  • Diversity and Composition of the Skin, Blood and Gut Microbiome in Rosacea—A Systematic Review of the Literature
    microorganisms Review Diversity and Composition of the Skin, Blood and Gut Microbiome in Rosacea—A Systematic Review of the Literature Klaudia Tutka, Magdalena Zychowska˙ and Adam Reich * Department of Dermatology, Institute of Medical Sciences, Medical College of Rzeszow University, 35-055 Rzeszow, Poland; [email protected] (K.T.); [email protected] (M.Z.)˙ * Correspondence: [email protected]; Tel.: +48-605076722 Received: 30 August 2020; Accepted: 6 November 2020; Published: 8 November 2020 Abstract: Rosacea is a chronic inflammatory skin disorder of a not fully understood pathophysiology. Microbial factors, although not precisely characterized, are speculated to contribute to the development of the condition. The aim of the current review was to summarize the rosacea-associated alterations in the skin, blood, and gut microbiome, investigated using culture-independent, metagenomic techniques. A systematic review of the PubMed, Web of Science, and Scopus databases was performed, according to PRISMA (preferred reporting items for systematic review and meta-analyses) guidelines. Nine out of 185 papers were eligible for analysis. Skin microbiome was investigated in six studies, and in a total number of 115 rosacea patients. Blood microbiome was the subject of one piece of research, conducted in 10 patients with rosacea, and gut microbiome was studied in two papers, and in a total of 23 rosacea subjects. Although all of the studies showed significant alterations in the composition of the skin, blood, or gut microbiome in rosacea, the results were highly inconsistent, or even, in some cases, contradictory. Major limitations included the low number of participants, and different study populations (mainly Asians). Further studies are needed in order to reliably analyze the composition of microbiota in rosacea, and the potential application of microbiome modifications for the treatment of this dermatosis.

  • Long-Read Metagenomics Retrieves Complete Single-Contig Bacterial Genomes from Canine Feces
    Cuscó et al. BMC Genomics (2021) 22:330 https://doi.org/10.1186/s12864-021-07607-0 RESEARCH Open Access Long-read metagenomics retrieves complete single-contig bacterial genomes from canine feces Anna Cuscó1*, Daniel Pérez2, Joaquim Viñes1,2, Norma Fàbregas1 and Olga Francino2 Abstract Background: Long-read sequencing in metagenomics facilitates the assembly of complete genomes out of complex microbial communities. These genomes include essential biologic information such as the ribosomal genes or the mobile genetic elements, which are usually missed with short-reads. We applied long-read metagenomics with Nanopore sequencing to retrieve high-quality metagenome-assembled genomes (HQ MAGs) from a dog fecal sample. Results: We used nanopore long-read metagenomics and frameshift aware correction on a canine fecal sample and retrieved eight single-contig HQ MAGs, which were > 90% complete with < 5% contamination, and contained most ribosomal genes and tRNAs. At the technical level, we demonstrated that a high-molecular-weight DNA extraction improved the metagenomics assembly contiguity, the recovery of the rRNA operons, and the retrieval of longer and circular contigs that are potential HQ MAGs. These HQ MAGs corresponded to Succinivibrio, Sutterella, Prevotellamassilia, Phascolarctobacterium, Catenibacterium, Blautia, and Enterococcus genera. Linking our results to previous gastrointestinal microbiome reports (metagenome or 16S rRNA-based), we found that some bacterial species on the gastrointestinal tract seem to be more canid-specific –Succinivibrio, Prevotellamassilia, Phascolarctobacterium, Blautia_A sp900541345–, whereas others are more broadly distributed among animal and human microbiomes –Sutterella, Catenibacterium, Enterococcus, and Blautia sp003287895. Sutterella HQ MAG is potentially the first reported genome assembly for Sutterella stercoricanis, as assigned by 16S rRNA gene similarity.

