The strain, designated LIND7HT, grew at 20–45 6C (optimum 35–40 6C) and at pH 5.0–8.5 (optimum pH 6.5–7.5). It did not require NaCl for growth, but was able to grow in the presence of up to 2 % NaCl. Sulfate, thiosulfate, elemental sulfur, sulfite, nitrate and nitrite were not used as terminal electron acceptors. -

Accepted: November 6, 2015 Abstract Porphyromonads play an important role in human periodontal disease and recently have been shown to be highly prevalent in canine mouths. Porphyromonas cangingivalis is the most prevalent canine oral bacterial species in both plaque from healthy gingiva and at University of Technology, Sydney on January 17, 2016 plaque from dogs with early periodontitis. The ability of P. cangingivalis to flourish in the different environmental conditions char- acterized by these two states suggests a degree of metabolic flexibility. To characterize the genes responsible for this, the genomes of 32 isolates (including 18 newly sequenced and assembled) from 18 Porphyromonad species from dogs, humans, and other mammals were compared. Phylogenetic trees inferred using core genes largely matched previous findings; however, comparative genomic analysis identified several genes and pathways relating to heme synthesis that were present in P. cangingivalis but not in other Porphyromonads. Porphyromonas cangingivalis has a complete protoporphyrin IX synthesis pathway potentially allowing it to syn- thesize its own heme unlike pathogenic Porphyromonads such as Porphyromonas gingivalis that acquire heme predominantly from blood. -

To date, there is no taxonomically broad survey of endosymbionts in weevils, which preclude any systematic understanding of the diversity and evolution of endosymbionts in this large group of insects, which comprise nearly 7% of described diversity of all insects. We gathered the largest known taxonomic sample of weevils representing four families and 17 subfamilies to perform a study of weevil endosymbionts. We found that the diversity of endosymbionts is exceedingly high, with as many as 44 distinct kinds of endosymbionts detected. We recovered an ancient origin of association of Nardonella with weevils, dating back to 124 MYA. We found repeated losses of this endosymbionts, but also cophylogeny with weevils. We also investigated patterns of coexistence and coexclusion. INTRODUCTION Weevils (Insecta: Coleoptera: Curculionoidea) host diverse bacterial endosymbionts. -

The Microbiome of the Footrot Lesion in Merino Sheep Is Characterized by a Persistent Bacterial Dysbiosis T ⁎ Andrew S
Veterinary Microbiology 236 (2019) 108378 Contents lists available at ScienceDirect Veterinary Microbiology journal homepage: www.elsevier.com/locate/vetmic The microbiome of the footrot lesion in Merino sheep is characterized by a persistent bacterial dysbiosis T ⁎ Andrew S. McPherson, Om P. Dhungyel, Richard J. Whittington Farm Animal Health, Sydney School of Veterinary Science, Faculty of Science, The University of Sydney, 425 Werombi Rd, Camden, New South Wales, 2570, Australia ARTICLE INFO ABSTRACT Keywords: Footrot is prevalent in most sheep-producing countries; the disease compromises sheep health and welfare and Footrot has a considerable economic impact. The disease is the result of interactions between the essential causative Merino agent, Dichelobacter nodosus, and the bacterial community of the foot, with the pasture environment and host Sheep resistance influencing disease expression. The Merino, which is the main wool sheep breed in Australia, is Microbiome particularly susceptible to footrot. We characterised the bacterial communities on the feet of healthy and footrot- Dichelobacter nodosus affected Merino sheep across a 10-month period via sequencing and analysis of the V3-V4 regions of the bacterial 16S ribosomal RNA gene. Distinct bacterial communities were associated with the feet of healthy and footrot- affected sheep. Infection with D. nodosus appeared to trigger a shift in the composition of the bacterial com- munity from predominantly Gram-positive, aerobic taxa to predominantly Gram-negative, anaerobic taxa. A total of 15 bacterial genera were preferentially abundant on the feet of footrot-affected sheep, several of which have previously been implicated in footrot and other mixed bacterial diseases of the epidermis of ruminants. -

Supplementary Materials S1 Clinical details recorded, Sampling, DNA Extraction of Microbial DNA, 16S rRNA gene sequencing, Bioinformatic pipeline, Quantitative Polymerase Chain Reaction Clinical details recorded In addition to the microbial specimen, the following clinical features were also recorded for each patient: age, gender, infection type (primary or secondary, meaning initial or revision treatment), pain, tenderness to percussion, sinus tract and size of the periapical radiolucency, to determine the correlation between these features and microbial findings (Table 1). Prevalence of all clinical signs and symptoms (except periapical lesion size) were recorded on a binary scale [0 = absent, 1 = present], while the size of the radiolucency was measured in millimetres by two endodontic specialists on two- dimensional periapical radiographs (Planmeca Romexis, Coventry, UK). Sampling After anaesthesia, the tooth to be treated was isolated with a rubber dam (UnoDent, Essex, UK), and field decontamination was carried out before and after access opening, according to an established protocol, and shown to eliminate contaminating DNA (Data not shown). An access cavity was cut with a sterile bur under sterile saline irrigation (0.9% NaCl, Mölnlycke Health Care, Göteborg, Sweden), with contamination control samples taken. Root canal patency was assessed with a sterile K-file (Dentsply-Sirona, Ballaigues, Switzerland). For non-culture-based analysis, clinical samples were collected by inserting two paper points size 15 (Dentsply Sirona, USA) into the root canal. Each paper point was retained in the canal for 1 min with careful agitation, then was transferred to −80ºC storage immediately before further analysis. Cases of secondary endodontic treatment were sampled using the same protocol, with the exception that specimens were collected after removal of the coronal gutta-percha with Gates Glidden drills (Dentsply-Sirona, Switzerland). -

Many of the bacterial species detected in metagenomic analyses of DD lesions are difficult to culture, and their antimicrobial resistance status is largely unknown. Recently, a novel proximity ligation-guided metagenomic approach (Hi-C ProxiMeta) has been used to identify bacterial reservoirs of antimicrobial resistance genes (ARGs) directly from microbial communities, without the need to culture individual bacteria. The objective of this study was to track tetracycline resistance determinants in bacteria involved in DD pathogenesis using Hi-C. A pooled sample of macerated tissues from clinical DD lesions was used for this purpose. Metagenome deconvolution Citation: Beyi, A.F.; Hassall, A.; ≥ Phillips, G.J.; Plummer, P.J. Tracking using ProxiMeta resulted in the creation of 40 metagenome-assembled genomes with 80% complete Reservoirs of Antimicrobial genomes, classified into five phyla. Further, 1959 tetracycline resistance genes and ARGs conferring Resistance Genes in a Complex resistance to aminoglycoside, beta-lactams, sulfonamide, phenicol, lincosamide, and erythromycin Microbial Community Using were identified along with their bacterial hosts. -
