Description/Definition Alzheimer’s disease (AD) is the most common type of age-related disease (aged over 65 years old), accounting for about 55 – 70% of dementia (Bertram, 2007; Bu et al., 2015; Mandell and Green, 2011). AD is characterized by progressive loss of memory and neurodegeneration of the central nervous system, leading to disorder in cognition and behavior of AD patients (Bertram, 2007; Mandell and Green, 2011). The life span of AD patients from onset may last about 10 years but can be as long as 20 years. b. Stages and symptoms of Alzheimer’s disease Stages of AD vary among individual and determination of stages that patients are suffering from is the most importance of AD treatment. The standard approach to classify AD stages relies on a mental status examination, the Mini-Mental State Examination (MMSE) (Folstein et al., 1975; Knopman). AD manifestations can be categorized into three stages with symptoms (López and DeKosky, 2008) presented in Table 1. 1 Table 1.

  • Reclassification of Eubacterium Hallii As Anaerobutyricum Hallii Gen. Nov., Comb
    TAXONOMIC DESCRIPTION Shetty et al., Int J Syst Evol Microbiol 2018;68:3741–3746 DOI 10.1099/ijsem.0.003041 Reclassification of Eubacterium hallii as Anaerobutyricum hallii gen. nov., comb. nov., and description of Anaerobutyricum soehngenii sp. nov., a butyrate and propionate-producing bacterium from infant faeces Sudarshan A. Shetty,1,* Simone Zuffa,1 Thi Phuong Nam Bui,1 Steven Aalvink,1 Hauke Smidt1 and Willem M. De Vos1,2,3 Abstract A bacterial strain designated L2-7T, phylogenetically related to Eubacterium hallii DSM 3353T, was previously isolated from infant faeces. The complete genome of strain L2-7T contains eight copies of the 16S rRNA gene with only 98.0– 98.5 % similarity to the 16S rRNA gene of the previously described type strain E. hallii. The next closest validly described species is Anaerostipes hadrus DSM 3319T (90.7 % 16S rRNA gene similarity). A polyphasic taxonomic approach showed strain L2-7T to be a novel species, related to type strain E. hallii DSM 3353T. The experimentally observed DNA–DNA hybridization value between strain L2-7T and E. hallii DSM 3353T was 26.25 %, close to that calculated from the genomes T (34.3 %). The G+C content of the chromosomal DNA of strain L2-7 was 38.6 mol%. The major fatty acids were C16 : 0,C16 : 1 T cis9 and a component with summed feature 10 (C18 : 1c11/t9/t6c). Strain L2-7 had higher amounts of C16 : 0 (30.6 %) compared to E. hallii DSM 3353T (19.5 %) and its membrane contained phosphatidylglycerol and phosphatidylethanolamine, which were not detected in E.

    TAXONOMIC DESCRIPTION Feng et al., Int J Syst Evol Microbiol 2018;68:3546–3550 DOI 10.1099/ijsem.0.003028 Eubacterium maltosivorans sp. nov., a novel human intestinal acetogenic and butyrogenic bacterium with a versatile metabolism Yuan Feng,1 Alfons J. M. Stams,1,2 Irene Sanchez-Andrea 1 and Willem M. de Vos1,3,* Abstract A novel anaerobic, non-spore-forming bacterium was isolated from a faecal sample of a healthy adult. The isolate, T designated strain YI , was cultured in a basal liquid medium under a gas phase of H2/CO2 supplemented with yeast extract (0.1 g lÀ1). Cells of strain YIT were short rods (0.4–0.7Â2.0–2.5 µm), appearing singly or in pairs, and stained Gram-positive. Catalase activity and gelatin hydrolysis were positive while oxidase activity, indole formation, urease activity and aesculin hydrolysis were negative. Growth was observed within a temperature range of 20–45 C (optimum, 35–37 C), and a pH range of 5.0–8.0 (optimum pH 7.0–7.5). Doubling time was 2.3 h when grown with glucose at pH 7.2 and 37 C. Besides acetogenic growth, the isolate was able to ferment a large range of monomeric sugars with acetate and butyrate as the main end products. Strain YIT did not show respiratory growth with sulfate, sulfite, thiosulfate or nitrate as electron acceptors. The T major cellular fatty acids of the isolate were C16 : 0 and C18 : 0. The genomic DNA G+C content was 47.8 mol%. Strain YI is affiliated to the genus Eubacterium, sharing highest levels of 16S rRNA gene similarity with Eubacterium limosum ATCC 8486T (97.3 %), Eubacterium callanderi DSM 3662T (97.5 %), Eubacterium aggregans DSM 12183T (94.4 %) and Eubacterium barkeri DSM 1223T (94.8 %).

H Molecular tools were developed for rapid, sensitive, and highly specifi c characterization of the human predominant fecal and salivary microbiota. Predominant bacterial, Eubacterium rectale – Blautia coccoides group (Erec), Clostridium leptum group (Clept), and Bacteroides spp. populations of healthy adults were temporally rather stable, showing intra-individual diversity and inter-individual variability. However, rRNA-based denaturing gradient gel electrophoresis (DGGE) profi les showed more temporal instability than DNA-based profi les. Moreover, the diversity of predominant bacteria and Erec-group bacteria was signifi cantly higher in elderly subjects as compared to younger adults. Clostridial populations represented the dominant fecal microbiota of most of the studied subjects. However, the proportion of Erec-group was signifi cantly lower in the constipation type IBS subjects than in the healthy adults. Altogether, the observations indicated that in addition to temporal instability of the active predominant fecal bacterial population, clostridial microbiota may be involved in IBS. Thereafter, the similarity of the salivary and fecal microbiota was studied to assess whether the upper gastrointestinal tract microbiota infl uence the results obtained with DNA-based methods from feces.

Smith Professor in Agricultural Sciences *Signatures are on file in the Graduate School ii Abstract The micronutrient selenium (Se) has been suggested as a promising adjuvant for pharmaconutrient intervention in clinical applications. Use of Se in cancer research and for viral infections has been well documented. It has been less well defined in bacterial infections. The application of the micronutrient as a novel therapeutic is rooted in the fact that adequate and supplemental levels of Se are required to maintain optimal expression of selenoproteins. Selenoproteins are a particular class of proteins which contain Se in the form of the amino acid, selenocysteine. It has been well established that deficiency of Se is deleterious to human health, and in the last two decades a large body of work has been published correlating deficiency with individuals suffering from chronic and in a small number of cases acute bacterial infections.