  • Putative Mobilized Colistin Resistance Genes in the Human Gut Microbiome Bruno G
    Andrade et al. BMC Microbiology (2021) 21:220 https://doi.org/10.1186/s12866-021-02281-4 RESEARCH ARTICLE Open Access Putative mobilized colistin resistance genes in the human gut microbiome Bruno G. N. Andrade1, Tobias Goris2, Haithem Afli1, Felipe H. Coutinho3, Alberto M. R. Dávila4 and Rafael R. C. Cuadrat5,6* Abstract Background: The high incidence of bacterial genes that confer resistance to last-resort antibiotics, such as colistin, caused by mobilized colistin resistance (mcr) genes, poses an unprecedented threat to human health. Understanding the spread, evolution, and distribution of such genes among human populations will help in the development of strategies to diminish their occurrence. To tackle this problem, we investigated the distribution and prevalence of potential mcr genes in the human gut microbiome using a set of bioinformatics tools to screen the Unified Human Gastrointestinal Genome (UHGG) collection for the presence, synteny and phylogeny of putative mcr genes, and co-located antibiotic resistance genes. Results: A total of 2079 antibiotic resistance genes (ARGs) were classified as mcr genes in 2046 metagenome assembled genomes (MAGs), distributed across 1596 individuals from 41 countries, of which 215 were identified in plasmidial contigs. The genera that presented the largest number of mcr-like genes were Suterella and Parasuterella. Other potential pathogens carrying mcr genes belonged to the genus Vibrio, Escherichia and Campylobacter. Finally, we identified a total of 22,746 ARGs belonging to 21 different classes in the same 2046 MAGs, suggesting multi- resistance potential in the corresponding bacterial strains, increasing the concern of ARGs impact in the clinical settings. Conclusion: This study uncovers the diversity of mcr-like genes in the human gut microbiome.

Aggrey2, Yuming Guo1 and Jianmin Yuan1* 1 State Key Laboratory of Animal Nutrition, College of Animal Science and Technology, China Agricultural University, Beijing, China, 2 NutriGenomics Laboratory, Department of Poultry Science, University of Georgia, Athens, GA, United States Xylan oligosaccharides (XOS) can promote proliferation of Pediococcus acidilactic BCC-1, which benefits gut health and growth performance of broilers. The study aimed to investigate the effect of Pediococcus acidilactic BCC-1 (referred to BBC) and XOS on the gut metabolome and microbiota of broilers. The feed conversion ratio of BBC group, XOS group and combined XOS and BBC groups was lower Edited by: than the control group (P < 0.05). Combined XOS and BBC supplementation (MIX Michael Gänzle, group) elevated butyrate content of the cecum (P 0.05) and improved ileum University of Alberta, Canada < morphology by enhancing the ratio of the villus to crypt depth (P 0.05). The 16S Reviewed by: < Richard Ducatelle, rDNA results indicated that both XOS and BBC induced high abundance of butyric Ghent University, Belgium acid bacteria. XOS treatment elevated Clostridium XIVa and the BBC group enriched Shiyu Tao, Huazhong Agricultural University, Anaerotruncus and Faecalibacterium. In contrast, MIX group induced higher relative China abundance of Clostridiaceae XIVa, Clostridiaceae XIVb and Lachnospiraceae. Besides, *Correspondence: MIX group showed lower abundance of pathogenic bacteria such as Campylobacter.

  • Increased Abundance of Sutterella Spp. and Ruminococcus Torques In
    Wang et al. Molecular Autism 2013, 4:42 http://www.molecularautism.com/content/4/1/42 SHORT REPORT Open Access Increased abundance of Sutterella spp. and Ruminococcus torques in feces of children with autism spectrum disorder Lv Wang1, Claus T Christophersen2, Michael J Sorich1, Jacobus P Gerber1, Manya T Angley1 and Michael A Conlon2* Abstract Background: A recent report indicated that numbers of Sutterella spp. are elevated in gastrointestinal biopsies taken from children with autism spectrum disorder (ASD). We have recently reported changes in the numbers of some bacteria within the stool of ASD children, and now examine whether numbers of Sutterella spp. and some other mucosa-associated bacteria linked with gastrointestinal disease (Ruminococcus gnavus and Ruminococcus torques) are also altered in the stool of these children. Findings: We show that numbers of Sutterella spp. are elevated in feces of ASD children relative to controls, and that numbers of R. torques are higher in the children with ASD with a reported functional gastrointestinal disorder than those without such a disorder. Conclusions: We show further evidence of changes in the gut microbiota of children with ASD and confirm that the abundance of Sutterella spp. is altered in stool. Keywords: Autism spectrum disorder, Gut, Feces, Microbiota, Sutterella Findings abundance of S. wadsworthensis in colonic biopsies of Autism spectrum disorder (ASD) is a neurodevelopmental adults with inflammatory bowel disease (IBD) was not disorder where there is evidence of gastrointestinal (GI) different from controls, Sutterella appeared to be more disturbance in many affected individuals. Several studies prevalent in the human gut than previously reported [10].
