Vibrio vulnificus, a ubiquitous inhabitant of coastal marine environments, has been isolated from a variety of sources. It is an opportunistic pathogen of both marine animals and humans. Here, the genome sequence of V. vulnificus Env1, an environmental isolate resistant to predation by the ciliate Tetrahymena pyriformis, is reported. Copyright © 2018 Noorian et al.
Karnal bunt of wheat is an internationally quarantined fungal pathogen disease caused by Tilletia indica and affects the international commercial seed trade of wheat. We announce here the first improved draft genome assembly of a monoteliosporic culture of the Tilletia indica fungus, consisting of 787 scaffolds with an approximate total genome size of 31.83 Mbp, which is more accurate and near to complete than the previous version.

Pseudomonas stutzeri strain SGAir0442 was isolated from tropical air samples collected in Singapore. It is a Gram-negative denitrifying bacterium and an opportunistic human pathogen. Its complete genome consists of one chromosome of 4.52?Mb, containing 4,129 protein-coding genes, 12 rRNA subunits, and 62 tRNAs. Copyright © 2018 Kee et al.
Here, we report the complete genome sequence of the pathogenic Aeromonas salmonicida subsp. masoucida strain RFAS1, isolated from black rockfish and showing signs of furunculosis. Sequencing with the PacBio platform yielded a circular chromosome of 4,783,004?bp and two plasmids (70,968?bp and 63,563?bp) harboring 4,411, 67, and 71 protein-coding genes, respectively.

We report here the complete genome sequence of Klebsiella quasipneumoniae strain S05, a bacterium capable of producing membrane fouling-causing soluble substances and capable of respiring on oxygen, nitrate, and an anodic electrode. The genomic information of strain S05 should help predict metabolic pathways associated with these unique biological properties of this bacterium. Copyright © 2018 Kitajima et al.
Achromobacter spanius is a newly described, non-fermenting, Gram-negative, coccoid pathogen isolated from human blood. Whole-genome sequencing of the A. spanius type strain was performed to investigate the mechanism of pathogenesis of this strain at a genomic level.The complete genome of A. spanius type strain DSM 23806T was sequenced using single-molecule real-time (SMRT) DNA sequencing.The complete genome of DSM 23806T consists of one circular DNA chromosome of 6425783bp with a G+C content of 64.26%. The entire genome contains 5804 predicted coding sequences (CDS) and 55 tRNAs. Genomic island (GI) analysis showed that this strain encodes several important pathogenesis- and resistance-related genes.These results strongly suggest that GIs provide some fitness advantages in A. spanius type strain DSM 23806T. This report provides an extensive understanding of A. spanius at a genomic level as well as an understanding of the evolution of A. spanius.

Serratia marcescens strain SGAir0764 was isolated from a tropical air sample collected in Singapore. The complete genome, sequenced on the PacBio RS II platform, consists of one chromosome with 5.1?Mb and one plasmid with 76.4?kb. Genome annotation predicts 4,723 protein-coding genes, 89 tRNAs, and 22 rRNAs. Copyright © 2018 Gaultier et al.
Rhizobia are a paraphyletic group of soil-borne bacteria that induce nodule organogenesis in legume roots and fix atmospheric nitrogen for plant growth. In non-leguminous plants, species from the Rhizobiales order define a core lineage of the plant microbiota, suggesting additional functional interactions with plant hosts. In this work, genome analyses of 1,314 Rhizobiales isolates along with amplicon studies of the root microbiota reveal the evolutionary history of nitrogen-fixing symbiosis in this bacterial order. Key symbiosis genes were acquired multiple times, and the most recent common ancestor could colonize roots of a broad host range. In addition, root growth promotion is a characteristic trait of Rhizobiales in Arabidopsis thaliana, whereas interference with plant immunity constitutes a separate, strain-specific phenotype of root commensal Alphaproteobacteria. Additional studies with a tripartite gnotobiotic plant system reveal that these traits operate in a modular fashion and thus might be relevant to microbial homeostasis in healthy roots.

Vitreoscilla sp. strain C1 is of historical importance as the source of the first prokaryotic hemoglobin identified. Vitreoscilla spp. rely on their hemoglobin and cytochrome oxidase to grow in microaerobic environments despite their aerobic nature. To help characterize this historically relevant strain, we sequenced the complete Vitreoscilla sp. strain C1 genome.
We report here the complete genome sequence of Stenotrophomonas maltophilia AB550, a multidrug- and solar radiation-resistant strain isolated from the effluents of an urban wastewater treatment plant in Western Australia. The genome consists of a single 4.9-Mb chromosome.
Antimicrobial resistance is a major problem worldwide. Understanding the interplay between drug-resistant pathogens, such as Acinetobacter baumannii and related species, potentially acting as environmental reservoirs is critical for preventing the spread of resistance determinants. Here we report the complete genome sequence of a multidrug-resistant bacteriophage-propagating strain of Acinetobacter radioresistens.
Methicillin-resistant Staphylococcus aureus (MRSA) clonal complex 8 (CC8) sequence type 239 (ST239) represents a predominant hospital-associated MRSA sublineage present worldwide. The Canadian epidemic MRSA strains CMRSA3 and CMRSA6 are moderately virulent members of this group but are closely related to the highly virulent strain TW20. Whole-genome sequencing of CMRSA3 and CMRSA6 was conducted to identify genetic determinants associated with their virulence.
This is the announcement of draft genome sequences for Staphylococcus aureus strains belonging to sequence type 97 (ST97) and ST71. These sequence types are commonly associated with bovine mastitis, and the strains were isolated in Ireland in 2010 from the milk of cows with clinical mastitis.
Carbapenem-resistant Pseudomonas aeruginosa is defined as a textquotedblleftcriticaltextquotedblright priority pathogen for the development of new antibiotics. Here we report the complete genome sequence of an extensively drug-resistant, Verona integron-encoded metallo-ß-lactamase-expressing isolate belonging to the high-risk sequence type 233.
